No real alternatives to fossil fuels ..

viessmann some years ago were in some partnership with some house builder who were building a house in the UK heated by ice

down this way some where

heard nowt about it since ?

there is a big lake source system coming on stream down here in the next few weeks

personally I think it will prove to be a bit of a turkey ???

I know ice takes up and gives up a lot of energy to freeze and thaw, but beyond that....?

that was my take on the article i read

thawing and re freezing created the energy to heat the house ?? but have heard no more about the project

A lot of projects never get beyond the theory stage, some projects are just projects to attract financial backing from the gullible investers , then the fizzle quietly out.

I find that 20deg C is a comfortable temp for my living environment.

Physics, mathematics & economics plays a large part in how I can maintain that environment.

I'm not a physicist & I'm not an enviroMENTAList.

I don't give a flying f~~K about your MSM telling me how I can achieve a comfortable temp in my house !

Open them back up and send all the doleys down, along with the prison population. Reduction in sentences linked to production quotas.
 
"" Air Sourced Heat Pumps will warm the homes and at the same time cool the environment reversing climate change. ""

The author of that factually accurate statement declines to say what will happen to the electrical energy used to power the heat pump.

If the homes are warmer than the environment then the homes will be heating the environment. That is unless we all live in homes with no heat loss. This zero loss could be achieved by all homes being built like thermos flasks. But these heat tight homes would need heat pumps to pump the occupant's body heat out to prevent occupants cooking in their own heat.

I heard about it several days ago and the mention of the £5K bribe. As you suggest - it will not make any difference to the environment temperature sucking heat from the outdoors and pumping it into the house, because the heat will all escape back out again, so no net gain or loss. That is apart from the waste heat generated by the actual heat pump equipment. 1Kw in equals possibly around 3kw low level heat out.

Its unusually mild outside at the moment - it is 14.5C at 8am. In here it is a comfortable 19.9C, with absolutely no boiler heat input since last evening and almost no other power being used, which supports my claim that we are pretty well insulated.

MOD has been managing nuclear reactors for decades and the Old Naval College Greenwich had a mini reactor for research and training purposes for many years. These could be installed nationwide to add to the UK energy mix relatively quickly.

And have been having trouble training and keeping engineers to maintain them.

Submarine nuclear plants are extortionately expensive, hard to maintain, have a fraction of the redundancy in a civilian plant and I believe use enriched nuclear fuel. Which isn't a dirty bomb risk, it's a nuclear weapon risk. Thankfully they are guarded by 80 odd naval officers and ratings all hours of the day.

The idea of a small, civilian grade, nuclear reactor has been looked at a lot ever since the 1950s. That's exactly what the SMR concept is all about. They're not going to be ready before 2030.

After that they might be able to be churned out in just 5 years each, but the nuclear industry has promised a lot over the years.
 
Talking about this today on BBC News. One guy spent £20000 installing ground source heat pumps and solar. That's £166 a month over 10 years. Great if it never needs replacing and you live to enjoy it, but bloody expensive otherwise.

Not much good for anybody without a "huge garden" though. That's most people.
 
We choose ( searched for ) a plot of land with a stream with the intention of a water sourced heat pump. That was the late 1970's. The theory based on data from the Philips Experimental House team (*) suggested that it would only be cost effective if gas was not available to the site. The practicalities of installing the system suggested that it could not be a low cost installation when the legalities of management of refrigerant gases were taken into account..

After managing to convince the gas supplier to add our site and 6 other houses to the gas network the heat pump project for the house was dropped.

That said for some projects water sourced can be very effective.

(*) Primarily the house at Aachen was designed as a passive house but the heating of existing housing stock was also investigated.
