Solar Water Heating Systems

Solar hot water units are investments of a lifetime, with a solar hot water unit, electricity savings can be as high as 85% and the more you use it the more the savings. The systems are available in different designs and specifications for commercial/institutional or swimming pool heating.

The system consists of a heat collecting panel and an insulated water storage tank. During the day, the sun shines on the solar panel heating the water. This water rises into the tank because of the principle of thermosiphoning which also causes a displacement effect in the tank. The cold water inside the tank flows into the heat collecting panel to get heated and this process gets repeated until all the water gets heated up. This water is stored in the hot water tank for use later. (This water is available hot the following morning)

Did you know;

• Solar water heating is one of the most practical and proven technologies of utilizing the sun’s energy
• Has zero running costs, offering better value for money
• Is unaffected by power cuts
• Require minimal maintenance
• It taps a safe, clean Inexhaustible energy source

Solar energy helps protect the environment from pollution and damage that other heating can cause, but did you know that unless your solar hot water system is efficient and durable you could be paying unnecessary electric/wood booster costs.

Solar World offers a wide range of solar heating solutions no matter your climatic conditions or area you are leaving in. We have solar systems designed to meet the water conditions and your family’s usage.

Talk to our experts about your family needs and we can workout the best way to help you save up to 95% on water heating costs. Solar World also utilizes the evacuated tube technology for solar water heating systems, this is a well proven water heating technology.

Economic justification of solar water heating
Employing solar energy makes a great deal of economic sense. Research indicates that 50 – 80% of all household electricity bills are consumed by water heating.

Assuming an average electricity bill for a small household consuming 60 gallon of hot water per day; economic projections are as follows (for water heating per month).

Consumption (units)
Cost per unit
Other charges
Total cost per month     300
6.58/-
2,400/-
4,374/-

This translates to an average monthly water-heating bill of KShs 4,374 or KShs 52,488 per year.

A solar heating system of 60 gallon will cost approximately Kshs145,000. If one chooses to install this, it means that there will be a payback period of only two years and a seven months after which the system will effectively be earning the owner at least KShs 50,000 every year!

Why pay more when you could have your solar heater running on absolutely free energy from the sun?

Life Expectancy
Our systems have an expected lifespan of 20 years with minimal maintenance. Our guarantee on the system is 5 years.

For commercial/institutional applications, the system is configured after a site survey.
