Hyco Speedflow Pressure Reducing Valve And Expansion Vessel Kit

This kit provides the facility to apply outside air temperature control to the boiler water flow temperature which provides energy savings. The outside sensor provided measures outside air temperature and sends a signal to the boiler, which adjusts the maximum boiler flow temperature in response. If outside air temperature is greater than the system design temperature, the boiler flow temperature is reduced providing running cost savings. The boiler will operate in the condensing mode more frequently increasing savings. Once the sensor is fitted it is automatically detected. The sensor operation may be configured by adjustment of the boiler operating parameters, if necessary.

BOSS™ central heating expansion vessels are designed to absorb the increase in water volume in central heating systems during the heating cycle, protecting system components and pipe work, maintaining optimum system efficiency and reducing wear.

The BOSS™ sealed system kit contains all the components an installer would need to connect a BOSS™ central heating expansion vessel to the system. The kit includes a wall mounting bracket, filling loop, safety relief valve with gauge and a cross tee piece.

Mains pressure water heater which can serve a number of basins.
