Performance
Conditions:
- 200º boiler water supply
- 90º temperature rise
When the thermostat in
the inner tank calls for
heat, the boiler and circu-
lator start. Boiler water is
circulated around the
outer tank and heats the
domestic water in the
inner tank. After transfer-
ring its heat, boiler water is
returned to the boiler to be
re-heated. When the ther-
mostat in the inner tank
reaches its pre-set mark,
the boiler and circulator
shut off.
