Thanks, thats still my thinking that the thermal store looks like a nice efficient option just a bit unwieldy to fit and since pricing unvented, how much more they cost! Ive attached a floor plan to show where the fireplace is with the tank going in the utility room. . We are still only at...

Ah i had not considered that, We have a rad(s) directly above the fire in the loft conversion so this may be an option. Does a heat dump have to be separate from the main rad circuit? Im guessing this works by using an electrical valve that diverts back boiler to heating coil via pump...

Hi guys, Im researching what route to go with for our heating system. Currently only the rads we are keeping are still in place, everything else is being replaced and we need to finalise this so it can be plumbed before getting insulation/screed done. I like the idea and flexibility of a...

Cheers Tony, We are quite lucky in that we are in a soft water area so not expecting too much trouble :) Had a plumber out last night to spec up a thermal store and he reckons its not going to be practical for what i want to do. He reckoned a 300l tank would be required which is close to...

Thanks for repiles and useful info :D Im only 2 mins from AJ plumbing (Ballynahinch) so they are likely to be my supplier provided they are competitive on the UFH, coming in good with all the main pipe work, fittings and cylinder etc so far. Couldnt see the benefit of the System 70 myself...

Hello Got a few queries about poly pipe in pipe and getting it from the floor to the wall. Currently only subfloor is in so we are running everything under the 100mm insulation in pipe in pipe then will be installing UFH above. I know there are to be NO joins under the floor but im unsure...

Was thinking last night Given that a thermal store is more or less a heat bank for the boiler and other heat sources. With a heat exchanger to give DHW, Is it possible to plumb a plate heat exchanger to the boiler flow and return directly to make what is essentially a DIY combi...

Thanks for the reply and some good questions, Bungalow is an old 1930's solid brick building (60m²) with a more modern cavity walled extension (40m²). We are fitting 100mm insualtion to the floors and 75mm interally to all external walls and fitting as much as feasible in the roofspace...

Jay'sus That was a long post, if you cant be botherd reading it all, skip to last few lines lol Apologies

Hi guys, Having finally had our sub floors laid we are in a position to start thinking about plumbing. Currently the only pipe work we have is a 15mm copper main through the kitchen wall (giving approx 22l/m), flow and return going to 1 rad in conservatory, pipe work for backboiler and all...

All sorted, :D Tamper alert, was down to a weak spring on one of the tamper switches. After much searching I got the receiver installation manual, Managed to reset the receiver and re learn the transmitter to it. Think because the battery in the transmitter was dead for so long it...
