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... Toon meer

A company with a strong aftersales and help ethos.

J'ai un immersun t 1060 depuis 4ans mais j'ai eu le malheur d'utiliser le boost. La carte électronique a bruler. Je trouve que ce n'est pas normal que cela arrive quant on l'utilise correctement.
J'habite en france alors je demanderai simplement de faire fonctionner la garantie en me renvoyant une carte électronique neuve.
500€ pour 4ans, c'est pas rentable. Dans ces conditions, je déconseille d'acheter cet appareil.

The greatest test is when things go wrong... and how they are put right!
In my opinion, the greatest test of a company is when things go wrong - how they react and resolve problems and how long this takes.
I purchased an Immersun unit which turned out to have a fault under certain loads.
Communication was great, we worked through some tests but couldn't resolve it this way.
My return was arranged and the fault on my unit was resolved promptly (1 week after it was collected).
There has always been a fast response to my ticket. I could guarantee I would have a reply within a day or less every time.
Thank you, Immersun for the excellent after-sales service, this is my second Immersum unit in 6 years, and not only will I be back again in future, but I will be recommending you and your excellent after-sales support!

Excellent support via chat on website today.
I have had issues with Immersun in the past (faulty equipment and bad customer support) but today I used online support via 'chat' because our Immersun stopped working after a power cut and the help I received was excellent.

Top drawer and super responsive support…
Top drawer and responsive online chat and email help. Very clear instructions provided and Diverter issues resolved.
An additional query submitted online was answered by a telephone call back. How's that for excellent customer service and where else do you get that nowadays. Superb company thank you Anish. Customer for life.

Have an old unit that was fitted before…
Have an old unit that was fitted before the original company went bust. Several times when i needed support the new owners claimed that they are only supporting the older units out of goodwill and they have no responsibility or obligation to the original owners. Twice they even tried to claim that they are unreliable, catch fire and (surprise, surprise) i should purchase one of their new ones. When i mentioned trading standards and if they now own the intellectual property, i was quickly cut off the app and all communication stopped. Pathetic, will be swappping it for the much better myenergy Eddi very soon.

Clear well written advice
I had an issue with my Immersun units connectivity to the internet
Having raised the problem I received a comprehensive replay from the support team suggesting potential cures. I worked through the suggestion and very quickly solved the problem.
Excellent support, thank you!

Great and speedy service from Anish and the team.
The Immersun was collected, repaired and returned quickly. Excellent customer service, thank you Anish and the team.
Just got to clear installation with my electrician ....
At this stage I am still considering whether to order a replacement for my old Eco Immersun. So far the help and advice from (new!) Immersun I've had has been given very quickly. I merely, now, need to speak to my electrician concerning installation. If he's happy, I'll certainly be going ahead. Thanks Fellahs!
Five star support from Anish.
Five star support from Anish.
Fast, courteous , simple, worked.
Great support
Even though I bought this immersun unit way before the present company took control they have provided an excellent after sales support each time I have needed them.
Well done Anish and the team.
Bad Product and Customer help
I am a contractor; they sold the product we installed it and they are trying to find everything they can to get out of replacing it.
The customer has no hot water, and they are the ones feeling it.
Why are their products out there if they have a design fault.

Well worth it
Bought the original version (made by eco4 who sold company brand and product to current manufacturers)...in 2014. Still going strong and infact have now re-established the immerlink functionality courtesy of the very helpful help desk. Works a treat
