O'Brien Electrical & Plumbing Warrnambool

The boys are on-site in Warrnambool today completing a two-storey solar installation and there’s no carrying solar panels up ladders on this job!

Instead, we’ve brought in the big guns 💪 with a telehandler from Hire Australia doing the heavy lifting and getting the panels safely up to roof level.

When you’re working at heights, having the right equipment makes all the difference. It means less manual handling for the boys, a safer way to get the panels where they need to go, and a much easier day on the tools!

Hydronic power flush
🚨 THIS is what was hiding inside a customer's heating system. 🚨
Take a look at the colour of the water from a recent power flush — all that black sludge, rust and debris was circulating through the pipes and radiators, making the system work harder and heat slower. 😮
A hydronic power flush clears it all out, restoring your system to full capacity so every room heats faster, more evenly, and more efficiently.
❄️ And right in the middle of winter is the perfect time. Your heating is working its hardest, so don't let a clogged system rob you of warmth (and waste money on your energy bills).
✅ Faster, more even heating

✅ Improved efficiency = lower running costs

✅ Longer lifespan for your boiler & pump

✅ Fewer cold spots and breakdowns
📞 Get your system running at its best this winter — message us today to book your power flush.

Hydronic Power Flush System!
🔥 Just in time for winter! 🔥

We’re excited to have just taken delivery of our brand-new Kamco Hydronic Power Flush System!

Our old machine had served us well over the years, but it was time for an upgrade. This new unit allows us to continue providing professional hydronic heating system maintenance to homes and businesses across South West Victoria.

Did you know that your hydronic heating system should be power flushed and treated with fresh inhibitor chemicals approximately every 3 years?

Over time, sludge, rust, and debris can build up inside the pipework, radiators, and components of your system. This can lead to:

Reduced heating performance
Higher running costs
Increased wear on pumps and components
Cold spots in radiators
Reduced system lifespan

A professional power flush helps remove this build-up, restores efficiency, and protects your investment for years to come.

With winter now here, there's no better time to make sure your hydronic heating system is operating at its best.

Give our team a call today or book online to arrange a hydronic system inspection and power flush.

Regular maintenance keeps your system running efficiently, your home comfortable, and helps protect one of the biggest investments in your property.
