By Ralf — Gas Safe Registered Engineer | 14 January 2026 | Plumbing
Delivering high-performance hot water in Borehamwood, WD6 this week — Ralf installed a premium Ultraflow unvented cylinder, designed to provide powerful, consistent water pressure throughout a larger home with higher hot water demand.
Built for demand, not just capacity
Our engineers specialise in these complex pressurised systems, ensuring every connection is safety-compliant and optimised for energy savings. A larger home with several bathrooms running simultaneously needs more than just a bigger tank — it needs a system engineered to hold pressure under real, simultaneous demand, which is exactly what a premium unvented cylinder like the Ultraflow is built for.

Common Questions
Premium unvented cylinders are built to deliver powerful, consistent water pressure throughout larger homes with higher simultaneous hot water demand — multiple bathrooms running at once, for example — while remaining fully safety-compliant.
Yes, it's often the better option for exactly that situation. Unvented systems deliver mains pressure to every outlet simultaneously, avoiding the pressure drops that gravity-fed vented systems can suffer when multiple taps or showers run at once.
