Future home use of Gas Central Heating boiler systems

[MidlandsChap]

Heat pumps use electricity only for circulating the refrigerant - they are basically a fridge working in reverse. They therefore aren't "significantly more expensive to run".

In what way are they more dangerous? Both natural gas and hydrogen will explode if you chuck a match in.

1) Try getting a fridge to cool your house. See how much it costs.
2) No they would not. The flammability range of the gas we have coming into our homes is a fairly constant 10%. The flammability range of hydrogen in your average home environment conditions will be in the range of 40-60%.

An ASHP will manage something like 2-2.5 COP heating hot water under normal conditions.

Potentailly you could produce all your hot water, and a substantial amount of heat using off peak electricity that doesn't cost that much more than gas does.
Also remember by abandoning gas you also avoid the standing charge.

Normal conditions maybe but even thats debatable, but not when its cold/misty which is when its most needed.

With large enough thermal stores, you can produce significantly improved performance by controlling your heat pump to produce as much heat as possible when the temperature outside is highest.
We don't get dropped into -30C deep freezes for long periods in the UK, luckily.

Actually misty is good for heat pumps, because the mist represents substantial amounts of latent heat that will be released if the temperature drops below 0C.
