Hot water

This is often the silent and hidden energy user. When was the last time you attended to your water heating system? Where are your heaters - on the roof, under stairwells, in cupboards or outside? How many heaters are installed and what points do they supply?


If too large, energy will be wasted by heating more water than required. If too small, running out of hot water may affect business.


Ensure the water heater is close to the main point of use - if not, remember this when you decide to replace the heater. Short water supply lines reduce water heating requirements.

Dripping taps

Replace washers - ninety drops per minute will waste approximately 1400 litres of hot water per month.
