Hello all, I would ideally like to link my existing Refleks diesel stove system that heats one radiator to my Webasto Thermotop E system that heats the calorifier and one bathroom radiator. I don't want to use the Refleks and Webasto at the same time, but in the winter, even when running the Refleks 24/7, I have to use the Webasto to heat hot water (I don't want to run engine just for HW). The Refleks has a pump in the circuit. Has anyone linked a Refleks type stove with a Webasto type heater ? My thoughts were to install full-bore gate valves between the two systems so they could be run completely independently if required (i.e. as they are now), but when valves are open all radiators and the calorifier would be heated by whichever heat source was running. Both systems have their own open header tanks. My only real concern is if running the pump in the Refleks circuit could damage the internal pump in the Webasto when the circuits are joined. Any advice appreciated! Thanks
