ATAG i40R 40kW Regular Boiler
The ATAG i40R is a highly reliable and robust regular gas boiler.
The i40R has an efficiency rating of 94% and an ErP A rating, which means it can reduce your energy bills.
The ATAG i40R is the most powerful regular boiler in the ATAG i range, with an output of 38.8kW for central heating. The boiler’s size makes it ideal for homes with up to 20 radiators and 1-2 bathrooms.
When buying a new or replacement regular gas boiler, it is important to remember that you will need to have a hot water storage cylinder, a cold water tank, and an expansion tank fitted alongside your heating system.
For this reason, regular boilers are not recommended for homes with limited space. The ATAG i range is also available as a combi boiler for homes with little space.
