Choosing a Water Heater: Size, Type and Safety Basics
Capacity, installation space and safety features matter more than looks when you buy a water heater.
A water heater serves the whole household, so it helps to decide a few things before you buy.
Capacity. Think about how many people use hot water and how many bathrooms and taps are in use at the same time. A small tank is enough for a kitchen or a single basin, while a family bathroom usually needs a larger tank. Ask us if you want a suggestion for your home.
Type. Electric storage heaters are common and simple to install. Gas heaters and instant heaters work differently and have different installation needs. Choose the type that matches the energy source available in your home.
Space and mounting. Measure the wall or cabinet where the heater will go, and make sure the wall can carry the weight of a full tank. Leave space around the heater for maintenance.
Safety. Look for a heater that has a thermostat and a safety valve, and have it installed by a qualified technician with correct earthing and water connections. Never use a heater whose safety parts have been removed.
Care. Follow the manufacturer's instructions for maintenance and have the heater checked from time to time, especially if you notice leaks, strange noises or water that does not heat properly.
