Are ASHP the way to go?

You are missing a vital part of the next phase of your heat pump ownership. It goes in the red circle.

@matt_drummer looks like a neat install.

Were the installers local or Octopus branded?

I think it's pretty neat.

It's quite a tight space although it looked much tighter than it actually was with the old system. Of course, I knew it would be big enough

The installers were all Octopus employees. The lead installer was from Gloucester and had five nights in a local hotel.

The other three were from within around a mile radius of here.

That's really good to hear if they have their own lead installers to sign everything off they can keep the quality high.

What is the white cylinder top right "...ukin"?  I thought it might be a buffer but it doesn't seem to have enough connections.

The brand is Daikin and I think the silver label says "volumiser"?

It is a World Heat volumiser with a Dakin sticker on it. made in Manchester!

A very neat installation save for one thing that would concern me. The guidance that I have read from Daikin and others is that the storage cylinder etc should be in a ventilated space. I can see what looks like a very expensive controller on the cupboard side wall. Last year when we had the very high ambient temperatures my hot water programmer failed. A quick check revealed that the temperature inside of my airing cupboard was well in excess of 40C. The approved operating temperature for the controller was only 0 to 35C.

Thanks for the heads up.

I does have some ventilation above the cupboard.

It's also much cooler in there than it was with the old heating/hot water system. I'm sure the heat loss is much lower now. it's very well insulated.

I didn't know that it could be an issue but I have one saving grace, it's guaranteed up to the hilt by Octopus, if there is one company I won't have a problem with I think it is them.

I actually have a second saving grace that I cant really mention, but I can keep the room cool enough

I made a mistake in my post, the other three were from around a 50 mile radius, not a mile!

Sorry.

The chair or stool that you sit on for the next year playing with your new toy🤣🤣

matt_drummer

It's actually already there.

My drum kit lives in there so all I have to do is spin around when I want to admire it!

If you have a volumiser you must also have a means of ensuring that there is flow, even in the scenario that your room thermostat calls for heat when the TRVs on all your radiators are closed.  If you have more than one heating zone that requirement must apply to every zone.  The usual central heating solution is to have an Automatic Bypass Valve; do you have one of those somewhere?  A lot of heat pump installations use a buffer tank instead of a volumiser.  The buffer removes the need for an automatic bypass valve but I don't know the reasons why a buffer might be preferred to a volumiser (any cost saving is minimal).
