Solar Water Heaters in Kenya: prices, types and installation costs

The heating of water consumes a lot of electrical energy, and in a bid to save on costs installation of solar water heaters is the way to go. Solar water heaters in Kenya aim at promoting the use of clean energy and also reducing electricity costs by up to 55%.

Types of solar water heaters in Kenya

The most common types of solar water heaters in Kenya include:

Vacuum tube solar water heater

Also known as evacuated tubes solar water heaters, these are the most efficient collectors available. Each evacuated tube is similar to a thermos in principle. A glass or metal tube containing the water or heat transfer fluid is surrounded by a larger glass tube. The space between them is a vacuum, so very little heat is lost from the fluid. Since heat loss due to convection cannot cross a vacuum, it forms an efficient isolation mechanism to keep heat inside the collector pipes. These collectors can even work well in overcast conditions and operate in temperatures as low as -40°C. Vacuum life varies from collector to collector, from 5 years to 15 years. With this solar system, you can heat water to a temperature of up to 100 degrees with ease.

Flat plate Solar Water Heaters.

Flat plate solar water heaters typically consist of copper tubes fitted to flat absorber plates. The most common configuration is a series of parallel tubes connected at each end by two pipes, the inlet and outlet manifolds. The flat plate assembly is contained within an insulated box, and covered with tempered glass. Its design allows water circulation through its collectors and stores it in the tank. Because of selective coatings introduced in flat plate collectors, the undynamic fluid temperature can reach 200 degrees.


Prices of solar water heaters in Kenya range from 50,000 to up to 200,000 depending on the brand and the type of solar water heater whether its flat plate or evacuated tubes, pressurized or non-pressurized system.


Installation of Solar Water Heaters in Kenya is guided by the Energy Regulatory Committee (ERC), thus it is important that your installation is handled by an individual with the certifications required by ERC. It is required that a hose that consumes more than 100Litres of hot water a day install a solar water heating system . Solar water heaters installation cost varies from company to company ranging from 10,000 to 30,000. some company charge separate fees for installation whereas in some company the installation cost is factored in the the systems price thus when you purchase the company handles the installation.

Before doing the installation it is important for a technician to do a site visit which aims at establishing the amount of hot water that is needed in your homestead and thus recommend a capacity that is suitable for your needs. During the site visit it is also important to establish the best position to place the solar water heater ,this is the position in your house that get direct maximum sunlight.

When buying a solar water heater, determine which system will be ideal for your home. Consider one that will help to reduce energy bills at home and offer services for longer. Also, the solar water heating system will require regular inspection and maintenance. Therefore it is important to work with a certified professional who will handle such jobs on your budget.
