should i have a room thermostat with my combi boiler.

[Worcester]

Nice guide! It's a few days old looking at the energy saving trust logo?

2003 though that bit hasn't been changed

Thanks guys but you havent really answered my question on the boiler interlock. When you GSE guys tick the box where it says boiler interlock provided what are you saying you have supplied or done.

Installed a stat and programmer or a programmable stat. Page 8 of the guide

An interlock is an arrangement of controls that stops the boiler firing when there is no demand for heat ie when the house has warmed up.
Std trv's only do not fulfill this requirement as they could all be shut off and the boiler will still operate heating water in a loop of pipe.
A room stat does because it shuts the boiler off until the room cools down.

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)

So if i havent got a room stat, only rad thermostats then he shouldnt of ticked the box, is that what you are saying

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.

So the boiler was installed by a non qualified engineer and signed off by another ? I would be calling gas safe!!

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.

I know ive done wrong so dont all have a go at me please, i dont have any backup so thats why im asking you guys for all the info because if i try and question my plumber he just makes me look a fool. The problem is ive known him and his entire family for years.

You now know what your system should have and how it should be configured.

Tell the plumber that you need it done in accordance with the building regs.

If between then they wont, then report to Gas Safe, Building Control, and your local Citizens Advice Bureau, as they shouldn't be allowed to continue this bad practice.

Just dowload the document on this link TACMA launches its guide to the new 2010 Part L Regulations - BEAMA | News
print it out and show it to them....

He will charge me for the room stat because it wasnt in the quote, i just thought that i was getting everything that was needed. I rang the guy who connected the gas today and asked him why he had ticked the box that said boiler interlock provided, he said that its nothing to do with having a room stat and that it just means that you can turn the boiler off manually.

Is it all working properly now?

That's a new one on me!

No, the rads sound like they have got air in them, they are hissing but when i bleed them no air comes out. Its a very annoying noise.

He does doesnt he. Im female and know very little about heating but i think i know a bit more than him.

As I said before

Your benchmark will be filled out (hopefully) and there is a requirement to provide interlock. A room stat is the simplest and most common way of doing this. I would be questioning whether you have chosen the right installer for the job if they do not recognise this requirement regardless of personal opinion. If we could pick and choose what reg's to abide by then it would make the job a lot easier but ..... Unregulated?

If I was you I would concentrate on getting everything working first. I think you should ask the fitter to come back and look at the noise/air issue.

A simple explanation ?
Boiler interlock is not a physical device but an arrangement of the system controls (room thermostats, programmable room thermostats, cylinder thermostats, programmers and time switches) so as to ensure that the boiler does not fire when there is no demand for heat. In a system with a combi boiler it can be achieved by fitting a room thermostat.
In a system with a regular boiler it can be achieved by correct wiring interconnection of the room thermostat, cylinder thermostat, and motorised valve(s). It may also be achieved by more advanced controls, such as a boiler energy manager. TRVs alone are not sufficient for boiler interlock

i have questioned whether i did get the right installer but its a bit late now. I thought they were competent, how was i meant to know. The benchmark has been filled out as i said but he has ticked the box that says boiler interlock provided and as i said above he said its nothing to do with a room stat.

This is what i read and tried to explain to him but he wont listen.

Then get rid of him. Cut your losses on it and get a professional in. I've followed your posts and I'm abit concerned about your install. Can you post pictures of the boiler install?

so am i worried. I dont want him to do anything to my heating anymore. I know i should cut my losses but im very angry for the situation he has put me in because i know his family well but i dont want to involve them as its not their problem.
I will post some pics, what exactly do you need to see.

 

[Rickster123]

I'd like to see the boiler, the flue, the pipework to the boiler and the gas meter please if poss.
