The technology is simple and effective and the benefits are huge!

I can wholeheartedly recommend using Pete from Plumb Solar – he has taken care of the plumbing in my home for over 7 years. He offers excellent service, he comes when he says he will and I absolutely trust him to get to the bottom of what needs to be done and fix it – all at a great cost!

When I needed a new roof, he also took care of that – which was an easy and painless task, again at a great price.

If you’re in need of a plumber, you can’t go past Pete from Plumb Solar!

Save 70% on your power!

Hot water can represent 40 to 70% of your family’s power bill. In the last five years energy costs have soared a massive 48 percent, with more rises still to come.

1How does a solar hot water system work

Solar collector(s) are located on the roof structure, facing in a northerly direction. The sun heats the water in the collector, which then goes into a tank.

The hot water rises naturally in the tank – this process is called thermo-siphoning. This water is then made available to the house, either through a gravity feed or a pump.

The colder water at the bottom of the storage tank then travels into the collector and starts to heat up. This process is a continuous cycle.

2 How long does it take to install a system?

It depends on what type of system you are installing, but installation generally takes between two and four hours.

3What maintenance is involved?

A solar hot water system is almost maintenance free. Rainfall will keep the collector clean; a quick wipe down is all that is needed should you notice dust or dirt build up.

4Can solar hot water be used in cold conditions?

Yes. A Plumb Solar hot water system can be used in temperatures as low as -30deg Celsius, although performance is reduced in such extreme conditions. Good heat output is still achieved in mild sub-zero conditions.

5Will water be heated on a rainy day?

Yes. Although the efficiency of the solar collector is reduced on overcast days it will still be able to heat water for normal use. If it is a heavily clouded day or raining, then gas or electric backup may be required to maintain water at the required temperature. This system will be automated so you don't have to worry about running out of hot water on a rainy day.

6What happens if I go away for a period?

The system will continue automatically and autonomously manage itself while you are away. The power supply to the pump should be kept on, or else damage may be caused to the solar collectors.
