UNVENTED CYLINDER CONTROLS

Inlet Control Group

An Inlet Control Group consists of a Pressure Reducing Valve, Check valve and Expansion relief valve, provided as one assembly.

The Inlet Control Group is fitted on the mains cold water supply to an unvented cylinder to control pressure, protect against backflow conditions and permit excess pressure and temperature to be relieved. Honeywell can provide alternate solutions in 22mm and 28mm sizes, to meet various market requirements.

Temperature and Pressure Relief Valves

Available with either 1/2", 15mm or 3/4" connections, the temperature and pressure relief valve is fitted to the hot water cylinder so as the temperature probe is submersed in the water at the hottest point. The Temperature and Pressure relief valve should be factory fitted by the manufacturer of the unvented cylinder and is a requirement of the Building Regulations G3.

MODUS

Honeywell is a member of MODUS, manufacturers of Domestic Unvented Systems and in common with all Modus members will provide advice on all matters relating to the installation of Unvented hot water cylinders.
