HOW YOUR WATER HEATER WORKS
SOLAR OPERATION
The Solahart Streamline closed circuit solar water heater has its vitreous enamel lined solar storage
tank installed at ground or floor level, remotely from the solar collectors. This water heater is an indirect
solar hot water system with a heat exchanger in the solar storage tank. The heat exchanger is filled with
closed circuit fluid and is connected to the solar collectors forming a closed circuit.
As the sun heats the solar collectors, the increase in temperature activates the pump. The pump
switches on whenever the solar collectors are hotter than the water in the tank. The pump moves the
closed circuit fluid from the solar storage tank heat exchanger through an insulated copper pipe to the
solar collectors to be heated by the sun’s energy and then back to the heat exchanger. Heat transfers
from the closed circuit fluid in the heat exchanger to the water stored in the solar storage tank.
This process continues while solar energy is available and until the water in the solar storage tank
reaches a temperature of approximately 75

reaches a temperature of approximately 75
°C. The pump is then deactivated and the closed circuit fluid
in the solar collectors and solar pipe work drains back into the heat exchanger in the solar storage tank.
The closed circuit provides protection to the solar collectors and solar circuit in harsh water areas. The
drain back principle provides protection to the system in freezing conditions.
Automatic safety controls are fitted to the water heater to provide safe and efficient operation.

GAS BOOSTING OPERATION
Water stored in the solar storage tank passes through the gas
booster when a hot tap is opened. The gas booster is for heating
the water at times of low solar energy gain, such as during cloudy
or rainy weather, or during winter months.
Solar heated water can reach temperatures up to 75

Solar heated water can reach temperatures up to 75
°C in the solar
storage tank. When the solar heated water temperature is above
58
58
°C, the gas booster will not boost the water temperature.
The gas booster operates automatically if heating of the water is
required. When the solar heated water temperature is below 58
°C,
the gas burners ignite to provide immediate heating of the water to
a minimum temperature of 60
a minimum temperature of 60
°C. The heat produced by the burner
is transferred to the water through the heat exchanger. The water is
heated to a constant temperature by the automatic adjustment of
the gas supply to the burner to suit the water flow rate. The gas
burners extinguish when the hot tap is closed.
Automatic safety controls are fitted to the water heater to provide safe and efficient operation.

WATER OUTLET TEMPERATURE
This water heater has two outlets. One is a hot water outlet and the other is a tempered water outlet.
The purpose of the hot water outlet is to deliver hot water at between 60°C and 75°C, usually for
kitchen and laundry use. The purpose of the tempered water outlet is to deliver water up to 50°C,
usually for bathroom or ensuite use.
The tempered water outlet is from the tempering valve, located under the pipe cover at the front of the
water heater immediately below the gas booster. The tempering valve is the brass valve with a green
plastic cap. The tempering valve mixes hot water from the solar storage tank and gas booster with cold
water from the mains supply and delivers tempered water from its outlet.
The hot water outlet is located above the tempering valve. Depending upon how the water heater was
installed, either both or only one of these outlets may have been plumbed to the hot water pipe work in
the premises.
