Types of Solar Hot Water Systems

Homeowners have a lot of options when it comes to solar. You’ll need to make two decisions:

  • Collector type - Flat plate collector vs. Evacuated tube solar panels
  • System type - Thermosiphon vs. Pump

Collector Type

Flat plate collectors are the most common collector type. They are airtight boxes containing water pipes, and are the more affordable choice. 

Evacuated tube solar panels are tubes made of glass with copper pipes inside. A vacuum is created when air is evacuated out of the pump which reduces heat loss. These tend to perform better in colder months – but in Australia flat plates are just fine. 

System Types

Thermosiphon Systems: The collectors and storage tank are combined into one unit installed on the roof. Water circulates passively between the solar collectors and tank using gravity and convection. No electricity is required.

Split Systems: These have roof-mounted solar collectors that heat water during the day. An electric pump actively circulates the hot water into an insulated ground tank. They are more complex but very efficient.

Our experts will inspect your home and help determine the best collector type and if a passive thermosiphon or active split system is the best solar hot water setup for your needs and budget.

Electric and Gas Boosting

Most solar hot water systems use a booster as a backup heat source for sunless days. We offer:

Electric boosted systems - Use an electric heating element in the storage tank
Gas boosted systems - More energy efficient as they heat water on demand

Our plumbing specialists will advise you on the best boosting method for your home.

Solar Hot Water System FAQs

How does a solar hot water system work?

Solar hot water systems typically use roof-mounted solar collectors to heat water during the day. This heated water is then stored in an insulated tank and available when you need it. Solar systems utilize the free and abundant power of the sun!

Does solar hot water work at night or on cloudy days?

The insulated storage tanks retain heat effectively overnight. Gas or electric boosters will heat the water when solar gain is low. Fortunately, Brisbane has over 280 sunny days per year.

Why should I pay more for a solar hot water system instead of a standard water heater?

Though a solar-powered system costs more upfront, they last longer and offer a significant savings on energy bills.

How long do solar hot water systems last?

With proper installation and maintenance, solar hot water systems can last 15-20 years.

What maintenance do solar hot water systems need?

Minimal maintenance is required. It's recommended to replace ancillary components like pumps and thermostats every 10 years. Solar collectors are self-cleaning with rain.

Does solar hot water work in winter?

Yes, solar hot water works year-round in Australia. Performance reduces on shorter winter days but boosters provide ample backup heating.
