Why buy the i28C combi?

The ATAG i28C is the mid sized combi boiler in the range. They also have outputs of ATAG i36c 36kW and ATAG i40C40kW, respectively. The ATAG i24C can be used in homes that have a lower demand.

Because of their efficiency and compact size, combi boilers are common in UK homes. Combi boilers do not require additional hot or cold water tanks as would a regular boiler or system. Combi boilers can be space-saving, but they have a limit on the amount of hot water they can provide.

ATAG iC combi boilers are 94% efficient, which could help you to save money on your energy bills. You can also pair the ATAG iC combi-boilers with an ATAG ONEZone smart control, which will increase the efficiency by an A to A+ for central heating as well as hot water.
