or heating so no harm
still need pump overrun on hot water so whenever boiler fires still needed depending on manufactures instructions
only with combis this is a heat only but then you wouldnt need the rf solution as its inside the boiler
heat only are the most prone to this issue depending on boiler siting and pipework after boiler.
still doesnt answer your question why would a heat only need the pump overrun on hot water (when the hot water is used)
so whats the issue when the boiler doesnt have its overrun (safety wise)
its not a safety issue boilers will lock out on overheat if heat not being dissapated after stat shuts them down. its the long term damage being done to the heat exchangers that is the problem
would be best but not mandatory on ss hexs as they can take the heat
All the cables between the boiler and the immersion cupboard are all used the engineer tells me. I either place a new cable under the floor back to the boiler just for over run or I use the RF kit i'm told.
ok shaun could have had a debate
Agreed. But if it has been done properly it will.
