How to choose a combined boiler?

At the moment, the market segment represents two designs of units - floor and wall. The first variety needs certain manipulations - additional installation of a pump, safety equipment and an expansion tank. While wall-mounted boilers are usually equipped with all the necessary elements, which is why they are often called boiler units.

Main criteria:

• Heat exchanger material. Standard use includes copper elements for wall-mounted combi boilers, steel and cast iron for floor-standing combi boilers. But, there are other options. For example, copper heat exchangers can be installed in floor models, and small cast iron ones in wall models. In modern models, high-strength steel is often used, which is not inferior to other metals in performance.
• Type of heating system. The heating system is circulating and gravitational. If it is important for you to buy a boiler without electricity and with a gravity heating system, then wall-mounted devices are not suitable. The circulation system differs from the gravitational one in many ways, one of which is efficiency.In addition, it looks much more aesthetically pleasing than gravity analogs, and its gas consumption is 10-15% less.
• The complexity of the heating system. Here it is worth focusing on the number of heating circuits and temperature conditions. If there are several of them, choose a floor boiler, the operation of which in this case will be much easier. Almost all combined space heating devices are limited by the power rating and heat exchanger material, and the remaining criteria can be considered additional or design features.
• Power. Definitely the best choice would be boilers with a maximum rate. That is, the greater the power, the lower the heating costs, and, accordingly, the heating costs. In addition, if more heat is needed and you exceed the maximum permissible power level, the boiler will start to operate in a pulsed mode, which is fraught with rapid wear and malfunctions. A low power level can lead to clogging of the chimney, since the remaining fuel is burned partly due to lack of air.

Fuel Options

There are varieties of combined boilers that use two or more types of fuel. But, two options are most common - gas can be combined with electricity or with firewood.

• Gas and electricity. Electricity heats water most effectively, since the heating rate is considered the fastest - it provides for a direct effect on the coolant with the least delay. Boilers with this combination of fuels are characterized by good variability. They provide connection to different heating systems at the same time and you can mount several circuits.
• Gas and firewood. More economical types of fuel are gas and firewood. The dimensions of the heating device operating on such fuel are quite large, since each type of fuel is suitable for a separate chamber. The design features of boilers with a combination of gas and wood determine the placement of one or two heat exchangers, where for the first case it is a common element for all available combustion chambers.
