Unvented Hot Water Cylinders by TREPP & CO

TREPP & CO services

Unvented Hot Water Cylinders

Installation, servicing and repair of unvented cylinders, including expansion vessels and safety discharge.

Unvented cylinders give mains-pressure hot water to several outlets at once, which is why they suit larger homes and properties with more than one bathroom. They are also a controlled system that has to be installed and serviced by a qualified engineer.

We install, service and repair unvented systems, including the expansion vessel, temperature and pressure relief valves and the discharge arrangement.
