Why choose the ATAG i40C combi boiler?

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 work well in homes with restricted space.

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.
