Multiple Tankless Heaters - If two tankless heaters are installed in the boiler, it is recommended that each heater be
installed in parallel with its own mixing valve, relief valve, flow restrictor, etc.. This will permit either heater to be
removed from service for maintenance while still providing some domestic water to the building.
