Hot Water
Generator Systems

Water to Water

Horizontal or Vertical
Jacketed & Insulated

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.

Availability

Hot Water Generator Systems are pre-engineered and
pre-assembled complete with all piping to meet your
specific application. And like every Lochinvar product, we
thoroughly test them to ensure proper performance from
the moment they’re installed.

Hot Water Generator Systems are available in horizontal or
vertical configurations in a wide array of gallon capacities.
Standard packages are available in tank sizes from 200­1000 gallons with single wall copper tube bundle heating
units. Custom configurations, smaller and larger tank

and tube bundles, and optional control packages are also
