4.6 Water connections – solar storage hot outlet
Hot water outlet of solar storage tank is to be connected to existing water heater cold inlet
(through third ball valve and into tee below initial ball valve). Using dealer-supplied materials
(copper pipe and sweat fittings), fit hot water outlet of solar storage tank (open port of
thermometer assembly tee at top of tank) to “cold” inlet of existing water heater (
Fig.4.4.1
).
Do
not use PEX as solar water heating appliance can produce very hot water that exceeds
PEX temperature ratings
.
4.7 Water connection to hot water distribution network
1. Ensure hot water outlet of pre-existing (now back-up) water heater is connected to home hot
water distribution network.
2. Hot water outlet to home may require anti-scald valve. EnerWorks highly recommends anti-
scald valve (such as
Honeywell AMX Series Thermostatic Mixing Valve AMX101-US-1
) to be
installed on all new and retro fit installations. Check local codes and regulations regarding
installation of anti-scald valves and set point requirements.
This installation may have to undergo inspection – check local codes and
regulations.
