Hot Water FAQs

For over 65 years, we have been setting the standard for solar systems in Australia. Our systems are designed for the harshest Australian conditions. Our solar power systems only use world-leading panels and the world’s best quality inverters. Our solar panels are consistent with Solahart’s quality and performance requirements, using state of the art PERC monocrystalline cells, designed to achieve excellent performance under real conditions, even with low radiation intensity and on clear hot summer days.

Because of their high efficiency and performance, Solahart systems deliver amazing savings. Replace your old gas or electric water heater with a Solahart Solar Water Heater and you could save up to 65%* of your water heating energy consumption. A Solahart Solar Power system can generate significant savings depending on the size of the system you select and your overall energy use, reducing your energy costs even more. Solahart Gold Coast will use the Solahart’s Savings Estimator technology which will calculate how much you will save by installing a Solahart system. The Savings Estimator will take you through some simple assumptions on your current energy usage patterns and site conditions to give you a good idea of how much you can reduce your energy bills.

By installing a solar water heater system on your property, you are most likely still eligible for STCs. These STCs can be used to reduce the purchase price of your new system and can often save you thousands of dollars.

For a Solahart Solar Hot Water system, each STC represents 1 megawatt hour (MWh) of electricity displaced over a 10 year period. The number of STC’s created varies with the size and model of solar water heater and the region (or zone) in which the unit is installed. The value of an STC is not fixed and varies depending on market factors.

Once you install a solar water heater, the STCs produced can be traded and sold on the open market. You can assign the right to create your STCs to your Solahart dealer who will pay you the value of the STCs as an upfront discount on your system.

The best Solahart unit for your needs will depend on the following key factors:
• The amount of available sun
• Is the area prone to frost?
• The water chemistry in your area
• How many people in the home & their typical hot water usage

To choose the best water heater for your family, please call us at Solahart Gold Coast. We will make an appointment for you to speak with an expert who will help you pick the right unit for your current and future circumstances.

Water heating accounts for around 25% of the average household’s energy usage. Getting your hot water free from the sun not only saves energy, it also saves the greenhouse gas emissions that would have been produced in the generation of that energy. By replacing an electric storage water heater with a Solahart you can reduce greenhouse gas emissions by up to 2.7 tonnes a year^, the equivalent of taking a small car off the road.

If your current hot water system breaks down Solahart Gold Coast can have you back in hot water within 24 hours in most instances.

All solar water heaters include a gas or electric booster switch to ensure you have hot water even during the colder, darker days of winter and on those occasional cloudy, rainy days. By selecting the right Solahart model for your area and your family’s hot water usage patterns, the use of the booster can be minimised.

Solahart’s range of Streamline Split System solar water heaters allows you to enjoy all the benefits of Solahart’s advanced solar technology – without the tank on the roof.

The Solahart Split System locates the low profile collectors on your roof, with the tank installed at ground level. Alternatively you can choose a Solahart heat pump which uses technology to extract heat from the surrounding air, without solar collectors at all.

Yes. We service hot water systems. It is recommended that hot water systems are serviced every 5 years to maintain efficiency.

Of course we service our Solahart products however we also service other brands including Rheem, Dux and Saxon. Get in touch regardless of which brand you have installed and we can help.
