Thermo dynamics for hot water that runs off atmosphere

[Gavin A]

odd, I thought it was less than that from the report I was looking at the other day, but I was trying to read it off a graph.

so 2.3 million homes heated by electricity...

Your report may be more accurate, the information came from an online Consumer focus report.

If the data is accurate it illustrates the potential market for Thermodynamic Solar Panels.

Gavin, How much does an atypical electrically heated home without gas typically pay per annum in electricity bills?

 

[Gavin A]

I don't know, and don't really have the time to work it out. I'd not be charging £5k for a single panel water heating only system though, and I'm not sure what the cost would be of a full heating system.

A lot of all electric houses probably just have electric showers which would alter things, and most will be on economy 7, which further complicates the calculations.

 

[peteheat]

did the consultants actually take measurements themselves for this report, or attempt to calculate the COP?

Yes they did a full evaluation which did cost a lot of money but nothing even close to trying to defend a case in court from a consumer looking for their money back plus compensation.

Very few if any will save money using the system because there are more issues at large than the warped performance figures.

That said the theory is good and there is a better chance of a return from the larger commercial system however it must be used bivalent instead of the stand alone recommended by the manufacturer.

indeed. I'm wondering if our finances will stretch to buying a unit we can set up to test through this winter.

One of the things that has made me so cross about the whole episode is you should not have to. There should be no Caveat Emptor with regard to this.

 

[peteheat]

My experience of dealing with European manufacturers would frighten most people, they can supply all the test certificates that make the product appear perfect for the job, the truth is many of them are using the customer / supplier as their real world research labs.

Trust none of them if you want to keep your reputation intact.

SolarKing are now advertising and marketing this system. They are advertising for sales staff to sell it via leads generated by door knockers and cold calling...

Thermodynamic water heater system, Heat pump mechanism - AIR MACHT

Looks like thermodynamics without the panel (s). Worth having a look at their online calculator which when I did it for my own house claimed I'd get my money back in 3.9 years....

I am selling gold for £10000 per Kilogram for anyone interested in an alternative investment with a much quicker payback.*(1)

Please note, yet again, Solar King are nothing to do with me or my company Solar Kingdom Ltd. Solar King IS NOT a registered company name. My company SOLAR KINGDOM LTD registered in Scotland. I blog etc as the Solar King. These people are Solarcrown UK Ltd T/A Solarking UK Registered address: Southport Road, Eccleston, Chorley, Lancashire PR7 6E

You may draw your own conclusions as to why I would choose to post this.

With regard to the Air Macht product it is marketed in the UK by Sonnen Macht who are based in Merseyside. I understand there has been some communication between them and MCS over its designation. Found this out when discussing a different product they are marketing called the Zypho. This is a quite interesting looking waste water heat recovery unit that fits under a shower tray.

That's an exhaust air heat pump, been around for a while, Nibe supplied them on a number of new developments, however due to bad design, bad installation and no education of the users, they got really bad press:
NIBE REJECTS BBC VIEW OF EXHAUST AIR HEAT PUMPS - www.nibe.co.uk
BBC News - 'Efficient' heating system left families with big bills

Although I have gracefully bowed out of this discussion. I see no reason why I can not provide real life facts.

A friendly competitor of mine who i was chatting with today, informed me that in the recent cold weather, a system he had been monitoring has taken 7 hours to recover a depleted 200l tank back up to 55 deg C. (from 5 deg C entering)

I got called to look a 16kw ground source pump, time water got to house it was 30 degree, left buffer tank at 40, thou the buffer tank was ony 200 litres.

@SteveK - do you (or he) consider that good or bad?

Do you mind me asking what methodology they used?

Did they test it with varying wind and solar input levels, or just in static air at different air temperatures?

If the latter then I'm not surprised it didn't come out too well.

@SteveK - do you (or he) consider that good or bad?

Bad enough for him to cancel a presentation to his local council he had planned, and pull out of the market.

Me?, I'm a simple refrigeration engineer and I have chosen not to express my opinion on this thread. But I will present real life facts as they become apparent.
