The 14kW c/w 300L DHW Cyl is £5,710, the copper pipe and fittings to connect both to existing system is around £560, installation labour including electrics test and commission is about £800 plus mark-up is £8,840 ish (just under 9K) radiators (how many) and replace microbore pipe work could be a further £1K on top.... all plus 5% Vat

Yeah I think he is a bit sketchy with his quote, will speak to the folks tomorrow and also the other companies and try get more detail. I was quoted £1250+v just to upgrade the pipes as they are now by another local plumber.

My fourpen'orth. I'd rather have a McDonald Egineers Ecoflow 2000 as it's purpose designed for use with an ASHP. Made in Scotland, though not from girders, I fear. I believe that they'd need plumbing on site though, which he might not want to do..

I'd agree with rhubarbe, the McDonald Eng. Ecoflow 2000 is a good cylinder, however, There's probably about £50 in it....after you price in the extra labour for building it up and for the cost of the circulating pumps, motorised valves, programmer, etc.. all pre-plumbed on the Mitsi cylinder. Both have the large 3m2 primary coil. delivery is included with Mitsi....McDonald Eng. charge £50 although a very good unit and cracking service.

rhubarbe

Isn't the primary coil stainless steel on the Kingspan...? Copper on Ecoflow..

He could go and pick up the Ecoflow - they're only in Fife..

Mitsi were using the Kingspan/Albion Tribune Cylinder.....they are now making their own.... with copper coil.......guess where....?

Livingstone...Scotland with the 8.5kW Ecodan.

rhubarbe

Oh, well, if they are making their own with a 3m2 copper coil and all the bits and bobs bolted on out of the box, and in Scotland, that'll be OK.

Who's going to tell McDonalds?

mitchy74

Youre confusing me now!!

Whats better than what now? Are Ecodans out and something else in?

rhubarbe

No, I'm talking about the hot water cylinder. I used the McDonald Engineers but albyota says that Mitsubishi now make their own...

Just thought I would clarify, just in case, although I think its for another forum, we cannot pin excessive electricity usage to the Altherma system, as for the summer quarter, we did daily meter readings and for the first 17 days, the usage was fine. We would have expected at least 60 units a day to have been used to equal the bill we had. We were using about 12 units. Only the water was on over the summer months.

We know this cant really happen unless someone has tapped into our electricity but our meter has seemed to have jump on/added about 2000 unit per quarter, something that the electricity company say is impossible! The fight continues but the Altherma system is questionable.

Just an update for anyone thats interested there seems to be a fundamental problem with our Altherma, its eat electricity and has been taking excessive amounts to run (unlike anyone else's on our estate) this has baffled the Spaceair engineers who visited this week. Due to the drop in temperature this system is costing us £8.00 per day!!!:mad: And it seem that Spaceair are in no real hurry to help us.

Reading a few forums, Spaceair appear to have a good reputation, other Altherma installers tell a different story it seems that the people who have had trouble with Spaceair dont go on forums:(.

New technology - everyones fine when it work, no one takes responsibility when it doesn't. 2 Years of hell and now probably a legal battle.

I think you need a second opinion from an approved Daikin Altherma Installer. But whether one of them would do it, I have no idea.

But I think if it were me I'd be camped outside Daikin's office jeering at them when they arrived.
