1. One of the World's Most Efficient Ways to Heat Water

Congratulations on purchasing a SIDDONS Solarstream energy efficient Heat Pump Water

Heater, designed for Australian conditions to produce many years of low energy hot water.

This water heater typically uses up to 75% less energy than a conventional electric element

water heater by absorbing heat from the surrounding air of between -5 and 45 degrees C,

night and day. It works in hail, rain and shine and becomes more efficient as the air

temperature and humidity rise. You can expect around 20% greater efficiency per 10 degree

rise in the ambient air temperature.

SIDDONS, with its partners, designs and manufactures energy efficient Heat Pump Water

Heaters for global markets using the best quality components sourced from Australia,

Germany, Japan and China.

Heat Pump Water Heaters can be used for factories, schools, hotels, motels, restaurants,

hospitals, beauty salons, spas, laundries, etc.

1.2 Dynamic Cycle Flow Heating System

The Dynamic Cycle flow heating system is used to convert an average of 1 kW/h of input

electrical energy into 3.5 kW/h of heat energy, more or less, depending on ambient air

temperature and humidity. Cold water from the bottom of the storage tank is cycled through

the heat exchanger in the Heat Pump outdoor unit then back to the storage tank until all the

water is completely heated.

As the name implies, an air to water Heat Pump Water Heater is a machine that pumps or

transfers heat absorbed from the ambient air into the water. Even at - 5 deg C, there is

enough heat in the air to boil the liquid refrigerant into a gas. Once in the form of a gas, it

can be compressed to superheat up to 95 deg C; this heat is then pumped into the water

through a double layered, tube inside tube heat exchanger. One tube takes the hot

compressed gas whilst the other takes the cold water from the tank. The advantages of

this method are:

1.3 Reduce Greenhouse Emissions

With a SIDDONS Solarstream, you are greatly assisting the reduction of global greenhouse

gas emissions if you can replace bottled gas, wood fired or a conventional electric element

water heater, the latter typically consumes 1/4 to 1/3 of a household's power usage. If you want

your water heater to be completely carbon neutral, then also install a small electricity

generating system such as a Photo Voltaic solar panel or wind power.

· Excellent heating efficiency

· Stable hot water without over heating at the top or under heating at the bottom

· All of the tank water is heated
