Eco-Friendly Thermann Hot Water Systems — Save Energy & Reduce Bills
Thermann hot water systems are built for efficiency, reliability and everyday performance — so your home or business gets consistent hot water while using less energy. Upgrading to a modern, eco-efficient Thermann system improves performance, lowers your running costs and supports long-term energy savings.
Whether you run on gas or electricity, or want the efficiency of solar or a heat pump, there’s a Thermann system to suit. Our local team helps you choose the right model for your household, then installs it properly and to code — and we’re here afterwards for service and repairs.
The Thermann Hot Water Range
Thermann covers every type of hot water — from gas continuous flow that heats on demand, to solar and heat pump systems designed to cut your energy use. Here are the systems we most often install across South-East Queensland.
Thermann C7 Continuous Flow
Compact gas continuous flow that heats water on demand — endless hot water with nothing stored or reheated.
Thermann R-Series Continuous Flow
Reliable gas continuous flow sized for busy family homes and higher hot-water demand.
Thermann G-Series Continuous Flow
Gas continuous flow built for consistent temperature and efficient everyday use.
Electric-Boosted Solar
Roof-mounted solar collectors with electric boosting for cloudy days — free energy from the sun.
Integrated Heat Pump
Energy-efficient heat pump (such as the 285L) that draws warmth from the air to heat your water.
Electric Storage
Simple, dependable electric storage hot water for homes and sites without a gas connection.
Choosing the Best Thermann System for Your Home or Business
The right Thermann system comes down to a few things: how many people use hot water in your home, whether you’re connected to gas or running on electricity, and whether you want the extra savings of solar or a heat pump.
Larger households and higher demand often suit gas continuous flow for endless hot water, while a heat pump or solar system is ideal if cutting running costs is your priority. Not sure which way to go? Call us on 1300 728 122 and we’ll give you honest advice for your place.
