Why Green Energy?

With years of experience and hundreds of installations across Western Australia, GEWA offers you piece of mind when it comes to selecting the right brand and product for your home.

Tank Type

GEWA offer both stainless steel and vitreous enamel lined tanks, in closed coupled or split system format. Whilst in most cases both tanks can be used in residential applications it is important for our staff to assess which is suitable for you.

Collector Type

Flat plate collectors or gas evacuated tubes is a common question. Are the tried and tested flat plate collectors as efficient as the highly marketed gas evacuated tubes and what is most suitable for our climate? With the ability to supply both we will provide you with a non-biased approach to selecting the most efficient type for your budget.

Booster Options

The back up to the solar hot water system can be either electric or gas, not all options are viable, whether you have the infrastructure in place or are specifically looking to make use your solar power system, we can advise you of the benefits and most appropriate ways to use either back up for those months when the solar radiation is reduced.
