Thermann Owner’s Manual
80L to 400L Electric Storage Water Heaters
Solar Upgrade
To find out more about upgrading to Solar, contact your local Reece branch.
Your Thermann 250L, 315L & 400L
tanks are solar upgradable.
Although the tank currently operates
as a standard electric storage water
heater, a solar upgrade kit can be
purchased to convert the water heater
to an electric boosted solar water
heater.
This will significantly reduce the
amount of electricity required to heat
the water.
Note: Due to the additional boosting
solar power source the standard
thermostat/ECO module must also
be replaced with a suitable type. ie.
ST1301133. This will be available as part
of the upgrade kit.
