Its actually a swiss one that's tickling my fancy :) I don't see how its going to be cheaper to fit something without the RHI over 7 years? Its worth 28-31k for me over 7 years. If you say a 10k bill to install something decent, thats my cash and a minimum of 18k back. A 5 year warranty...

Tony I'm sorry you found me rude, if you actually read its just been a bit of harmless 2 way banter. my flow rate off the new incoming is 18lpm at 5 bar. I get 3.8 bar with all taps open still. Thats on 15mm pipework and stopcock. on 22mm I should get 27lpm at 3 bar doing the maths...

I only live 3 miles from a city. However I have no gas to the house, it is in the road if I want to pay £1500ish for a connection to the house. I'm not looking at an Italian or eastern European boiler, one from somewhere where they've been making them for 20+years, from a country where its...

Good use of the term smeg :mrgreen: I have it, don't have to use it. Just the best way to get DHW when using a pellet boiler really. There's a good few ways it seems.

I've a boxed new oso250ltr unvented cylinder so its no extra cost to use it. Just the most efficient way to use the pellet boiler to heat it, trying to prevent too much cycling. Although effecta do say that their new range are designed for domestic use(all their range is domestic) and doesn't...

Not at all, I've multiple choices for how the system goes, I can spec the system to exactly how I want without having to follow what anyone 'installer normally does'. The only thing I'd like is good flow/pressure on the hot which lee seems to understand.

Hi, I've been looking into them, do they work well enough to match a mains pressure DHW cylinder? Any particular make 'better' than others?

You could argue that we're just getting some of the tax back we've paid over the years. With a 5 year warranty there's not much to worry about.

As you're such a smart guy you'll know that its not getting rid of cash, in my case its getting 3x my investment back over 7 years through the RHI. Do you have anything sensible to add or just preconceptions? I guess you know lots about them?

Well done for copying a post off the internet. Do you really think its any help at all or that copying a webpage into here means anyone will take your post seriously?

Its mixed terminology really. I understand what you're saying and have been looking into both!

Right, I'm going to have a biomass boiler fitted. Going for one of the Effecta range. What I can't work out, is it best to have a thermal store that is then pumped to a separate DHW cylinder for mains pressure, or a tank with a stainless heat exchanger fitted? Looking at 1000-1500ltrs...

I've been scratching my head, trying to work out how to ventilate a timber floor that only has one external wall. A room and hall way are having a suspended timber floor reinstated. Only one wall is external, about 2ft thick sand stone. How can I provide decent cross ventilation...

Hi, I've stopped the water/moisture entering. French drain goes in next spring when the conservatory gets sold. The room was completely empty when I did it, there was no other way. I'm not starting a variety of jobs, just removing all the damp plaster as I've a mortgage retention and...

The whole system is going to be on RCBO's, with RCD protection would straight conduit be ok or am I not reading it properly? Thanks for your useful input by the way.

There won't be any paper. I find the rules slightly confusing, sometimes I read it as PVC conduit will be fine, other times I read it as the PVC would have to have some protection. I've just found some 25mm oval which in theory means with a touch of lube the cables should pass quite easily.

Hi John I'm hoping to plaster the conduits in place and cable at a later date. I need to do it this way as until I've pulled other parts of the house apart theres a few cable routes left to sort out... I'd cover the conduit with a metal capping if needs be. I also need to decide on the...

A couple of rooms in my house are about ready for plaster. I've done a wiring plan, although I need to work out some routes etc. I'd like to plaster some rooms before wiring. Its lime plaster and about 15mm thick total. Some older plaster that I don't need to remove is about 40mm thick...

Its not a drain as its completely solid at the bottom, its got lots of compacted ash over it, 3-4mm, I think it might have been some internal coal type store from when there use to be a huge bread oven. That lintel is sound, it was a real nice find as the house has thrown up some not so...
