ABOUT YOUR WATER HEATER
8
DOES THE WATER QUALITY AFFECT THE WATER HEATER?
The water heater is suitable for most public water supplies, however some water qualities may have
detrimental effects on the cylinder, gas booster heat exchanger and fittings. If you are in a known
harsh water area
you must read page 52. If you are not sure, have your water quality checked
against the conditions described on page 52.
HOW LONG WILL THE WATER HEATER LAST?
There are a number of factors that will affect the length of service the water heater will provide. These
include the water quality, the water pressure, temperature (inlet and outlet) and the water usage
pattern. However, your Solahart water heater is supported by a comprehensive warranty
(refer to
page 54 ) .
ANODE PROTECTION
The anode(s) installed in your water heater will slowly dissipate whilst protecting the cylinder. The life of
the water heater cylinder may be extended by arranging for an authorised person to inspect the
anode(s) and replace if required.
The suggested time after installation when the anode(s) should be inspected is 8 years.
For softened water supplies or in areas of poor water quality, it is recommended the anode(s) be
inspected 3 years earlier than shown (refer to
“Water Supplies” on page 52).
FREEZE PROTECTION
Solar Circuit
The solar circuit must be installed with a continuous fall in the pipe work from the solar collectors to the
solar storage tank, the solar hot and solar cold pipes must be fully insulated with closed cell polymer
insulation (minimum thickness 13 mm) and the system charged with correctly mixed closed circuit fluid
to offer protection against freeze damage. The system has NO WARRANTY for freeze damage if there
is not a continuous fall in the solar hot and solar cold pipes, or they are uninsulated, or the closed circuit
fluid has been incorrectly mixed (refer to
“Warranty Exclusions” on page 53).
The anti freeze control of the solar circuit is designed so there is no closed circuit fluid in the solar
collectors or solar cold and solar hot pipes when the pump is off.
Gas Booster Water Heater
The gas booster has a frost protection system. The frost protection system will protect the gas booster
from damage, by preventing ice forming in the waterways of the gas booster, in the event of freezing
conditions occurring.
Notes:
• The gas booster frost protection system will be rendered inoperable if electrical power is not
available at the water heater. Damage caused by freezing due to the unavailability of power at the
water heater is not covered by warranty (refer to “Warranty Exclusions” on page 53).
• If it is necessary to switch the power off to the water heater and there is a risk of freezing, then it is
necessary to drain the gas booster (refer to “Draining the Gas Booster Water Heater” on page 9).
• Pipe work to and from the water heater must be adequately insulated to prevent freezing.
• The water heater is not suitable for installation in areas where the ambient temperature falls below -
20ºC (including wind chill factor).
• Refer to “Warranty Exclusions” on page 53.
