Thermann continuous hot water systems never run out of hot water which makes them a great choice for even the busiest households. They only heat water as necessary and are a very energy efficient option. Sizes are based on litres per hour from 16L to 32L for domestic and 28L to 50L for commercial.

Price point: Between $800 and $1,850 (unit only)

How it works:


Thermann hot water storage systems include gas or electric storage systems and heat pumps. Electric storage systems can be installed inside or outside (gas systems outside only) and come in a variety of sizes – from an under sink 25L unit to a massive 400L unit with twin elements.

The Thermann Electric Heat Pump uses the same fittings as a standard electric hot water system and are an environmentally friendly choice, as it provides great reductions in greenhouse gas emissions. Heat pumps extract heat from the surrounding environment and use it to warm water in a tank. By utilising the ambient air temperature, they can achieve a high level of energy efficiency.

Price point: Between $400 and $1,550 for hot water storage systems and between $3,000 - $3,250 for heat pumps (units only)

How it works:


Thermann solar hot water systems are the future of hot water – they are highly efficient and help reduce your carbon footprint. Instead of traditional panels, Thermann offer Evacuated Tube Solar hot water systems. The technology has been around for over 50 years so it offers proven reliability and excellent efficiency.

Solar hot water systems come with both gas and electric back-up units with internal elements in the storage tank to ensure peace of mind. You’ll never be without hot water even though you’re relying on the heat of the sun to predominantly keep your water hot, There are significant costs upfront for the installation for the different elements - storage tank, solar panel collector - but in the long run, they are the most energy and cost efficient option.

Price point: Between $4,350 and $7,500 (units only)

How it works:


How do I get a hot water system installed?

Your new hot water system should only be installed by a licensed plumber. If your old hot water system is being replaced, the plumber will be able to disconnect the old tank, drain it out, wheel the new one in, connect and fill it.
Prices for installation vary based on the type and size of the hot water system, if you will be installing it inside or outside, if your house is single or double storey (for solar hot water systems) and if any additional plumbing needs to be done as part of the installation, such as installing a new gas line.
