Single Tankless Water Heater as a Solar Booster :

A tankless unit will be connected inline with the hot water output of a solar storage tank and the hot water

supply to the fixtures.

The supply to the tankless must be connected to a thermostatic mixing valve so

that the tankless does not receive water exceeding 140F

. The tankless unit(s) should be sized according to

the total demand of the application. When the water temperature drops below the T-stat setting on the

tankless and the flow is great enough, the tankless unit will engage.

Refer to the tankless Use and Care

manual for installation instructions and recommendations for the tankless water heater.
