Advice on digital thermostats.

elsmandino

Hi there,

I have got an electronic programmer next to my hot water tank that controls when the hot water and heating come on (5/2 type).

I also have a mechanical thermostat in my hallway, which is on its last legs and now has to be replaced.

The obvious thing to do would be to replace my thermostat with a digital one, but on further expection, it seems that you can get programmable ones.

What I can't get my head around is how a programmable thermostat would work in conjunction with my existing programmer.

Do I remove the existing programmer itself and use only the new thermostat or do I leave the existing programmer heating on all the time and let the thermostat turn the heating off and on?

Let me know if you need any clarification.

Thanks

A

You can have the 2 working together

I have done it in my house which I rent out now. Problem is I constantly worry about the tenants mental ability to follow instructions that the boiler programmer must always be set permanently on for heat

Leave the existing programmer heating on all the time and let the thermostat turn the heating off and on. Set it to around 14/15 degrees overnight and it won't kick in unless there's a really cold snap. Another advantage is that you can set some of them to be say 15 degrees while you're away on holiday and then warm up the house for when you get back.
