WRAS Approval Number: #250702708

Range of heat interface units providing heating and instantaneous hot water. The central heating and hot water are generated via plate heat exchangers. The central heating circuit contains a pressure relief valve (3.0 bar) and an expansion vessel. The cold inlet supply to the plate heat exchanger incorporates an in line single check valve assembly, (suitable for backflow protection against Fluid Category 2). Max Temperature & Pressure for models A/7892284 & B/7892283: Primary Circuit: 6.0 bar at 90°C DHW Circuit: 10.0 bar at 55°C Secondary Circuit 6.0 bar at 90°C Max Temperature & Pressure for all other models: Primary Circuit: 16.0 bar at 90*C, DHW Circuit: 10.0 bar at 65*C, Secondary Circuit 3 bar at 85*C.
