What does your hot water system actually cost?
The upfront price is only part of the picture.
Different hot water systems come with different installation costs, annual running costs and energy use. A system that costs less to install isn't necessarily the cheapest to run over time.
We've put together this comparison using figures from EECA to show how hot water heat pumps, electric hot water cylinders and gas continuous flow systems compare.
The figures are a general guide only. The right option for your home will depend on things like your household size, water pressure, property type, available space and how much hot water you use.
