How to choose a floor standing gas boiler?

From this article you will learn how to choose a floor standing gas boiler. You have to remember that for 2021-2022, floor standing gas boilers for private homes are still a more powerful way to heat a room, as well as being reliable and durable compared to most of their counterparts.

Criteria worthy of consideration:

• Thermal capacity. On average, 1 kW of appliance power can heat about 8 m2. Calculate the total area you need to heat and divide by 8, then you get the required number. Add another 1 kW for heating water. Do not forget about the additional parameters in the calculation: the thickness of the walls, their material, the number and quality of windows and doors, the presence of the attic, etc.
• Number of loops. Gas floor boilers can be single-circuit and double-circuit. One-circuit only heats the room, and the two-circuit in addition to this heats the water. The cost of double-circuit models will be only 10-15 percent higher.
• The material of the heat exchanger. Cast iron models are not susceptible to acid attack and thermal shock. Steel heat exchanger is light and strong, not prone to cracking, resists deformation. Models made of copper are rare because of the high cost. Differ in thermal conductivity, resistance to corrosion.
• Type of combustion chamber. Can be open closed. In boilers with an open chamber, the air will be taken from the room where the boiler stands, so there should be a chimney where it is located.
• Principle of operation. Convection boilers are ordinary devices that accumulate heat energy by burning gas in the combustion chamber. Some of the heat is lost in the process. Condensing type - more expensive and advanced, with an additional heat exchanger, which accumulates the heat of the condensate from the exhaust gases. The temperature of the latter is very low, and the energy accumulated by the additional heat exchanger is used to heat the return line.
• Managing. There are two options: manual and automatic. Automatic is safer, does not require constant monitoring by the owner, however, such a model will also be more expensive.

The best floor standing gas boilers by price/quality for 2021-2022

Protherm Bear 20 KLOM

Protherm Bear 20 KLOM is a gas single circuit boiler of the automatic type. It is necessary to install it in accordance with all the indents from the nearby walls. In the conditions of domestic networks device shows itself well and gives an efficiency up to 92%, which is an indicator of an excellent level. Heat is generated from the combustion of gas, because it is a convection-type device.

The heat exchanger here is cast iron, durable, but heavy and inert (takes a long time to cool down and a long time to heat up). The auto ignition ignites the burner and turns it off using a certain algorithm, so that the fuel will be significantly saved. This is also facilitated by the modulation of the flame burner. The control of the model is electronic, which does not require your constant supervision, but is dependent on power surges (in case of strong drops it can turn off).

There is a thermometer and pressure gauge to monitor the indicators inside the boiler. Among the protections are gas-control, which stops the gas supply when the flame goes out, automatic activation at abnormally low temperatures to warm up the unit, and an independent shutdown if it reaches too high temperatures when heated.

Specifications:

• type of heating boiler: gas, convection;
• thermal capacity: 12-17 kW;
• heating load: 13.50 - 19 kW;
• Control: electronic;
• The material of the primary heat exchanger: cast iron.

2. Lemax Premium-30B.

Lemax Premium-30B - this is a two-circuit gas boiler, which should be installed on the floor with observance of the distance to the walls. Heat is produced by burning gas, the efficiency of the unit is not bad, up to 90% in conditions of domestic networks. The advantage of this model is that it does not need a power grid, the inclusion is carried out manually, and the coolant circulates without a pump.

A small disadvantage is the uneconomical operation of the boiler. The device is controlled manually, it has few parameters, it also guarantees a cheaper repair and greater reliability compared to most automatic counterparts. The thermometer will show the temperature and to avoid overheating the boiler will shut down when the water gets too hot. The safety system switches off the gas supply if the burner flame goes out.

The heat exchanger is made of steel - it is a lightweight and shock-resistant material, the cost of which is low. However, there are also disadvantages: greater susceptibility to corrosion and shorter life than other materials.

Heat is generated from the combustion of fuel, the boiler works on both natural and liquefied gas. Switching on is done manually, there is no opportunity to spend less gas during operation, but the reliability is much higher than that of automatic counterparts.

Another plus is a more budget-friendly repair because of the lack of electronics and a small number of control parameters. There is a thermometer to monitor the temperature of the coolant. Of the protections is an air vent, which discharges some air when the pressure in the heating system. Gas control automatically stops the gas supply when the flame goes out. The heating medium circulates without a pump. The combustion chamber is open, so it is better to install the device in a special boiler room with good smoke removal.

The heat exchanger is made of reliable and durable cast iron, resistant to corrosion. But it is worth noting that it does not tolerate sharp temperature changes very well, and also takes a long time to gain temperature and does not cool down for a long time. The weight of cast iron is also large compared to other materials.

Auto ignition switches the burner on and off, which saves fuel. The flame modulation allows a gradual adjustment and also helps to save gas.
