Thermo dynamics for hot water that runs off atmosphere

[Danlow84]

Dont see why all the negativity and childish comments on here?We have never tried to force anyone to get involved in solar or thermo if it isnt going to benefit them we just give people the facts with free survey just so people can have the facts and figures to read in there own time.

Can Thermo dynamics provide enough energy for space heating

Can Thermo dynamics provide enough energy for space heating

that's a bit of a trick question.

They produce heat at something like 4-600W IIRC, so could feasibly be used for heating in passif house type situations with extremely low heat requirements. They're pretty similar to exhaust air heat pumps in that respect.

They would require an immersion back up as they cut out at something like -10 / -15, but so do many ASHPs.

There's probably only around 0.001% of the UK housing stock that'd have those low levels of heating demand / high insulation levels though, so they're not suitable for retrofitting, but could be a good option if the UK is serious about new builds moving to being extremely low energy using houses.

Of course it also depends on how many are fitted, and I've never really seen proper trade prices for the multiple panel heating units energie offer / have pictures being used, so it's hard to judge the financial viability of such systems vs ASHP / GSHP / EAHP options.

I'm firmly in the camp of more info needed, but I really like the potential of the product IF specified for suitable situations.

I've started to look into this technology. I would be interested in know how they would perform in hard weather up here in Scotland. Personally I'm sceptical of the claims that they perform in all weathers 24/7. How can that be when even the best heat pumps (which these are) require defrost cycles.

Oh and just thought I would mention there are a few companies selling units like this up here. Customer of mine had a quote for £22K.!! and was guaranteed the RHI. Some people have no shame.

 

[Danlow84]

No way would i pay 22k the single panel system starts at about 5k and your right they stop working if temp drops below -15 but apart from that they do work day and nite in any weather condition would be happy to give you more information if required

trading standards job that IMO.

True gavin just because not a lot of people havr heard about them some companiea think they can charge the world

Do they work at full output down to -15 and cut off, or start degrading from 0 or higher?

 

[jason121]

So if MCS class them has a heat pump, they won’t be eligible for the RHI because they cannot be used for space heating

 

[Danlow84]

They work at full output down to -15.If anyone is interested in a free survey no obligation please feel free to inbox me

I think I am about to loose the will to live with regard to this technology.
PLEASE someone provide real life, substantiated performance data for this equipment. Otherwise this is nothing but mental masturbation. In may make you feel good but it doesn't produce anything. What is so difficult about this? I have been asking for over a year without success.
Come on, show us the colour of your money.
This must be the fourth thread on this topic, still with no conclusion.

 

[Danlow84]

If youve been trying for over a year could you not just talk to someone who has it fitted?if you tell me exactly what it is your looking for i will gladly try and help

 

[Earthstore]

Hmmm, £5000 to install a system that just heats your hot water, that is without the running costs.
Just how much do you think it costs to heat hot water in a domestic situation using standard methods?

By the way I have looked into these systems myself, but for heating not just hot water.
I am not saying they do not work, just as the rest of the industry is saying, there is still no proven real time data for them yet.

 

[jason121]

i am still waiting for my answer from you Danlow84

 

[Danlow84]

What was your question jason?and i think if you were to have constant hot water 24 hours a day your gas bills would be very very high and as you may be aware they can also be used to constantly heat things like swimming pools aswell

 

[jason121]

So if MCS class them has a heat pump, they won’t be eligible for the RHI because they cannot be used for space heating yes or no ?

 

[Danlow84]

At the minute that is true they aint eligable for rhi but a lot of ppl in idustry are confident by march time they will be

 

[jason121]

not if they class them as a heat pump which in effect they are

 

[Vegelen]

They work in all weather conditions.
They work at full output down to -15C.
Fast, payback period.

No, no and no.

3 Strikes and you're out?
