#ClimateDiary We are in intense #Heatpump vs new boiler discussions in our household at the moment, and it is quite something how geopolitics and radiators (and other practicalities like: will the humming be loud?) all swirl through my head at once.

(Our house is old, terraced and high ceilings - it looks like it’s not impossible but challenging. Costs come into it too, of course. Also worried on this front: might geopolitics mean i will not earn any money next few years?)

Narrator: And as the days passed, the seasons turning, year after year, the old house became more and more aware that yes, the humming was loud.
(Yes, I've repeatedly heard people complain about the noise and no I haven't had enough experience with this personally or insight into how this can change from manufacturer to manufacturer)

@pvonhellermannn do you know about https://www.visitaheatpump.com/
We got a heat pump at the end of last summer
Mostly it is quieter than our old gas boiler which had a tendency to vibrate a bit
It sits right by our lounge window, below our bedroom window.
You can hear it if the TV is off and people are being quiet.
During the very cold snap (below freezing) when it was coming on at 4am for cheap rate - it did occasionally wake me up for a minute.
2 new radiators - the rest are from 1980.

@pvonhellermannn oh and I live in a *very* quiet area
Where I used to live in London I would never have been able to hear it over the traffic noise.
Even now it is still quieter than next doors diesel car starting up in the morning.
Not to say people don't ever get annoyed by the noise of heat pumps - just that it's interesting what people do and don't get annoyed by.

@sean @pvonhellermannn One rad upgrade. Heat pump external unit can only be heard if standing right next to it or listening very carefully with a window open and everything else outside is quiet. Lack of rad pipes clanking is the biggest noise reduction over the gas combi!

As I recall, you live in Eastbourne??
If so, then it may be possible to have aquathermic heating, which is a LOT more efficient than air-air heatpumps.
We switched from gas ~5yrs ago and it reduced our KWh consumption to 1/4 of before ... + our old house is now at ~20.5°c for 24hrs a day throughout the winter. No more chilly mornings.
If it's of interest, I'd be v.happy to fill you in on all I know on the subject.

@gsymon thank you! Yes, we are in Eastbourne. I hadn’t even heard of aquathermatic heating - will look into it today!

@pvonhellermannn we had this discussion as well.
Current heatpumps are much quieter than old ones.
We are getting an indoor version. It is the size of a fridge. Outdoors will just be the air ventilation.
I believe it will be as loud as a fridge.Now our neighbours are fine with it.
(We are in an apartment building so had to ask hoa for permission)There are also split heatpumps which will also reduce noise on the outside.
All the best for finding a good solution for your house!

@pvonhellermannn I got one last August. It works well and it's quiet. Needs more room than boiler, and because electricity cost is excessive (due to gas setting the price point) heating bills have stayed about the same.
If you already have solar panels this will help the economics of it substantially, even more so if you have solar + battery. I do not, that's next on my list

@pvonhellermannn I think the anxiety about heat pump noise is very much driven by the fossil fuel lobby
Have you ever heard anyone complain about the noise of air conditioning ?
(air conditioners and heat pumps are the same thing just used in different ways)
This isn't to say I can promise nobody will ever complain about the noise - sounds can trigger very emotional reactions
But it isn't actually about them being loud.

@pvonhellermannn
I got my heatpump because of the Ukraine war. Well, I was wanting one anyway but that made it a lot more obvious how bad oil was for everything and that made me finally do it. I'm in an old terrace too which leaks like crazy. So it isn't cheap to heat but the HP has no problem capacity wise. -

@pvonhellermannn Something people should know before installing an ASHP is that your shower/bath water just won’t be as piping hot anymore. First-world problem, maybe, but a dealbreaker for some.

Can you not also have a hot tank with an immersion heater for the last little bit of heat-boosting? Or does that kind of system intrinsically not have a tank?

@unchartedworlds @pvonhellermannn I can’t see why you couldn’t *add* that, but it wasn’t in the specs we were presented. It might change the calculus for some.

@adamgreenfield @pvonhellermannn mine heats to 55C vs 60C for the gas boiler
60C is painfully hot and always gets mixed down - in fact if you have a mixer tap you wont notice.
So the only real impact is that you need a slightly bigger water tank to store the slightly diluted hot water (if you see what I mean)
We have a legacy solar diverter that sends "excess" solar to the immersion and that does go to 60C on sunny days - I only notice when I'm hand washing dishes and it gets too hot.
