iR Regular Boiler

i15R i18R i24R i32R i40R

Every ATAG boiler carries a 12 years warranty as standard with options up to 18 years and they’re professionally installed by our ATAG Selected Partners.

Also known as conventional boilers that are fitted in many UK homes. Regular boilers offer a simple and straightforward boiler replacement solution that traditionally requires a loft space to house the feed and expansion tank.

Extremely energy efficient with simple to use controls. Extensive flue solutions mean you can site the boiler almost anywhere in your home.

Homeowners seeking even more efficiency can combine an iR Regular boiler with one of our iSteel hot water cylinders.
