Indirect Hot Water Cylinder 900 x 450 120L is rated

Hooray, hot water again!
Cylinder now installed and working well. This was a like for like replacement and only required a small realignment to one pipe feed. Spent some time trimming away the foam around each connection but over all, very pleased. Got me out of a tight corner in lockdown!

Bought this to replace a clients HWC which was leaking near the hot water outlet. The pipe connections on the side were approx 20mm higher on this cylinder so had to adjust length of pipes on boiler connections. Unfortunately the cylinder started to leak somewhere around the joint between base and side so had to replace after 9 days. I am awaiting compensation from manufacturers via Toolstation. As this has ocured during the covid pandemic things may be protracted. Will post how things progressed when I revue the replacement!

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.

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.

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.

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.

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.
