No room termostat for my baxi boiler

lar316

Hi all, i am wanting to save money on my energy bills like everyone else. I have read that turning down your room thermostat will help with this. Trouble is, i haven't got a room thermostat. The only controls i have are on the boiler itself. I have a Baxi instant 80 HE boiler. It was installed back in 2006. Does anyone know how to fit a room thermostat to this boiler? Can i fit a wireless thermostat to this as i've recently decorated my hall stairs and landing so running cables are not really an option? If i can, can anyone recommend one, and how do i fit it? I have TRV radiator valves fitted to most of my radiators, how do they work? how do i use them?

I know there is a lot of questions but i'm totally bamboozled by all of this. Many thanks in advance.

If you have TRV's, you effectively have thermostats in each room, so why would you want another one fitting! See here for more info.

I would get a plumber (heating engineer) out if you really don't have any thermostat its a job for the professionals to fit one.

The TRV's control each rad they normally have scale 1 to 5, 5 being hottest they are a bit vague but for rooms I live in I have mine on 3 and for rooms I just pass through I have them on 1 (these rads hardly ever come on). The thing about TRV's (and a room thermostat for hat matter) is they control at what temp the rad is on and off not what temp the rad actually runs at that is controlled by the boiler.

I fitted a wireless room thermostat to my Worscester boiler in about 15 minutes. Essentially there were four connections to make to the wireless receiver which I mounted under the boiler - the live and neutral for power (just hooked into the same FCU as the boiler was using), and then there were two connections to the boiler itself, which are what the receiver connects and disconnects to tell the boiler to come on and off.

As l long as you're competent with electrics, I wouldn't say it was a job for a pro.

Here's the instructions for your boiler: http://www.baxi.co.uk/docs/Baxi_Combi_Instant_HE_Installation_and_Servicing_Instructions.pdf. See page 25, fig 29. I used two lengths of standard white lighting flex for mine, one for the power the other for the switch connection.

Make sure you locate the wireless control panel in the coldest room in the house, away from the radiator. Ensure the TRV on that one radiator is set to full on - the wireless panel will replace its job in that room.

I went with the predecessor to this thermostat.

i had individual thermostats on every radiator when i first moved in.

i dont know what was going on but the thermostats seemed faulty to me. at night they would turn themselves off and not come on even when the rooms where freezing cold unless i slightly turned the valve either way. so i got rid of them.

does anyone know what was going on?

This is incorrect and will waste the OP a considerable amount of money. Search google for part 'L' regulations.

It is not incorrect. A room thermostat should not be used in the same room as TRV's.

I don't think that part L will help the OP, who obviously doesn't know how to effectively use their three year old heating system, so how does your post help?

I'm certainly not interested in part L.

I am interested in answering the OP's question and giving the right advice. I have no idea what your motives are, but your reply was incorrect, contrary to best practice and was illegal at the time of the OP's boiler installation.

I don't care what you are or are not interested in, common sense should tell you not to advise someone on something that you know nothing about.

You haven't given the OP any advice!

Because others had already given the correct advice, which I hope they take heed of and ignore the nonsense you wrote.

Do you have the slightest idea of why you are so completely wrong BTW, or do you have no interest in that either?

Personally I take most advice given by money making tradesmen with a pinch of salt. Every property is different and you know nothing about the OP's property or even where the live.

Illegal.
