Replacing a gas boiler in the UK with a new heat pump would cut emissions by 77-86%

From a broader fact check about heat pumps

Just a heads-up: people on kbin or mbin servers will still see spam comments that I've removed hours ago on slrpnk.net because those platforms don't yet handle federated removals.
They're still way too expensive for most people to afford even with the current financial help available.
If you want to roll these out you'll need to do a government scheme to roll these out for people.
And if you're going to do that, you're better off with a government scheme for free insulation and window glazing. It'll be a much cheaper scheme and still cut CO2 emissions from boiler usage.
I'd argue for the roll out of a government scheme for insulation and a "Lifetime ISA" style financial vehicle where homeowners save some money each month and the government adds 25% into the account up to £1000. That way if you max the contributions, people would be able to afford the cost of a heat pump and installation in 2 to 3 years.
- In a world where we need to get fossil fuel use to zero, we need to provide support for both adding insulation and shifting from a fossil boiler to a heat pump.
- Properly sized heat pumps are nowhere near as expensive as many people think. It's primarily an issue of needed heating capacity bring massively over estimated. Technology Connections has put out a great video recently that goes over it far better than I could, and he has had a similar experience with his parents as I did mine. The HVAC company wanted to replace with a heat pump of the same size as the furnace. A furnace that had at minimum 2.5× the capacity that they actually needed.
I’ve just gone solar and battery, so my next big project is a heat pump. I need to do more research on how much power they use and whether that’s constant or just when it’s trying to heat a whole house, but my end goal is as close to zero cost as possible. Works currently because I’m selling power back to the grid during the day at twice what I pay charging the battery at night. So gas is going to be the main cost sheet this month. Good to see most of the stories about how bad they are are just either misinformed or propaganda…
- Thr better ones use different amounts of power depending on how much heat they're moving. You'll need to read the spec sheet and manual in detail to know exactly how much
- Check out Technology Connection's videos; informative and entertaining
- From my understand, if its 1 phase, its either off or on. 2 phase would have a medium heat setting, which would allow more consistent power draw. And fully variable heat pumps would be even more consistent.
Wow. They should replace that gas boiler asap.
