Do you want an electric or a mixer type of shower or should you opt for a thermostatic one instead. What you need will be different from what another person needs. The best way to figure this out is by understanding better what each type of shower is and how it benefits you.
Mixer showers, as their title suggests, mix cold and hot water from your hot water boiler system to warm or cool the water to your required temperature. Generally speaking they are normally very fast flowing compared to electric showers. You can even add a bit more oomf to the flow by using a separate pump. These type of showers are best suited to thermal and un-vented store systems and combination boilers and are often installed into new builds. Although you can use a pump with them they are unnecessary. If you already have a mixer shower and are looking to replace it, we would advice that you opt for a thermostatic mixer shower as this controls the temperature of the water with far greater accuracy, to about 1 to 2 degrees of the desired temperature. It should be noted though that when it comes to younger and older ones using this type of shower, there is the built in safety feature that the hot water stops flowing completely if there is no cold water flowing for one reason or another.
Electric showers, as mentioned across this website a few times, take the water directly from your mains cold supply. They heat that water by passing it over a specially designed heating element inside the shower in a similar fashion to how a kettle warms cold water. Electric showers are therefore the perfect choice for households with only a limited supply of hot water and where there are many people looking to use the shower at the same part of the day. No matter what time of day you decide to use them, electric showers will always be ready to use.
Venturi Showers, Jetstream Etc
This is perhaps the least common type of shower listed on this page and it is one that does require an electrical connection or any pumps connected to it and can work from a gravity-fed hot water system or a cold mains supply. The pressure and velocity of the cold water passed through the special venturi nozzle creates something similar to a suction effect and pulls hot water into it from the household hot water cylinder. The shower system then mixes the hot water and the cold together in the valve or the showerhead so that it sprays down onto you at the desired temperature. Any variations in pressure or temperature of the incoming cold water are reduced in the mains cold water pressure which reduces the suction of hot water and this helps to keep the temperature of the shower as stable as possible.
Digital Mixer Showers
As you have guessed by the name, digital mixer showers are a type of showers that mix hot and cold water and feature controls for the user on a wireless connection. There are generally two different versions of the mixer, a mixer valve unit for use with combi boiler systems and high pressure water supplies and a pumped shower version to boost the gravity fed system.
If you are looking for a safe and comfortable shower for the whole family, you and old, you should give careful consideration to thermostatic showers. Thermostatic showers work very much in a similar way to mixer and electric showers in that you have control over the temperature, but with even greater accuracy than those two put together. For this reason thermostatic showers are often known as care showers, because they are used in care homes as well as domestic homes.
There you have it, a rough guide to the most common types of showers you can have installed in your home. As we like to remind you again and again, the choice you make should be the right choice for you, but if it was up to use to decide we would suggest electric or thermostatic. Electric showers are perfect for the average home because they give you enough control over the temperature and are always ready to use, because they work using the cold water supply, whereas thermostatic showers obviously benefit the more sensitive people in society, from the very young, to the very old and infirm.
