The rise in power bills makes electricity consumers think of alternative energy for homes and businesses. The option is tapping solar power. In a country with plenty of sunshine use of solar water heaters is not yet widespread. This article gives information on how a solar water heater works.
An increase in electricity bills and frequent power outages are making Kenya consumers go for solar products as alternative ways to heat water in homes and business premises.
Solar water heaters come in different makes and models. The Kenya market offers a wide range of this product. The consumer picks what is efficient and durable from so many makes and models in the dealer shops. The market is awash with heaters and other solar gadgets. Some of them are not of quality, and consumers need to understand first how to tell the good from the fake.
Getting the best
The Kenya Government directed that businesses and residences that consume over 100 liters of water daily install solar water heaters. Probably not many people have heeded the directive, but with time, it may become a reality.
Fortunately, the Kenya Bureau of Standards (KEBS) and Energy and Petroleum Regulatory Authority (EPRA) certify the heaters and the licensed dealers, respectively.
It is also prudent for consumers to buy solar water heaters in Kenya that bear ISO Certification.
Consumers should buy fromreputable dealers who have a license and are likely to stock good-quality solar heaters at prices they can afford.Such dealers have in store a variety of heaters with different capacities. EPRA-licensed dealers often benefit from government subsidies which they pass to their customers.
Reputable dealers offer free delivery within certain mileage limits. They have qualified technicians who do the free installation and after-sales services and carry out affordable maintenance and repair services.
Types of solar water heaters
Solar water heaters in Kenya come in two main categories. Depending on how they work, they are either direct or indirect heaters.
In the direct heaters, the solar energy collectors on the rooftop have tubes that heat water. Solar energy heats the water and circulates it to the storage tank. The description of the water loop system is another name for this action.
In the indirect system, the solar energy heats the liquid that releases heat energy to the water in the tank.
The two systems can be either active or passive. The active system uses pumps to circulate water or the liquid that transfers solar energy from the roof collector. The advantage it has is that the heater temperatures remain stable.
The passive system does not use pumps. It depends on convectional currents and gravity to move water to taps.
