ELEMENT:
Solarhart 'Black Chrome II' solar hot water system with a gas boost
AIM:
An average of 40% of the total energy used by a household is used in
the heating of hot water. Using a passive source to provide this household
necessity cuts down the total energy demands of the house.
A solar hot water system can reduce the energy consumption of a house
by around 30% and reduce water heating bills by up to 80%.
STRATEGY:
Minimise The Use of New Resources
A solar hot water system uses solar energy rather than electricity or
gas to heat the water. This reduces greenhouse gas emissions. In Australia,
it has been shown that if all the users of electric water heater were
to convert to solar, a 20% reduction of greenhouse gas emissions would
result. Each solar hot water system can prevent up to 4.5 tonnes of CO2 from entering the atmosphere each year.
Low flow shower roses, water efficient appliances and insulating hot
water pipes can make substantial reductions in water and energy use.
The special features of this hot water system include:
- Polycarbonate tray insert between the jacket of the storage cylinder
and the CFC free polyurethane foam to prevent the ingress of moisture
and water.
- Large 33mm magnesium anode to handle various qualities of water through
out the life of the system. No replacement is necessary for twelve years.
- Full mains pressure operation. The storage cylinder is designed to
operate under mains pressure.
- A 1 000 kPa pressure and 99 deg C temperature relief valve is supplied
with the system to ensure that the hot water in the storage cylinder
is maintained within the pressure and temperature limits.
- Heat dissipation systems.
- Fluid Level monitoring systems.
