Owner’s Manual – Solar Water Heaters

H3165 029664 Rev. B
Introduction
General:
This Owner’s Manual applies to the Dux
Ecosmart range of Electric and Gas Boosted
Solar Water Heaters.
Electric Boosted Solar Water Heaters:
Solar water heaters heat water by pumping it
through the solar collectors when conditions
are suitable.
During the winter months or when it is
cloudy, there may not be enough solar
energy gain available to heat the required
quantity of water. An electric element is
installed in the storage tank of the water
heater to boost the water temperature as
required. The electric element is controlled by
a separate thermostat.
The plumbing and electrical connections to
the solar collectors are the same for both
electric and gas boosted models. The hot
water plumbing connection and the electrical
connection to the boost element are specific
to the electric boosted models.
Throughout this manual, most pages are
common to both electric and gas boosted
models while some pages are specific to
electric boosted models. Those pages that
are specific to electric boosted models are
clearly identified.
Electric Boosted Solar Water Heater Models
are:
• 250DPM36
• 315DPM36
• 400DPM36
Gas Boosted Solar Water Heaters:
Solar water heaters heat water by pumping it
through the solar collectors when conditions
are suitable.
During the winter months or when it is
cloudy, there may not be enough solar
energy gain available to heat the required
quantity of water. An instantaneous gas
water heater is installed between the storage
tank of the water heater and the hot water
outlets to boost the water temperature as
required. The instantaneous gas water heater
is controlled separately.
The plumbing and electrical connections to
the solar collectors are the same for both gas
and electric boosted models. The hot water
plumbing connection and the gas connection
to the instantaneous water heater are specific
to the gas boosted models.
Throughout this manual, most pages are
common to both gas and electric boosted
models while some pages are specific to
gas boosted models. Those pages that are
specific to gas boosted models are clearly
identified.
Gas Boosted Solar Water Heater Models are:
• 250DP0
• 315DP0
• 400DP0
