Radio thermostat?

[The Natural Philosopher]

mm. I want to improve control on my UFH and given that its all zoned anyway, add a radio thermostat to a large space, and a couple of motorized actuators for the existing polyplumb zone valves..oil prices make it a sensible economic proposition.

Currently its all fed off a timer and a thermostat in exactly the wrong place - in the kitchen where the Aga is.

The plan is to hook the existing thermostat up to a couple of actuators to kill heat to the kitchen UFH except in direst winter conditions, and use an overall stat in the largest places that the UFH currently heats - the living/dining room area.

The other zones can remain unregulated -they are small and unimportant and don't lose a lot of heat.

What would be nice is an UNTIMED thermostat - don;t need to replicate the timer - but with a bit of 'feed forward' that can anticipate the slow changes you get with UFH.

Anyone know of such - has to be radio - no chance of cabling it whatsoever without huge disruption.

Have a look at

and use a search word of 'radio'

They have a range of different RF thermostats and receivers including a multiple channel receiver to support multiple room thermostats. Some of those have timers but those can be disabled if you want.

I sent all morning looking at pictures, and in the end the only one that looked small and neat was the Sunvic one. Its just a 'remote thermostat' ...bloody heck By the time I had got that and a couple of actuators for the Polyplumb, it was three months of heating oil. Better be worth it!

Out of interest, is there such a thing as a motorized valve that switches between two paths only? I could maybe use that in my fan blown stuff...instead of having the thermostat switch the fan alone, divert the hot water past it as well..

I have the Sunvic "programmable"

It does have a clock but you can ignore that and just use it as a thermostat, like I am now. It is sitting by the PC, warming the room up.

Mine came from B&Q for £50 last spring.
