we have a sealed pressurised system with two motorised valves and using a megaflow for hotwater. when the system is on hot water only, our two towel warmers get hot, i assume as well as for convenience they provide a boiler bye pass circuit.
however when the system is on central heating only the same towel rails also get warm.
can someone explain how the towel rails can act so independently
