Living in the sticks there are very few shops to shop around, and few folk with whom to haggle.

You mean you haven't got a corner shop selling ASHP's blimey you must be in the middle of nowhere...

There's a lot of companies that are nationwide also check the MCS register for installers in your part of the country..

I got another couple of guys to quote for some heat pumps, still waiting on more actual numbers though.

One of the guys I spoke to semed very knowledgeable, he told me that one of the other companies that quoted me was installing a perfectly ok system (ecodan with kingspan tank) but it was designed in such a way that if we needed to remove a radiator to decorate, the whole system would need to be switched off (so no DHW), and then on refill the system would need to have extra glycol added to it as well as water. He suggested a slight redesign of the cylinder which would enable a radiator to be detached and still get the DHW. DOes this sound right to you? And does the Daikin Altherma system have a similar set up?
Thanks

They are talking rubbish TKM, to remove a radiator to decorate, requires closing both valves either side of the rad, draining the rad, decorate, re-fit rad and top up with water, done! OK you would have to partly fill the radiator with Alpha 11...but only a bit. you would still be able to run the heating and the hot water as normal, I would be concerned if all the rads were removed....!!!

The difference between the Ecodan and the Altherma is, the Ecodan is a contained external unit with a hermetically sealed refrigerant circuit, (very safe) and a hot water cylinder thats it!, whereas the Altherma has a refrigerant circuit (F gas regs apply) between outside unit to the hydrobox (which is the size of a standard wall mounted boiler) then the hot water cylinder. both use R410A, both heat water to 55C.

The pre-plumbed kingspan cylinder is OK, but we prefer to use third party cylinder manufacturer as its less money, this allows us to pass on the savings to the customer.

The Scot Govt interest free loans scheme is closing on 16 June. Only applications received before that will be processed.

I was wondering are there any MCS accredited installers out there willing to install and commission my ASHP , all the pipework is in and the indoor unit(electric boiler) is fully installed and commissioned so as jobs go it should be very straight forward. The thing is to get the grant and possible future incentives I need it to be done by some MCS accredited. I'm in the Midlands area so if anyone is interested please PM me.

Cheers mark.

I plan to get rid of my old combi boiler and install a Mitsu Ecodan and put a new hot water cylinder in a cupboard in the conservatory. Problem is we use the conservatory all the time and I’m concerned that continuous noise of the circulation pumps may irritate. Do the pumps have to be located right next to the cylinder or could they be sited away from it? E.g. In the kitchen where the combi boiler currently sits. The distance from the boiler housing to conservatory cupboard is about 10 feet. No room in Kitchen for the cylinder. The alternative is to put the cylinder in the loft but that would be more costly. Any advice appreciated.

Hi All,

I have spent a lot of time trawling round this forum and am very interested now in getting an ASHP with air conditioning units. I like the sound of the Sanyo ECO CO2 system but I think that is for a system with radiators (please correct me if I'm wrong). So what I want to know is all the units that I would require for outside and inside to heat and provide hot water for a 3 bed detached bungalow so that I can get an idea of the costs involved. At present we just have very inefficient / costly electric storage heaters and immersion heater for hot water.

richardc1983 you seem to have the sort of set-up that we are looking for, would you be able to give me the sort of details I'm needing please?? Also how is your hot water heated?

Many thanks for any responses.
