My plumbers say i dont need one as i have thermostatic valves on my radiators but the GSE says i do. Im in a two bedroom maisonette. [FONT=arial, sans-serif][/FONT]
Discuss should i have a room thermostat with my combi boiler. in the Plumbing Jobs | The Job-board area at Plumbers Forums
Im getting confused here. The GSE came and connected me and filled in the necessary forms and said he would send them off himself.
yep will do. I just seem to be having so much trouble with my heating i wish i had stuck with my storage heaters. They only seem to work on the highest setting, anything lower and they go cold, he says its air but ive bled them and water comes out. He has told me to leave them on high for a week to get rid of the air.So expect a form through the post in a couple of days letting you know that the appliance has been registered It's important that you have this piece of paper should you ever want to sell your home on.

Not being funny but most clients or customers take a firm or trsdesmsn on trust as we do with a client or customer ?Have you checked if he`s even GSR?
I only had two storage heaters that worked so my house was always cold, now its up to 19 at the moment. What i expected to get from GSH was that if it got too warm then i would be able to turn the heating down slightly without the rads going almost cold but because i dont have a room thermostat im have to go round the house adjusting each heater, but because they all go too cold when i turn them down i then have to turn them all up again, its keeping me fit anyway. I will get used to it i suppose.It is not air.
Sounds like your house is quite warm and the valves are closing themselves down or the valve heads are badly positioned. You may be used to the house being warmer so 20Âş may feel cold.
Have a read of this which explains a bit about how they work.

Getting The Best From Your TRVs
and get them to fit a room stat.
I dont know what you mean by this, what is an interlock.your boiler requires interlock between its controls to operate efficiently and meet the building regulations.
ok thanks, i understand that now.controls to ensure that the boiler does not fire when there is no demand for heat.
so for example a trv may control a rad but has no control over the system, but a room stat and time control does.
So would i be able to control the heat i want in my house better if i had a room thermostat.ok thanks, i understand that now.

It's been inthe regs since 2002, so it must be already included in his quote
For umpteen years, good heating engineers have been fitting roomstats to control heating systems.
Each room has a design temperature. Living room 20 degrees C, hall 18, bedroom 16 and bathroom 25. Heat loss is calculated with these temperatures. Therefore a radiator fitted in the lounge will maintain lounge temperature at 20 when external temperature is at -1. It follows that a roomstat fitted in the hall and set to 18, will switch the boiler off when the hall reaches 18 degrees. By this time, the lounge will be at 20, bathroom at 25 and bedrooms at 16. Same roomstat if fitted in the lounge would be set to 20.
While a roomstat will shut a boiler down (conserving fuel), TRVs will stop taking heated water but fail to tell the boiler that it should stop. Meanwhile, the boiler has now to rely on its own stat to shut down. It keeps firing every so often to maintain the set boiler temperature.
If the TRVs are used alongside a roomstat, rooms that are naturaly warmer (say south facing), shut down by the TRV. Colder rooms continue to heat until the roomstat (hopefully fitted in one of these rooms) switches off the boiler.
If the radiators are oversized, guestimated or not balanced, the roomstat will get erroneous readings and by unable to function correctly.
Invite your engineer to carry out heat loss for the rooms and see if he is able to do that, if not choose someone else..
Modern digital roomstats can control room temerature to plus minus 0.5 degree
Ive checked the manual book that he has filled in and he has ticked the box...boiler interlock.. so does that mean he is saying that he has installed a room stat and not just the thermostatic valves on rads?your boiler requires interlock between its controls to operate efficiently and meet the building regulations. the cost of a room stat will be saved on your bill within one year, two at most. ÂŁ15 for a stat, ÂŁ5-ÂŁ10 for cable and consumables, an extra hour or so in labour time if hes competent to fit one.

Here's the Good Practice Guide :
[DLMURL]http://www.draytoncontrols.co.uk/uploadedFiles/Drayton/Industry_Regulation/Good_Practise_Guide_302_ENG.pdf[/DLMURL]
Check out the top of page 8.
n.b. don't put / remove any trvs on the radiator(s) in the same room (or hall) that the room thermostat is.
Nice guide! It's a few days old looking at the energy saving trust logo?
So if i havent got a room stat, only rad thermostats then he shouldnt of ticked the box, is that what you are sayingInstalled a stat and programmer or a programmable stat. Page 8 of the guide
They are just twist knob ones as far as i know. i dont have a room thermostat because the plumber said i didnt need but but his mate the GSE who connected me said i did but he still ticked the box knowing i didnt have one.The only paperwork he has left me is the commissioning check list.WHen he has ticked that box he is saying that it has one and it is activated.
They danger here is that this person may be lying / being fraudulent. hence the links to the guides and building regs.
If he hasn't installed a room thermostat it is almost 100% certain that he hasn't actually done anything about the boiler interlock and just ticked the box.
In which case he is in breach of the building regulations.
He should also issue with a building regulations certificate. - Have you had one?
Have you got a room thermostat?
Have you got programmable trv's with a central controller? (or are they just 'twist the top' type)
Basically yes, the GSE did soldered the gas pipes and connect me but only because i told the plumber that he couldnt do it although he said he was competent. When i got his quote he told me that he got a GSE in to do the boiler but half way though the job he changed his mind.So the boiler was installed by a non qualified engineer and signed off by another ? I would be calling gas safe!!
