Rated 5 out of 5 by from Great cylinder Good product with prompt next day delivery, Easy to fit with small adjustments to the pipe work. Too early to comment on reliability, but it has a 10 year warranty. Good value for money.

Rated 4 out of 5 by from Things to know I replaced my old copper tank with this unit and thought i would share my experiences. 1/Always wash out the tank as there WILL be bits of foam inside. Mine had lots and you don't want these in your pipes! 2/This tank has 2 side and 1 top hot water connections (total 3, plus the heater exchange coil connections) so if you might need a blanking connection. The description on here and the manufactures site doesn't show you this. 3/ You will need a Incoloy Immersion Heater. 4/ The connection positions WILL be in a different position to your old tank, so don't expect a quick swap out. The British Standards are meant to make easy but it wasn't and all pipes needed adjustment. Cant comment on reliability...yet. we will see in 10 years time :-) Hopefully that will help you!

I'd have thought this would be in the specifications, but it doesn't appear to be. Could you tell me the tank capacity, please?

compatibility of 71148 with existing 900 × 450 mm tank

Am confused - will the indirect SS replacement 71148 fit without alteration to present pipework?
Asked by: objectivus
Thank you for contacting us. The 815 x 450mm Stainless Steel cylinder has been designed to be as close to its copper counterparts as possible, however because so many designs of copper cylinders exist it is impossible to say that alteration wont be necessary, however in many cases alteration is kept to a minimum.
