ASHP. We've only gone and done it again!
As some of you know we fitted an ASHP system back in 2009, and let's be generous and say it didn't go too well
Well we're sure some of you will think us insane, and after all the stress that's very possible TBH, but we've just finished the install of pretty much the same system...... but this time by a company that knows what it's doing!
It took a good few letters to the old company, thank you to those who helped, but we eventually got a refund in early 2012 of more than the original purchase price.
Not a profit, as the extra money had been spent many times over in modifications and ridiculous bills, so we eventually ended up about £3k out of pocket when all is added up. We can live with that, it was an education.
This time around there's a marked difference not only in the quality of installation but in the knowledge of the company that carried it out
Now I'm a bit anal about neat pipe work and wiring, but the attention to detail of the installation engineers made my work look untidy, to the point where they actually re did an electric meter mounting to better fit with the scheme.
They also put in the hours, first day - 0800 to 2230 (!), second and third days - 0800 to 1800.
I'm not going to embarrass them by name, the "heat pump guru" and his sidekick (LOL) know it is much appreciated
Misubishi has even supplied and fit it's own monitoring equipment to make sure everything is good this time around. Kudos to them for getting involved. It's a win win deal, they get monitoring data from a holiday home in the frozen north, we get a massive safety net if something goes a bit wonky
It couldn't have worked out better for us.

Re: ASHP. We've only gone and done it again!
It's the little things you look for when you do mainly maintenance tasks such as - how do you check all those expansion vessels?
Looks a good job especially considering the building construction, let's hope it works a treat this time around.Brian - Newton Abbot, Devon, UK

The expansion vessels LOL
I had one split on another system (gas) and it went with quiet a bang. At my fathers house they undersized the vessel and the system vented water every time it got hot and expanded.
We had only a rough idea of the capacity of this system, vessels are very cheap, we estimated we'd need two 24L, then doubled it
Two white ones are from the original 2 x 210L DHW tanks which were replaced with a single 300L, the big blue came with it, so it was fitted along with the two existing white ones.
You can never have too much expansion and they're not exactly taking up space we'd use for anything else...
It's very easy to check them, just slacken the retaining strap and drop it down a bit to access the valve on top. Once a year isn't such a hassle
