I already purchased the Google Nest Thermostat, will you install for me?

Our supply and installation fixed fee is provided on the basis that we supply and fit and within the M25 zone where we service.  If you have already purchased the Nest thermostat we can also do just an installation starting from £100 within this same zone. Please contact us for a more information.

Is the Thermostat Battery or Mains Powered?

Both the 3rd Gen Learning Thermostat and Nest Thermostat E are Mains
The 3rd Gen Learning Thermostat can be wall mounted taking the power from
the Heat Link T1 & T2 Terminals or on a stand (additional purchase) taking
power from a 12volt plug socket
The Nest Thermostat E is powered by a 3 pin plug only on a stand, which is

Can it control underfloor heating?

Yes it can. The Thermostat works like an on/off switch. It will therefore be
wired to the zone valve for that underfloor heating zone, possibly via the
wiring centre or manifold. Again, the more underfloor heating zones the
customer has, the more Thermostats they may need

Can the Thermostat be controlled by Alexa?

Yes but only the 3rd Generation Learning Thermostat, not Thermostat E

Can the colours be changed on the Thermostat bezel?

No but it comes in four different colours so the customer can choose their

How do you master reset the Thermostat if having connection issue?

You can do this on the Thermostat in the settings OR by holding the Heat Link
button down for 30 seconds to do a complete factory reset.. If fully factory
resetting the Heat Link we also recommend to fully factory reset the display so
that both can create the communication protocol again. Keep in mind that this
will delete all settings and options on the display

What type of boilers do Nest Thermostats work with?

In short, they work with the majority of boilers, combi and system, open therm,
air and ground source heat pumps, biomass, hydronic underfloor systems. You
can also find our compatibility checker on our website if unsure

Are both Thermostats Boiler Plus compliant?


Do Nest have thermostatic radiator valves?

No not at present but we work with other brands that do. These can be found
and added via the Google Home app.

My heating is coming on very early in the morning?

This is a feature called True Radiant. The Thermostat has learnt how long your
heating system will take to preheat in the morning to reach the target
temperature. This can be turned off or adjusted accordingly in your app in the
Thermostat settings
