Ah yes I remember that episode.
Will have to dig it out and watch again. From memory I think he insulated the mound didn't he. Seems like a good idea if you have the room.

Is anyone selling excess power to the grid or is it just not possible/worth it?
I sell mine using Octopus Outgoing, over the last few months have been getting about 17p per kWh.Octopus SEG has just gone from 3p flatrate to 4.5p.

On the Agile tariff? Which would mean you're still on the Agile incoming too?

No I am on Go for incoming, I know they say they don't allow it but they have.Octopus SEG has just gone from 3p flatrate to 4.5p.
Not sure if any one has linked this yet, on the topic of heat pumps:

I found it interesting, it seems they've come quite far. There's a few follow up videos too on ground source etc.
Super geeky.

I have been looking at R290 air source heat pumps since a poster earlier on suggested it.
R290 seems to be propane.
Why don't all heat pumps use it instead of the ones that only reach 55 degrees. It would seem a no brainer and I can't find a down side currently.
There has to be one otherwise.
When I mentioned it to the chap who is quoting for my system he simply said we can switch to that if you want. When I asked what the downside was he said nothing.
Frustrated I pretty much threw him out after that, but unable to find a reasoned explanantion of why someone would choose the low temp version over the R290 version?

A quick Google suggests that flammability concerns are one drawback. (I suppose that you could also say that about gas boilers ) As far as I can gather they're new so they might be the default choice soon.R290 seems to be propane.

Interesting explanation about heatpumps:

Roger Bisby has been in the building trade for decades, he used to write in 'Professional Builder magazine' back in the 80s/90s so he isn't wet behind the ears.

So basically they work well in many house, but not all. Amazing insight. https://www.youtube.com/watch?v=GhAKMAcmJFg&ab...

Is it interesting because it is in complete alignment with your views?That's normally what people mean when they start a post with the word.
Am I right?
Personally I find new and differing ideas interesting, but each to their own.
I threw down the gauntlet and if you read all of the posts in this thread then I think there is about 2 people who claim to have made it work in a way which applies to the majority of us here in the UK. His video answers many of the points put forward here that I didn't.

Which is where some 90% of us here in the UK happen live. If that's all you took from it then you need to watch it again and open your ears this time.Evoluzione said:

Sorry, having lived in the UK for 30 years before moving out here more recently. I fail to believe that 90% of houses would not be suitable for heat pumps. I'd agree they definitely won't work in all or even most but not sure 90% seems right. Where is this 90% statistic actually from?
I don't think the primary reason for renewable energy is to save money, in fact I don't think it's ever been a reason to adopt it.
Achieving net zero will actually cost, a LOT of money. Those costs are being transferred to consumers so we're all going to pay in one way shape or form and eventually, all of our power will be produced by renewable means. All lovely, and nothing we don't already know.
The idea of being off-grid or 'energy independent' is probably a better way to look at the topic of the thread.
Solar/batteries and heat pumps is the solution for the vast majority.
Other storage solutions are likely to feature in a domestic environment in the future, Hydrogen anyone?

Still asking the wrong question.It can work, you just need an adjustment in attitude and lifestyle.

the actual figure is that 6.9% of our housing was built after 2000. The current wall U value for new builds was only put in in 2013.
Being built after that year doesn't mean they're up to heat pump spec either, far from it.
From here: https://en.wikipedia.org/wiki/Housing_in_the_Unite...
"British homes are some of the most expensive to heat in Europe, which results in high levels of fuel poverty (for further information see Fuel poverty in the United Kingdom).[93] The problem results from age of the housing stock with most dwellings being built prior to oil shock of 1973, after which insulation standards for newly build housing improved. British dwellings have the oldest age profile in the EU with over 60% being built before 1960, and with only just over 10% being built between 1991-2010."

Exactly this. Which is what I wrote in my opening post.Achieving net zero will actually cost, a LOT of money. Those costs are being transferred to consumers so we're all going to pay in one way shape or form and eventually, all of our power will be produced by renewable means. All lovely, and nothing we don't already know.
The problem is here (on PH) and in real life people are asking the same questions over and over again and all they want is to see a saving. That's what this thread is for.
