Nah, I stopped polluting my kitchen 3 years ago. Induction has been absolutely great.

CH boilers don't sit idle for much of the year unless people tend to run a gas central heating boiler and then electric immersion for water? I know a few people with solar do...
Ok cool. Fringe non-issue showstoppers it is then…
Eh? You said CH boilers sit idle for most of the year. That's rubbish.
Mine does, as I have a separate gas fired hot water cylinder. Combi-boiler isn’t man enough for my needs. Plenty of others I’m sure with a similar setup.

Besides, a boiler sitting idle for months is an irrelevance. They’re routinely capable of it, so not sure why you’re trying to make it as a reason why something won’t work. More like what you’re saying is rubbish.

You think plenty of people have two boilers laugh

What extremes? Norway copes, many of our commercial buildings cope.
ASHPs don't cope well when the temperature is near freezing due to evaporator icing.
Perish the thought that the designers might take that into account and include either trace heating or a reverse cycle defrost routine, as have existed in heat pumps used for other purposes for a very long time.

What’s your deal, pal?

I’m discussing hybrid heating systems, and all you’re doing is spouting argumentative, sneering bilge for no apparent reason. Is it because as the self appointed thread know-it-all, no discussions beyond what you deem worthy are permitted?

This isn’t an argument to win as you bizarrely seem determined to make it. It’s a discussion on an alternative retrofit solution to reduce home heating emissions without needing a load of collateral work to make it viable.

Now if you still don’t want to engage in good faith, then do one and find someone else to annoy. HTH

Unbelievable rolleyes

They do have that. But in such conditions, their efficiency goes out the window, and whilst they’re defrosting, they’re not heating, they’re wasting energy. Both of which are problematic when an alternate energy source could take over and operate more effectively.

You want to have a discussion in good faith? Great. So let's stop pretending many people have seperate hot water and heating boilers.

No?

BBC article on the origins of some of the wood being burnt at Drax. https://www.bbc.co.uk/news/science-environment-630... One figure that caught my eye is that Drax has already received £6bn in subsidies.
The picture at the top of the article isn’t Drax though is it? Looks like a foreign power station with the markings on the top of the chimneys and cooling towers. No doubt it’ll be replaced during the day.

Drax has one very tall stack, unpainted.

Yup, steam is invisible biggrin


That report on Drax though… the whole ‘green’ thing is such a load of rubbish.

Chopping down established natural forest full stop is bonkers, but then shipping it from Canada to the UK, then by train (?) then burning it?

The subsidy basically makes it worth while burning diesel to transport it all that way, generating more fossil co2 and wasting diesel.

£6bn to burn natural forests, sawdust, and twisted logs, shipped from Canada.


It makes my head hurt even trying to comprehend the stupidity.
And that it won’t just start and end here, the stupidity will be infested in everything.

Years of easy money and not having to take it seriously have come to a head.
No more bailouts ffs. Let these morons go to the wall.
Spend money on publicly owned stuff… stop giving money to these cretins to run critical infrastructure.

The Beeb has been publishing power stations pictures showing the emission of steam/water vapor clouds for years, usually with a title that has the word 'pollution' in it.

Unsurprisingly, the BBC have now noticed that the Drax article had a picture of another power station & replaced it with the image above. Would look better with your annotations though!

I agree it is bonkers - assuming it's true. When I lived in West Africa there was a company there buying spent rubber trees, chipping them and shipping somewhere as biomass - a British chap running it so very likely going to Drax. Same nonsense with shipping emissions occurred to me, but also the social injustice as wood/charcoal are needed by the local population for cooking.

Closer to home, in NE Scotland straw bales are sometimes trucked down to Drax to be burned. I similarly thought "surely you'd be better off just burning the diesel that the lorries are using", but did some fag packet maths and actually there was method in the apparent madness. For a by-product with very low value that grows within a year, maybe it's a good thing. Even better if stations were less distance away, and better still if nutrients could be recovered from the ash.

I don't think Drax burns much straw, I think it used to though.

Most straw is burnt in Brigg, Ely, Sleaford or Snetterton - best part of 1 million tonnes per annum. This of course pushed up straw value a lot over the last decade. It's a imperfect fuel - easy to handle but difficult for boilers.

Sainsbury's Energy/Eon Next have just sent me the Economy 7 unit rates under the EPG - night rate is one third of the price of day rate (typically it's been 50% up till now) - this translates to it being cheaper for me to bath than shower (stored hot water vs on demand hot water) and cheaper for me to use storage heaters than on demand heating. This will roughly translate into an increase in my energy usage this winter -

Is the cost of generating night rate power really that much lower? Or is there some other game being played to get money out of the tax payer?
