Central heating but no thermostat

ruggedtoast

After putting the heating on in our house for the first time since we bought it in April, we discovered after much searching, that there is no wall thermostat.

Each radiator has something I now discover is called a thermostatic radiator valve, which controls the heat in each room, but nothing to actually shut down the overall system apart from the boiler hitting its set temp.

Should we necessarily be bothered about this and how much would it cost to install the cheapest thermostat possible (not wireless or anything).

There is a decent digital timer controlling the CH and HW so I dont really want to mess about with that.

Nothing to worry about

You don't need a "central" thermostat. Just adjust the individual thermostats to get the required temperature in each room.

Much more accurate than trying to control the temperature of your cold, draughty lounge with the thermostat situated in a nice warm hallway !

There should be a bypass so that if all the valves are shut the pump isn't trying to pump water through all these valves - OR - just leave one valve fully open (to make sure), bathroom?

We didn't have any wall/room thermostat in our house either, and after 20 minutes of messing around with the cables, following wiring diagrams, and testing the system, I was able to add the wireless room stat that I purchased in B&Q. Though most good hardware shops sell them, they come in all shapes, sizes, prices - I was just lucky that they had a discontinued one for a fiver. Yes, a wireless room stat for a fiver!!!

Anyway, it's been great, and has in the past week alone saved us nearly 10 gas units a day (40p/day saving). If it carries on like this, I really won't complain.

Oh, and the main advantage of having the room thermostat is that it cuts out the boiler completely when the house/room hits the required temperature. The room where the stat is needs to have the radiator on max, otherwise it may never kick in. But when it does, the boiler is off, the pump doesn't work, and it saves on the electricty for the pump not working (and consequential wear and tear).

So yes, go buy one, if you're not confident then get someone in to wire it in. They should pay for themselves in no time at all...

I disagree. A central thermostat is a must.

I have had the individual rooms radiator thermostats before and you end up having to control the boiler manually.

Get a wireless thermostat installed. I bought a Honeywell one of Ebay for £40 and spent £50 on getting it fitted. Well worth the money.

Use heating/DHW controls to optimize your system and reduce energy costs....more here.

Get a Honeywell CM927.

The easiest to use and most reliable. Get it professionally fitted. Around £200.

personally i would fit i wired one if able

i use honeywell mainly the ( removeable wire linking two contacts ) on your boiler
should be wired into contacts 1 and 3 on the honeywell wired stat
i use 4 core cable and wire earth and neutral in also contact 2
which energises the accelerator in the roomstat and saves
money accelerators allow a 4 degree differential in the roomstat which avoids cycling ( boiler turning off then on when a 1 degree (c) drop is sensed ) the accelerator in the roomstat which requires a neutral makes this part of the roomstat, become more than just a thermostatic switch,it saves money, and the fourth earth conection speaks for itself ............happy hunting have a nice weekend karl..........

Does not compute.
