Solar Hot Water Systems

A solar hot water heater can be a great investment if you’re looking to replace an old, inefficient hot water heater, and particularly if you’re trying to work out what kind of system to install in a new home. A solar hot water system gets most of its energy from the sun, so it cuts down on your energy bill and also produces a lot less greenhouse gas emissions. 

Australian Hot Water can take care of your solar hot water needs, serving you from locations throughout Sydney, Canberra and Newcastle.

What is a Solar Hot Water Heater?

A solar hot water heater uses solar panels or collectors to absorb the thermal heat from the sun, that then heats water in a storage tank. Solar panels or collectors need to be exposed to direct sunlight, so they ideally need to be installed on a roof. Sometimes the tank is stored on the roof, or otherwise on the ground inside or outside the home. Roof mounted highline solar water heaters are close couple style that have the solar collector or panel directly connect to the storage tank. The heated water from the collector or panel will rise into the storage tank naturally by thermal syphon due to the angle and pitch of the roof. Flat roof houses will require a pitched angle frame to mount the solar product on to gain the best thermal sunlight. The other style of solar water heating is the split lowline with the storage tank located on the ground level, and only the solar collectors or panels located on the roof. This type of product requires a circulating pump to transfer the heated water from the solar collector back down to the storage tank. The circulated water will be controlled by a differential electronic controller and sensor wires to ensure only hot water will travel back to the storage tank, and shut down the circulating pump when there is no sunlight or the storage tank is full of hot water, to save energy.

A solar hot water heater can usually provide between 50 and 90 percent of the free energy you need to heat a storage tank - some days it will supply more free energy than others, depending on the weather. So a solar system always comes with either a gas or an electric booster to provide the rest of the energy needed to heat the water tank -  required for overcast or rainy days or high hot water usage periods.

How Do Solar Water Heaters Work

Most solar hot water systems use solar collectors or panels to absorb energy from the sun. Water is heated by the sun as it passes through the collectors, and then flows into an insulated storage tank for later use. In passive systems, water flows unassisted between the collectors and the tank. In active systems, water is pumped between the collectors and the tank.

As solar hot water is rarely completely adequate for a household’s hot water needs, the storage tank is usually fitted with a booster. This may be powered by electricity, gas or solid fuel, and heats the water when sunlight is insufficient, such as on cloudy or wet days, or during winter when there are fewer daylight hours. Some solar water heaters also have frost protection to prevent damage in frost prone areas.

Benefits of A Solar Hot Water Heater

For a typical household, water heating accounts for about 30 percent of total greenhouse gas emissions and household energy use. Depending on the climate and the model of heater, a solar water heater can provide between 50 to 90 percent of your total hot water requirements.

Choosing the Right Solar Hot Water System

Australian Hot Water supplies and installs a wide range of solar water heaters from all the leading manufacturers. As the average household uses its water heater many times a day, it is important to choose the right system. We can help you to select the most effective and energy efficient water heater for your property and lifestyle. To have a discussion about which solar hot water system would suit your property, call us for expert advice.

It is important to note that the upfront cost of a solar hot water system, including installation, is higher than electric or gas water heaters. For most households, energy bill savings will compensate for this initial cost difference over time.

Solar Hot Water System Rebates

In addition, your household may be eligible for government rebates and incentives to offset the cost of a solar hot water system.
