Discuss Secondary return hot water in the USA area at PlumbersForums.net
Scheduled is ok. On horizontal unvented cylinders, even without a hot return, a pump is stipulated to circulate the tank and prevent stratification. It’s recommended to run the pump for an hour a day.(Disclaimer: From over a decade old memory)
55 will do and lagging is usually required, I don't think it has to be continuous either and so can be scheduled.
Well if it's circulating at 55°C for an hour, that is enough to kill all the legionella. Probably if the cylinder is held at 60°C, then 55° is to allow for potential heat losses over the length of the pipe.Wouldnt it have to be the same time as the boiler is heating the cylinder?
othetwise you are just shifting water around and not heating it all up to 60
