There are a few odd types of condensing boilers available on the market nowadays… Conventional or system boilers function by heating water contained in a tank or cylinder, and this option happens to be ideal for much larger dwellings with several bathrooms or when the pressure of mains happens to be low.
The other category is the combi boiler which doesn’t truly require a water tank or cylinder as it heats water entirely from the mains. This is the most suitable option for smaller dwellings as it is a compact, space-efficient option that can fit into any room for the most part. Condensing combi boilers are a category of HVAC appliance that includes a special heat exchanger that also works as a condenser. They are able to achieve greater efficiency levels since they capture more heat from exhaust gases. They have a fairly large heat exchange surface that allows them to move as much heat as possible from your boiler’s burner into usable heat, thus allowing less heat to get away. Due to this, condensing combi boilers are sincerely the most energy-efficient HVAC solution on the market. This operating mode also diminishes nitrogen oxide and carbon emissions, making them an eco-friendly solution. There are a few different types of condensing combi boilers, however they all task the same way generally speaking. When the temperature level goes down, your thermostat will signal your boiler to become active, and the heat will then be transferred to your central heating appliance. Once the required temperature has been reached, your thermostat reacts again to turn your condensing combi boiler to the off position. The benefits of a condensing combi boiler are numerous.
