VI) COMBO HEATING

WARNING:

Keep the area around the heater clear and unobstructed.

This section serves as a guide for the installation and use of “Combo” heating systems utilizing a domestic water heater that has been specifically approved for such use. It is writ- ten for those knowledgeable in the required trades and pro- fessionals involved in the design and installation of Combo Heating Systems.

It is the responsibility of the installer/designer to follow all applicable codes to ensure the effectiveness and safety of the installation.

Read Before Proceeding

CAUTION:

Keep safety your first priority. Take all pre- cautions to avoid creating a fire, health or safety hazard.

The following requirements must be met for the installation of Combo Heating Systems:

1.All components used for the distribution of water in the heating loop must be suitable for potable water. These include all piping, fittings, solder and fluxes, pumps for circulation of water, valves, etc.

2.The water heater must not be connected to a hydronic heating system that has been used previously.

3.No boiler treatment chemicals of any kind shall be intro- duced into the system.

4.The Combo System components must be selected and sized to meet and maintain the total calculated demands for both domestic service hot water and space heating requirement. The sizing and installation must be per- formed in accordance with good engineering practice such as “ASHRAE Handbooks”, HRAI, “Hydronics Institute Manuals”, CSA B139-04, NFPA 31, ANSI Z223.1, CSA F280, National/Provincial Building Codes, CSA C22.1, ANSI/NFPA 70, CSA B51 and/or codes having jurisdiction.

5.The air handler (fan coil) and/or the circulating pump in a baseboard hydronic loop will require a dedicated 120V circuit. This must be provided and identified for this pur- pose.

6.All piping between the water heater and the air handler or hydronic baseboard loop must be adequately insulat- ed to reduce heat loss.

7.If the local jurisdiction requires a back-flow preventer in the cold water line, an expansion tank of adequate size must be installed.

8.“Combo” Heating Systems require higher water temper- atures than other applications. When the system is used to supply water for Combo Heating applications, a means, such as mixing valve, must be installed to tem- per the water in order to reduce scald hazard potential (see Figures 14, 15 & 16).
