ASHP & triple glazing

[Ronski]

You're tempting fate just by mentioning it.

Hope it goes OK, and the weather's better than it is here at the moment, at least the solar panels are getting a much needed clean.

Oh I know.

Follow on mail from ksm saying both trapezoidal units have been inspected at their premises and approved for installation beginning 08.00hrs Tuesday 10th June.

4 windows to go and we'll really see how it all performs together. External temperature is 12 degs today. House has been sitting around 19 degs for weeks now with no noticeable ashp running to heat it. A few small wbs burns and that's been it and they've been for the ambience mostly

[Joeboy]

Temperature is 11degs outdoors and recently came off a pretty much all day rain run. Wee bit of bright now & then but essentially (pish) as far as we go.

Nonetheless, the home is again sitting at 19.5 degs. Me n No1 just back in from a pint & dinner.



I can't differentiate for sure between the HW running and maybe the house heating kicking in surreptitiously (always wanted to use that word).

I'm reasonably confident that it hasn't and the house just doesn't leak the way it did plus solar gain (hell of a combo).

Just to make sure, I've dropped ashp thermo to 17.5 degs. Let's see what it does over the next couple of days?

After 28 years in this home I can say without a doubt that the change is phenomenal but I can't yet put it all down to the 3G. I want to what with the upcoming Seq 3 of the 3G fitting but need some of that late Summer low temperature mornings to confirm.

Oh aye, and the rest of the windaes.

When you started the 3G project, Joe, I was going to ask if, when finished, the house just felt more comfortable at a lower measured air temperature.

I just have this feeling, and I’m sure someone will have a term for it, the less heat loss in your overall environment, the more comfortable you feel irrespective, to a degree, of the actual air temperature.

Probably not described that well , but I hope you know what I mean

Me, surreptitiously, asking

Edit - even though it looks minimal, you’re going to notice a massive difference to light/view/openness when those trapezoid units are in

Mucho gracias! There's about 9sqmtr to go in next week. That's about 1/3rd of the entire home to Air glazing barrier. Concentrated now in about 15% of the floor area of the prop.

This room is defo the litmus/bell weather etc. All that aside, already I can't believe in the rest of the home the temperature modulation and massively efficient ventilation we are seeing from the change in window design (tilt & turn to top hung).

The crazy heat up via solar gain has largely departed due yo the 3G and the cool down (at this time of year) has been almost stopped in its tracks.

It's actually surreal, I'm still waiting for the gotcha!!

But it's not coming, it really is this good. Stinsy dropped in a line a few weeks back, i'm paraphrasing now "you'll be relying on background heat sources now". Body, transformers, cooking, waste heat from showers etc.

I thought at the time nah, in this old shith**? no chance pal! (Sorry, that's how my mind works). Yet he was the catalyst for the 3G with his throwaway line a few years back on the condensation forming on the outer pane and the why of it.

He's in London right? So that means ice forming on the outer pane up here. I'm happy to have a bit of hassle to see that.

Aye I know what you mean. The skin knows 0.1deg C change. I'm sure it feels all those low temperature flows.

As we are now and soon to be, oversealed with no mhvr system I'm going to go for shock changing of air. The idea being that the solid fabric of the property and it's contents at an even temperature acting as a full home storage battery will barely flicker as we 45 minute blast the whole prop to air exchange in Winter. I'll still run the 2 dehumids for moisture.

We used the E-glass/argon filled solution about 10 years ago (was 3G mature then ?) and have noticed similar effects - the first time you see the external condensation is a bit freaky !

Also, we used to open the bi-folds facing the sun in the summer to cool the house

Now, keep the sun facing glazing closed, open when in shade plus opening the north facing side glazing.

Still, this is nowhere near your position with the physical glazing solution.

It is interesting how modern glazing can maintain a comfortable home environment, if you’re able to flex the opening/closing etc.

Great project you’ve undertaken - loads of evidence for others to use

Thank you BTB, I stumble about and trip over these things in passing. It's nice to leave a wee trail of what we found for those that come along after the fact. Did you ever look into the price difference re argon/krypton . Holy hornswagle batman it is mental.

As to the maturity of 3G? The lock opened when I found Liniar Zero 90 Sorry, I know that reads like an ad but I'd seen what I expected to in the 21st glazing fowk. Then I found that.

Hers a thought and it just popped up. Yes to the air/heat control but thought being that the E blinds distance controlled add another layer. Can't ventilate but can reduce solar gain... The blinds have been a true revelation.

Did you ever look into the price difference re argon/krypton .

Nope, it was three great drivers - availability, affordability and timescale.

And not necessarily in that order

Would we do it differently given different circumstance ?

Absolutely

You can have any two but ye've gotta give up the 3rd. So it is in all things. Apart from hookers maybe? But that's just me blue skying.

The previous 2G set up here which was installed in 3 stages across the decades & building codes was all put in for a price That would be the price of all that I could afford armt a time and the next offshore trip. It fairly shows the gulf now between the what was 2G 20yrs back and what can be had nowadays for not massive amounts of money.

The trick for me was when I read about a set of building regs that this Liniar Zero 90 was designed and aimed at and then the regs were reduced as being too difficult for Bob The Builder (did you see what I did there) to achieve on an estate/scheme wide basis. Yet the glazing and frame range was launched at the better spec anyway.

I've always been one to press my advantage, I don't sit back. When I found out about this gear I went at it. It's been grand, the only caveat is to get the people in place willing to work with you or be confident to diy it to a high standard.

Are ye gonna rip oot & go again BTB? I'll come down and help.

Absolutely not - we’re content with what we have for the reasons we have them ( )

Not convinced, based on achieving a similar aesthetic and efficiency, it would be justified.

Currently works well for us.
