Thermann solar hot water systems are the future of hot water – they are highly efficient and help reduce your carbon footprint.

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. So even in days of low solar gain (cloudy days), the back-up booster system will help your solar hot water unit heat. 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.

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.
