ASHP & triple glazing

Its the government grant thing that people on low incomes can get to have green energy freebies thrown at them.
Previous owner had all but moved out of the house but qualified and sold it as soon as it was done!

Getting a government freebie of suxh stuff sounds nice in principle, but if the poor b*ggars are left with installs like mine then they will wish they'd paid!

2 year warranty, but after complaining to the company and them dragging their heels I complained to NICEIC. Who will give 6 years if the installer is one of their members. They/certsure oversee the eco grants along with MSC. MSC told me to go straight to them as they had more clout.
All a bit confusing but they are getting it done and holding feet to the fire, so i cant complain.

There is SO much cynicism in companies pumping govt RE funds and providing horrendous work standards. It should be prosecutable as its fraud of taxpayers money. Makes me sick to think that something well intended is polluted in this way. Where's the council (being local govt) surveyor to keep an eye on the quality? Sad, sad, sad.

I am very happy with the build I'm seeing here. I don't think there could be a higher quality tried for. Upstairs remains as 10mm but it's a relatively small set of rads in an uber insulated section of the house.

It's easy to get stuck in the mind about 0degC and forget about energy being present all the way down to absolute zero. Nope, still not clicking with that idea!

Looking very nice Joe.
Best of luck for handover today.

In agreement with all you have written above!

I completely agree. It is next to impossible to get a competent tradesperson who takes pride in their work. And as soon as any sort of grant is involved the standard of work decends to "council quality".

Looks as if you have gotten yourself a top-notch install. Don't forget that in your case the CoP is magnified by your battery and ToU setup. Let me explain:

Your "7kW" inverter might pull 875W at 50%. However how much heat you get out of that 875W depends on your system design (big enough rads and high flow rate). Maximising the amount of heat you get from a low-and-slow HP doesn't just mean less electric used but, critically, it means less peak electric used. The lower your HP runs the easier it'll be to keep your 16A inverter to cover your entire consumption when your washing machine heating element kicks in (for example).

My point is that the additional time and disruption you have endured to achieve an A1 quality install will be well worth it.

And now you've seen the amount of work it takes to get a good install you can understand why cowboys are tempted to sling the HP in, get gone, and pocket the grant. And on the same note, it is doubly upsetting that newbiulds are being built with teeny rads and microbore as we speak!

15.00 hrs fill & bleed.
16.00hrs switched on.

Woo Hoo

I'll be looking for your data on Heat Pump Monitor.

Theres a ton of room on that roof for more solar!

That might take a while! 1206ltr flow and it's all slowly heating up. HP is running flat out in this it's first cycle to
raise 8degs to 45 degs. I did a full body press against one of the vertical rads. Great!



As to the solar. Van is next up for that treatment.

Have fun tinkering once the installers leave!

Thank you, thank you. All very excellent. At minus 4 we are running at 2.6 cop which is mind blowing to me.



It's only been.on for a few hours yet the bathrooms are great and the cold spot at the bottom of the stairs isn't.

The only negative was the immersion heater running for hours earlier before HP switch on and largely flattening the stack. The HP running up finished it off as it was cranking full whack to begin with. It's modulated down. now so we can get a feel for what to expect down the road. Very indeed.




Edit, that's better!

Here is what I’d do:
1) Set your flow temp as low as you dare (eg 25℃)
2) Set your weather comp to increase flow temp as outdoor temp drops (maybe 40℃ flow temp at -5℃)
3) Let it run and see how it does. Maybe take notes morning midday and evening of outdoor temp and comfort levels. Adjust accordingly.
