Reviews
Indirect Hot Water Cylinder 900 x 450 120L is rated 3.7 out of 5 by 19.
Rated 5 out of 5 by from Seems a good tank. Came well packaged although the box wasn’t big enough to cover the height of the tank. Connection locations were not quite the same as the old ,whereas other tanks I’ve fitted have been the same. So some annoying extra plumbing in was needed.

Rated 4 out of 5 by from Excellent Customer Service from RM Cylinders I bought this tank almost two years ago. It recently developed a small leak from below the element flange. As Tool station warrantee only one year I gave the manufacturers a ring and within four days a chap was dispatched to my address who replaced the tank for me free of charge with no fuss what so ever. Very impressed and grateful to Eddie and his team at RM cylinders for their prompt action and excellent customer service. Simply brilliant thanks.

Rated 4 out of 5 by from Better than the reviews suggest? Purchased in a hurry as existing cylinder started to leak. A few quid cheaper than rival, but the reviews weren't altogether glowing. The threads were a bit coarse and reviews suggest PTFE Tape wasn't good enough, so purchased a tube of Fernox L-SX and barely had a leak on any joint. Very satisfied.

Rated 1 out of 5 by from Avoid at all cost Needed new cylinder in a hurry and paid extra for next day am delivery- arrived by 11am next morning. Fitted with few issues, other comments re excess foam true but not a problem. Minor changes to pipework require but had hot water and heating by tea time. Two days later woke to the sound of running water and found the kitchen ceiling sagging alarmingly with water dripping through it. All joints were still sound but there was a large pool of water behind the cylinder running through the floor around the emerging pipes. Stripped cylinder out and refilled outside. Water dripping through foam and when I cut this away found the soldered seam between bottom and sides had failed.

Rated 1 out of 5 by from Poor quality Lasted only 14 months before developing a leak. Manufacturer's warranty is 24 months but because it was over 12 months there was no assistance or cooperation from Toolstation. Still trying to get RM Cylinders to collect faulty cylinder and refund me.

Rated 4 out of 5 by from Needed a lot of foam trimming The cylinder is good and the foam thick and quite tough. The problem is the relief around the 5 ports was poor. Only the hot outlet was OK. Worst was the immersion heater port that was off centre and needed about 20mm cut away one side just to get a box spanner in. You need a box spanner for this cylinder. An offset spanner will not work. I must have spent a hour cutting foam back which I should not have to.

Rated 4 out of 5 by from looks presentable In the process of fitting at the moment, tell you what its like when running. The test will be after a few years though

Rated 5 out of 5 by from Easy replacement Wanted a quick replacement for a tank with a weeping leak. Guess what, your favourite diy suppliers don't stock these anymore. Toolstation provided one next day from an on line order, delivered to my home, before middayin my case, at a competitive price. Terminal connections were compatible with the original fittings so no running out for new bits. Terrific service, absolute lifesaver!
