Upgraded central heating system

[frankm]

Hello
I need some advice please,i am not a plumbing engineer just a consumer
I have just had my old system boiler(25 yearsold) replaced with a combi boiler Ramaha 28C and all rads replaced with trv's (well apart from 2 rads one in hallway and the one in the bathroom) the engineer said thats how they do it ,leave two trv's off.
my question is my old system had a room stat in hall but this has been disconnected from the system and we have no room stat now as the engineer said that the trv's do the job now, but reading i see that you have to have a room stat due to building regs.

Who is correct and should i get back on to the engineer to get a room stat fitted or does my boiler not need one( i read some dont as the have a flowswitch or something or am i getting confused)

The only control is the timer clock on boiler itself

Please any advice

Thanks in advance

The room stat should be in the hall and the bathroom should have a trv on aswel

Get him to wire the stat into the new boiler. It should have one.

frank did you see his gas safe ID card ? and check the back ?

 

[gaspastemania]

building control i am affiad so needs one plus stat as always with condensing boiler part L blah bla blah
so yes stat required

 

[diamondgas]

As above Frank ... He should have filled out the Benckmark paperwork in your manufacturers installation instruction booklet also. There you'll find that the boiler should have an interlock (timer) & room thermostat fitted. A programmable stat does the work of both, bye-the-way

Thanks diamondgas i had seen that document but did'nt read it properly just looked and it ticks the box on room thermostat and programmer/timer

Well if it was me I'd have to hold my hands up and put one in for you. I can't see a reason why they didn't.... Well ignorance to current regs maybe!

Could be well worth asking when you'll be expecting your registration certificate too!!!

 

[frankm]

Diamondgas
he did mention the registration certificate and i would recieve from building control shortly

I know a lot of people who don't put TRV's on towel rads. I know its regulation but the customers complain of low output so they don't bother anymore. Even though towel rads don't give off great heat in general. It's what I'm led to believe, anyway. Any correction to my thinking/advice?

 

[AWheating]

no trv on bathroom and hall, no room stat?? sound like somebody needs to read up on current standards.

you may be able to get an plug in/wireless programable room stat for your boiler? would save time and mess of rewiring a new stat. worth a look.

always fit a trv myself (up to customer if they remove it), and try to oversize towl rail rad but space is always a problem.

 

[Kimou]

Yeah, space is an issue. A customer will praise me for a great job, but that'll soon turn to seething anger when they're bending over drying their tootsies and get their crack branded by a 6 foot blazing griddle. :rofl:

 

[frankm]

just a normal rad in bathroom dont see the point in a towel rad/expense

Frank

 

[SafeGasInstall]

as above must have room stat ,along with power flush central heating filter and a programmer

 

[AWheating]

you can always fit a normal rad and a small towl rail rad over the baths non shower end if there is room, in the right situation it looks good.

You have got your answer, interesting that the engineer said you don't need a room stat because TRVs do the job because this is not the case. As someone mentioned a room thermostat also acts as the boiler interlock which is required by building regs.
In plain engliah this means it turns it off when you don't need it cos your house is hot enough.
Each TRV only shuts off that rad, the whole house could be hot enough but the boiler doesn't know.
BTW, you don't have a TRV in the same room as the room thermostat.

Personally I think there is a good arguement for not having a TRV in the bathroom, why would you ever want to turn off/down your bathroom rad? But that is a whole different debate. My understanding of building regs is that a TRV or other form of thermostat should be in avery room.

Went for a cheap job eh? Guy probably can't wire one up for you so is bluffing. You should have one and even better get a programable one. This is pretty normal for low end installers who do cheap jobs must have got the Remeha on an offer as that is a good boiler.

 

[frankm]

Thanks for all the comments

I dont put a TRV on towel rails. Regs state they should have them on all rads, but its not compulsary if the customer cant afford the extra expense of having them installed with a new boiler. So I wouldnt worry about that, it will be better without a TRV on in my eyes. It should have a room stat though, but alot of customers always want a cheap job and end up with bits being missed off to keep costs down. Check his quote and see if he quoted to install one.

Theres no need to put a trv on the hall as that is normally where the room stat is. No need to put trv on bathroom as most people like them nice and hot, so no need to turn it down and its not a living area so doesnt need trv to meet regs
