The Heat Pump CON

Electricity is 27p/Kwh. Gas is 6.7p/Kwh.
Even if heat pumps are 400% more efficient (which they aren't) then they are still about equal in cost.
4 x 6.7 = 26.8
So in my simple mind a an air-source heat pump that operates at 200-400% efficiency is never going to be better for me than my current boiler.
My daily Electric is 21Kwh, my daily gas is 63.8Kwh if I convert the gas Kwh into electric Kwh it will cost me more.
63.8 @ 6.8p is less than 63.8 @ 27/4 isn't it?

So why on earth would I change to air source heat pump?
To save the planet and put money in the government's coffers
 
They're quoted as 3+3 so 600% efficient.

Part of the change to lectric heating via air or pipe underground is to make yer heating more efficient in energy use. It's not down to cost directly. In years to come we won't be allowed to burn fossil fuels. Or at least their use will be massively reduced across society so we work towards cleaning up the muck in the air. Where possible we have to work towards using greener fuel and use less ovvit. Like running a fasterer real Freelander wiv 4 cylinders than a big Freelander wiv 8.
The planet will never be clean to Mutch money involved, to many people, to mutch wont wont wont, to Mutch woke woke woke, to Mutch of bending numbers,

I would agree humans can't live wivoot causing damage. We need to live in a way that causes less damage. It seems we're at the pivot point of causing rises in temperature which we won't be able to cope wiv. Peeps refuse to beleive it but we never get 6 inches of snow like we did every year when eye were a nipper.

I think it's already past the point of no return all to do with the mind set and governments how many houses are built today with a garden to grow vegetables look at the savings that can be achieved on one simple thing
 
I had quite a long chat with the offspring and husband about solar panels. Couldn't believe the price of batts if you decide to try and save what you generate rather than pumping it back into the grid. And how short their life is, what a flipping con! :(:(

Our battery bank cost as much as the rest of the system, But we chose that route for a reason.
Friends of ours have been without leccy for 18hrs this week.
And even if you have solar panels and the grid goes down you DONT have electric to use. (is what I am led to believe)
We do.:p

So again its one of those where you pays your money and takes your choice.;)

It's batteries that are the main problem. Storing the electricity that can be made when the sun is shining or the wind is blowing at any scale is still in its infancy. The UK has a handful of pumped storage facilities where water is pumped from a lower reservoir to a higher one when energy is plentiful and allowed to drain to generate electricity when it isn't but we'd need an awful lot more of them to make a dent in the energy needs of the UK. Similarly with individual domestic systems - the batteries are the main element (and represent a substantial environmental burden in their own right). Most fully grid tied systems need the mains to be on to give you any electricity. It is possible to do otherwise, but that's the way most off-the-shelf systems work. I'm the owner of as small solar system myself, but I'm not particularly proud of it from an environmental point of view. The silicon smelting process (to make the solar panels) is not exactly green, as the furnaces need to be run at about 2400 C. There's quite a bit of coal goes into the process (about one part coal to four parts gravel and wood chips), and a good deal of sulphur dioxide, carbon dioxide and possibly arsenic comes out. So the panels will have to last a long, long time (probably over 20 years) to offset the environmental burden involved in creating them. So it's not exactly 'green' to have solar panels! The problems of batteries have been reasonably well rehearsed, but people seem to be keeping very quiet about the problems associated with the panels themselves.

Solar panels are not perfect. Nowt is. But peeps rarely compare to the damage building a power station causes. All that concrete and steal creates polution. Consider that v panels. Eye bet panels shed their pollution within a few years if they're generating reasonable free power.

We dun't need more pumpted storeage. We need to tap oft our reservoirs more. Many are too far from the grid to get cables laid. If the gov chipped in it would hapoen. The grid dun't see the value innit because of cost.

Aye.
I noticed on Saturday when travelling locally past a National Grid installation that they have now installed row upon row of self-contained diesel generator sets over several acres of land. I couldn't stop to take a count of them but they are there all in rows, hundreds of them. I guess they are for when the wind doesn't blow at night, to put all that "Green-energy" into peoples Electric cars. ;)
