Hydraulic Accumulator Demo

Megaflo or Unvented hot water systems rely on the incoming water supply to deliver provide a superior level of performance. In the majority of cases where performance is an issue, this is down to insufficient pressure or flow supplying the cylinder. Every scenario is different! Simply installing a Megaflo system does not guarantee high performance showers, etc. It could be worse than an old vented system if incorrectly designed/installed! This demonstration video was prompted after a long conversation with the technical department of a major pump and expansion vessel manufacturer (Xylem/Lowara). Our call was to establish the maximum charge pressure of their potable expansion vessels. After very patiently trying to explain what we were trying to achieve, he insisted the flow rate CANNOT be improved without a pump. He finished the conversation as follows: Lowara: "I've been in this business a long time, and it can't be done". Me: "We've done it and it works". Lowara: Well good for you. Our products can't do that". Hangs up! We have run this exact demo with other brand expansion/pressure vessels and it works!
