Combination Water and Space Heating Applications – Commercial Use Water Heaters Only

Commercial use water heaters may be used for space heating or combination space heating/potable water heating applications, provided the following requirements and recommended piping diagrams are carefully followed.

WARNING

The following instructions must be carefully followed to assure safe and reliable operation of the water heater. All piping components connected to this water heater must be suitable for use with potable water. In Massachusetts, space heating piping length must not exceed 50 feet. Toxic chemicals, such as those used for boiler treatment, must not be introduced into potable water used for space heating. This water heater must not be connected to an existing heating system or component(s) previously used with a non-potable water heating appliance. When the system requires water for space heating at temperatures higher than required for other means, an ASSE approved mixing valve must be installed to temper the water for those uses in order to reduce the scald hazard potential.

1.Only commercial use water heaters may be used for combination water heating/space heating applications. Residential use water heaters will not be covered under warranty for water heating/space heating applications.

2.The temperature setting of the water heater thermostat must not exceed 160°F.

3.In combination space heating/potable water heating applications that require higher water temperatures than normally used for potable water uses, an ASSE approved thermostatic mixing valve must be installed to temper the water for those uses in order to reduce the scald hazard potential.

4.In order to assure adequate flow through the water heater, follow the recommended piping diagram and circulator specifications (see Figure 9).

5.An expansion tank will be required in all space heating applications.

6.A Y-type mesh strainer (#20 mesh screen) should be installed on the cold water inlet of the water heater to prevent clogging of the fine mesh screen on the water heater cold water inlet connection.

7.A water softener must be used if the water supply has a tested hardness level above 10 grains of hardness.

8.All piping must be ¾” copper or larger.

9.All components must be suitable for use with potable water.

10.The water heater should be located as close as practical to the space heating heat exchanger.

11.A check valve should be located after the circulator(s) to prevent backflow during potable water demands.

12.A heat exchanger may be required to separate the potable water from the space heating circuit in certain applications.
