Would anyone know who manufactures a nice, inexpensive, standard, reliable,
indirect-fired water heater (ie a 60 gallon insulated tank with a some
copper tubing in the bottom, to put boiler water through to heat the tank) 
that also has some built-in 220V electric heaters for backup heating?

Thanks,

Nick
