BOSS™ Condensate Pump (Automatic) PS

The latest Grant Vortex Pro internal combination oil boiler features a 24 litre expansion vessel, neon diagnostic indicators and a factory-fitted condensate trap - all designed to make installation and servicing easier. With larger than normal plate heat exchangers, the hot water performance of this high-efficiency combi boiler is vastly increased. The two very accurate electronic temperature controls allow the boiler to operate in condensing mode on central heating and instant hot water production can be maintained. In addition, a low system pressure cut off switch protects the combi boiler in the event of system water loss.

The V4073A Valve has been designed to control the flow of water in domestic central heating systems, where both radiator and hot water cylinder circuits are pumped. It is typically suited for small to medium sized installations

Automatic Bypass Valve suitable for all heating systems up to 10 bar static pressure where a boiler bypass is required or radiator thermostats are fitted. It provides a simple method of ensuring adequate flow through boilers which require a bypass as well as reducing system noise. In systems fitted with radiator thermostats, the valve opens automatically as the TRVs or zone valves close down and the resistance of the system starts to exceed the preset pressure limit.

An electro-mechanical 24 hour timer offering a selection of constantly on, constantly off or timed operation, with switching possible at 15 minute intervals using tappets set around an analogue clock for simplicity.
