McDonald Water Storage Opiniones 

10yr from first vented tank before catastrophic failure, five years from its replacement. Both failed at welds, the second clearly due to manufacturing defect.

Was offered a reduced price replacement despite being told that five years was a reasonable lifespan by both the sales team and later a company director.
I wouldn’t install a tank made by this company if you paid me.
Frustrating

Edit:
A clear photo was sent plainly showing a section of bad welding on the exterior of the tank and under the insulation. The determined cause WAS verified by the production team who indicated that the tank was irreparable.
Strict 5yr warranty indicates exactly how much trust they have in their products. A typical unvented copper cylinder should be reasonably expected to last an average of 20 years.

Excellent service from the start. Highly recommended.

Top company always reliable.

First class service, great communication with excellent quality item and reliable delivery, would not hesitate to use again

From start to finish, a joy to deal with. Had a custom hot water tank made by them. Quick email response and great delivery service. Will definitely use again.

Having been badly let down by another firm I contacted McDonalds and explained my requirements and urgency.
Tiff was very helpful and got a drawing to me straight away for confirmation. Order was taken and delivery date brought forward to suit my needs. Cylinder delivered on the promised date, very securely packaged. Could not have been a better experience.

Very easy to order, kept you up to date with progress and delivery was smooth.

Cannot fault the service received. Purchased a replacement tank - this was constructed swiftly, communication was prompt. Team always on hand to speak whether via email or phone. Delivery was arranged and rearranged at short notice with no issues. Would highly recommend.

Great company to deal with. I bought a Cubeflow 150L in 2018 and needed a spare part in 2025. Superfast delivery and the guys in the office are always on hand to answer technical questions.

Thank you McDonald for making the ordering and delivery of a replacement hot storage tank easy. You worked with the dimensions we had and gave us an extra 50l of capacity in the same space. And the product leadtime was accurate and delivered without drama.

McDonalds made a bespoke replacement for me using measurements I had taken from the old cylinder. Such was the match to the old unit,I was able to re use with a few straight couplers and a tweek or 2 with the bender, nearly all the 28mm copper flow and returns, from 2 boilers,that I had to remove to get the the old cylinder out of the cupboard . Took 2 days to fit and finish, all back to normal service again now. So thankyou McDonald's. So glad I found you. G.D.

when I ordered a copper header tank, though I had missed the next day deceiver time slot, they still managed to get it to me next day. Brilliant service.

Since buying a 120 litre thermal tank from McDonalds for my flat this summer, I have needed to get a temperature gauge and have this sent to me as quickly as possible. To cut a long story short, since living in the Highlands, their APS courier would have taken up to 3 or 4 days to get the gauge to me. The ladies, Sara and Rachael, in accounts & admin, ensured that I would receive the item the very next day as they went beyond their call of duty to have it sent by Royal Mail signed for. Brilliant. I did not expect this level of service but very grateful for it. A truly reliable, decent company with very caring and attentive staff. From my first phone call to them in April 2025 when in the process of buying a thermal tank, I have been met with politeness, patience and a caring attitude; and what's great is that they answer the phone early in the morning and super quickly, no need to wait. Highly recommend buying from McDonalds for reliability, professionalism, better, fairer prices and for peace of mind.

I’ve been in the plumbing & Heating industry for over 20 years and have been specifying and fitting McDonald cylinders for most of them. They always have a helpful and professional response to every enquiry. Their thermal stores have provided me and my customers with site specific bespoke arrangements required to give my customers the best possible hot water system for their needs. After sales support is also top quality. Thank you for years of providing a quality service.

Both great service and water storage cylinders. I've used McDonald Water Storage for 20-years in my Heating business and would highly recommend them.

Used them before and would use again. Tank arrived without the immersion. Phone call to office and it arrived a couple of days later. Job delayed but all good in the end

We are very grateful to David from McDonald Water Storage for his exceptional help, patience, and accommodation in completing our project to provide hot water to the sinks in our club toilet block at Cheshire Ghost Riders BMX Club. His communication was excellent throughout the ordering and delivery process, and the product is fantastic, providing the solution we needed.

Wonderful pleasant, competent staff, very quick responses, professional design work, great/perfect product for the job, compassionate in an emergency order, good delivery service. I couldn't be more pleased or impressed in this world where nothing seems to work right. First class service and kindness.
I just want to mention how wonderful Bradley was from beginning to end as well as Emily at reception and another receptionist, whose name I sadly cannot remember. I have nothing but gratitude for the company.

Ordering of parts and delivery couldn't have been better. Technical support helpful as always, and a free packet of haribo sweets in with parts packaging a welcome treat
