@editor @longbyre - Thanks for the heads up with MJS Energy! I have had a helitherm heat pump for nearly 5 years, with an ecocent hotwater system and teh solution has been working really well. Considering electricity is 4-5 times the price of gas, i have been able to spend same as my neighbours do using gas (same size property), plus i get a rebate.

Heliotherm heat pumps are not onyl super quiet (think still quiestest on the market), also where as most heat pumps have an effecienty of 3:1 at 0c, the heliotherm has this at -7c. In my view, you have a made a great choice when it comes to heat pump, stick with it, and hopefully MJS Energy support you. I will also be reaching out to MJS Energy so i can move away from the distributor you were with currently.

@editor The Heliotherm has been commissioned by MJS and has been keeping the house snug and warm. It is very quiet and appears to be efficient. Setting timers and other parameters could be easier, but that's minor.

Thank you to everyone who gave us help and advice. We were getting desperate after being so badly treated and left in the sh1t by ESP (Earth Save Products). Apart from their unprofessional behaviour we have come out as satisfied.

Bottom line?

I have cancer and have had couple of ops. Without the amazing assistance of MJS my recuperation would have been very uncomfortable, in an unheated house, with the stress of an unresolved commissioning. Thank you to MJS!

@longbyre I just came across your thread and you'd stated bring on the cold weather. Was curious to hear how things have gone this winter. Please give us an update.

Update.

I found a partner company for Heliotherm, MJS Energy, based in Powys.

They have been magnificent.

They understood everything. They sent a team to get the installation and commissioning done. They are handling the sign off.

Once you get a reliable engineer and marry them to the Heliotherm.... Magic.

The Heliotherm equipment is very good. Quiet and efficient. Controllable and not totally unpleasing to look at.

Bring on the cold weather

Thanks to Ryan, Andrew and the rest of the great team at MJS Energy

I just spoke with them. My mail of two weeks ago had gone lost.... Some kind asks from my side were met with accusations. They did not want to commit to actually responding to my mail.

Reviews of the company by installers are not good. Many installers in DE and AU no longer ordering with them.

On the wiring diagram, I could not find any in the installation manual.

I hate to say it, but LongByre to me it looks you are on your own now, except some on this forum that will be helping you to get the thing going. Do try to recover your money if possible as suggested by Andehh.

Did you pay for any of it on credit card? Any come back possible there if commissioning was part of it?

That diagram is a good start @longbyre. We do at least now know that we're expecting

mains cables to UFH pump(s) and Heating Controllers
2-core wire from an external temperature sensor
2-core sensor wire (0-10v DC) from the pump between the external unit and the buffer-tank

Once we have a photo showing the inside of the main Control Box, I expect we can make some intuitive decisions of what connects where.

There are a number of different 'standards' for such wiring. So we should also be able to tell a lot by simply looking at a cable.

@derek-m

The wiring is fine between the various units. See the attached drawing "2018 HELIOTHERM... '. However, there are a bunch of cables to terminate in the control panel... That's the bit I do not have yet

@longbyre

A close-up photo of the inside of the control box may be useful.
