Nest thermostat with two boilers

[ikaashchatha]

Hi

I have a house with two central heating systems (two boilers). One warms up the left side of the house (radiators only) and one warms up the right hand side of the house (radiators and underfloor heating). I want a smart system that works for all of this.

Is it possible for me to have one thermostat for the left side which controls the temperature there, one on the right hand side downstairs to control the underfloor heating and then one upstairs on the right hand side to control the radiator and temperatures. I think I would need three. Is it possibly to have all three sitting on one app and one login? 

I don't want to have two logins (one for left side and one for right side).

Thanks

Hello Ikaash,

Thanks for reaching out to the Google Nest Community Forum.

Depending on your said systems, if they are both operated or installed to be programmed by a single thermostat, and if they are Nest-compatible, The Nest Thermostat is not compatible with two different heating systems, unless these are Heat pumps with separate heating units. But I'd be happy to take a look at this for you.

Could you please share with us a photo of your thermostat's wiring setup and your boiler's make and model?

I'll look forward to your response.

Regards,
Mark
