@bontwoody, it's bizarre how established companies just don't care about the quality of their work or bad reviews. Ironically, these guys are training other installers: https://www.thermalearth.co.uk/niceic-training-course

It blows my mind how this can even happen and this got me thinking. There's quite a lot of knowledge we've all accrued on the forums. Anyone want to start an installer training course with me? 🤣 

I may be interested, let me know your ideas.

@editor I do find it bizarre, looking at a companies Trustpilot and Google reviews is one of the first things I check. I can only assume there is so much demand out there that people just take a risk. Im sure Thermal Earth must realise that they have oversized the heatpump, so its not a training issue with them!

@derek-m Do you have something in the pipe-line? 😉 Regards, Toodles.

So the latest is that the company Thermal Earth are refusing to do full handover until the client has paid the bill in full with no guarantees that the 16kW heat pump will work efficiently in warm weather. That includes giving the client the ability to alter the heat pumps settings. I would advise people to say well clear of them.

I suppose your neighbour could conveniently forget to pay the bill until the warmer weather comes along and the systems operation can be assessed.

I will certainly be adding Thermal Earth to the list. Do you think that a toilet roll will be long enough? 😋

@bontwoody in terms of "mild conditions test", its pretty mild now, and by monday its 12C. Can you see what the system is actually running at ?

if it wasn't for the ongoing wars (visible on linkedin and elsewhere) between the various sides of the industry I might be tempted.

@iancalderbank LinkedIn is such a toxic cesspit of narcissists, I gave it 6 months then closed my account. It’s not like I’m looking for another job anyway.

@iancalderbank I didnt see this Ian, what was it you were bringing to my attention?

Latest update on Thermal Earth is they have verbally agreed to provide a written guarantee of performance but still have not managed to give the owner control of her system via the app.

Worryingly the person who was helping me with the Acond, has had a catastrophic failure of his unit after 16 months. So far T.E arent replying to his messages!
