Shower timer savings

Shower timer

The table below shows the average savings that could be expected by using a shower timer to reduce shower lengths from an average of 7 minutes to an average of 4 minutes.

Households without a water meter will save on the energy used to heat the water while those households that are metered will also save on water costs.

As you can see, the savings are substantial – and not just in financial terms, as there is also a reduction in the carbon footprint.

In summary, a shower timer will pay for itself within a few weeks. See our range (requires login) or buy online in our consumer shop.
