Any company can tell you how good they claim to be, but we prefer to let our clients do the talking for us. Check out some of the feedback we have had from clients.

Lee, this is just a somewhat belated commendation for excellent service from you personally and McDonald Water Storage generally for dealing with this order. You personally were really helpful in ‘defining’ the order which was very speedily dealt with. The cylinder arrived well and securely packed on its own pallet when you said it would, and I’m really pleased with the quality. It is now installed and working well. I know it is only a pretty standard hot water cylinder, but what I wanted couldn’t be bought ‘off the shelf’ in the quality that I wanted, and you and McDonald Water Storage were able to deliver just what I wanted incredibly speedily. So Well Done – a credit to British Industry.

Bruce, I just thought I’d give you an update. The tank is installed and is working just fine. The plumber is well impressed, he’s been in the business for 30 years and he reckons its a really good piece of kit, well manufactured and very simple to install. I’d like to thank you for your work on making sure we had the correct sized tank and it was delivered on time and to the agreed price. It was refreshing to find someone in sales who has an attitude like yours, working with the customer to accommodate their needs. Many thanks.

Householder, South Yorkshire.


How’s this for express delivery? Ordered a bespoke unvented cylinder by email last night, picking it up at 3pm tomorrow afternoon so that I can get it installed before guests arrive for Christmas. A massive well done to McDonald Water Storage, you are my kind of people!

Now we have a superb hot water supply to sinks and showers without the long expensive wait for the combi boiler to fire up and produce hot water. Also the radiators can now be made hotter than ever before, and that with a 24kW condensing boiler which has replaced a 35kW combi unit.

We are already seeing savings on our metered water consumption since I got the tank commissioned.

Well pleased with my installation and would recommend your thermal stores to anyone looking for a superior hot water supply.

Lee, Many thanks for all your help in getting us a specially-sized CUBEflow Thermal Store. My plumber installed it without any issues at all. It went in as smooth as silk and he was most complimentary about the design. Your support and service to me, at a time of some difficulty,was superb.

Thanks Jamie. As well as McDonald Water Storage having first class products, the response time from you guys is second to none.

Thank you very much indeed for being so helpful and quick. It is greatly appreciated. Wish everyone was the same!

Landlord, Essex


Thanks for the information about the valves on the POWERflow Unvented.  I love you guys already – this is much easier!  Supplying the pressure reducing valve loose, let me fit it under the kitchen sink where the cold mains comes in and meant I got a balanced cold for the whole property!  Having both relief valves pre-fitted to the tundish make a huge difference.  A lot quicker than the stainless steel cylinders I used to fit with my previous company. Can’t wait to install my next one.

Renewable Installer, England

“We should be getting the order on the fact that we can put all connections where the plumber wants them, reducing time on site. He had priced another heat store but the extra work required to use the cheaper stainless one has swung it our way”.
