How It Works
The Combi Boiler provides domestic hot water and space heating in two separate loops.
What is a Combination Boiler?
Combination, or Combi, boilers provide high efficiency space heating and domestic hot water (DHW) in a compact footprint that is easy to install and maintain. When a hot water tap is opened, incoming water flows through the heat exchanger. Heated boiler water, supplied from the fire tube heat exchanger, prioritizes heating the domestic water to the desired temperature. When space heating is needed, a diverter valve directs the heated boiler water into the external space heating loop.
What are the main advantages of a combi boiler?
Combi boilers combine space heating and hot water supply in one high-efficiency appliance, providing a space-saving choice. Combi Boiler boasts industry-leading hot water delivery and up to 74% more space heating capacity than other combi boilers, ensuring that you are always comfortable. They are also easy to install and operate.
What is the difference between a combi boiler and a traditional boiler?
Although both can heat your home and provide hot water, there are key differences. Traditional boilers are designed mainly for space heating. Hot water from the boiler is circulated through radiators or a hydronic heating system to warm the ambient air. The traditional boiler water may also be used for domestic hot water by directing the water through a separate, integrated water heating unit before routing it to a fixture, such as a faucet or shower. Some traditional boilers are compatible with potable water, but others require additional water treatment.
Combi boilers are designed to accomplish both space and water heating with a single appliance. Like a tankless water heater, a combi boiler provides hot water on demand. It can also seamlessly switch between water heating and space heating to provide the best possible experience.
Does a combi boiler save money?
Combi boilers are highly efficient for both space and water heating, and they may contribute to lower energy costs in your home.
Are combi boilers energy efficient?
Yes! They are ENERGY STAR® certified and have a 95% AFUE rating. Because combi boilers provide both space and water heating, it is like having two high-efficiency appliances in one. Combi Boiler also has a modulating combustion system with 10:1 turndown to ensure high-efficiency operation even when heating demands are reduced.
