How much is the electric water heater price in nigeria for a 15-liter storage tank for residential bathrooms?

I am tired of boiling water on the gas cooker every morning before taking a bath, especially during the cold harmattan season. I want to install electric water heaters in my two bathrooms. I believe a 15-liter or 20-liter storage tank should be sufficient for a standard shower. What is the current water heater price in nigeria for reliable brands like Ariston, Thermocool, and Midea? I have heard that some cheap water heaters can be dangerous and cause electrical shocks if not properly installed. What safety features should I look out for when buying, and is it better to buy a storage tank heater rather than the instant shower head heaters?

For residential bathrooms, the water heater price in nigeria for a 15-liter storage tank usually falls between 75,000 and 100,000 Naira. Ariston is the most trusted and dominant brand in Nigeria. A 15-liter Ariston water heater costs about 90,000 Naira. It uses a very thick titanium enamel tank with thick polyurethane insulation. This means if you heat the water at 6 AM and turn off the switch, the water inside the tank will remain scalding hot until late in the evening. Thermocool and Midea are excellent alternatives in the 75,000 Naira range. 15 liters is perfectly adequate for a single person taking a bucket bath or a quick shower. If you have a bathtub that you intend to fill, you must buy a 30-liter or 50-liter tank, which costs upwards of 130,000 Naira.

Regarding safety and the water heater price in nigeria: Water heaters combine water and high-voltage electricity, making them potentially the most dangerous appliance in a home. Never compromise on installation. A storage tank heater is much safer than an instant shower head heater because you can heat the tank, switch off the electricity completely at the wall, and then bathe with zero risk of electrocution. When buying, ensure the heater has a "Thermostat Cut-off" (which stops heating when the water reaches maximum temperature) and a "Pressure Relief Valve." The pressure valve is critical. As water heats, it expands. If the thermostat fails and the water keeps boiling, the pressure relief valve lets steam escape. If this valve is missing or blocked by a bad plumber, the tank becomes a literal bomb and can explode violently.

I installed a 15L Thermocool heater for 80k in my guest bathroom. It heats water to boiling point in less than 20 minutes. It is very energy efficient if you turn it off immediately after the light indicates the water is hot.

Ensure your electrician installs a dedicated 20-Amp Double Pole switch outside the bathroom door for the heater. Never connect a water heater to a standard 13-Amp socket; it will melt the plastic socket and cause a fire.

Instant water heaters (the small boxes attached directly to the showerhead) are cheaper (around 35,000 Naira) but they require very high water pressure to activate the heating element. If your overhead tank pressure is low, they will not work at all.
