Solar Hot Water

Solar hot water systems absorb the energy from the sun to heat water. The system consists of solar panels and a storage tank. The average four person household usually requires 2 panels and a 300-360L tank.

System types

Roof Mounted (Thermosiphon) System: A thermosiphon system has both the collector panels and storage tank mounted on the roof. The water in the panels circulates into the tank via the thermosiphon effect (as water heats up, it becomes lighter and rises into the tank).

Pump or Split System: Pump systems have collector panels on the roof however the tank will be installed at ground level. Hot water is pumped from the panels to the tank. A pump or split system solar hot water unit will use more power than a roof mounted option as the pump will be running for the duration the system is heating the water inside it.

STC (Small-scale Technology Certificate) financial incentive

Most solar hot water and heat pumps are eligible to a number of small-scale technology certificates (STCs) provided they are listed on the Register of Eligible Solar Water Heaters.

Solar hot water systems should run without issues and not require more maintenance than a regular hot water system. Having an issue? We are happy to spend the time to discuss your requirements and provide you with a tailored, cost effective, efficient solution.

  • Jadair was very prompt in responding to my initial inquiry. They were extremely helpful with their advice with Troy emailing us and following up with phone calls to discuss various options and prices. Their service was prompt and very efficient. I was amazed at how they did the site inspection, report and installation in just 2 working days. We are so pleased with their service. We highly recommend them and would not hesitate to use their services again.

  • Jadair put in a Daikin 12.5Kw ducted system for me (7 zones) and I couldn't be happier with the service and install. Getting a full quote and plan was easy and all my questions were answered fully, so I was confident in choosing the best set-up for for my family home. Installation was professional, on time, clean and without any incident. The boys arrived early and were fully done by mid afternoon, having fully cleaned up after themselves. I'm definitely happy to recommend Jadair.

  • Jadair installed our ducted air conditioning system several years ago, and have performed the annual maintenance ever since. The installation itself and subsequent performance have been problem free, efficient and effective. The technicians installing and servicing the unit are both knowledgeable and obliging. I heartily recommend Jaidair..
