Combi Boiler Replacement - are thermostatic valves necessary?

gartshore

Eliteheat i dispute your opinion on saunier duval boilers , they get very good reviews from which amongst others , i have been fitting them for a while now & have found them to be reliable & efficient , a fellow contractor employs nine installers & has been fitting them for three years going into hundreds of installations & has had one engineers call out for a minor issue , remember not so long ago many people where bad mouthing valiant boilers now they are an excellent product , remember they are made by the same company as saunier duval & glow worm , the same engineers repair all three makes i have spoken to a couple of engineers & they rate all three equally in there appropriate price ranges .

Thanks for the quick replies, I'll look into the valliant 831, and an RF programmable controller & thermostat!!

Are there any RF programmable controller thermostats you can recommend and which are the ones to avoid?! Cheeers!

Good afternoon: Have the Corgis quote an all inclusive price i.e. boiler/TRVs with a dedicated RF programmer/themostat from WB ... http://www.worcester-bosch.co.uk/index.php?fuseaction=product.detail&con_id=125934&detail_id=126252 or similar from Vaillant http://www.vaillant.co.uk/installers/controls_-and-_diagnostics/Controls/

In that case I apologise unreservedly.

I still wouldn't fit one though!

I don't believe what I've said is "wrong" per se and I'd agree with you that what you suggest would be a better and more efficient solution. What I am saying is you can't force it on the customer. If you swap a boiler or a radiator for instance, you can't force the customer to have TRV's put on their radiators. IIRC Part L effectively says you have to suggest it but the final choice is the customers. Note that the parts andrew-b quoted say "should" not "must".

Nope, you are right and you can't force energy improvements on customers.

cocksy boy we seem to be straying from your origonal post i fit lots of worcesters my preferred are the cdi models which have a wireless kit available & really good hot water outputs , the thermostats on the rads are always a good idea , more controls , more economic use , remember trying to save a couple of hundred pounds on the installation could cost you thousands over the years .

Whilst thermostatic valves may not be necessary, at £4 to £5 each and a few minutes to fit while the system is drained, it's well worth having them.

I agree with the post above,

The company i work for (the one that everyone loves to hate) will not install a new boiler without adding trv's/room stat.

Any new system has them fitted, not even discussed with the customer - they are automaticaly fitted simply because it is the most cost effective money saving thing to do,

and i was on the same line as eliteheat, i thought they had to be installed. I know Scottish regs differ from English ones, ill need to look it up

Hi Guys,

Cheers for all the inputs. I'll go ahead and get them installed - they aren't expensive (although I expect the actual labour costs of installing them will be significant!).
I'll also talk to the guy regarding the thermostat and ask him which one they are going to use. Cheers for all your inputs
