Thermostat Locations

Hey all

Not sure if this is the right place to post this.

We have just moved into a 3 storey house where we have 2 thermostats, 1 on the bottom floor controlling radiators on the bottom floor and 1 on the middle floor controlling the radiators on the middle and top floor.

The only issue I have is they have put the middle floor thermostat in the smallest bedroom meaning that this heats up quicker than the rest of the middle and top floor, Especially as our top floor bedroom is 7 x 5 metres in size.

Would you say that this is the correct place to put this???

I was looking at the nest system but getting confused with it. The way I see it is that you have a wireless thermostat which speaks to a unit that is put in place of the thermostat in the middle bedroom, this would mean I could move the thermostat to the top floor and control the middle and top floor from the temperature of the top floor.

Hope that all makes sense, any suggestions would be great

What has been configured is a very crude attempt at zoning which, at best, is a fudge. I do not know how you would use Nest in this situation; however, I can see 2 alternatives. One, replace both thermostats with smart devices which you can move around the two floors. Two, look at zoning systems such as Evohome or Heat Genius which allow you to set up to 12 different zones controlled from one central controller.

The latter are not cheap but they do allow the user to set times/temp targets for each zone. We have a large house with 12 zones. Most of the time rooms not in use are kept at a minimal temperature and the heat follows us around the house.

We are probably saving 15 to 20% on our gas bill but the real benefit is that we have never been more comfortable.

Hi

thanks for the quick reply. Do you know where I can get an idea of price for the evohome or heat genius system.

We have a three storey house that has 3 bedrooms 3 bathrooms kitchen living room and 2 stairs and landing. Im willing to do anything at the moment to sort the dam heating system out they have installed

Try this link:

The basic system is a controller with remote access if you require it. You DO NOT need HR92 TRVs for all rooms. For example, if you have guest rooms that you rarely use then stick with the standard TRV turned down. We also have the £90 hot water kit as we have an unvented tank which controls the tank temp in a set range.

A couple of things:

1. Do not believe the headline savings figure of 40%: this figure is based on a test 3 bedroom home in a chamber with no heating controls as the baseline.

2. Boiler relays (the things that control the actuators/boiler) need to be sited very carefully; ie, not within 30cms of any metal, electrical fittings etc. the same applies to Hive and Nest.

3. Choose your installer very carefully. There is a lot of good advice about Evohome and Heat Genius on:

Hi

Thanks.

So my combi boiler has a heating control for the heating water on the boiler, will I need a relay??

Also how do I go from the wired system to a wireless system. I mean do I have to attach something to the boiler to switch it on and off or is this what the relay is for?

I suggest that you post details of your CH/HW system on the Automated Home website and someone who knows will give you the advice that you need.

This might also give you a few hints:
