ASHP & triple glazing

[Joeboy]

Our heat pump is coming up for a full year of operation in a couple of days, SCOP is 4.12 so no complaints here either.

Keep enjoying it.

That is brilliant Iain! Do you have figures for the year before to compare it? I am agog at what these units do. In particular in lower irradiated areas like ours. Solar gone? Yeah, yeah!

We only had about 4kWh solar today. That leaves 4.8kWh to pay for. (33p). Although I'm exporting at half load the noo. So that makes it another zero cost day. Sorry I'm.banging on about it but it's surreal this early in the year.

In previous years we used oil for our heating along with the WBS, to try to give an approximate figure I would compare the cost of oil to give the equivalent amount of heat the HP has produced for the year.

So 30640kWh from HP would need c.3404 litres if oil boiler was 90% efficient, avg. cost of oil =60p/L which gives £2144 (incl. VAT).
£2144 for heating only, whereas with solar PV, battery, HP and Ripple my electricity credit balance has increased by £486.44 over the year for all my electricity use (18588kWh).

P.S. WBS has not been used since HP was installed.

That is outstanding

How is this possible? Me n SWMBO were looking at blind colours online at 08.30hrs this morning and ordered some samples. At 15.30 hrs they drop through the door.

That was completely surreal and possibly a glitch in the matrix.

Are they not the ones you ordered Tuesday???

10 roller swatches on the way up.from the Southern Shire and swmbo can match what she likes at the local supplier .

No they were pleated blinds, i misordered. These were defo ordered this morning. Just shows. it can work! There's a level of complexity in blinds that I'm just not enjoying or engaging with. Roll on the 3G!

Well that worked out well. We picked the least hideous blind material together and i've priced them up. Note going forward kids, don't pay the rent on some companies premises unless you absolutely have to.

Scottish shutter company £7,703 all electric (self collect, self install).

Garioch Blinds £2,106, all manual (company delivers & installs).

Blinds 2 go & Garioch combo, 2 manual trapezoidal verts and 3 electric rollers £1,638 (company installs the traps, I install the rest, all delivered). No blind on side door.

That is an incredible spread of costs (4.7). Wilder even than the original 3G hunt (3). The moral of my tale is, dig, dig, dig find it ALL out then pay the acceptable price.

Got to be done, not sure what the Scottish shutter company was trying to achieve, anybody willing to spend that amount won't be the sort of person that installs them themselves.

I asked them to quote self fitting. Not a big deal as they sell a lot to the Scottish Islands remotely. As a throwaway the fella said it was worth about £500 to diy it.

The interesting pov that I see is that the person who will diy it is the person that will have the money in the first place to entertain those blinds through longterm behaviour patterns. Or maybe not.

Personally I wanted as level a quote field as I could get for comparison. As has been the case times without count SWMBO made the critical key unlocking suggestion as to why not do the 2 traps with sloped verts? I was already out the door and spending £2.5k on the traps alone. Never underestimate the powers of SWMBO.

There's a guy on FB Aberdeenshire selling 2200mm x 220mm x 19mm plywood boards new. Just got 20 for £35.

Seems a very good price to me? I'll be using mine to rework the loftspace post ashp install.

He told me a horrendous ashp story. Truly horrific, he's back to an oil boiler now. Oddest thing was he said he had come up with over 24kW figure for the heat loss calc after a 10kW system was intstalled. A true litany of disasters in all directions. The cowboys were most definitely in.



As the letter box will be going in a fortnight or so I thought I'd get a solution in place. I don't particularly like it but it'll get the job done.

Loads of shitty HP installations out there.

The problems are:
- Gas boiler fitters didn't need to brother doing any calculations because you just chuck in an oversized boiler and let it cycle frequently.
- Gas boiler fitters don;t have to bother doing any pipework calculations because pipework is generally oversized seeing as the property has probably had it's loft insulation and windows upgraded since the system was originally installed.
- Colleges don't actually teach youngsters any relevant skills.
- People try to use a HP like a gas boiler, cranking it in the morning and when they get home from work, an delaving it off the rest of the time. They then wonder why their bills are high and their house is cold.

It was a bit weird. He kept going on and on about it. To be fair it sounded like an absolute shit show on every level and aspect and it was across 3 years. BUT, he had magic Box syndrome and when he said 20+ kW heat loss (might have been 24kW) and didn't mention any Insulation works even since retrofitting back to an oil boiler I realised he wasn't seeing or willing to see the full game board.

I felt sorry for him but also thought 'take ownership of what you didn't do too and learn from it'. He wasn't going to, that was obvious. Quite literally 'A big boy did it and ran away'. On the removal of the system including rads. Someone had scribed "wan**r" on the back of one rad with a Stanley. Sounds like there was quite a bit of friction to say the least!

Thanks again Fintray for all the potential bullets you helped me dodge

Great plywood though and outstanding location. I cant even count as high as 24kW let alone imagine losing that much heat.
