Rated 2 out of 5 by from Problematic Bought this cylinder to upgrade for a customer who wanted more stored water . Was disappointed that I had to buy 1’’ connectors but that wasn’t too big a deal . I was more annoyed that after fitting it , I found that the coil was leaking from where it hadn’t been tightened up properly from the backing nuts holding it in place . I had to cut out a rather large section of the lagging away so I could sort the problem and tighten the backing nuts myself ! Shouldn’t happen. First time in 40 years I have had this , wont use RM cylinders again and no doubt there warranty wouldn’t account for much either as they would just blame the fitting

Rated 5 out of 5 by from RM Cylinder I bought this cylinder as a replacement for my 20 year old Telford due to it leaking from one of the welds. I ordered the cylinder on Sunday morning and it came into my local branch on the following Tuesday. A Good quality cylinder and seemed to be of an average value, I like the fact that the cylinder has its own shower feed to save you having to use a Surrey flange when fitting a pump. Fitted the cylinder that evening and only had to alter a couple of the feeds. So far so good so would recommend this cylinder. You will want 3 inch male irons and 2 inch female irons to go with the cylinder.

Website Q&A info 2017, is this still current?

What size immersion does this tank take?

Asked by: Steady18

is this cylinder gravity fed to the coil

Asked by: rod8
Hello rod8, All cylinders are standard for Pumped systems only. If a cylinder is required to work on a heat source such as solid fuel/gravity a special cylinder with gravity coil is required. This type of cylinder would not be available from Screwfix and would need to be ordered from a plumbers merchant. Thank you for using Q&A SW

What is the Secondary Return for?

Asked by: Stv1der
Some people have implied that this can be connected to a shower pump but this may not be correct. Apparently you can have a constantly circulating hot water circuit to distant taps or showers, that bypasses the taps when the tap is not in use and returns to the cylinder via the secondary return. See youtube: SECONDARY RETURN HOT WATER SYSTEMS
