Immersun 

We had an Immersun fitted recently. It appears to work well, so I've no complaints about its basic functionality.

But there's a serious caveat. If you want to make use of the Immersun app to control the main unit remotely, that will cost you an extra £199.
No,that's not a typo - £199 to connect your Immersun wirelessly.

Seriously? In 2022?

£199 for a glorified WiFi repeater - which connects to the Immersun wirelessly!!

What a rip-off.

Miles Turner was very helpful during the purchase and dispatch of my Immersun which is now installed and working well.

I had a query on the divert unit actually worked and thus makes best use of my spare PV energy. was explained very clearly and easily.. super simple really.. the CT is measuring the overall flow of electricity.. when it’s flowing back to grid, the divert send excess to a load to balance. top response.

Miles kept me informed at all times after I had ordered an Immersun machine as my copy of an Immersun installed in 2014 by a firm which has since gone bankrupt. Due to chip problems the order which was packed by Miles himself arrived the next day after he said it would. Brilliant.

I ordered an Immersun at the start of the month. I know there's been issues getting chips so didn't expect to get it quickly.
I emailed after a few weeks to get an estimate if when it might arrive. Miles replied promptly and had my order packed up and delivered within the week. Fantastic service. Thank you

My Immersun failed to restart after being turned off and I messaged tech support for advice. I received simple instructions on a solution within a couple of hours and we can now have a bath again! Thank you guys for your excellent support,

Excellent technical support from Anish in the support team. Quick to respond with straightforward solutions / answers to my queries whilst setting up my Immersun.

I reported my Immersun unit was installed in early March 2014 which performed satisfactorily until 23/08/22, the unit no longer appeared to be under power with screen being blank.
I received an email requesting me to send serial number of the unit which should be on the top of the unit, there was no serial number visible anywhere.
At this point I began to get concerned with your company because I registered my unit for the 3 Year Warranty on Friday March 2014 dealing with Richard Barker of Technical Dept. and that you should have this information.
I then received a request to take two images of my unit (front and top), I replied to say yes to this request, but it would take some time because my son would have to take the Images and attach to my email.
In the meantime, I decide to take the front off my unit to see if there was any information inside the unit, I found two printed circuit boards each with a serial number which I copied and emailed to yourselves.
The reply I received was very informative (removing all the confusion that I had and was experiencing), which resulted in the placing an order for a new and updated Immersun Unit. This was over a period of 2/3 weeks without any unpleasantness between the two parties, 24/08/22 to 05/09/22

Many thanks for reassurance, your product knowledge and manner was as good as expected.
But your phone lines need sorting😜!!

I had an issue with my Immersun box so I sent an email through Immersun's website to their Customer Support Department. I received a response back within the hour with clear, concise instructions as how to fix the problem. Great support, thank you Immersun!

Thank you Anish for your prompt and helpful advice. Excellent customer service, after the builder failed to connect up everything correctly. When I get another electrician to complete the job, I hope it will at last all be 100%

Friendly and easy to access support, both over the phone and via email. The Immersun team answered all my questions & were always happy to give advise & recommendations. I really liked the wireless sensor option as the main unit was located upstairs and hence a long way from the mains panel was.

excellent service despite having to deal with an issue that is no longer supported by Immersun. Very helpful with advice and customer interaction. Will have no problem dealing with this company again. Thank you.

Response quick and helplful - Many Thanks

Very useful guidance, thank you.

A mixed experience. The core product is working well, with good support from Anish and other colleagues. But the process of setting up remote access (using the stable live version of the website, not the beta/development version) was slow and rather painful, mainly due to errors and inconsistences in the Immerlink documentation. I have written separately to Immersun with some thoughts for how this could be improved.

I was having a problem with my immersun contacting my Ilink, I was given instructions from the team on what to try but after I followed the instructions it still did not work. I then asked the team to contact me by phone and this they did. After a thorough check through the system it was given the all clear, and I was informed that the problem must lay with the router firewall. When this was turned off the immersun reconnected to the ilink. So thanks Inish, great job!

The team responded promptly to my query and provided an answer which solved the issue. Many thanks

We are installers of Solar PV systems and hot water diverters. We used Immersun for a period of about 6 months and had multiple failures, roughly 20% by my estimation.

It's gotten to the stage not where they will not return emails or phone calls for repair / warranty.

Absolutely dreadful company to deal with.

100% avoid at all costs.

The Eddi is the best of a bad bunch in this product category.

I’m pleased to say the tech support and customer service I received from Immersun for a failed old model unit was second to none. Unfortunately a replacement unit is on its way to me. Thanks all at immersion keep up the great service
