Rated 5 out of 5 by from Well insulated Good cylinder, at a good price, comes in a box, so no damage to foam insulation, protective caps on trappings, works on both gravity, and fully pumped systems. Wouldn't, hesitate to purchase again.

Rated 5 out of 5 by from Plumber specified our plumber gave me the specifications of the new cylinder to replace a nearly 40 year old cylinder, and to try and remove the existing element might be fatal to the cylinder, it there fore made sense to replace the lot and have the comfort of knowing its all good. The cylinder comes ready lagged with a thick foam coating with easily accessible fitting points. Remember you are getting a lagged cylinder , other fittings such as an element and pipe fiitings will be needed consult a professional.

Rated 4 out of 5 by from Good cylinder, poor delivery A good quality cylinder, well packaged. Standard 1" tappings. Had a "Before 10am" delivery. Parcelforce rang my customer's door bell at 0730 and drove off before they could get to the door. Must have waited all of 10 seconds for them to answer. I spent half an hour phoning Plumbfix to get it sorted. Promised call backs never happened. It eventually reappeared after 11. Not impressed. Can't comment on reliability obviously.

What is the recovery time from 10 to 42 degC, and 10 to 60 degC with primary water at 75 degC flow and 65 degC return?

Asked by: toofondofpizza
To RM Cylinders. Thanks for your answer, however,it doesn't answer my question. I understand how to calculate the power required, but that doesn't tell me if the heat exchanger within the cylinder is capable of delivering heat at that rate. The heat recovery time to 42 degC would also be quicker than the recovery time to 60 degC, and I would like both numbers. Thank you in anticipation.

Whats the difference between a pumped cylinder and a gravity cylinder

I have a solid fuel trianco boiler, my hot water cylinder says for pumped systems only, not sure what this means.
Asked by: milldaw
All vented copper cylinders are manufactured for Pumped Systems only ie Boilers etc. If you have solid fuel which is normally a Gravity system, the cylinder ill not be suitable. Screwfix do not take cylinders for gravity, you would have to source via a proper plumbers merchant such as Plumb Centre/PTS/Graham's and quote you require a cylinder suitable for a gravity/solid fuel input.
