Understanding your home's water supply is crucial when choosing the right shower system. The cold mains supply is a common setup where water is delivered directly from the mains without being stored or heated beforehand. This article provides an overview of how cold mains water systems work, their impact on shower performance, and the best shower options for homes with this supply type. Whether you're looking to upgrade your bathroom or simply want to understand your water system better.
You will know you have this system if you don’t have stored hot water at all, or don’t want to use up all your hot water when you have a shower.
If you do not have or want to use your stored hot water then an ideal solution is to fit an electric shower to the cold mains supply. The benefit of an electric shower is that it is always ready to use as the water is heated instantaneously within the shower. The amount of hot water flow produced by an electric shower depends on the power rating measured in kilowatts (kW). Kilowatt (kW) ratings in electric showers determine both the power and water pressure, meaning a higher kW rating provides a stronger flow at your desired temperature. For more information on our electric showers, please check out our electrics showers range. View our simple guide, we'll decode the kW shower ratings so you can confidently choose the best fit for you and your home.
How to turn water off: in the absence of a local isolation valve, turning the main stop cock for the property off will turn off the cold water. If you are unsure then speak to your plumber or installer.
Most mains water supplies will provide enough pressure to operate an electric shower. In the rare instances that it cannot then Mira has an alternative pumped electric shower. This must be fitted to a cold water tank (cistern) supply and the internal pump will then generate the pressure normally provided by the cold mains. View the Mira Elite Pumped Electric Shower to find out more about this alternative product.
