Lochinvar’s Hot Water Generator Systems are ideal when
boiler capacity is sufficiently sized to cover potable hot
water demand and provide source water for hydronic
heating systems. Hot Water Generator Systems use steam
or boiler water as an energy source and can provide high
recovery rates, making them an economical water heating
system.
