Heatrae Sadia Amptec RL2 Relay

The RL2 relay is required for when two Amptec boilers of high kW are in use on the same circuit or in the same dwelling. The RL2 prevents both boilers from operating at the same time, as this could overload the overall power capacity, but temperatures would still be effectively maintained because both boilers alternate to keep water in the pipe and heating circuits hot

Amptec Electric Boiler

Compact and unobtrusive, Amptec works with standard radiators, programmers, circulating pumps, room thermostats and thermostatic radiator valves, to heat water for radiator or underfloor heating systems. Amptec is available in a range of kW sizes and is ideal for extensions, loft conversions, conservatories and garages where space is at a premium
