The Pros And Cons Of Gas Boosted Solar Hot Water Systems

As solar is already an attractive alternative to traditional water heaters, you’d think it couldn’t get any better. Well, it can!

By boosting your solar system with gas, hot water will always be readily available, come rain, shine, or night time. It acts as a supplemental water heater to ensure you get the most out of your solar hot water system.

Before looking into upgrading your current hot water system, do yourself a favour and get to know the benefits of gas boosters. You won’t regret it!

To help you make your decision, we’ve compiled the most notable pros and cons of gas boosted solar hot water systems.

Gas Boosted Solar Hot Water System Pros

Significant savings

As solar systems use the sun’s natural rays as a source of free energy, installing one could slash your monthly energy bills in half. In fact, solar systems can pay for themselves within six to ten years!

Nowadays, the STC rating of most gas boosted solar water heaters is actually the same as for electric boosted solars, and even less for some brands. Therefore tested and deemed by the CER to be no cheaper running costs. Because solar gas boosters have to be set to heat the water coming from a solar HW tank to 70C and therefore use a shit load more gas than when used as a separate stand alone continuous flow gas HWS.

The best part? Gas boosters are easily retrofitted onto solar storage tanks and quickly increase their efficiency.

Better together, whatever the weather

Whether you’ve used up your sun-heated water or there was no sun to begin with, you’ll always have hot water. Once your gas booster detects a drop in water temperature, it’ll automatically ignite to provide instantaneous heating.

Environmentally friendly

Going solar helps you protect our planet, as it offers renewable, clean energy. On the other hand, conventional hot water systems generate heat by combusting fossil fuels. This produces harmful greenhouse emissions, pollutes the air, and contributes to climate change!

Gas Boosted Solar Hot Water System Cons

Initial upfront installation costs

The costs involved can make any homeowner think twice about getting the system installed. However, it’s important to remember that in the long run, your system will pay for itself!

Fossil fuel combustion

Unfortunately, a gas booster involves fossil fuel combustion and may not be the best choice for die-hard environmentalists. But, all is not lost! Natural gas is one of the cleanest fossil fuels available, producing 50-60% less greenhouse gas emissions than the rest.

Now that you’ve seen the evidence, you can make an informed decision for yourself!

Testimonials What our
Customers Say

I have given Kalamunda plumbing 5 stars but only because I couldn’t give them 6!Kalamunda Plumbing we’re absolutely fantastic! I had a burst pipe somewhere on my property (3000 sqm) leaking at 1L per second. I tried 4 different plumbing companies before coming across Kalamunda plumbing. The first company made me wait two days and then forgot my booking, the next one couldn’t help me for over a week and the last quoted me $1200 for the job and still had to wait three days. I called Kalamunda plumbing and they arrived the very next day. Anthony found the burst pipe within 20 minutes to the exact location, dug down and repaired the leak. The whole job only took 2 hours and was 1/3 of the price I was quoted.They were professional, helpful and friendly. I will now be a customer for life. I have shared my experience with all that I know in my area.I cannot recommend them highly enough. Thank you for everything! When the need arises I will be back!

craig mccullough
We had a large amount of water bubbling up between the pavers down the side of our house. After a quick call around and a few dead ends I got hold of Kalamunda plumbing. They were able to have someone around quickly, dig down and repair the broken water line. Saving me a fortune in wasted water. Highly recommend and definitely will be using for any future plumbing work.
Trent and Barry from Kalamunda Plumbing did an excellent job. As well as fixing the problem in a timely manner, they gave me some good advice on a number of other potential plumbing issues
Roger Barnett
One thing that I really appreciate is a tradesman that arrives when they say they will, especially when you have taken time off work to have your hot water system replaced.Kalamunda Plumbing were on time and I can't believe how quickly the work was done, and at a reasonable price considering that they did an urgent repair for me. Everything was back to normal again so quickly, mess cleaned up and they adjusted the water temperature so that it was not hot enough to scold me.Well done to everyone involved at Kalamunda Plumbing, greatly appreciated.Regards Russell
