Evening guys...and gals.

Been asked for some advice by the mother-in-law and she has confused me. Apologies if this is a simple question but I'm still very much learning!!!

She has just moved into her new home, probably 30yrs old. She has her system boiler in the loft with cold water cistern and hot cylinder in the airing cupboard. She has a Honeywell programmer in the kitchen and room stat in the lounge. Two Rads have TRV's on (downstairs wc and a ground floor bedroom). She was looking at having TRV's in every room....although I explained it's not good to have one on the rad in lounge with stat as it could contradict the room stat. Also mentioned it could work as a safety device to protect the boiler, even though I'm pretty sure her boiler/pipe work will have a bypass.

She then tells me she had a British Gas engineer around and he agrees about the protecting the boiler but has said to put TRV on BOTH the rads in her lounge. Her main issue is she wants her conservatory heated beyond the temperature of her lounge. She has one rad in the conservatory and would like that to heat for longer. Hence the reason she had the BG man around to advise on how she could accomplish this problem. Conservatory is only about 8 years old.

Many thanks for any advice anyone could offer, either on how she can overcome her problem or my confusion as to why have TRV's in the lounge with room stat....which I had been taught. As mentioned, I only have a year or two experience and am sure the BG engineer and yourselves have so much more!!!

The conservatory radiator should really be on its own zone which would do what she wants and to comply with Part L.

You're better off sticking and additional electric radiator out there.
 
BG man is a plonker, unless she moves the room stat. Best option to have conservatory on separate circuit with its own programmable room stat, but why try and heat a glass covered room in the first place when we are trying to be more nergy consious, best option would be jumpers and blankets if she wants to sit in a cold room in the winter.
 
Thanks Croppie, I had already suggested a little electric rad/heater which she already had sitting in her garage.

Cheers Lame plumber too. I don't actually think it's cold in the conservatory...might just buy her a new jumper for her birthday. She has some romantic plan of sitting in there all year round watching the world go by!?!?

So I'm assuming my initial thought of having no TRV in the room with room stat is still correct? She gave me the mother-in-law glare of 'he doesn't know what he's talking about'.
 
Show her this thread and tell her to count herself lucky he didn't sell her a powerflush.

BG man's a cretin.
 
I'm with croppie on this one,

you can get electric heaters that mount to the wall and look really tidy, that's what I always suggest and fit for customers, and just turn them on when your using the room no point in wasting money heating a glass room
