Baxi 800 Heat 

Boilers should be installed by a Gas Safe engineer and in line with specific building regulations.

Instead of turning off your boiler completely during the summer, when you likely have less need for heating, you can use Holiday Mode to ensure it works at a low level and prevent parts from seizing up later on in the year when you have greater need. You can also set your boiler to only heat your water and not your radiators.

Condensate pipes can freeze due to extremely low temperatures or ice building up on the pipe, which will need clearing in order to unction effectively. Insulating your pipe can prevent this from happening.
