I have a megaflow system with Valliant boiler.
The boiler is working.
The hot water flow pipe from the boiler goes to a "T" junction.
Either side of the "T" junction is a zone valve.
The CH zone valve seems to operate & hence my radiators warm up.
The zone vavle to the tank? not sure, it's a Honeywell so can manually switch and hot water flows to the tank, I think?
Has the zone valve gone wonky? is this why I dont get hot water automatically?
