Heat Geek installations: share your experiences

Mars · 2026-10-07T08:59:42Z

We have dedicated forum threads covering many of the UK’s major heat pump installers, so it’s only fitting that we have one for Heat Geek. If you’ve had a Heat Geek installation, please share your experience, good, bad or somewhere in between. We’d particularly like to hear about the design and quotation process, installation quality, disruption, promised and actual performance, flow temperatures, aftercare, performance guarantees and how any problems were resolved. The aim is to build a fair, balanced and useful discussion based on genuine homeowner experiences, helping others make better-informed decisions. Please keep contributions factual and respectful.

@batpred I have a 400% Combined Minimum Performance guarantee: so far today the App is showing 513% with an 8 year old unvented cylinder.

FWiW, I am ‘tracking’, via HeatPump Monitor, a heat pump installation about 10 miles away. The property has the same make and size of heat pump and it is showing an efficiency today of 518% ( this heat pump has consumed about 1kWh more than my heat pump has). From what I can see from the usage pattern they are using weather compensation with a cylinder reheat in the early hours. The HeatPump Monitored annual efficiency is 460%. I don’t know whether any of this is valid but taken together with what I am seeing in the Valliant App I have no reason to think that I have been miss sold on efficiency.
