Why The L Series
The Classic Solahart, Refined
The roof-mounted Solahart is the system that made the brand famous, and the L Series 302LF18T is its most refined form yet. Australian made and proven over decades in the harshest conditions, it heats a 300 litre tank with free energy from the sun. For Rockhampton families, it is the flagship choice for serious hot water savings.
How It Works
Simple, Reliable Thermosiphon Design
Twin flat-plate collectors absorb heat from the sun and circulate water naturally into the tank above — no pumps, no moving parts to wear out. An electric booster covers cloudy stretches so you never run cold. It is a beautifully simple design that keeps working year after year in CQ conditions.

Still trouble-free after 22 years
All staff were friendly, helpful and prompt to respond. The installers were well-organised and careful despite difficult access through the yard.

Large solar system installed in one day
A very professional experience, from booking the install with Marty to the wonderful work done by Victor and his team. We are really pleased with the job and the fact it only took one day to install such a large system. If you are thinking about solar, do yourself a favour and go with Solahart.
Cameron Atkinson
Tailored to a pensioner budget
The tradesperson who assessed our home realised we'd be far better off replacing our old electric system with a Solahart unit that could cut our electricity bill by up to 75%, at a much lower cost. For a household surviving on pensions, that saving makes a huge difference to our budget.
Kevin Fox
Friendly service and a neat heat pump install
Great friendly service from the on-site quote right through to having our new heat pump system installed as soon as possible. The crew worked quickly and effectively, were happy to answer questions, and left a neat, tidy finish, cleaning up the site on completion.
Dean Stockham
Quoted and installed within the month
Got back to me within 24 hours of my online enquiry, came out and quoted the job, and had it done within the month. Cannot ask for anything better. Really happy with the work and the communication.

Quick response and action to the initial request. All staff were polite and considerate when turning off the water and power, with plenty of notice. Very impressive.
Vanessa
Faith restored with efficient service
My recent experience with Solahart was totally different to the past. They arrived when they said they would, assessed the situation and solved the issue. Mitch the plumber was easy to talk to, efficient and happy to explain what was done. My faith has been restored!
Sallie Matta
New owners fixed previous system issues
The new owners of Solahart have done an incredible job dealing with the previous owners' mistakes. They promptly arranged a technician to go over my system to check it was all working correctly, something I'd waited months for. Ken has been very genuine and kind to speak with. I'd recommend Solahart…
Jaquilyn Griffin
Urgent replacement completed faster than promised
This was a painless exercise. When I first contacted them for an urgent Solahart hot water replacement, they said it would take two weeks to order and install. When most people say two weeks they mean three, but they completed it in little over a week.
Karen D Richards

Coordinated trades replaced our system in two days
We recently had a solar hot water unit replaced, which involved replacing some roof sheeting in two sections of our roof. The work was carried out so efficiently there was no need for a temporary unit. The old unit was removed and the new Solahart unit installed within the same day.
