Sorry, from my two year experience with Heat Pump installers , the workforce consists of competent Plumbers and Electricians with no Low Temperature experience, often arriving  on site with neither manuals nor Spare parts.

Sorry, but you WILL have to  become a Heat Geek knowing far more than any installer.!

You will need:

1) Temperature Data logger to  record the Outages that will occur during Winter nights.!

2) Set of manuals for your Heat Pump.

3) A Temperature meter with a set of K Type pipe clamps.

Good luck. Welcome to reality

@heliohelp I think you've been very unlucky there, both in choice of installer, and choice of heat pump OEM. The Heliotherm looks a quality product, especially the controls, but if their UK customer support is lacking or non-existent, that's of little comfort. It's not a common product in the UK, so persons with product competency and knowledge will be few and far between. UK installers and service engineers need good support from the OEMs as well, or they will vote with their feet and work for or represent other OEMs.

You'll have probably come across this post thread about issues with EPS and how MJS seem to have stepped up to the plate and helped someone else out? https://renewableheatinghub.co.uk/forums/postid/20853

Some of the big names in the UK energy industry are now offering heat pump installation, or packages including ASHPs and bespoke tariffs. I think their reputations are on the line if they don't honour their part of the deal with reputable products backed by prompt, timely and affordable post-installation support. All A2W ASHPs do the same thing - heat water using energy from ambient air using a simple process of refrigerant evaporation, but the system design and install quality can vary hugely - that's usually where the problems arise.

@allyfish Thanks for the commiserations. Yes we became aware of the troubles with ESP that were sorted by MJS but by then our installation had been completed and commissioned. We have been in touch with MJS but to date they have been shy of offering advice. We also have contact with another 'competent' person but he is not in a position to help without access to spare parts!

@heliohelp in light of this topic, I’ve just received an email from MJS asking you to contact them. I’ve sent you the email address.

@editor Thanks Mars, we have emailed and copied you in.

@heliohelp great. Let me know if anything useful transpires.

I started, with the best of intentions,  trying to " save the environment" on Valentines day 2022.

My "Installer" has been STUCK-OFF three times during the last two years, with the NIC saying that my "installer" has been subjected to severe extra unspecified 'Sanctions' to no effect, and that , consequently " nothing can now be done".

I Do not want to become a "crabbit Auld Man" but have lost all confidence in the competence of the "Charities the NIC and MCS.

My former "Green Energy supplier", Shell, has also shown it's true colours when abandoning it's Home Energy outlet.

Many thanks for your Well written ,excellent, script, telling my story over the last Two years.

Thought it was time for an update with our quest for a working relationship with an organisation able to maintain and service our Heliotherm.

We are pleased to report that we finally established contact with MJS Energy (perhaps some thanks due to Mars). Following a welcome visit by an MJS engineer in early March we are now awaiting a report on the state of our installation together with recommendations for fixes and arrangements for providing the support and service we feel we need. The engineer who came was in tune with where we wanted to get to in terms of being able to understand and monitor our heating system. He was happy to spend time going over the issues we had faced and displayed his knowledge of the equipment and perhaps more importantly undertook to find and provide answers to our queries where he could not. He also spent time explaining the use of the web control facility and restored notification of ‘errors’ to our mobile and laptop.

Pending the report and formulation of maintenance and support arrangements we are now much more confident of how we would deal with a further failure of the nature we experienced previously. Finally, although it was a mild winter we fully appreciated the investment we made in making sure our home was insulated to a high standard before embarking on the Air Source Heat Pump journey …..... more to follow?

@heliohelp thanks for the update and glad MJS Energy came out to see you. Keep us posted on what happens next.

@Mars

My Heat Pump was "designed" to supply Water at 50 C.

My Radiators were selected to supply 2.2 Kw at 50C !

My Water Temperature at the Radiators , is Actually between 36C  to 39 C.

My Radiators Actually supply 36/50  or 72% of their "designed"  power .

I am , now, a 76 year old OAP , now broke & cold after two years of trying to help the Environment !

NIC refuse to allow permission for "Any recording device , or TV Camera "

To Check Or Not to Check?

Following my last visit by my , now former , "installer " I was offered a repair or upgrade to my Heat Pump

IF, BUT  ONLY IF

I Agree to the removal of All Measuring devices .

Needless to say I Refused!.

During this last visit the NIC Engineer also stated that 

"Metering is NOT Required, or allowed,  following the removal of RHI !."

I Again, refused to remove my metering!

The NIC engineer and my "installer" then "Adjusted " my Samsung Heat Pump ................ensuring complete Heat Pump failure !

I was left to remove the "Adjustments " myself !

The  "Engineering" Trio  then fled the scene, leaving me to get the heat pump working!
