I don’t see solar helping much either. Generation is the peak heating season will be low dec- Feb. Battery storage would be of more utility as the heat pump could run off mains power at night and battery by day. It would have to be on the bigger capacity scale though to cope with heat pump and daily usage.

@P962c Thank you so much for taking the time to share your update, this is great! It was especially helpful to see the photos of your outdoor setup. 👀

Your continued experience living with an ASHP provides such valuable insight for those who are new to heat pumps or thinking about an upgrade!

@meldrewreborn Would you consider a new boiler / heat pump with the schemes that gave you it reduced or free?

My Grandad had a big old chunky boy from the late 80's he switched it out for a new boiler in 2011 (he got it free through a government scheme at the time) he was saving around 1/4 off his bill which was fantastic, however he did need to replace it after around 10yrs as it packed in, whilst he did get a bit of a discount he still had to pay towards it but he says this one is even more efficient than the previous one and is still saving.

He was looking into a heat pump recently however his home was built in the 1800's and it has big thick stone walls so unsure if it would be as efficient. I suppose this is another thing to consider when choosing a replacement 🤔

personally I think the type of building is irrelevant. The boiler doesn’t know what building it’s in, nor does the heat pump - the job of both is to release heat into the home.

if a heat pump can reach a high COP, it can offset the differential between the single tariff prices of gas and electricity. Currently electricity is about 4.5 times the price of gas, but with selective use of TOU tariffs, this differential can be reduced. So it’s entirely possible for the fuel running costs of a heat pump to be lower than a gas boiler - it depends on the various factors.

both will heat a home, but will cost less if the property is well insulated.

I would be willing to investigate any offer that would reduce the capital cost of the installation, and in accounting terms these should be spread over the expected life of the system
and added to the expected running costs.

the cost of fuel isn’t static and the differential between gas and electricity changes over time, sometime due to world wide factors, and sometimes due to government policy.

All in all, these are complex considerations and inevitably depend on assumptions. Sometimes a decision will come down to other factors of importance to the individual.

But if the current system is working fine, I would not be inclined to change it unless the offer was very good.
