How would you rate the design, installation and efficiency of your heat pump system? Poll is created on Nov 06, 2022

Flawless – perfect in every sense.

Very pleased and it required 1-2 visits back from the installer to tweak small things.

Generally good, but there were teething issues that we had to address with the installer that should have been done in the first place

Average. On the surface the system was OK, but upon closer inspection it wasn't great and needed a lot more work to get it to perform better.

Poor. The system is expensive to run and doesn't the heat the house adequately.

Absolutely shocking. The installers fitted a system that is not fit for purpose.

[Sticky] Rate the quality of your heat pump design and installation

Mars · 2022-11-06T09:46:29Z

I'm currently engaged in several 'private conversations' with heat pump installers and association members that have taken exception to me stating that less than 20% of heat pump installations in the UK have been flawlessly designed and installed, bringing the competency of installers into question. I believe that most systems are slapped in without much thought for design, especially when retrofitting a heat pump to replace a boiler. This results in systems that don't adequately heat the house and are expensive to run. So I'd like to see how far off the mark I am. Please vote on the poll, and you're welcome to elaborate on your poll selection but leaving a reply below.

@newhouse87 If the room where the bare pipes is a habitable space, then if you are content that it does not become too warm - you have your answer. Regards, Toodles.

@derek-m Hello Derek, Thanks for helping. Pictures here are screen shots showing various setting from the connected App. Drawing a schematic will more challenging but will come onto that a little later

@tp1964

I would suggest that you start a new thread dedicated to your system.

Please provide as much information as possible in relation to your home type and size, heat loss calculations, COP, energy usage, type of controls (thermostats, TRV's etc.) and how the heat pump is being operated.

The installer seems to be gaining some national notoriety. See from 22:50 onwards. https://www.bbc.co.uk/iplayer/episode/m001vnfx/rip-off-britain-series-15-40-my-house-is-a-building-site

And good Lord, I just took a look at their Trust Pilot feedback, wish I hadn't! Some quite distressed individuals.

Just seen from some posts online that this outfit - Greener Living - is apparently closing or have closed. Anyone know any more about this? "UK's number 1 heat pump installer". Judging by their feedback, not a great surprise if it turns out they've fallen... or been pushed!

Or maybe just in the process of changing the company name?

Possibly both. From the sounds of things customers with installation issues are feeling left massively in the lurch & unable to contact them on their office number so there's no sense this is a name change with continuity. Greener Living seems to have gone. Whether they try to start under another name... and take responsibility for all those botched installs under any new name.. remains to be seen.

Not rating my own system but had a visit from a heat geek the other day I asked if he was coming to a new install what heat pumps would he install. He only installs 2 brands Vaillant for a single heat pump and NIBE if you need more than one. Vaillant for level of modulation and control, NIBE because their systems work best when its multiple units.

Anything else he classed as substandard as it was based on manufacturer's transferring air to air software to air to water rather than starting from the beginning hence the lack of modulation.

In saying that any of the 'other' brands would work well enough in a good design but as we all know most aren't.

@gary What factors would be used to ascertain if a system ‘works best’? Factors that come to mind that I can think of include efficiency (COP?) reliability, noise levels, size … what else please? Regards, Toodles.

It was specifically how the 2 units work together in tandem if you look at urban plumbers recent video he installs 2 NIBEs for the first time

@gary And if they install a single unit, what factors influence them then? Toodles.

Logically, addressing hard water issues with a water softening solution seems like common sense ie to preserve good flow rates for an ASHP system, but I’m keen to hear any views from the experts.

Moved in a few years ago, heat pump already installed. Heating bills very high and looking to optimise performance as much as possible (from browsing these forums, my system appears to show many other red flags too!)

thanks
