…absolute diamond…head and shoulders…

I was tasked with solving a rather large issue with very little time to spare, Jamie at Immersion Heaters UK Ltd was an absolute diamond. He gave me a very accurate explanation of what i needed to resolve my problem and achieved it in a matter of days. He has product knowledge and went the extra mile to resolve my issue. I rang many companies to resolve this and found he stood head and shoulders above them all. I wouldn’t hesitate to use them again on future projects.

Job well done and I thank you.

…one of those rare, treasured exceptions.

Jamie at Immersion Heaters UK has repeatedly gone out of his way to assist me with advice, information, and selecting heating elements for my microbrewery. He is always patient with answering my questions and making sure I understand. He’s never pushed or rushed me into buying any product; preferring that I make my own informed decision. When he makes suggestions, they are practical and save me hassle and money. I’ve purchased several heating elements since December to replace or upgrade existing ones and I’m extremely pleased with them.

I heartily recommend IHUK to all my brewer friends when they need to replace or upgrade their heating elements. You can trust them and the products they sell. I’m not easily impressed by service or products these days, but this is one of those rare, treasured exceptions.

Very Happy

We are very happy with the immersion elements we’ve purchased from you (2 18KW incoloy elements for use in a brewery setting). They get heavy use, and after 6 years on the one and 1 year on the other they both work as well as the day we installed them. The outer cover gets quite a bit of spray and we’ve never had any water intrusion. Combined with the service we received on ordering, and the price point, we really couldn’t be more happy. Thank you.

…first ferry for France…

Even I’m french and I speak only basic english, Jamie from Immersion Heaters UK didn’t ask me to take my frogs back into the very first ferry for France. At the opposite, he took time to give me the better advice possible and he manage to speak an english understandable for me. Anyway, the products of this company speaks for themselves, and are the best when you want to start, for example, your own brewery. Thanks

Response from the owner5 years ago

Thank you, Florian, for the first review that has made me laugh out loud. French frogs and ferries, indeed! Always happy to help brewers bring pleasure to the masses. And next time I am in Paris, I shall be popping in for a little sample. All the best to everyone at the MICRO BRASSERIE BALTHAZAR.

If you need someone to talk sense Jamie is your man when it comes to immersion heaters Jamie will understand what you require and fit it to spec we went around the houses talking to some of these big companies who have no idea what you need or what you want,we have purchased two heaters since we had the first one custom made.

…rejoice we did!

Sadly we lost contact with Jamie for a few years after he left PHS. But after stumbling across him again rejoice we did!

When it comes to immersion heaters, your problem is his problem. Most other companies just want to take the money and forget about you.

Jamie is knowledgeable, friendly and efficient.

Thanks Jamie!

One of the nicest reviews I have ever received, bought a little tear! Thanks Ian, much obliged.

Great Technical Service

Jamie was a great guy to work with. My customer came to me with the requirement however I wasn’t sure how to help – went to Jamie and he explained what was needed and gave a great technical service.
Have gone back to Jamie since with more enquiries.

Jack Wakefield

Fantastic service and advice from Jamie.

Fantastic service and advice from Jamie – what they don’t have they can get and get made, but the best thing is they can give you advice on your project and help you realise it. As a nano-brewery 10,000 miles away in Australia I can’t fault the service – our heater element delivered with packaging that would survive a missile strike. Jamie helped me with sizing calculations and now shipping micro-p controller with 48 hour turnaround. Finally pricing is very good – compared to Australian suppliers I have saved thousands. Cheers IHUK.

The quality is fantastic and his service goes over and above. highly recommend Jamie and has a wealth of knowledge in this field.

“This was my first contact with this company and I was very impressed.
Their knowledge was excellent and they were able to be flexible to satisfy my particular needs. They went out of their way to arrange a Saturday delivery which saved me from having 2 days without hot water in a milking parlour. I have to say that there are other similar units around which are slightly cheaper but the quality and ease of instalation
of their units make them a winner in my book”

We were designing a large (500 liter) boiler for a brewery and were shopping around for an appropriate heating element. We searched far and wide on the web (globally) for the equipment we needed. We wanted a fast brew and we have very hard water, plus the low pH of our liquid demanded the highest quality materials (all stainless or incaloy); we wanted very high quality at a good price, and we more than found that with the custom 18kw element we ordered from Immersion Heaters UK.
What we also got was fantastic, knowledgeable service. We are very happy we found theses guys, and won’t bother looking at other companies the next time we need a heating element. Thanks again you guys!

Well done Jamie, you deserve to succeed with your can do attitude.

Well what can I say about the service I have received from Jamie, after I managed to beat technology and send an email picture of the part I required, Jamie explained that he could not supply the unit, but he sent my email to a competitor to help me.
Not just here is a phone number get on with it, he knew I was not easy with technology so he did it for me.
Well done Jamie, you deserve to succeed with your can do attitude.
Thank you

Jamie is the man to go to for elements.

We needed an element for our Pilot brewery here in Austria. Jamie at IHUK knew immediately which elements would suit us best. He explained clearly and concisely all our options. It’s not often you find a firm as good as Immersion Heaters UK Ltd and I can wholeheartedly recommend them to anyone. Jamie is the man to go to for elements!

We use them on our process plants that are sent out to Africa.
All the heaters are still going strong after three years of daily use.

Good quality products and excellent customer service.

Superb Knowledge, Advice, Quality & Delivery

Just via a few phone calls with Jamie he provided a industrial immersion heater to suit my needs on very short notice. Highly recommend – I’m not very knowledgeable on immersion heater so I didn’t really know what I wanted other then the fitting size and wattage. With this information Jamie managed to supply a immersion heater and thermostat that we wired and fitted to our equipment and it’s working great. Made my life much easier. Well worth it!

Great advice.

Great advice from Jamie, would have been happy to buy from him but because he was going to be more expensive for the parts I needed, he suggested I sourced the part from somewhere else. He gave me great advice and I would be happy to deal with him in the future. All the best. Thanks for your time.

I would have given you 10 stars if I could.

If every of our suppliers was so patient, friendly and willing to help, then our life would be so much easier. I would have given you 10 stars if I could. I can honestly recommend the company to anyone, however all credit goes to Jamie. He is a guy full of stamina and positive attitude – never in bad mood and always giving 110% to make sure you get what you want. (even if he’s dealing with someone who has no clue what they need – like myself). He saved me hours of research, so I could focus on what I’m good at
Thanks a lot Jamie. It’s been a pleasure dealing with you.

Opening our new brewery…custom elements with a quick turn around…

Opening our new brewery we had to convert from steam to electric, we have two vessels with different heating needs and Jamie was able to build us custom elements with a quick turn around. We were looking for both power, low watt density to avoid charring and ability to easily remove for cleaning and maintenance. They look good and work great!

Rich White

Bespoke service and advice.

Excellent service and advice from Jamie. Our American made Fabric finishing steamer needed a part we couldn’t import or get in this country.

I contacted Jamie at Immersion Heaters UK ltd because of a potential issue with the immersion heater in my domestic hot water tank.

I wasn’t buying, and Jamie wasn’t trying to sell to me … just a straightforward conversation about an issue of reliability, investigating the potential problems and outcomes that might need resolving.

And in a most friendly, helpful and informative way, Jamie addressed all of my questions in just the way you would expect a good and reliable friend to speak with you – straight, honest and sincere.

One of the most refreshing and positive interactions I have had with an organisation in a long time.
