The Delta Performance Combination Heater delivers heat and hot water in a single, compact foot print.

Unlike other water heaters that try to perform the function of space heating with domestic hot water, the Performance utilizes two separate water circuits, one dedicated to space heating (outer steel tank) and the other dedicated to the production of domestic hot water (inner stainless steel tank).

The unique closed heating loop "water barrier" eliminates direct contact between the source of heat and the stored domestic hot water, increasing the life expectancy of the product. At the same time tempered 120 deg. F domestic water is distributed in the house, 180 deg. F water in the outer tank is circulated through the heating loop, providing comfortable, efficient space heating at the desired temperature.

Features zero clearance to combustables and 85%+ combustion efficiency.
