Seriously? Better put me there too, we have a multi fuel stove. We burn a bag of coal in roughly a month in winter. But we also run electric cars, have solar panels and a home battery. And I hardly think that a hobby of building steam engines is going to destroy the planet. It would probably only run once a year.

I've also got a stove. But I hardly use it since I fitted a heat pump last year. Once I've finished the current wood pile I doubt I'll bother replenishing it.
It's not the individual actions that I object to, it's the fingers in ears attitude that refuses to acknowledge that we need to reduce fossil fuel consumption.

...that other people have other opinions, and they're entitled to them.

I have various sorts of stoves and heating devices. Some I use rather a lot; some I use no longer.
But the one thing I'm intolerant of is others' intolerance.

We have a fairly large pile of 160 year old bricks. An air source heat pump would never cope. A ground source might, but that’s 50 grand I’ll never see again.

Well when that opinion is at odds with reality, no, I can't be bothered to engage.

And I've got a drafty bungalow on a hill in the north of Scotland.
Your heating system doesn't know what kind of house it's in.
Have you considered air-to-air? I'm very happy with mine.

The draughts are your own fault. That’s a genuine waste of resources. We have none. But do have 4500 sq ft to heat. Our gas boiler is 33kw. I’ve seen a 19Kw air source, but no bigger.

I dont use any heating, apart from when I have a shower.
I am both olier an arder than thou
but not necessarily appier
and probably quite a lot colder

The drafts are primarily the fault of the construction method. I'd have to take every wall back to the blockwork to do anything about it, nectar there's a 1" void behind the plasterboard. In some rooms I've done that before I was doing other renovations. It's a work in progress.
The suspended t&g floor is a good source of drafts too. I improved that a lot when I fitted laminate, but the worst drafts are around the perimeter and you have to leave a gap there.

Despite the terrible construction, my heat pump does a great job of keeping the place toasty warm.

An A2WHP normally runs longer and cooler than a gas boiler. Does your 33kw boiler run flat out all day? Probably not. That's why ASHPs are generally smaller.

There are all sorts of neat solutions though. E.g. you could have a A2WHP doing your hot water and background UFH, with A2A topping up the heat as required.

The latest A2A can have an efficiency of over 500%.

I'm not trying to tell anybody how to do things, but sometimes this discussion is reminiscent of the AWB/MAB debate. New technology appears and not everybody makes the effort to fully understand it. Unfortunately when it comes to emissions, we don't all live in bubbles and our actions do affect others.

I have an ASHP heating a pile of 200 year old stones and it is fine. A building is heat source agnostic, it doesn't know or care where the heat comes from, it only needs enough heat to match the heat loss. Your heating bills will be higher, like mine, whatever the source, because we have old buildings with poor insulation. But the idea that a ASHP can't cope with this sort of building is an urban myth.

Drafts can be very hard to fix in old buildings, especially if listed. The other problem is the walls, they tend to have high heat losses and no I am not going to ruin the aesthetics with layers of insulation.

Your house may be on the large side but gas boilers historically were over-sized, doesn't tell you much about actual heat loss. If you do have an exceptionally high heat loss, you just fit two ASHPs.

By the way, if you have historical records of your gas consumption, you can get a crude estimate of your heat loss. But you have to be aware you will run a heat pump differently, low and steady, on all (or most of) the time, whereas gas (and oil) tend to be timed, and fast and furious when they are on.

But why are we discussing heat pumps here, when there is an excellent forum for such things here.
 
I don't think I will live long enough to get payback on the investment needed to heat our listed pile. The restrictions on improvement needed to achieve better environmental gains leave me thinking it's never going to happen, and my personal efforts are not going to change the world.

If you are listed, you can get exemptions from some of the things you might otherwise be required to do. One of the rare cases when being listed is useful.

There are grants you can use to help fund an ASHP. Not the full amount, but not a drop in the ocean either.

I burn several hundred litres of heating oil and many cubic meters of firewood not to mention a quantity of aviation fuel flying to sunnier climes in order to keep myself warm each winter.

May I go on the list too please?
