Grants for heat pumps

Casper55

No I suppose not however it would be more available to people than solar panels, who requrie roof space and southerly orientated roof , not forgetting ten grand to splash out.
P.S I just recieved the phonecall and the estimation for installation was 9.5 grand + extra for increasing the size of the radiators. H emention that this would qualify for a annual payment of around £800 similar to a fit payment starting next october. This will be replacing the exsisting grant system. Your thoughts would be appreciated. Best Regards casper

Hi

Information on proposed RHI scheme in the link provided in post #4 ..... don't know where the guy got the annual payment from as there is no firm information on the domestic level of RHI HP payments yet ... if you get a call back perhaps you can ask where they get their crystal balls from

That had crossed my mind too. Thanks for the reply

JJ, We know you have a heat pump system recently installed, and are very reluctanbt to accept that they have any disadvantages or may not work well at low temperatures.

If thjey are as great as you think, could you tell me why many systems are now 'bi-valent' - i.e. incorporate a separate heating sytem to take over when the heat pump can't manage efficiently? Just to be clear, these bi-valent systems were coming in before the very harsh winter last year - so the only deduction is that even in 'normal' winters, heat pumps stand a reasonable chance of not performing too well and therefore need a backup system.

I'm all electric, so heat pumps could be a good choice for me - but I am considering cheaper and modular air to air heatpumps, and keeping my existing heating system, so I'm pretty pro heatpumps and their use. But I don't blind myself thinking they are not without pretty serious downsides under certain circumstances, and I'm not sure it's fair to other readers to state 'if they are insrtalled correctly, they'll work fine even in the coldest winters', as I think you are saying. At the very least, just looking at the published cop tables, you can see that even the best get very expensive at say -10C - and there are fundamental physical reasons why that is so.

Just to comment on this:
Many heat pumps have a back up system using electric immersion style heaters. On the ones we use, there is a countdown timer, so if the pump is running for say more than 1hr on the heating cycle, then the extra heat will cut in until the return temp is reached. Backup can also be linked to gas or oil heating systems.
Another advantage is if you have a compressor failure, which is rare, you can switch to the alternative heat source.
Over here, we will pay the excess cost if the above has to be used while the unit is under guarantee and has a manufacturing fault, (5 years pump fully inclusive ). Do not know how this would work in the UK though.

Happy to report after winter as promised

Unfortunately or fortunately there did not seem to be any other types of heating systems on the market that would suit given our budget and requirements.

Anyway I have backup heating if it all goes to pot All heating systems have advantages/disadvantages so not wearing rose tinted specs. My personal experience of ASHPs was fine during the last harsh winter but I understand some people had issues. I have no idea who made or what the spec of the systems was and how they were installed and configured, insulation levels etc...

If you are an all electric household you will be astounded at the difference this technology can make to your home.

God I sound like a spammer!

Best wishes

PS I could write volumes on ASHPs but try to say very little about them these days :silenced:

EDIT: Another sunny day so I suppose I should be excited about the PV racking up units

There is an RHI (Renewable Heat Incentive) subsidy of (expected) 8.5 pence per "Deemed Unit" that will come into effect Oct 2012 for ASHP's. The average house is expected to be 10,000 units @8.5p, (£850pa)Index linked, Tax Free, Govt. Guaranteed for 20 years.
Hope that helps

Sounds good, however anyone have any ideas waht a deemed unit is ie BTU or KW or what ever and how would it be measures ie Kw used or kw made & used ie heat generated. Sound like this might not be as straight forward as FIT payments and that caused quite a lot of confusion to some. Best Regards casper

Sorry for bumping an old thread but I got cold called tonight(knock on the door) about these ASHP. Guy was from the next village and was door knocking to drum up some business.

Basically he's pushing these-

http://www.pea.ru/docs/fileadmin/files/NIBE-F2040.pdf

What was interesting was the idea of "FIT" payments starting next year. I was an early adopter with SP's so wondered if these things have dropped in price considerably since this thread was started(bit like SP's) and their efficiency improved to make them a worthwhile alternative to gas.

I've tried to find the specs for energy usage for these, maybe to run one from the solar panels, but can't find any, any thoughts?

Edit:Just found this on the energy saving trust site, seems its only for 7 years,see phase 2

Hiya T. There has been some bad press about ASHP's and NIBE. Article on Rip Off Britain here:

http://www.youtube.com/watch?v=DJr_oPXRYl0

and a BBC News article here:

http://www.bbc.co.uk/news/business-19511637

The news article is quite good as it explains the problem(s) and the importance of getting the sizing right. It also reinforces the golden rule of insulate, insulate, insulate. And explains why these perform well in Sweden as their houses are better built. My brother-in-law lives in Stockholm and their approach to building is much different.

I don't think the criticisms are NIBE specific, more about sizing and heating needs/losses. So a subject that needs a lot of research and specialist advice.

Mart.
