ASHP & triple glazing

[cojmh]

The unit being so small.(demo) made it a pig to get the beading in. I like the black bars



Also that you can't see the middle pane unless looking at the kite marks.



One of the guys came up with the excellent idea of making the lower and triangular units one piece. We said yes so they're away to see if it can be made at that size.

Roll on March to see these in. Went for top hung on all windows that are openers.

I agree on both the black bars and the fact the central pane is totally invisible apart from the etched marks!

Did you get to remove the glazing from the frame? I was impressed when putting mine in that there was no need for packers at all and the glass unit was such a snug fit ..... very impressed - although I am comparing to the very old and crap units currently installed in the house.

I think you will be very happy with them when they go in.

I haven't done that and don't think i will. I hope they get more 3g sales and this can be their sample window. No point my gouge marks being on it! Also noticed there's very little change in light if any through the 3 panes. None of that green tinge. Swmbo is impressed and that's a good sign as she doesn't miss much.

Co-incidentally my 15 yr old 2g units are also now looking crap. Once you start looking at design with that much more experience in life it's very easy to improve on the outgoing design.

I hope they can do the the two big lounge windows as single units. That will be a wow moment. Hey ho if not but now that the seed is planted...

Andy, we both have similar walls by the sound of things. I would be wary of filling the cavity behind plasterboard (lath and plaster in our case) with something that could hold and wick moisture across the gap.
I know what you mean about the timber always seeming to be dry, but the houses were designed to make sure there was adequate airflow to stop damp penetration.

I'm very keen to make sure that I don't disturb the equilibrium. It's a strange one as there is so much air movement behind the plasterboard that I'm not sure the granite adds a huge amount of insulation value. That means that there isn't a huge amount of insulation in the house, but adding any more means reducing the already small room sizes more if I am to maintain any gap.

As for rats.
We have had success in our survey warehouse with goodnature A24 humane traps.
Gas fired piston to the head and the rat or mouse falls out of the way, trap resets for the next to shove their nose up to the bait in the kill zone.

Amazon do some knock offs that are cheaper but the goodnature bait pouches have no alternative that we have found that work as good.
Each gas canister is good for about 24 kills.

I shall look at them. They always start coming in the garage so that is an interesting idea. Not zero cost but then neither was the wall chewed or window frame.

Quite a bit of insulative value from Granite, not as much as sandstone but it holds heat much better and doesnt get as wet which both help balance it out. Thise factors dont play into Insulative value, but the definately matter.
I am trialling Joes idea with perlite in our downstairs cloakroom, so can easily keep you informed of any issues if you want to use us as a guinea pig for the rest of the winter before making your mind up.
The benefit is its easy to put in and easy to remove the same way with a hole lower down if it doesnt work.
Gardeners will gladly take it off of our hands for cheap if posted online, and if i dont use it in my own garden. So is worth the test for such a small room.

Had a very pleasant hour and a half in the loft taping the armaflex joints and cutting/fitting small pieces of pipe insulation where needed.

A personal retrofit should be on any HP owners list of things to do. We have more time to take it to a slightly higher standard.

Example, top outlet on side of HWT.








I am also insulating the pipe clips now that I've seen this pic.

Just stumbled upon this page whilst noseying about on your glazing stuff

Not sure if this applies or is relevant etc, but the idea still stands.
If the glazing company only have that small window, and dont have many customers, may they discount your job in return for taking photos or you allowing potential customers to come and oggle your windows?!
Wouldnt be keen on the latter myself, stranger danger and all that, but it is worth a thought.
If they want to get more 3G sales they may need testimonials and photos and real homes to show.

Can't see myself being that public spirited. A few photos for their website & a testimonial is as far as I'll go.

Give or take a dayorso and that's the first month in. Weather has been a good test. Been as low as minus 10 and laterally as high as 11 degs. I'd say 60 to 70% of the month was at sub zero.

My cop is all to beep but it's in hand for rectifying. Got the fallback of the cu meter count and also the Valliant app count.

2,479kWh space heat
500kWh hot water

2979kwh heat generated ÷ 947kWh electriciry bought = 3.145 cop

Not bad for a frankly pish month and my not having a clue what I was doing (thanks Iain). Maybe about 3% of this has been PV run, about 17% at fullbrate while I got a handle on it and the other 80% has been at low rate. There have even been a few days when we've exported.

Nothing wrong with that COP, average temp. for the last month (17th December till today) has been 3.6C, low -9.8C and high 15.2C.

I've put my heat pump on to the active setting for the internal temp. to see how it compares to pure weather compensation.

I'll be interested to hear how that goes, (active v's pure). We've found it to be good. Can overshoot a little on req'd thermostat temp but has been great in response. The thermal imaging today in the loft was an eyeopener. Worth doing if you haven't already. Can have a shot of my one if you want?

Can honestly say and I'm saying this to those on the fence or pre purchase of an HP. I can't see any downside to it at all. It's all upside.

The bills are lower
The house is warmer
We've got more space in the loft
The unit is quiet
The cop multiplier opens up other avenues in existing RE strategy.
It's really like magic as its taking global warmed air and cooling it.
No ff gas consumption.
75% reduction in log volume burn.

I genuinely can see this unit paying itself off quickly. If the interest free loans are available across the Nations, why not?

I'll be keeping a close eye on the graphs to see how it is doing, thanks for the offer but I bought one when the loan one from Octopus never appeared, they are very useful.
