Water heating — compare the options

Hot water heating accounts for around 30% of the average household energy bill, so choosing the right system for your needs can make a real difference, especially on your wallet.

Whether you are replacing an existing water heating system, building a new home, or just doing some research, this tool will help you compare your options.

You’ll be asked a number of questions about how you use hot water in your home and you’ll get a comparison of the upfront costs (purchase and installation), annual running costs, and lifetime costs of different types of hot water systems.

So, grab your power bill (you will need it), make yourself comfy and let’s get started.
