Frequently Asked Questions

Although people are more knowledgeable about solar hot water systems than ever, there are still some questions we’re asked all the time. We’ve provided a brief answer to most of these below.

 

How does a solar water heater work?

There are different types of solar water heaters available, but essentially they all work by converting light into heat. When sunlight strikes the darkened surface of the solar collector panel, the visible and ultraviolet light (short wavelength) is converted into infrared radiation (long wavelength) through heat exchange. The glass panel above the collector surface along with other insulated materials traps the heat generated in what is essentially a miniature greenhouse. This heat is what warms the water.

 

Will I run out of hot water?

No. When you install the right unit with the capacity for your needs, you’ll always have hot water. In the case of unexpected heavy usage or periods of low solar gain, the booster will kick in to heat water.

 

How much can I save?

From an environmental perspective, you could help save the planet! Solar hot water systems produce the lowest greenhouse emissions and pollutant levels of any type of water heater. On average, swapping from to solar hot water will reduce your greenhouse gas emissions by 3 – 5 tonnes every year!

Economically, this will depend on where you live, water usage, the system you’re replacing, energy tariffs and the model you choose. The Federal Government estimates the average household will save approximately $300 per year on energy bills. Add eligible rebates and RECS to that and you can save money upfront as
well. Whichever way you look at it, your solar hot water system will recoup its installation costs during its service life.

Interestingly, nearly half of the respondents to a recent survey of homebuyers on realestate.com.au stated that solar heating and solar hot water enhance the value of a property.

 

What about rebates?

Yes, you can save even more. This site has a comprehensive rebates and incentives section on what rebates you may be eligible for when you install a solar hot water system including RECs (Renewable Energy Certificates).

 

Can you make solar hot water even more affordable?

EcoSmart have made it easy to buy a solar hot water system with Easypay. A 24 month no interest ever repayment plan to approved purchasers.

 

My hot water system just blew up, can I get a new solar hot water service today?

Yes! EcoSmart can make sure you have hot running water within 24 hours.

 

What about cloudy days, does solar still work?

Even on a cloudy day, the solar panels of your hot water system will still convert light into heat. On very cold and cloudy days or after extended poor weather, the gas or electric booster will automatically kick in, meaning you will always have hot water.

 

Do I have to have the tank on my roof?

Not necessarily. Most EcoSmart units are designed with the storage tank separate from the solar panels so your collector panel and storage tank can be in two different locations. Discreet and practical and you won’t need to strengthen the roof.
