ASHP & triple glazing

[Moxi]

I think we are all getting stuck on the plume, you are all of course correct that there will always be some form of visible plume but as I said earlier in my case the plume is lighter and more see through and because its not got as much water in it it tends to disappear faster and not go so high. I have seen condensing boilers that are not set up that jet a plume of steam several meters high on cold days and these are clearly failing to condense much of the water at the heat exchanger.

I suspect Stinsey is speaking of a very white steam laden large (long?) plume rather than the whispy short and fast to disperse plume that I understand indicated a condensing boiler functioning as intended.

With respect Moxi you are getting mixed up, like many other people who think visible steam is not condensed water vapour. Water vapour is a gas just like Nitrogen or Oxygen and is totally invisible, if you can see it it has condensed back to water droplets and given up the latent heat somewhere within the boiler. Doesn't matter where it condenses, even if just before the flue outlet it will have given up its heat to the incoming air. Mind you given that the flue outlet is plastic it will have condensed much earlier in the system TBH. If you get a 2M high plume your boiler is work just fine and I can tell you from many measurements taken the the flue gas temperature taken at the outlet elbow will be about 50 deg C or less.

You could well be right Desp my terminology isn't always the best, all I know is the temperature on the direct hot water and heating circuits is turned down to 40 and 35 degrees respectively and if you go near the exhaust when the boilers running its like having a shower with all the water spluttering out and the plume is more like fag smoke or vape mist than the whiter steam vapour you see when the temperature on the boilers is turned up to the max positions. obviously theres some vapour still in the exhaust as its never going to be that efficient but in my head at least I can see a difference in the opacity of the exhaust.

Maybe its a red herring to look at the plume and assume a setting - maybe the proof is standing underneath the exhaust and deciding if you need a brolly or not

Ah well, tomorrow is Big Switch On. Tank swap over has happened today and Iboost is doing its thing. We've switched off the SH's for tonight's charge and looking forward to the inaugural run.

[Fintray]

Good to hear that the switch on is happening tomorrow

Forgot to say earlier that your golden heart ivy might have an adverse reaction to being in the cooled air from the heat pump, we have a crab apple near ours that lost a lot of leaves that were in front of the airstream, though the ivy may be ok

Brilliant news Joe.
Must say what you have posted so far looks great.
That is alot of kit hanging on the wall too.

Ive been waiting for the remedial works to finish before putting up a post about my issues.
Just had an email from certsure saying the companies remedial work of the remedial work, that was done to sort the the original work is also not up to par. So looks like they are coming back for a 4th go at some point and it all cannot be signed off until they are happy.

So whilst its been a slog for you, One extra day wont hurt you to know it is all perfect to begin with!

Aye, that puts in into perspective. I'm so sorry you've hit all these poor installation speedbumps. Can I ask, did you have a particularly low SCOP to signal it wasn't great?

Yes on the adverse effect on the Sulphur heart Iain. Will see how much dies back over the Winter.

There's a man under the floor at 17.45 to finish the pipe insulation.

The Scop has been average. About 4.5. But i put that down to the modulating homely controls i have installed that learn the heating and cooling of the house and constantly adjust the flow temperatures to be optimal.
With such a poor install it should, and would have been much lower.
Its a midea 12kw and their unit is rated for a cop of 3.95.

I knew for looking at the install that it was bad.
Last winter was when all of the heating issues of untightened compression joints were found- by numerous leaks and pressure drops.
They fitted it horrendously.
I did say on here i would do it myself, but what i didnt know was that the solar they had installed was fitted badly too, and that the electrics for both ASHP and solar had been left unsafe, along with internal wall insulation issues.
It was the electrician who came to quote the hybrid inverter install for the batteries that alerted me to the other issues.
And at that point i'd had enough of the BS, wasnt prepated to pay for anything or lift a finger and told them they had to fix it all.

It still is plumbed in plastic under the floor. And i have had to have the buffer that was removed due to their secondary pump seizing last feburary, reinstalled.
As you know this is not optimal, and it will be being changed.
So even after they have finished their remedial work and finally left me with a job up to the minimum standards expected, i will be making changes to maximise the system.
So there will be plenty of time hopefully to compare and contrast each change.
It was all done under the eco scheme. We didnt pay., i suppose we did when we bought the house, but have been plagued with issues and poor workmanship.

Doesn't sound good at all. I don't know what the eco scheme is but I get the point that it was inherited installations. I'm glad to read that you have warranty recourse.

[NoraBatty]

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.
