Baxi 600 36kW
The Baxi 600 Combi 36kW is the middle of Baxi's combi range, with a longer warranty than the 400. It's compact enough for a standard kitchen cupboard and delivers hot water at up to 15 litres a minute.
It has a stainless steel heat exchanger and brass hydraulics, and the EasyFill link lets you top up your system pressure without calling an engineer. A pre-heated condensate trap helps prevent frozen condensate pipes in winter, and it works with the Baxi uSense smart thermostat.
Backed by a 7-year Baxi parts and labour warranty.
