A 'Triton Electric Shower' is a shower that can draw on a cold water supply and heat it on demand. It differs from other showers in the fact that it can use cold water and heat it itself, instead of relying on a boiler to heat the water first.

A ten minute shower can use less water than a full bath. With a new 2.5 gallon-per-minute (low-flow) shower head, a 10-minute shower will use about 25 gallons of water, saving you five gallons of water over a typical bath. A new showerhead also will save energy — up to $145 each year on electricity — beating out both the bath and an old-fashioned showerhead. To avoid moisture problems, control humidity in your bathroom by running your ventilating fan during and 15 minutes after showers and baths.

Electric showers only take water from the mains cold water supply. They heat the water when you turn the shower on, by passing it over a heating element inside the shower - in a similar way to how a kettle works. When you shower, you don't use up and stored hot water - so electric showers are ideal for families and households where there is a limited supply of hot water. Electric showers are always ready to use, any time of the day or night
