All about Solar Water Heaters in Kenya

Water heating demands a lot of electric power, so installing solar-powered water heaters is the best option to cut costs. In Kenya, solar water heaters work to reduce power prices by a higher percentage while simultaneously enhancing the use of renewable energy.

These arethe most influential collectors on the market; they are also called evacuated tubes solar water heaters. Each evacuated tube functions conceptually like a flask. A bigger cylinder surrounds a glass or metal tube that houses the water or heat transfer fluid.

There is a minimal heat loss from the water because there is no air between them. Since it cannot navigate a vacuum, convection is an efficient isolation approach for keeping heat within collector pipes.These collectors can function in temperatures as low as 40°C and even in cloudy conditions.

To make flat-plate solar-powered water heaters, copper tubes are commonly connected to flat insulation layers. The most common design consists of input and output funnels connecting a set of parallel pipes at both ends. Tempered glass protects the flat plate component, which is housed in an insulated compartment.

Because of how it is made, water can circulate through the collectors and be stored in the reservoir. The flat plate collectors’ selective sealants allow the un-dynamic liquid temperature to rise to 200 degrees.


Solar water heater prices in Kenya depend on the product and type of solar water heater—flat plate, evacuated tubes, pressurized or non-pressurized system.

Pressurized and non-pressurized solar-powered water heaters are the two primary kinds you will find when selecting solar-powered water heaters. The methods used by these two systems to heat and distribute water in the home are different. Therefore, it is essential to consider which of these two solar water heating systems is best for your requirements.

Pressurized and non-pressurized solar water heater

The two major types of solar heaters are pressurized and non-pressurized models. These types employ various techniques to heat and distribute water for domestic usage. It is important to consider which of these solar water heating systems will suit your needs the best.

A pressurized device needs pressure to send water throughout the house. Moreover, the water shutoff is, therefore, under pressure, which could reduce its lifespan. This technique might deliver hot water at a regularly rate as compared to non-pressurized heaters.

Furthermore, because the system is independent, one can place the tank at any area of the house rather than only at the highest elevation.

The most prevalent solar-powered water heaters you will encounter are non-pressurized models. This is so because the installation process is straightforward and requires little upkeep. You won’t need to inspect most of the non-pressurized heaters periodically. If you fully comprehend the system, you could even test it yourself. As a result, the system’s operating expenses are reduced.


Compared to their pressurized equivalents, non pressurized solar water heaters are more cost-effective. You should consider the non-pressurized system if you’re on a tight budget.

Additionally, the non-pressurized heater is quite effective. It utilizes a non-pressure water shutoff, extending its lifespan compared to a pressurized system with numerous potential failure points.
