If my gas boiler died today I'd also do a gas one, ASHP just isn't ready to directly replace my combi boiler and costs a boat load more to get.
Yeah it's just not ready yet for anything else but new builds.
The cost would be huuuge!

So its 16p per unit of gas from Jan onwards, ignoring the gov fix. 2.3p added from December, we are changing prices faster. I suppose that could be a positive (if we adjust down faster), from April we slip a bit upwards on the gov fix and then april 2024 we are on our own. Better have a plan by then, a year before it could get much worse then now
If they arent something near to providing the majority of a bill then its not a solution. Seems like no one thing is a perfect fix at present, have more then one viable route. The ideal to me is perfect insulation, whatever the top quality possible is as you just wont need as much energy supply.
The problem is our UK housing stock can't be readily converted into low-energy homes. The only way to do that would be sealing them airtight, which gives different issues with regards to moisture and damp
As long as we’re talking yet-to-be-built new builds. Housing built in the last decade, while well insulated, likely has tiny, plastic piping to similarly small radiators, both of which would likely need changing out, adding cost. Our combi will be replaced with a combi when the time comes, as we’d also need to pay a lot to re-plumb the house to include a hot water tank to reap the benefit of a system boiler, and I’m not sure the cost would be recouped in the lifetime of the boiler including gas savings.Yeah it's just not ready yet for anything else but new builds.

Sounds brutal. Not sure if I'm up to this with historic knee issues. Worked in loft for an hour before and noticed the effect of being hunched.
Would be great if could post if this has been effective

Yea, we have a 2017-build and would needI cannot imagine the cost.
I think in this house at least you'd need
- new windows
- new piping
- new radiators
- remove old boiler
- new ASHP
You'd never get cost back.
Yea, we have a 2017-build and would need
- new piping for whole heating system
- all radiators replaced
- new hot water piping
- new/add in hot water tank
- new/add in ASHP
...if we wanted to go ASHP. We'd just need to change all hot water piping and add in a tank if we wanted to switch to a system boiler.
I think the most cost-effective thing for us would be to just replace our current 35kW combo with a much more appropriately-sized (probably about 28kW) boiler which also modulates down to <2kW for heating load, preferably even lower than 1kW if possible. Our current boiler only drops as low as 7kW so we're taking a big efficiency hit thanks to cycling![]()
My gas DD went from £22 a month to £52 then to £72
I signed into the online account and was offered £51 a month...as if they are doing me a favour?
The Leccy bill is out of control though. I've went from £10 a week (prepay) to £30.
To give 65C it'd be running full-tilt 24/7 and wouldn't manage that in colder outside temperatures, as well as dropping their efficiency to close to 100%, wiping out their advantage and adding unneeded wear and tear.I don't get the issue with ripping all the pipework out, rads being replaced etc
I thought that was long gone, eg you can buy ASHP in screwfix that do upto 65c water.

Samsung 16kW Air-Source Heat Pump Kit 300Ltr - Screwfix
Order online at Screwfix.com. Highly efficient source of heat and hot water, where outside air is blown through a network of tubes filled with R32 refrigerant. This warms up the refrigerant, and it turns from a liquid into a gas. The gas then passes through a compressor, which adds more heat...www.screwfix.com
The issue is more the placement I think. I mean its a big old unit that. Well and the cost of course

Not really a surprise, as gas has almost quadrupled in price. Only person to blame is a certain fascist madman for that one unfortunately.My gas DD went from £22 a month to £52 then to £72
I don't think ASHPs are the answer for most homes. I expect ultimately we'll move over to using hydrogen pumped through the same pipes we're using now for natural gas. Perhaps gradually moving over similar to how they're slowly switching petrol over to biofuel. Worcester already have a domestic style boiler capable of running on either.
I'm pretty chuffed that my December usage with the central heating on was still less than my monthly DD amount (just). I've kept it the same since installing the solar panels so I've built up a bit of a buffer in order to get through winter without going into debt. But based on December, looks like I'm going to stay well within budget.

I'd expect the hydrogen to be produced entirely from zero carbon energy sources. Utilise solar, wind or nuclear outside peak times while demand on the grid is low.We might. Hydrogen will be as expensive as using elec though, at least.
From what I have seen its terribly inefficient (like 3 times more energy input compared to output which will be electricity as the input), will require significant grid infrastructure changes etc

In reality it's so far off - we might even have fusion working by then.
