Baxi 400 and smart thermostat

[Dee]

Hi

I ve had a new baxi heat only boiler installed, a Baxi 400 (+ heater sadia water tank).

I asked Baxi if I can use a smart thermostat like Nest or Hive but was told they don't work on heat only boilers....is this correct?

Not sure I would use a smart thermostat on any boiler. Smart really just means internet connectivity, generally they are just dumb on off devices.

 

If Baxi have a controller use that.

A heat only aka system boiler gets it's call for heat usually from a wiring centre and one or more motorised valves and a programmer.  There will usually be a cylinder thermostat and a programmer and possibly a room thermostat somewhere as well.  A smart thermostat would go in place of or as well as the standard programmer usually.

 

Whoever connects the smart thermostat needs to understand what controls are there and how to connect it to work with those.
