What is a condensing combi boiler?

There are two different types of condensing boilers available on the market today.

Conventional or system boilers work by heating water contained in a tank or cylinder. This option is ideal for larger households with multiple bathrooms or when the pressure of mains is low. The second type is the combi boiler which doesn’t require a water tank or cylinder as it heats water directly from the mains. This is the best option for smaller houses as it is a compact, space-efficient option that can fit into any room. Condensing combi boilers are a type of HVAC system that includes a special heat exchanger that also acts as a condenser. They are capable of achieving greater efficiency levels since they capture more heat from exhaust gases. They have a large heat exchange surface that allows them to transfer as much heat as possible from your boiler’s burner into usable heat, thus allowing less heat to escape. Due to this, condensing combi boilers are currently the most energy-efficient HVAC solution on the market. This operating mode also reduces nitrogen oxide and carbon emissions, making them an eco-friendly choice. There are different variations of condensing combi boilers, but they all work the same way. When the temperature level falls, your thermostat will signal your boiler to activate, and the heat will then be transferred to your central heating system. Once the required temperature has been achieved, your thermostat reacts again to turn your condensing combi boiler off. The benefits of a condensing combi boiler are extensive.
