Very happy with advice i got here on how to optimize my heat pump. I am finished altering settings as recently finished balancing the house to my liking and usage way down compared to my first winter in the house. I am just wondering, would i benefit noticeably from insulating all the copper pipes in my plant room giving that the room is always quite warm anyway.

@newhouse87 One reason for the room always being quite warm is the heat loss from all the pipework I suspect! Regards, Toodles.

Seems any pipework that is leaving the room is insulated so not sure if it would make a a noticeable difference to my bills to insulate the internal pipes. Maybe some day im bored.

@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
