Heat pump experiences

[presta]

Spark gap is the ratio of electricity price to gas price.

My boiler service engineer called today and he tells me he has moved recently to a new address and this one has a heat pump. He tells me it heats the hot water beautifully but hasn’t yet had to use the heating facility yet. I will keep you posted on his findings in due course.

To complicate matters, my house has solid wall upstairs and cavity wall downstairs.

Was the architect perverse or something?

Get a Daikins as a Joule may leak on you or rattle.

Went to the city centre today and to the Octopus Energy display. I wanted to know about selling my surplus electricity my Tesla Powerwall produces to them but sadly all they wanted to do was sell me a heat pump. I walked off.

Any Update???

Any Update???

Not yet, he hasn’t turned the heating on yet but the heat pump works well with his domestic hot water demands.

As far as heat pumps go
our main concern is 2 fold
a) I don;t think the insulation in our walls is good enough
and I do not know how to check - or for that matter upgrade it without massive work
b) we do not like the whole house to be the same temperature - we lik ethe bedroom to be cool and the lounge to be warm
and heat pumps seem to want to make the whole place the same

You can and probably should get a heat loss survey done. There's no such thing as not good enough for a heat pump: they're already used to heat barely-insulated DIY big box stores, after all. But the size of pump you'd need might be uneconomical or difficult to find a place for.

As a minimum, a decent insulation company will probably come out, check your insulation by drilling holes in the walls and quote for upgrades. No sense ruling it out before asking experts.

No, that's down to what size radiators you put in each room, how they're balanced, and the insulation between them. Ours can temporarily hold the living room three degrees warmer than the rest, but there's not really insulation between them so once the heating stops, it'll level out before long.

Thanks - useful ideas when the current boiler gets older!

How much would one cost?

I'm looking at £1700 for a new boiler.

With a grant would I be able to get one for similar money?

3 bed semi?

It's possible, as there are even examples of people paying less than that gas boiler, once the Boiler Upgrade Scheme grant is deducted - but the devil's in the detail and a lot is decided by how well the last heating system was designed. "3 bed semi" ain't enough details.

Unfortunately, some UK homes seem to have not had heating systems designed so much as wanged in and keep fitting larger more powerful boilers until it works, based on the Great British saying "pigs can fly if enough fuel is put into them". More profit for the installer, more profit for the boiler manufacturer, more profit for the gas companies, only the residents lose = trebles all round!

It's a thirties house with dirty cavity.

Roof space should be insulated as it's been recently converted.

I'll probably just go for new boiler tbh.

Even if you're not convinced by the sustainability argument, you might as well ask for estimates from some heat pump installers, unless where you're putting the new boiler is well-isolated from the living space or you don't care about the health of anyone who lives there.

 

[ebikeerwidnes]

do any installers give a guarantee about the savings

or at least no increases

the article that you see either say you will save LOADS
or are horror stories about people who are no paying loads more than they were before

which is just confusing
