Mira Escape Electric Shower

Most showers have three power levels; low supplies cold water only; one heating element is switched on for medium power and two elements are switched on for high.

A multi-mode showerhead allows you to vary the type of spray depending on your needs. The standard options include a needle or jet flow, which gives a stimulating shower and a champagne or soft flow, which is ideal for a relaxing, luxurious shower but newer shower-heads may also feature a pulse motion, which gives the effect of a massage.

High-end models will have thermostatic controls installed to prevent water temperatures from fluctuating should someone draw off water elsewhere in the house and high-end models remember the preferred temperature setting of different users. Also some electric showers can offer cooler showers than others, which might be of benefit during the summer.

The average flow rate on electric showers is approximately 5 litres per minute in summer and 4 in winter, but it can vary from 1.5 – 8.5 litres per minute depending on the model and the temperature selected. In response to our need to conserve water newer models also feature a water-saving mode, which further reduces the flow rate.  Pumped electric showers use more water than non-pumped version, up to 10 litres per minute more so factor this in when making a decision on which model to go for.

Electric showers are normally sold in 8.5, 9.5 and 10.5 kW models but 7.5 and 10.8 kW versions are also available. Naturally the more powerful the model you have the more powerful the shower and the larger the electricity bills.

Noise levels can vary from 55 – 67 decibels, which may be a factor particularly if the shower is being installed in an ensuite.

The temperature control on an electric shower is normally a dial control, which should offers a good grip, be easy to turn and be clearly labeled. On older models the on-off switch was combined with the temperature control but on newer models a much more user-friendly push on-off control is the norm.

Ideally an electric shower should cut-off before the water reaches 46 degrees celsius but some showers cut out at higher levels than this so aim for a model with the lowest cut off temperature available.

Some models have a phased shutdown, which prevent the build-up of limescale by running cold water through the head before turning off or a removable lime scale traps which will help extend the life of your shower.

A shower with a long riser-rail makes it much easier to adjust he showering height to suit children and adults.

Some models are designed with a separate control unit from the one that heats the water. This means the control unit is smaller and can be mounted in the shower, whereas the heating unit can be installed in an airing cupboard or under a bath.

Electric showers require both electricity and water to operate so factor the cost of both an electrican and plubmer into your installation costs. Also the installation times will differ for different models so take this into account when choosing your shower model.

Electric showers should be fused separately at the fuse board either with a 40A or 35A cartridge fuse. Sometimes old electrical distribution boards have to be upgraded before in order to accommodate the power usage of modern electric showers. You electrician should also fit a  pull-cord operated isolation switch in the bathroom itself.

Electrical showers should never been plumbed to the mains and they need to be earthed.

As a general rule you cannot have two electric showers in a house without installing a second water tank.
