room stat

Hi :) Since about midday today we've been experiencing a very odd problem with our boiler (Main Combi 24 HE). Got in earlier to find the place sweltering, with the radiators red hot and the room temp showing at about 27C. We have a Salus RT300RF room stat and this was set to 15C - but the...

Hi, I'm looking to install a wireless programmer and stat on my Main Combi 30 HE. I believe the Towerstat RF/BM Radio Frequency Control Receiver is compatible and the modular receiver simply replaces the existing mechanical timer. However, what happens to the existing room stat? Will I...

im a my wits end with this one. mainly on hot water and sometimes on heating the boiler faults on f 1. i'v got 28mm gas all the way to the boiler and i have shortened the flue. on full demand the boiler still either fails to light or cuts out when in heating mode. i called glow worm in to have a...

I have an oil, floor standing boiler.I have my CH on all day from 6am till 9pm, this is controlled by the room stat(temp control only). I then have to run the boiler flat out for 2 or 3 hours in the morning to again reach temp. My question is, would it be more efficient to leave the boiler on...

I'm replacing a traditional mechanical heating/hot water timeswitch with a Siemens REV24RF. The old timeswitch has traitional wiring NL1234 with NL and 34 wired. The Siemens has N L Lx L1 L2. How does the wiring map across ? I've got a suspicion I may have got the wrong model because...

As a result of a unfortunate accident on the roof, (please don't ask) we are replacing our Ideal Isar HE 30 with a Broag Remeha Avanta 28C, after an awful lot of research. To be honest the Ideal has in fact been far from "ideal", having had a new PCB, three igniters and User control board...

Hello, I have been to look at a system where the boiler seems to be ignoring the room stat,and going on getting hotter and hotter.Eventually the customer says she hears a strange noise from the boiler,maybe similar to a kettle boiling. Does this sound as simple as a faulty room stat (honeywell)...

Evening all. I've been working at a customer's place and she asked me today why her upstairs radiators are really hot but the downstairs ones are only medium hot. I'm not entirely sure myself. The only thing I can think is that it's somehow down to the lack of TRVs on the system. There's a room...

Any idea what these boilers are like? are they any good. My friend has just had one fitted and they look good. She also has a remote control to operate the boiler and this is also the thermostat. Sounds pretty funky. Opinions would be appreciated good or bad as we are thinking of getting...

A client has a back boiler fitted about 6 years ago (British gas). All is good but the room thermostat is set at 15 degrees and keeps shutting down. The thermostat has a plus and minus button on it and that is it with a digital display showing the temperature. Each time you plus the heat it goes...

Hi folks, I've got a Grundfoss CH pump not working. I've taken the silver end cap off and spun it with a screwdriver but still no go. I don't think I've got any motorized valves as its an old system with 2 flow pipes for hot water and CH and 2 returns. Satchwell room 'stat clicks when you turn...

I'm 99% I got the correct model and I'll double check when im home but its definately an Ideal Isar and from what I've seen here so far its confirmed what I already knew and that there a pile of... you know what. We have only been moved in for 3 years but have had Ideal out twice at £240 a...

I had a megaflow relocated to the loft, which all seemed fine after testing. I now find that the boiler/megaflow are not responding to the commands from either the thermostat or timer. I have resorted to turning the boiler on and off manually in the morning and evening. So the mechanics of the...

Hi everyone, I rent a flat with an old boiler which doesn't have a timer function - so I have to manually switch the heating on and off in the mornings and evenings. Very annoying. The landlord won't pay to install a timer so I'm trying to design something that can turn the control knob...
