We do our 20kwh of hot water by immersion using electricity at 8p per unit. Using a heat pump at a cop of 3 would save 389 a year over that or £214 over using gas (perhaps a bit more due to gas not being 100% efficient).
Even if we saved twice that on space heating, 600-700 a year saving has a long payback period when the heat pump would cost 15-16k more than simply replacing the gas boiler....I think....0 -

I thought you were getting a `Dream' heat pump and installing it yourself for a fraction of@silverwhistle
How can it possibly cost £26,500 to install a heat pump at your house?
I thought your net cost from Octopus was £4,000?
If I recall, it's not a huge house?

Currently I have hooked up an ancient second hand Grant HP but it has an issue with a reading from one of the sensors. Am exploring an alternative but much newer second hand unit.
Your comment now made me think about how I connect it. Currently have it teed into a radiator so on 15mm where it meets the central heating circuit but I could do a long run and then tee in to the 22mm.I think....0 -
I remember you had an old Grant connected last year.
Where is it, on your garage roof or somewhere else?0 -

Covers and enclosures do work but I think they need careful design.
A heat pump being visible from the road is no issue at all. As long as the heat pump is no higher than first floor level and it's not a conservation zone or listed building, facing a road is permitted development.
My heat pump is on the front of my house facing the road.
Have you had any advice in regards to planning permission?0 -

Used 90l of water heated from 18.7°C to 44°C and consumed 3.37kWh to do so. This works out to roughly 78.6% efficiency.Boiler is a Viessmann 050, just over a year old, and recently serviced.Her courage will change the world.
Treasure the moments that you have. Savour them for as long as you can for they will never come back again.0 -
