Domestic Water Mixing

Use when water temperature produced by heater is hotter
than desired at point of use. Many codes require that water
supplied to the system be limited to 120° F (49° C) max.

Fig. 5. Water heater is used for domestic water and space
heating. Dimensions shown in in. (mm).
1.= Check Valve.
2. = Alternate Pump Location.
V.= Any device which turns the domestic water system into
a closed system, such as backflow preventers, check valves
or pressure reducing valves.
NOTE: "V" is optional depending on local codes. If a "V"
type valve is used, it is mandatory that a thermal
expansion tank be installed as shown. Otherwise
dangerously high pressures could result or water
heater safety relief valve will frequently expel
water. If a "V" device is not used, a thermal expan-
sion tank is not required.

Space Heating

Boiler must operate at a water temperature higher than
desired temperature in the heating system in order to
perform at maximum efficiency. Example: Radiant floor
heating.
