    Unvented cylinder recommendations?

    Have 2m height and require a 500L unvented cylinder. Most will be just under this height so probably best if I go for a horizontal so it's not too tight. Question is, is there an unvented cylinder with solar (future proof if I install solar), indirect (heated by gas boiler), horizontal and 500L?
