ABOUT YOUR WATER HEATER
WATER HEATER APPLICATION
This water heater is designed for use in a single family domestic dwelling for the purpose of heating potable
water. Its use in an application other than this may shorten its life.
MODEL TYPE
Your Solahart
®
Synergy
®
air sourced heat pump water heater is designed for outdoor installation only. The
310 HAV model heat pump water heater is recommended for connection to a minimum 16 hour per day
power supply.
A Solahart heat pump water heater consumes less energy than an electric water heater. The impact on an
electricity account will depend on the tariff arrangement of the water heater replaced and where you live.
Contact your energy provider for more information on tariff arrangements and cost comparisons.
The Solahart air sourced heat pump water heater has a vitreous enamel lined steel cylinder. The water
heater‟s evaporator absorbs heat from the surrounding air and transfers this heat into the water.
When hot water is drawn off and cold water enters the tank, the thermostat activates a fan, a compressor
and a circulator. The fan draws outside air in through the air inlet louvres at the top of the water heater and
the pump circulates water from the bottom of the storage tank through a heat exchanger. Heat is absorbed
from the air by an evaporator and transferred into the water through the heat exchanger. The resulting cold
air is then discharged through the air outlet louvres back to atmosphere and the heated water is circulated
back into the top of the storage tank. This process continues while ever heating is required until the water in
the storage tank reaches a temperature of 60°C.
Even on cloudy or cold days, heat is drawn from the surrounding air. The
heat pump will operate when the ambient air temperature is 5°C or higher.
The booster heating unit will operate when the ambient air temperature
falls below 5°C, if heating is required. The efficiency of the water heater
increases as the surrounding ambient air temperature increases.
Automatic safety controls are fitted to the water heater to provide safe and
efficient operation.
ELECTRIC BOOSTING
Ice may begin to form on the evaporator reducing the heat pump efficiency,
when the ambient air temperature falls below 7°C and the heat pump has
been operating for an extended period. At ambient air temperatures below
5°C, the water heater deactivates the heat pump operation and switches to
the booster heating unit. During this period the evaporator will defrost if
necessary.
The boost capacity in this mode is 220 litres. The water inside the tank will
be heated to a temperature of 60°C by the electric booster heating unit if
heating is required. The temperature setting of the sensor controlling the
booster heating unit is not adjustable and is set at 60°C.
MAINS PRESSURE
The water heater is designed to operate at mains pressure by connecting directly to the mains water supply.
If the mains supply pressure in your area exceeds that
shown on page
16, a pressure limiting valve must be
fitted. The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved.
A minimum water supply pressure of 200 kPa is required to enable the heat pump circulator and heat pump
system to operate effectively.
