Gas water heater on propane - and access to natural gas is not needed

How does a liquefied gas column work

Manufacturers produce several flow-through and storage gas boilers capable of running on propane. There are universal models of dispensers that operate quietly on liquefied and main gas, after re-equipment and reconfiguration.
The difference between main gas water heaters and liquefied ones in the burner design. To understand the difference, you need to imagine exactly how fuel is burned:

• It is not the gas itself that burns, but the gas-air mixture, which is prepared when passing from the nozzle to the burner nozzle.
• The proportions of methane or propane and oxygen must be strictly observed. A mixture rich in air will burn poorly, poor smoke.
• The rate of supply of propane and methane to the burner is different. Bottled gas is supplied at a pressure several times higher than that produced by a household gas pipeline. Accordingly, in order to create normal conditions for fuel combustion, it is necessary to reduce the propane feed rate, to stabilize the pressure, which is achieved by changing the nozzles and installing a reducer.

If we talk about the technical operating conditions, then the possibility of installing an instantaneous or storage water heater for liquefied gas exists in any private house. Unlike the connection to the main gas, there is no need for various permits and project preparation. The boiler can be connected to one or more cylinders,.
Reviews of liquefied gas dispensers show that there is a working nuance, which is often not taken into account when connecting. It consists in the following. Propane is pumped into cylinders under pressure, whereby it becomes a liquid. The gas fills the container approximately ⅔. The liquid evaporates from the surface, after which it enters the gearbox and from there is fed to the water heater burner.

The difficulty lies in the fact that evaporation occurs with simultaneous extraction of heat. As a result, at high fuel consumption, freezing of the cylinder walls is observed. How to solve the problem is described in the subheading describing the nuances of the connection.

How to convert a column from methane to propane

The re-equipment is carried out by replacing some of the units of the water heater and the correct connection to the gas cylinder installation. Conversion to propane requires:

• change nozzles on the main burner, depending on the boiler model, there are 12-15 of them;
• if a semi-automatic ignition system is used, the jets on the wick are replaced.

In the same way, you can convert a conventional gas water heater from natural to liquefied gas. The difference is that in the universal models, the factory kit already contains nozzles and jets of the required diameter.
Setting the instantaneous water heater for operation on liquefied gas is carried out using a mechanical control unit. On the body of the water heater there are rotary knobs or levers that regulate the gas pressure supplied to the burner. The optimal mode is considered to be when the tongues of flame have a bluish-blue color.

What is the consumption of propane in a gas water heater

The exact costs are indicated in the passport for the boiler. For example, Bosh gas flow dispensers, powered by bottled gas and having a capacity of 25 kW, continuously consume 1 cylinder of fuel per 50 liters for 10 hours.
The cost can be influenced by the type of fuel (winter or summer), its quality. Gas consumption in independently converted water heaters that are not designed for propane combustion is usually 5-10% higher.Mistakes made when connecting equipment are also reflected in costs.

To meet the needs for hot water supply for 2-3 people, subject to moderate use of a water heater, the consumption of liquefied gas will be one 50 liters. balloon / month

Conclusions and useful video on the topic

From this video you can find out how long it takes for the water to boil, and, therefore, how long a propane cylinder with a burner will last:

Before calculating the time for which a propane cylinder of a certain volume will last, it is necessary to find out the maximum flow rate of the gas equipment used. Often this information is indicated in the technical documentation of the device, whether it is a gas stove or a heating boiler.

According to the formula, to calculate the time of using a gas cylinder, it is necessary to divide the amount of propane inside the cylinder by the fuel consumption of a specific gas appliance. Based on this, it is possible to calculate how long it will last for both a traveling cylinder for a gas burner and a household 50 liter cylinder for using gas appliances.

If you have had to calculate the required volume of gas more than once, please share your experience with our readers, tell us how accurate the calculations turned out to be. You can leave a comment or our experts in the appropriate field after the article.

How to choose a liquefied gas column

If you plan to purchase a boiler for connection to bottled fuel, it is better to immediately purchase one adapted for the use of propane. The manufacturer's instructions will indicate that the column is universal and can be switched between natural and liquefied gas. When choosing, they also take into account the principle of operation, features of the internal device and other technical and operational characteristics.
The following aspects are taken into account:

After choosing according to technical and operational characteristics, you can proceed to the selection of a suitable model of a water heater by manufacturer. Below is a column rating based on customer feedback.

Models of gas instantaneous water heaters for liquefied gas:

• BOSCH WR 10-2P is distinguished by its compact size and impeccable build quality. There is a flame modulation function to maintain a constant outlet water temperature, regardless of the pressure in the pipeline. An atmospheric burner is used.

Flowing gas water heaters with the ability to work from liquefied gas are produced by foreign and domestic companies. Storage boilers are manufactured exclusively abroad.

What volume to choose a gas cylinder

If we proceed solely from the running costs of propane, then it will be enough to install one 50 liter cylinder. Even with uneconomical consumption of liquefied gas, the fuel should be enough for 10-15 days. And this is provided for a large family of 4-5 people. The technical passport of the water heaters indicates that a 50 liter gas cylinder is enough for 10-12 hours of continuous operation.
Experts recommend connecting a propane column through a ramp. So, it is possible to reduce the load during the operation of the geyser from one to several gas cylinders, evenly distributing the fuel consumption and preventing freezing of the walls and the gearbox. The ramp connection allows the installation of several smaller containers of 25/40 l each. Or, alternatively, use 50 l cylinders connected in a bundle with each other.

How to connect a column to a gas cylinder

When installing, take into account the peculiarities of storage and combustion of propane. The column will operate on bottled gas only when the supply pressure drops to 0.2-0.3 mbar, and the nozzles are replaced. It is important to prevent freezing of the cylinders. To ensure the described conditions, the connection of the liquefied gas column is carried out in accordance with the following diagram:

• cylinders are connected through the ramp, several from 2-4 pcs .;
• an adjustable reducer is installed to normalize the pressure.

If you connect a gas cylinder to a gas flow or storage water heater, according to the scheme described above, replace the jets on the wick and nozzles on the main burner, adjust the fuel and water supply, you can achieve stable operation of the column after conversion to propane.

Everyone who is faced with interruptions or lack of hot water supply is thinking about purchasing a heater. The optimal choice for many of our compatriots is a flow-through heating device that runs on gas. Although in most cases such devices use natural gas for their operation, there are models that can operate on liquefied gas.

Choosing a travel gas cylinder

Today, many manufacturers offer special camping gas cylinders that allow not only to cook food, but also to heat the tent when a person is in nature. On the Internet, you can find both small 220 g propane containers and 5 l cylinders with a built-in burner.

Unlike a burner, such a mini gas cooker is designed for containers of any size, since it has a stable grid for dishes.

Despite the convenience of a camping gas stove, small cylinders with a burner are most suitable for mountain travel, since it will be somewhat impractical to take a mini-stove with you.The volume of gas consumed is calculated depending on the duration of the trip, the purpose of using the gas, and the number of gas consumers, depending on which the volume of the vessel will change.

If you don't know how many days a 220-gram gas cylinder is enough, then such a small cylinder will be enough for a three-day fishing trip, but it is only suitable for cooking. However, in this case, you should go fishing by car so that you can spend the night in the cabin, and thus save on gas.

The required volume of the cylinder will be calculated depending on the rate of gas consumption per day by one person. If you choose camping gas burners, then you should understand that they are often used to boil small volumes of water, so when traveling with a company, it is better to give preference to a 5 liter cylinder, to which you can connect a gas stove with one burner.

The formula for calculating the consumed gas

When buying a gas burner for hiking, the manufacturer indicates how many grams per hour the burner consumes. Therefore, if you want to clearly calculate how much gas you will need on your trip, it is better to purchase just such a gas cylinder with a burner.

You can study information regarding the performance of the burner in the product description on the page of any online store.

Such a camping gas burner can even fit into a small backpack, while its gas consumption is about 30-40 g less than that of a mini-stove

To calculate the volume of gas consumed, you need to know only two parameters: fuel consumption (grams per hour) and the boiling time of 1 liter of water (in minutes). Based on this knowledge, you can roughly calculate how long a propane 5 liter gas cylinder lasts when going on a hike or fishing.

According to the information from the product description, the average burner consumes 110 g / h, while 1 liter of water boils in 4.5 minutes. In this case, we will rely exclusively on time, since the amount of propane consumed depends on it. Let's say there is a need to cook porridge and boil water twice for tea for a group of 10 people.

To prepare porridge, you must first boil 3.5 liters of water, which will need to be multiplied by 4.5 (boiling time for 1 liter of water), which is equivalent to 15 minutes. Another 15 minutes is allotted for cooking porridge, while for tea, the water should only come to a boil.

One meal will take 30 minutes to prepare, and the same amount of time will be required for two kettles of tea. In total, the total time for preparing a full meal for 10 people is 1 hour, respectively, we consume 110 g of propane.

When buying a travel gas cylinder, it is important to pay attention to the information located on the packaging, and especially the total weight of the cylinder with the burner

According to the data taken from the stamp on an ordinary 5 liter cylinder, there is 2.3 kg of pure propane inside the container. To calculate the exact weight of propane, you need to weigh the empty cylinder, then subtract the resulting number from the total weight of the burner cylinder.

With two meals a day, you will need to use 220 g, which means that a 450 gram balloon will be enough for a two-day hike. There may be errors in the manufacture of such travel cylinders, so it is better to choose a cylinder with a large volume in case of unforeseen circumstances.

Therefore, if a 5 liter cylinder holds 2.3 kg of gas, then for cooking food for 10 people, this volume of gas will be enough for about 10 days. In this case, gas is consumed only for cooking, without the need to heat the tent or cabin.

The main factor in calculating the gas used

If, for example, a camping gas cylinder is equipped with a built-in burner, which has a set amount of gas consumed per hour, then when using a regular cylinder, a conventional mini gas stove with one burner will be used.

The gas consumption of such a device can vary from 130 to 150 g / h, while the boiling time for 1 liter of water will be less than 4.5 minutes.

For one person, a 220 gram bottle may be enough for a two-day hike, if you use gas exclusively for cooking.

Many travelers often take with them on a hike the popular model of the mini-cooker "Tourist", which is equipped with just one burner for cooking food in containers of any size. Camping gas burners are designed only for the capacity of a certain displacement, so in this case the mini-stove will be much more practical.

The gas consumption of such a tile is 150 g / h, which means that when connected to a 5 liter cylinder, 2.3 kg of propane will be enough for 15 hours of continuous use.

We also recommend reading our other article, where we described in detail how to refuel gas cartridges for burners. Read on for more details.

Gas bottle consumption in the mountains

A conventional propane cylinder with a burner will heat the water twice as long in strong winds, so cylinders with a mixture of several types of gas are sold for traveling in especially difficult conditions. Thus, the use of gas at an altitude of up to 3,500 meters above the ground implies the purchase of a gas cylinder with a mixture of butane and propane.

If you climb even higher, then the gas will simply freeze, due to which its efficiency will significantly decrease. In this case, you will need to purchase a cylinder with a mixture of propane, butane and isobutane.

The more impurities in propane, the less pure gas is left for cooking, which increases the duration of boiling.

That is, at an altitude of more than 3,000 meters, it is worth setting an error factor of 50% in the calculations, even if the information on the cylinder itself does not say anything about it.

If 450 g of ordinary propane is enough for exactly 2 days, then the bottle with butane and isobutane impurities will run out after the completion of the second cooking for the whole company.

Is it possible to change the column for a different type and gas pressure?

Many dispensers can be adjusted to use liquefied gas, but this must be done by a service organization with an appropriate certificate. In addition, the changeover is necessarily carried out only using a set of parts from the speaker manufacturer.

Conversion work includes replacing the manifold jets (nozzles), so that as a result, nozzles are installed on the apparatus, the diameter of the holes of which will be suitable for the desired type of gas and its pressure. During the changeover, the device must be turned off, and the shut-off valve of the gas pipeline is closed. After finishing the changeover, the tightness of all connections should be assessed. In addition, the type of gas, the date of the changeover and the organization that carried it out are indicated on the device and in its instructions.

See the start-up and operation of a liquefied gas water heater in the following video using a gas boiler as an example.

Installation and assembly

As soon as the column is configured to operate on liquefied gas, you should pay attention to the characteristics of the gas cylinder:

• It must certainly have a reducer, while its stabilization pressure must be 300 mm wc.
• The minimum value of the productivity of the vapor phase at the cylinder should be 1 m³ per hour.

In addition, a flexible hose with a minimum internal diameter of 12 mm and a length of up to 2.5 m should be selected. This hose must be able to withstand the gas being used, taking into account the set temperature and the set pressure. For this, a hose certified for operation with LPG is selected. During connection, it must not be twisted or bent near the ferrules.

Often, water heaters are purchased for use in summer cottages, for work “in the field”. Accordingly, there may be no centralized gas supply in dacha cooperatives and settlements. There is a way out - to install an electric water heater or choose a gas water heater with the ability to connect to a cylinder. Can a gas water heater work from a gas cylinder? Yes, if the manufacturer has provided such an option. How to connect it and what fuel to use - you will find answers to these questions below.

You can also reconfigure an existing column. To do this, carefully read the instructions in the final part of the article.

The substances used to heat the water are called propane and butane. These are derivatives released during the processing of "black gold" - oil (gasoline, gas). Both pure technical butane and a mixture of butane and propane in their winter or summer versions are used.

Gases, when compressed, pass into a liquid state, occupy a smaller volume. That is why this type of fuel is often called "liquefied".

When the pressure decreases, the gas turns into a vapor state. Since gas tends to expand at high temperatures, the cylinder is usually 85% full. If you think that you have not been "refilled" with fuel, this is for your own safety.

Fact! There will always be a layer of vaporous gas above the liquid gas.

Gas cylinder - 100% summer cottage option

Often, an instantaneous water heater powered by bottled gas is the only way to heat water for a summer residence. Of course, no one is about natural heat from the sun, but what to do in winter? Exit - boiler or gas water heater.

As for the electric water heater, it is not always possible to make a choice in its favor for a simple reason: not all summer cottages have an ideal power grid that would work without interruptions and would not annoy with voltage surges. This is partly to blame for those who use electric motors for watering, electric saws, air conditioners and other powerful appliances. A boiler or an electric flow heater is not always a profitable solution.

It is not a problem to get a cylinder with a gas mixture. Moreover, the majority of domestic manufacturers (and not only) produce gas equipment that works regardless of which gas is used - ordinary or liquefied.

Consumption rates for HBO-4

Experts usually call the figure 10-20% relative to gasoline consumption (in liters). The explanation for this is simple. The first clients of gas workers were taxi drivers, for whom the car is, first of all, a source of income. And therefore, every liter counts, it is even better if you manage to save it.

The car park mainly consisted of inexpensive products of the Korean car industry, Daewoo small cars of the Nexia and Lanos models, on which it was possible to adjust the gas consumption for the 4th generation LPG to the desired 10%. At the same time, the owners did not have any special requirements for dynamic performance, speed, they were interested in other criteria for the operation of the motor.

Further. Every self-respecting manufacturer of gas-cylinder units, in response to a question about the standardized consumption after switching to gas, will name an indicator of 1.2 in relation to driving on regular fuel. Setting the ignition timing (mounting the variator) will allow you to win another 5 to 10% - no more.

Important. Many drivers incorrectly determine the consumption - hence the misconceptions about its value. You cannot measure consumption until the cylinder is completely empty: first you need to fill the full tank with gas, drive approximately 200-250 km, and then refuel again. It is advisable not to change the dressings - this may affect the purity of the experiment. The ratio of the distance traveled in km to the cost in liters will give an indicator of consumption.

The gluttony of a four-wheeled horse also depends on the state of the environment, this is pure physics: at low temperatures, gas consumption will always be greater. Ultimately, this parameter fits into the indicated 10-20%. This is especially necessary to remember for those who want to save the engine resource and not speed up the overhaul. Incorrect setting, among other things, increases the temperature of the waste products of combustion by almost 2 times - up to 1400 ° C, and all this due to the depletion of the mixture.

Connecting equipment to the cylinder

Before you start connecting the equipment yourself, make sure that the model really fits.

Other brands of acceptable equipment:, (almost all the latest models). The instructions for the Bosch columns indicate that a 50-liter cylinder will last for 10 hours of stable operation at a power of 25 kW. The conversion kit for Bosch speakers can be purchased from an authorized service center.

If it is necessary to carry out work on retooling equipment, replacing the manifold nozzles and assessing the tightness of the joints, they must be done strictly according to the rules. The nozzles should be of a smaller diameter: as in gas stoves, the pressure produced by liquefied gas reducers is 2-3 times higher than when natural gas is supplied through pipes. At the same time, the calorific value of liquid fuel is 1.5 times stronger than that of natural gas.

On the equipment, you need to put the date of rework - day, month and year. The type of gas suitable for use is also indicated.

The connection diagram of the cylinder to the gas pipeline requires it to have a reducer with a pressure stabilization of 300 mm of water. Art. and a minimum productivity of the vapor phase of one cubic meter per hour.

Parameters of the hose connecting the gas equipment with the fuel tank:

• 250 cm - minimum length;
• 1.2 cm is the smallest permissible inner tube diameter.

Important! When installing the hose tube, never bend or twist it. Even if bending is required, use adapters and pay attention to the radius - it cannot be less than 9 cm along the outer arc. Also, do not bend the hose earlier than 5 cm from the end of its ends.

Please note that on the forums on the network there is information of the following nature: if you reconfigure the column correctly and carry out the work without flaws, problems with water pressure may arise and the column will not start. Then you will need an additional installation of a pump that builds up pressure.

When installing the shut-off valve, remember that it must be easily accessible so that the user can quickly close it in the event of an emergency.

After completing the installation work, check the tightness of the connections and carry out a test run of the equipment.

LPG gas water heaters of this model have a flue-free, turbocharged evaporative exhaust system. The burnt gas escapes through the coaxial pipe. The big advantage is that the device can operate on both flowing and liquefied gas. The equipment is not included in the kit, you will have to buy it separately. Reconfiguration is easy, and the quality of work from changing the fuel does not decrease. The gas water heater is equipped with technical innovations and functions: a draft sensor and flame extinguishing, overheating and gas supply fuses. An electronic control board is installed here, incredibly sensitive to power surges. The cost of the equipment is quite high, and any power surge can make it unusable.

Advice! To protect yourself from possible breakdown of the column due to a drop in electricity, it is worth getting a stabilizer.

This instantaneous LPG gas water heater has a small capacity for its capacity. Because of this, the high temperature can only be in one tap. If you turn on several at the same time, both will get an unsatisfactory result. This model is the cheapest of the entire model range of the company. The main disadvantage is the lack of outlet temperature control. The column is quite noisy when set on fire and in operation. Even with a small trickle, it works, but a loud bang is heard. Among the advantages - low price, ease of management and further maintenance, the ability to work on natural and liquefied gas. There are more successful examples in the assortment of the company.They cost a little higher, but the usability is much better.

Now we will figure out the principle of operation of a flow-through gas water heater running on liquefied gas (aka cylinder).

The owners of private houses and summer cottages are constantly choosing the best option for supplying users with hot water. One of these options is a flow-through water heater that operates on.

Instantaneous water heater Vektor JSD

Principle of operation

The main function of gas water heaters is to heat water as soon as possible. It looks like a housing that contains a combustion chamber,.

In a liquefied gas column, water is heated while it flows through a heat exchanger, which in turn is heated by a burner. In addition, the device has such elements as: a water cooling system, a control unit, temperature, pressure and draft sensors. Thanks to the electronic security system, the operation of the column is monitored throughout its entire operation.

Installation

Before installing a gas instantaneous water heater for liquefied gas, you need to deal with the cylinder. It is important that it meets the following characteristics:

1. There must be a gearbox on it.
2. Pressure equal to 300 mm. water Art.
3. The minimum value of the capacity of the first phase of the cylinder should be 1 m³ per hour.

It is also necessary to purchase a flexible hose with an internal diameter of at least 12 mm and a length not exceeding 2.5 m. This hose must be able to withstand the gas at the required temperature and required pressure.

A gas shut-off valve must be installed in front of the column itself. After you complete the installation, be sure to check all sections of the connections and the hose so that, in case of any malfunctions, they can be eliminated immediately.

If you have experience working with gas equipment, then you can install the gas column yourself. If not, you should contact a specialist.

Connection to LPG bottle

First of all, you need to make sure that your gas column is set to use the gas that is present in the cylinder. If required, work is performed on the changeover of the column with the replacement of the manifold nozzles and the assessment of the tightness of the connections. At the same time, the date of the readjustment and the type of gas that can be used in the device must be marked on the equipment.

The cylinder, which will be connected to the gas water heater, must be equipped with a reducer with a stabilization pressure of 300 mm of water column, as well as a minimum vapor phase capacity of 1 m³ per hour. They also pay attention to the selection of the hose - its length should be up to two and a half meters, and the inner diameter should be from 12 millimeters. It is important to purchase a hose that will withstand working with a column on a gas cylinder.

When installing the hose, do not bend or twist it. If the hose has to be installed with a bend, for this they use adapters and monitor the bending radius (it should not be less than 90 mm along its outer line). In addition, the hose must not bend within 50 mm of the ends of the ferrules.

The installation of a gas shut-off valve should be carried out in front of the column so that it is easy to get to this valve. After completing the installation work, the hose and other connections should be checked for timely detection of leaks. Only then can the column be used to heat water.

As a result, the operation of an instantaneous water heater on liquefied gas will allow autonomously supplying a house or a summer cottage with hot water.

How to reduce gas consumption

Methods to help reduce the cost of refueling a car, for the most part, are simple and unpretentious. This is also the answer to the standard question: high gas consumption of 4 generation HBO - what are the reasons.

Firstly, a passenger car, even converted to gas, is still a small car for transporting passengers. There is no need to turn the car into a truck to deliver bags of potatoes, sugar or other heavy loads: this will inevitably lead to an increase in fuel consumption. In addition, an overloaded car forces the engine to work in extreme conditions, losing on average up to 12% of power. Even computerized gas supply systems, which include 4th generation units, are not able to cope with overruns in this situation. Moreover, according to experts, as the load increases, it literally grows exponentially.

Secondly, any mechanism needs maintenance - and, of course, qualified, using special equipment, and not a garage service. You need to make it a rule to do diagnostics every six months, check the condition of the cylinder, sensors, nozzles, highways and electronics. For example, quite scanty, but still an increase in consumption by 1-2 liters may occur due to an increase in the normalized gap in the membranes. Do not forget about the quality of the fuel: this is the main factor affecting the increased appetite of the engine.
