FAQS

Martyn Brown, Contract and Technical Manager at Triton Showers, answers two of the most frequently asked questions he receives during his working day.

> QUESTIONS

1How much flow can I expect to get from an electric shower?

Martyn says: The performance of all temperature stabilised electric showers is governed by the following factors; kilowatt rating of the shower, water temperature entering the shower, voltage to the shower and the preferred showering temperature.

At a showering temperature of 38°C an electric shower will deliver 2.5 to 3.5L per minute in winter, increasing to 5-10L per minute during the warmer months. The higher the kilowatts, the greater the flow of water for the desired temperature selected.

2What is the minimum water pressure requirement for an electric shower designed to connect onto the mains cold water supply? Martyn says: Electric showers require a minimum operating pressure in order to activate switches controlling heating elements in the unit. A minimum flow at that pressure is also required for optimum temperature control and performance. Requirements differ for the wide range of showers on the market. Always check the manufacturer’s specifications.

If mains cold water supply doesn't provide adequate pressure and flow, an electric shower can be connected to a cistern fed pumped supply.

> PRESSURE AND FLOW REQUIREMENTS:

8kW and 8.5kW showers: 1 bar minimum running pressure at a minimum flow of 8L per minute 9kW and 9.5kW showers: 1 bar minimum running pressure at a minimum flow of 9L per minute 10.5kW showers: 1.5 bar minimum running pressure at a minimum flow of 11L per minute.
