How to choose a combination boiler?

At the moment, the market segment presents two designs of units - floor and wall-mounted. The first variety needs certain manipulations - additional installation of a pump, safety equipment and an expansion tank. While wall mounted boilers are usually complete with all the necessary elements, due to which they are often referred to as boiler units.

Basic criteria:

• Heat exchanger material. The standard application involves the use of copper elements for wall-mounted combination boilers, steel and cast iron - for floor boilers. But, there are also other options. For example, copper heat exchangers can be installed in floor models and small cast iron ones in wall-mounted models. Modern models often use high-strength steel, which is not inferior to other metals in performance characteristics.
• Type of heating system. The heating system can be circulatory and gravity. 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. A circulating system differs from a gravity system in many ways, one of which is economy. In addition, it looks much more aesthetic than gravity counterparts, 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 modes. If there are several - choose a floor boiler, the operation of which in this case will be much easier. Almost all combined space heating devices are limited to the power indicator and the material of the heat exchanger, and the other criteria can be considered additional or design features.
• Power. Definitely the best choice will be the boilers with the maximum indicator. That is, the more power, the less will be the cost of heating, and, accordingly, the cost of heating. In addition, if more heat is needed and you exceed the maximum power level, the boiler will start to work in pulse mode, which is fraught with rapid wear and tear and the appearance of malfunctions. A low output level can lead to a clogged chimney, as the remaining fuel burns partially due to lack of air.

Variants of fuel used

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

• Gas and electricity. Electricity heats water most effectively, because the heating rate is considered the fastest - here provides a direct impact on the coolant with the least delay. Boilers with this combination of fuels are characterized by good variability. They provide for connection to different heating systems at the same time and several circuits can be mounted.
• Gas and wood. Gas and wood are more economical types of fuel. The dimensions of the heating device, working on such fuel, are quite large, because each type of fuel is suitable for a separate chamber. Features of the design 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 furnace chambers.
