Unvented Cylinders

Unvented water heating is the fastest growing sector of the UK market, led by Heatrae Sadia's MEGAFLO Eco.  Unvented systems are fed directly from the cold water mains supply and offer a number of benefits compared to conventional systems.  Higher pressure and flow rates at all hot taps, balanced hot and cold water supplies, no special taps required.  Manufactured from the highest quality materials they offer unrivalled peace of mind backed by an impressive range of extended on-site sevice support guarantees.
