Mains pressure isn't great....yet to have dynamic flow test yet though. My back up plan is a Grundfos home booster if the shower is pathetic...!

I'm waiting for him to get back to me with his availability and I was planning to be his mate on the fix, just wanted to run the pipe behind the plasterboard and have it run to final location, it's possible that it will be a couple of continuous lengths of piping barring one elbow, so I was...

It will be the latter Terry, mains pressure 300L UV cylinder. And yes, cold from mains. Ty

Afternoon all! Need to start 1st soon on my renovation on my bungalow - currently constructing some stud walls and plasterboarding in the bathroom/ensuite areas. They are adjacent to one another and both of them have a wall that backs onto the loft area where the cylinder will be. I wanted to...

Looks like I defo need to get registered before 1 Jan then!

It's a complete renovation - all new dads and mainly UF heating to be installed. RHI is headache- renewable energy doesn't exactly get pushed very well or advertised at all.

When you say locate, as in ask the installer for them? Thanks

I was initially looking at ASHP, of which the RHI would pay me approx £6700 towards the £8-9k install....I had written off GS due to the install cost. But the RHI calculator suggests payment of £19000 over 7 years which puts GSHP back on the table....bore hole system.

.....or more importantly installer that will set up correctly! I'm satisfied that my refurb/extension is upto working well with one of these systems- but getting different advice/options from different 'salesmen'..... I just want someone with a good working system to recommend me an...

But I hadn't even put my white PVC boots on yet!

Doh just ignore my last comment above -teach me not to read all the replies first!

Puller how would I pump the system in a black out? TIA fella

Silly me - even if the boiler could be ignited by an igniter - I'd have nothing to pump the water ... oops.

Could a combi not supply a coil in the cylinder (thus providing a back up in a power cut)- or would money be better spent just popping the immersion on for 30mins to top up what the heat pump struggles with in cold months? Although I'm having a woodburner too, so I'll stick with that. Thanks...

Thanks guys, Just a thought - if I have an ASHP set up then I might need a back up for winter months, maybe I could have an LPG combi.....:rolleyes:

only a downoipe and drain approx 5m away. Should also mention on the same rear wall possibly there will be an ASHP (if I can't have the GSHP) and maybe A/C units mounted on a wall around 2/3m away. Thanks for looking

Interested in bottled lpg for our new house which is currently gutted. No mains gas. The wife and I would both like to cook with gas. I was hoping to position the bottles on the outside of the rear of the garage, with the intention that a pipe through the wall would run approx 4m through the...

I'm going to guess it's negligent in value, or perhaps it's a given constant, but if that were the case I would have thought it would have a value like Rsi and Rso in I values. However I have been looking at blocks called Perinsul which help reduce the cold bridging you would normally expect...

Thanks Tomfe After A LOT of research and driving myself mad, I've decided to stick with both skins Fibolite. Especially for the fixings side of things as One side is the kitchen, the other the garage. Then it will change to facing brick as the wall Leaves the back of the garage to create one...

Thanks fella. For the new inside wall (cavity- both skins, as the 'outside' is actually the garage) I have ordered Plasmar Fibolite's..... as recommended by my SE. But looking up the thermal values, I'm wondering if I'm better going for thermalites/something similar value wise? Any advice...
