Solar Hot Water

Installing a solar hot water heater can reduce your water heating costs by up to 80%.

Using solar to heat water does not produce any harmful greenhouse gas emissions & conventional hot water heating systems account for around 20% of a household’s greenhouse gas emmissions.

Coldflow Heating & Cooling have partnered with Apricus Australia, Australia’s leading evacuated tube solar hot water supplier. Together we aim to supply solar hot water systems that are of the highest quality, competitively priced, and all backed by superior after sales service & warranties.

How the system works

Gas systems

In areas where natural gas or LPG bottle gas is available the Apricus gas boosted solar hot water system is an extremely efficient choice.

The solar collector heats the water in the tank. If the water requires some additional heating the booster heats the water to the required temperature. The gas booster only heats water when required, therefore saving you money through reduced gas consumption.

The complete system includes:

  • Manifold, Evacuated Tubes and Heat Pipes
  • Standard pitch frame. (Optional frames are available for a flat or low-pitched roof.)
  • Circulating Pump
  • Solar Controller
  • Steel or Vitreous Enamel water storage tank.
  • Gas Booster
  • Tempering Valve

Electric systems

If no gas supply is available, an Apricus electric boosted solar hot water system is the ideal choice.

Water in the storage tank is heated by the Apricus solar collector with backup boosting as required by an off-peak element in the bottom of the tank.

The complete system includes:

  • Manifold, Evacuated Tubes and Heat Pipes
  • Standard pitch frame. (Optional frames are available for a flat or low-pitched roof.)
  • Circulating Pump
  • Solar Controller
  • Stainless Steel or Vitreous Enamel water storage tank.
  • Tempering Valve

System Sizing

Solar collectors are a supplemental energy source. Solar thermal cannot totally replace traditional energy sources (gas or electricity) as it is not always sunny! A solar thermal system will therefore have a backup boost from electricity or gas to ensure you always have hot water.

A correctly sized solar system can save between 50% and 80% off your annual hot water energy bills, depending on your location and water usage patterns.

By reducing the amount of gas or electricity (or other fossil fuel source) that is used, you are also directly reducing CO2 emissions, which is a major factor in helping to combat global warming.

Save Money

With the rising prices of electricity, gas and fuel for your car, saving energy has become a real concern for everybody. There are many ways to reduce your energy bills without compromising your lifestyle. Hot water is something we just can’t do without, as there is nothing like a good, hot shower. Hot water, however, requires lots of energy, as much as 15kWh for an average family of four. That can equate to more than half of your household’s energy consumption and, therefore, your energy bill. Space heating is also another luxury that uses enormous amounts of energy.

Fortunately thermal solar collectors can greatly contribute to the energy required for hot water and heating, cutting usage of traditional energy sources. This means a reduction in an average household’s hot water bills from 60% to 80%, a saving of around $300 to $500 each year. Furthermore, the money spent on your solar collector is actually an investment that will provide long-term returns.

In addition the generous rebates that are available provide further savings on the overall cost of a solar hot water system.

RECs & Rebates

Water heating via a standard electric hot water system, is the largest single source of greenhouse gas emissions from the average Australian home. In an effort to reduce Australian greenhouse gas emissions the Australian Federal & Victoria’s State government have introduced a number of generous rebates for consumers. These rebates provide significant financial incentives for purchasing sustainable hot water systems.

Rebates are eligible to households when a solar hot water system is installed replacing an existing electric hot water system & many systems offer rebates in excess of $1,000 on the upfront cost of an average solar hot water system. For more information please see &
