9 short questions that could save you a fortune.
It is wise to ask the seller and installer as many questions as possible before you commit to buying any solar hot water system. Below are 9 things you need to know about evacuated tube solar hot water systems.
- What is the optimum pitch for evacuated collector tubes if installed in the Canberra region?
The answer should be – 45 – 55 degrees from the horizontal for all brands and models of evacuated tubes. This can double winter efficiency and increase the life of your system.
- Which tanks are best suited to the Canberra region?- Stainless steel or Glass lined / enamel lined steel tanks?
The answer should be – Glass lined / enamel lined steel tanks, unless you are using bore water. We don’t have corrosion issues as much as we have expansion and contraction issues in this region.
- Is it best to have a larger storage tank or a smaller storage tank?
The answer is – Always larger is best. Storage tanks are like batteries. The bigger they are the more solar hot water they can store. Therefore, the less boosting they require.
- What are the benefits of delayed boosting on electric boosted solar hot water systems?
The answer is – To minimise boosting in winter, and to take as much energy from the sun as possible during daylight hours.
- Can I use a single power circuit for the booster and for the control station?
The answer should be – Definitely not. One reason is that the electrical load could keep tripping your booster circuit. The second reason is that if your booster circuit has tripped you will have no electronic frost protection for your manifold and flow and return pipes. You will have no solar gain either.
- Which is best, gas boosting or electric boosting in the Canberra region and why?
The answer should be – Electric boosted solar hot water is best. If installed properly an electric boosted solar hot water system can be cheaper to own and operate than a gas boosted system. Repairs and maintenance will be easier too. Gas boosted systems are best for off grid situations or when there is extremely high hot water use.
- What licences and qualifications do installers have to have?
The answer should be- An installer should be a licensed plumber first and for most. Electricians are by law not allowed to install solar hot water systems. If you are buying a gas boosted system the installer should have a gas fitting licence too. An electrician is only required for the booster circuit, delayed booster and power point for the control station.
- Does the seller sell other brands and models of hot water systems?
The answer should always be – Yes. Additionally, the seller should personally have experience in installing and repairing all types of hot water systems. This ensures that you are more likely to get real unbiased advice from a real solar hot water expert.
- Who repairs the systems you sell and install?
The answer should be – We repair and service the solar hot water systems that we supply and install. However, your warranties will not be affected if you use another qualified solar hot water repairer.
