Which Hot water system is best?

With so many options available, we know buying a solar hot water system is really confusing.
So, to help you decide which system is best, we will walk you go through the solar hot water system types available.

Firstly, it’s important to understand – How does a solar hot water system work?

Solar Hot water system consists of collector panels and a storage tank. Solar collector panels installed on the roof absorb sunlight to heat water which flows into the storage tank. The process actually works by heating the water inside the collectors. The collectors can be Flat plate.

Solar flat plate collector systems are simple, cost-effective, and durable. They are easier to install in a ‘thermosiphon’ and ‘split’ configuration.

Evacuated tube collector systems are more efficient but expensive. They are ideal for colder climates. They mostly come as a ‘split-system’ meaning collector tubes on rooftop and tank on the ground. A pump is used to circulate the water.

*In thermosiphon solar water heater models, both collector panels and storage tanks are mounted on the roof. When water heats up it rises to the top of the collector and colder water flows into the bottom of the collector where the process repeats itself and water circulates on its own. So, no pump is used to circulate the water.

Next comes the choice of boosters –

Solar Hot water system with Gas Booster or Solar Hot water system with the electric booster?

The storage tank usually has an electric or gas booster element to keep the water hot on days with less sunshine. The selection of Gas booster or electric booster totally depends upon personal choice but it is advisable to go with an electric booster if you want to move away from gas altogether.

A very common thought which crosses the minds of almost all people – Do solar hot water systems work in winter?

The answer is yes, you will be surprised to know that solar hot water systems work well even in cold temperatures. Evacuated tube collector systems are considered ideal for colder climates. Apricus solar hot water system’s unique design and superior insulating properties, the system does not need any added compounds or chemicals to protect against freezing. You can read the details of how they work here.

Heat pump Hot water system

Heat pump Hot water systems extract heat from the air and use it to heat the water in the tank. To understand the working of a heat pump, imagine a refrigerator working in a reverse mode. A heat pump takes the heat from the surrounding air and transfers it to water in an enclosed tank. It is usually installed outdoors in a well-ventilated area. The technology of heat Pump is so advanced that it makes efficient use of the heat even at low temperatures. Have a look at enviroheat heat water pump.

Benefits of Solar Water Heating


Reduction in Energy Costs

As we know domestic water heating draws a large amount of energy to meet the needs. In households, we rely on hot water to run washing machines, dishwasher, steam baths, showers and many more. This increases the electricity bill and hence our expenses. Fortunately, our Hot water systems meet approximately 90% of the needs.

Adds value to your property

Solar water systems are gaining popularity worldwide especially in Australia. SWH increases the worth and desirability of your property.

Helps in saving the Environment

Global Warming has become a serious concern all over the world. SWH significantly reduce the dependency on fossil fuels and helps in lowering the carbon footprint. It saves money in the long run as sun’s energy is available free of cost.

Government support

Considering the benefits which the SWH offers, the government is offering attractive rebates to encourage people to switch to it.

Safe and reliable

When Solar water heaters get installed, they have very low maintenance. They come with comprehensive warranties to prove their reliability.

Efficient Technology

Technology has made a significant shift and nowadays it offers some SWH units with drain-back technology which uses antifreeze fluid to prevent freezing of pipes in cold weather.
