— About This Service
Blueflow supply and install unvented hot water cylinders for homes and commercial properties across Essex, with full commissioning and safety checks included. We fit direct and indirect cylinders, connect to boilers or heat pumps, and carry out TMV and PRV setup to ensure safe, high‑pressure hot water. All work is Gas Safe Registered and F‑Gas qualified where required, with 15 years’ trade experience and comprehensive certification.
— Our Process
A qualified engineer visits to assess mains pressure, hot water demand, cylinder location and compatibility with boilers or heat pumps, then proposes a system and layout.
We supply the right unvented cylinder and ancillaries (expansion vessel, PRV, TMV, AAV) and install to manufacturers’ instructions and industry regulations.
Full commissioning, safety checks and paperwork on completion — thermostat calibration, PRV testing, pressure checks and user handover with compliance certificate.

— FAQ
If your property has reliable mains water pressure and you need high‑pressure hot water to multiple bathrooms or appliances, an unvented cylinder is often the best solution. We carry out a pressure and supply assessment during a site survey and advise if modifications to the incoming mains or additional controls are needed.
