ESH Ecosmart Heater
The Ecosmart Heater should only be used as a
supplementry heater in conjunction with a
Ecosmart supply fan with integral electric heater.
It must not be used with any other fans.
The heater is a 3kW single phase unit that requires an
independent 230V mains supply to the top mounted
terminal box and is supplied with a pre-plugged 10m length
of communications cable.
This heater will provide additional heat where the desired
temperature cannot be achieved by the supply fan’s integral
heater alone.
Note: the air velocity through the heater section must be
1.5m/s or greater.
Installing the Heater
The Heater must be fitted indoors, away from any water
spray or source of steam.
The heater is installed into the ductwork (by others) using
the fast clamps at the downstream side of the supply fan.
Larger, heavier units should be adequately supported.
