Thanks for all the replies. How exactly would you go about making the joint then (bit of a plumbing novice, so don't assume I know anything!) ? The Loctite 55 container suggests something like 7 or 8 turns on a 3/4" fitting. Would I still expect to turn the fitting all the way until it...

Hi Wonder if anyone can help - I'm trying to work out what type of couplings I need, to attach 22mm copper pipe to a plate heat exchanger I recently bought. The PHE has 3/4" male BSP outlets, fairly short, with flat faces. I bought some 3/4" female BSP -> 22mm compression couplings, but...

Thanks for the reply. Yes I will turn the isolator off during summer months - I'm thinking ahead to later in the year. I won't want to be constantly carrying heat away from the store when none of the stats are calling for heat (either due to times or room temps). Will have to see if I've...

Hi all I noticed something odd recently, and wondered if it might be due to thermo-siphoning, and if so - how I might stop it. At the centre of my DHW & CH system is a thermal store. The ground floor of the house is heated by water-based UFH. One of the outlets from the store feeds...

Thanks for that, it's an idea I hadn't thought of. Sounds easy enough to implement, might take some experimentation with thermostat settings to get a reasonable response time of rads when TRVs call for heat but the pump is off....

Hi all I'm in the latter stages of a large-ish selfbuild project and need a bit of advice regarding heating controls. At the heart of our system is a thermal store. The boiler heats this directly when the twin stats on the store call for heat. Downstairs we have UFH throughout, there is...

That looks like ideal stuff, thanks. (Although it's not actually being embedded in screed or concrete - it's just laying on top of the concrete slab with Celotex insulation board sat on top.) I like the idea of being able to have one long length without joins in.

Hi We're part way through a selfbuild project, and I'm at the stage where I'm starting to lay the insulation sheets on the ground floor slab, in preparation for UFH pipes & screed. However, we will be having an island in the kitchen, which will feature a gas hob and electric oven. My...

Can anyone help ?

Hi My first post on these forums, hope someone can give me a bit of guidance... We're partway through a selfbuild project, and all our staircase parts have just been delivered. At the moment they are stacked up in one of the rooms and looking mightily confusing. The house is 3 storey, and...
