Discuss Joule or Telford Vertical Unvented Indirect Cylinder in the Plumbing Forum area at

    Does any one know how reputable/reliable are Joule and Telford when it comes to their unvented vertical hot water cylinders?

    We require a 250l vertical cylinder for our basement and our plumber is used to installing Telford Tempest cylinders but read online that Joule may be a better alternative?

    I have 4 Telford tempest unvented cylinders to replace soon all leaking from inside the casing somewhere, just to let you know before you buy.

    25 year warranty on the Telford and I presume also on Joule??, so not going to cost you as long as you get them serviced once a year to keep warranty

    Joule would be my choice out of the two they do a floating baffel version now which looks impressive , Heatrae Sadias Mega flow patent has ran out so all the top manufacturers have their own versions now best of luck , kop

    How much do they go for, for a 250l and where can I purchase one from?
    Is Telford Tempest a really bad alternative to Joule?

    Install it proper and they will all do what there supposed to. Its not science. Not derogatory at all but these posts have caused disagreement previously
