Why The Streamline
Solar Hot Water, Cleaner Roofline
Plenty of homeowners want solar hot water but would rather skip a tank on the roof. The Solahart Streamline 322MLV36 answers that: slim collectors gather the sun up top while the 300 litre tank sits neatly at ground level. You still get the free solar heating, with a look that suits modern Gladstone homes.
How It Works
Pumped Split-System Design
A small circulator pump shifts water between the roof collectors and the ground-level tank whenever there is solar heat going. An electric booster steps in on cloudy stretches so the hot water never runs dry. The 322MLV36 is Australian made and built for Central Queensland heat, humidity and storms.

Large solar system installed in one day
The whole thing was very professional, from booking the install with Marty through to the wonderful work Victor and his team did. We're really pleased with the job, and impressed that such a large system only took one day to install. If you're thinking about solar, do yourself a favour and go with S…
Cameron Atkinson
Tailored to a pensioner budget
When the tradesperson assessed our home, he realised we'd be much better off swapping our old electric system for a Solahart unit that could cut our electricity bill by up to 75%, and at a far lower cost. For a household living on pensions, a saving like that makes a huge difference to our budget.
Kevin Fox
Friendly service and a neat heat pump install
Great friendly service the whole way, from the on-site quote through to getting our new heat pump system installed as soon as possible. The crew worked quickly and effectively, were happy to answer our questions, and cleaned up the site on completion, leaving a neat and tidy finish.
Dean Stockham
Quoted and installed within the month
They replied within 24 hours of my online enquiry, came out to quote the job, and had it finished within the month. You can't ask for anything better. Really happy with both the work and the communication.

Nathanuel Holland
Amazing system that works perfectly
Two years earlier we'd put solar on another home and it was never a good experience. This time was amazing. It works so well and the installers were wonderful. All up an amazing company, and I'd use them again.

The new owners of Solahart have done an incredible job sorting out the previous owners' mistakes.

With the new owners, I'd re…
Jaquilyn Griffin
Urgent replacement completed faster than promised
The whole thing was painless. When I first contacted them for an urgent Solahart hot water replacement, they estimated two weeks to order and install. Most people who say two weeks really mean three, yet they had it done in little over a week.
Karen D Richards

Coordinated trades replaced our system in two days
We recently had our solar hot water unit replaced, a job that also meant replacing roof sheeting in two sections of our roof. It was carried out so efficiently that no temporary unit was needed. The old unit was removed and the new Solahart unit installed on the same day.
