Hi,
I have a Vaillant ecoTEC plus 937 boiler, which has a shift load storage tank to provide immediate hot water before the combi kicks in. The boiler has developed a leak, which appears to be coming from the area of the shift load storage tank area.
My question is, is there a means to isolate the shift load storage tank, so that I could drain it, but then also use the boiler as a pure combi boiler for hot water until I can get the leak fixed.
Thanks in advance,
Mark
