no heat = no DHW

TimcoTimco Posts: 2,904Member
I have a service call tomorrow for a WM GV-4 that will not fire. It's a few towns north and I will be bringing a HSI. Question is, since these folks have an indirect, short of getting the boiler firing, is there no way to get them hot water? Has anyone seen a standard 40 gal WH on the DHW system as a back-up for hot water needs? I hate to see them without both...

    An electric

    HW tank could be plumbed easily, IF you have a 240V 30A circuit nearby.

    Or a long extension cord to a dryer outlet :)

    Indirect tanks with back up elements, like some solar tanks would sure be nice for back up in cases like this.

    I think we will be seeing more indirect tanks built with elements or provisions for.
