hi what is the best thermostat to use with this boiler?

Asked by: esm70
Good Afternoon Esm70, if you would like to a SMART thermostat which means you can also control your heating from an app on your phone, the best thermostat would be the Baxi Usense, which is Screwfix SKU 230FR. If you are happy with just a 'normal' programmer and thermostat we would recommend the Baxi single channel wired programmable room thermostat which is Baxi sales code:7212438. Kind Regards Paul at Baxi

What is the distance from the base of the boiler to the centre of the flue

Asked by: Leccy7
Good Afternoon Lecc7, the height of the boiler is 700mm (top to bottom) and the flue is 100mm in diameter. You also need 200mm bottom clearance from the base of the boiler and 178mm top clearance from the top of the boiler. Kind Regards Paul at Baxi

Can the flue be changed to a rear flue

Asked by: Ralfie
Good Afternoon Ralfie, The flue connection is at the top of the boiler which can rotate 360 degrees which gives you the option of a side flue or back flue. There is no flue connection for it to come out the back of the boiler only from the top. Kind Regards Peter at Baxi
