Solar is Stellar: Solar Water Heaters for Households

durable solar water heatersIt’s green, it’s clean, and it’s unlikely to run out. Solar power is the most cost-effective and viable source of energy that plays an important role in the world’s power infrastructure.

The use of solar hot water systems can be an affordable way to produce hot water by using the sun’s energy. These come in a variety of designs, all including a collector and storage tank.

How solar water heaters work

Solar hot water systems for households use solar panels or collectors installed on your roof. These collect heat from the sun and use it to heat water. Homeowners often back the collectors with a boiler or immersion heater to reach the temperature they prefer.

Flat Panels vs. Evacuated Tubes

Flat panels are made from copper pipes that run through a glass-covered collector. The most common setup is a series of parallel tubes connected at each end. Solar panel contractors often connect these panels and tubes to a water storage tank on the roof, siphoning the water in and out of the tank, thus heating the water.

Evacuated tubes, on the other hand, use a glass tube with vacuum and copper pipes that run through the centre. This system can capture the heat of the air on a humid day and don’t require direct sunlight, making it ideal for a typical Australian household.

Maintenance costs and savings

While the costs of installing solar water heaters are a bit costly, the expenses will surely pay off when you install one for your home. Most solar heaters come with a 5 to 10-year warranty and require little maintenance from professional contractors. This leads to more savings on your energy bills, giving you enough financial resources for other household expenses.

Water heating is one of the largest sources of greenhouse gas emissions from an average Australian home. By using solar water heaters, you’re effectively using Australia’s abundant sunshine to save money and energy, and protect Mother Nature.
