I bought a cheap ASHP from ebay, thankfully from a dealer, and thankfully that dealer was owned by a well know builders merchant. It was advertised as new and with a 12 month guarantee. It was 11 months before I installed it and tried to commission it. It did not work. It took a fight (CEO of parent company) but they honoured the guarantee and replaced it. Good job it was not 13 months before I tried it.........

I used hand held circular saw. As above it clogs up like mad. I ended up unscrewing one side of the cover (like you do to change the blade) and leaving it off and being very careful. I still have all my fingers. Re your corner blocks. Do they really need to be fixed to the frame? The panels will be secured to the nearest batten that won't be far away from the corner, so to me it seems the important thing is they are joining the corner joint together so there is no movement, so just screwing the 2 corner battens together and then screwing the panels to the corner battens and nothing is going to move.

Like @joe90 I know my limits and precision joinery is not on the list. I paid a trusted joiner to do my Oak kitchen worktop and hang my upstairs doors. Unfortunately I could not get hold of him for the downstairs doors so I hung them myself. Even though my joinery is not perfect, it is a damn sight better than this door, just by doing things slowly and carefully. Best of luck getting it resolved.

I have a Raspbery Pi Music box as the core of the home audio system, it's main function is to play internet radio stations or play music stored on it's own memory. It is also capable of streaming music from another device via Upnp Until just now I have not tried this function. I have installed HiFiCast on my phone. Initially if did not find any "playback devices" to stream to. Help suggested the best place to look was in the router (A BT hub 4) What I found there was Upnp was enabled, but by default "Extended Upnp security"was turned on. I turned that off and now my own phone, an old Samsung Galaxy S3 works, it sees my Music box and streams audio to it. SWMBO has a new Samsung Galaxy S12 so obviously a newer version of Android than my old phone. I have installed HiFiCast on that as well, but it will not find the Pi Music box. So my assumption is it must be some android setting that is stopping this which is where my knowledge runs out. Any ideas? For background the Pi Music box is hard wired via ethernet to the router.

I have never seen that as an approved method.

Air lock probably. If a bath mixer tap, put your hand over the outlet and turn on the hot and cold taps and after a lot of gurgling you might blow the air lock through.

UFH works fine with an ASHP and spreader plates. Just do it. Ignore the ignorant sales person.

An ASHP will do 40 degree UFH water comfortably. You size the ASHP based on the heat loss from the building. Your present gas / oil usage should give you an idea, if you can measure the usage on the coldest day in winter.

Last time I did a tiled kitchen, I left long tails on the sockets and temporarily surface mounted them. Only when I did the tiling did I cut the final socket box holes to line up with the tiling and flush mounted them.

Just make sure you document it all so the next person has a chance of understanding it.

I am missing something here. Our electricity and water was on site when the only thing there was the static caravan. All fully energised and functional.

I would work on the figure in G 65, heat loss at 25 degrees delta t. assuming you want the house at 20 degrees and it rarely gets below -5 where you are, that will be the worst case heat load on the coldest day you are likely to get. So that's a figure of 9883W Now you won't want the ASHP running 24/7 and in any case it will spend some time heating DHW so I would be looking at a minimum of a 15kW ASHP Now go and tweak U values and see how much better you can get that figure. For a comparison, I used the figure in H 65 as -10 outside is not uncommon here and my heat loss there is just under 2,5kW

Lesson for other self builders, at step 3, immediately accept the quote, pay the £3K and order the supply so it is the first thing on site even before you start building.

Back bench MP's and 1922 committee might sort it. There seemed quite a few who might take that route in the house this afternoon.

Do what you can at the build stage to reduce heating need, so lots of insulation, good air tightness, good windows, low temperature under floor heating, Unvented hot water tank (not thermal store) Then the heat source is less important, a small system boiler will do it for now, as will an ASHP. You could also swap for an ASHP later, I am not awre of a need to seek DNO approval for a retro fit. But if you have a low energy house design that only needs a small inverter driven ASHP then I really cannot see why the DNO would say no. If you want a boiler for short term I would probably go oil with a small tank, and avoid the cost of a gas connection. Choose an outdoor oil boiler and it's a relatively easy swap to an ASHP.

So that it appears to conform with regs. Ponder on that first. Alternatively can you not paint steels with a special paint to make them fireproof? again what you can't see........

That plan falls apart when the plasterboard installer moves those pesky wires out of the way so when you drill the holes, there are no wires within fishing distance of your holes. See post 4

What is this hourly recirculation?

Just how much do you expect G3 sign off to cost? I am a little unusual that I know a lot of trades, but one plumber just came and checked my pipework, connected the cold feed and tested it all and signed it off for not very much money at all.

It looks a good idea from the grid point of view but a very very very lousy idea from the car owners point of view. Something I would not allow if I had an EV, why would you want to allow extra charge discharge cycles on your battery? Obviously a question to ask when buying a used EV, has it been used V2G and if so reduce the valuation of the vehicle accordingly. Time shifting and grid storage is something the grid operator and energy providers should be funding, not expecting EV owners to dig them out of the hole they have created.

you won't do it in one fitting cascade a few and you will get there.

A whole load of offensive and dam right rude posts have been removed. Learn to behave like grown ups.

Lets hope the electrician (or you) remember exactly where the cables are, and hope the boarder did not move any of them.

Odd. I am seeing your locations. Is this only visible to staff now?

Standard stuff, especially if it's to help you sleep rather than because a SE says it must be there. Just a stack of standard timber of whatever your wall is made of, e.g. the ridge beam of my house is supported partly by 2 internal walls that have a stack of three 147 by 47mm C16 regularised timbers running up inside the wall.
