Solar Water Heaters in Kenya | Hot Water, Zero Electricity Bills – CoastalSolar Africa

A solar water heater is one of the smartest investments a Kenyan home or business can make, delivering consistent hot water while slashing electricity bills, especially in a climate as sun-rich as the coast. At CoastalSolar Africa, we stock genuine solar water heating systems suited to households, guesthouses, and small businesses across Mombasa, Malindi, Diani, Kilifi, and beyond.

Our solar water heaters harness free solar energy to heat water throughout the day, storing it in an insulated tank so hot water is available even after the sun goes down. Available in a range of tank capacities, these systems are built to serve everything from small family homes to larger households and guest accommodations, with reliable performance even during Kenya's cooler or overcast spells. Tank capacities include, 100L, 150L, 200L and 250L. 

Beyond water heaters, CoastalSolar Africa also offers solar installation, a full range of solar accessories, lithium battery recovery and repair, and inverter repair, whichever system you're running, we've got you covered end to end.

We deliver solar water heaters across Mombasa, Kilifi, Nyali, Bamburi, Shanzu, Ukunda, Watamu, and countrywide.
