Planning around power supply
Power supply is a real part of the decision in Nigeria. A good storage heater keeps water warm for hours thanks to its insulation, so you can heat when you have light and use the hot water later. If you run on an inverter or a small generator, tell us — an instant heater draws a lot of power while it runs, and a storage heater may suit your system better.

Installation tips
- Fix storage heaters to a strong, solid wall — a full tank is heavy.
- Use PPR pipes for the hot water lines, and fit the safety valve that comes with the heater.
- Make sure the heater is properly earthed and wired by a qualified electrician.
- Use a mixer at the shower and basin so you can blend hot and cold water.
Getting the temperature right
A water heater works best with a mixer at the shower or basin, so you can blend hot and cold water to a comfortable temperature. Set the heater’s thermostat to a sensible level — very high temperatures waste power and can scald, especially for children and elderly family members. If you choose a piano-key shower with digital display, you can see the water temperature as you shower.
Signs your water heater needs attention
- It takes much longer than before to heat up.
- The hot water comes out brown or rusty.
- You hear popping or rumbling from the tank — often a sign of sediment build-up.
- There is water leaking around the tank or valves.
- The breaker trips when the heater is switched on.
Switch the heater off and call a qualified plumber or electrician. If it is time to replace it, we will help you choose the right size.
Protect your heater with a water filter
Borehole water often carries sand, rust and minerals that shorten the life of heaters and taps. A water filter and replacement cartridges keep your water cleaner and your heater working longer.
