A combi-boiler, or combination boiler, combines the functions of a central heating boiler and a water heater. It heats water for both space heating and domestic hot water supply.

Combi-boilers offer space-saving benefits, as they eliminate the need for a separate water heater. They provide hot water on demand, reducing energy consumption and improving efficiency.

Yes, combi-boilers can be used for radiant floor heating systems. They efficiently heat water and distribute it through the floor, providing comfortable and energy-efficient heating.

The installation time depends on factors like the complexity of the system and the existing infrastructure. On average, combi-boiler installations can take a day or two.

Combi-boilers are suitable for smaller to medium-sized homes with moderate hot water demand. For larger homes, a system with higher capacity may be recommended.
