Baxi 615 15kW Gas System 2 Boiler – 7798687

The Baxi 600 System Boiler is ideal for homes with higher hot water demand or multiple bathrooms. At only 290 mm deep, it fits neatly inside a standard kitchen cupboard and features integrated pipework within the casing for a tidy, space-saving installation.

For added convenience, it is fully compatible with the Baxi uSense smart heating control, enabling homeowners to manage heating and hot water directly from a smartphone or tablet. The Baxi 600 runs on natural gas or LPG without the need for a conversion kit and is hydrogen-ready (up to 20%), making it a future-proof solution. When paired with a hot water cylinder—such as the Megaflo Eco or a Baxi cylinder—it delivers additional hot water capacity.

Designed for year-round reliability, it includes a pre-heated siphonic condensate trap to help prevent freezing in colder weather. For peace of mind, the boiler is backed by a warranty of up to 7 years (subject to Baxi’s terms and conditions).
