Question about opentherm

[Husk24]

hi guys

Im thinking of buying a nest thermostat. I am aware my boiler is opentherm compatible. Im particularly interested in the way the boiler runs using opentherm. After installing this thermostat I decide do not like the way opentherm works, would it be easy as switching opentherm off from the nest settings or will it be wired in a way I would have to get it re-wired/changed?

Is is more efficient cheaper to run it via opentherm?

Depends on your house and how warm you like it. (It is more complicated than that, but very long winded)

It's designed to interlink as an open therm device. It baffles me as to why anyone would want to do anything different. You will have a huge scope of settings to tailor the outputs and timings to pretty much any of your requirements.

I guess the option to use ‘true radiant settings’ on the nest would be just as good.

@gingalig

So you would definitely recommend opentherm?

No I would recommend ebus. But your boiler probably doesn’t support it if it has opentherm.

Your installer will look very confused if you try and suggest anything different, and would probably charge considerably more if they agreed to do it. If you really want more control or savings maybe consider evo home or drayton wiser. Nests are good though and very user friendly.
