Frequently Asked Questions

Grid electricity is not only a scarce resource in Kenya, but it is also costly, unreliable and continually increasing in price. Solar, on the other hand, is a free fuel available for all to use, and it is Green! The Government has recognized this and provided for recent regulation which requires that all consumers of Hot Water in excess of 100L (a home accommodating more than 2 people) use Solar Water Heaters. This not only serves to free up Electricity for other consumers, but also allows for you, the consumer, to save significantly on your electricity costs, with immediate effect. All consumers must comply by 2017, while new construction must comply with immediate effect.

After installing our high-efficiency Solar Hot Water system, a typical household using a conventional electric hot water geyser will save upto 60% from their monthly Power bill. This means that you should recover your investment over 2-3 years of savings from your monthly Power bill.

The system is basically made up of the Tank and the Collectors. The Tank is comprised of the inner and outer layers, separated by a highly-effective, heat-insulating material; this ensures that all hot water in the tank stays hot for a long period of time. The Collectors are high-efficiency vacuum tubes, whose inner layer traps heat from the sun via a triple-absorption coating. The absorption coating in turn transfers heat to the water. This heat is prevented from escaping by a vacuum in between the double-layer coaxial glass structure of the tube - making the complete system highly efficient.

The basic working principle is known as the thermosiphon effect. Warm water rises due to natural convection, resulting in water circulating between the collectors and tank. The system is installed at an angle with tank above collector. As water in the collector tubes is heated by the sun, it becomes lighter and naturally rises into the tank above. Simple, effective and efficient, with no mechanical parts - this is the beauty of the basic system which has very few components which are prone to failure.

We will conduct a site visit to determine how best to fit the system. However, for a dwelling which already uses hot water, we do not expect major plumbing works. Nor do we expect major structural works, since the system typically sits on your roof, which we neatly integrate into various types of roof structure.

When heated by the collector tubes on a sunny East African day, the water temperature will rise to approximately 65 degrees Celsius. Moreover, we provide our customers with an Intelligent Controller, fitted in your home. This will give you full control over the system, showing exact temperature of the water. It also allows you to pre-set a preferred Constant Temperature - the Intelligent system will trigger the integrated Electrical Heater to boost your water temperature on cloudy days.

Indeed, you will. Hot water in the tank is kept hot thanks to the highly-effective, heat-insulating material between the inner and outer layers of the tank; this ensures that all hot water in the tank stays hot for a long period of time. Depending on your usage pattern, you will be able to set the system to automatically boost the temperature of the water, should the need arise.

The rate at which water is heated mainly depends on how hot it is on a particular day. However, one key benefit of our Solar Water Heaters is that there is 1 vacuum collector tube dedicated to heat every 10L of water. This means 30 tubes in the 300L system. Therefore, heating is evenly distributed along the entire length of water in the tank. The system has tubes with a combined collecting surface area of 3.7m2. To put this in perspective, a conventional electric geyser has 1 or 2 heating elements with a combined heating surface area of less than 0.2m2 (approximately 18 times less than the solar area).

The temperature of hot water depends on the rate of heating and the rate of use. If the real East African sun is out, you can continuously use hot water as fresh water is heated by the collectors on the go.

All our systems come with an Integrated Electrical Heater to boost your water temperature on cloudy days. We also provide our customers with an Intelligent Controller, fitted in your home. This will give you full control over the system, showing exact temperature of the water, allowing you to choose when to manually boost the temperature. It also allows you to pre-set a preferred Constant Temperature - in this way, the Intelligent system will trigger the integrated Electrical Heater automatically.

Our system typically integrates with a feeder tank, which serves as both a buffer for water supply and a cold reservoir to the Solar Hot Water system. The feeder tank gets its supply from your main reservoir (on ground, underground or from a water tower) in a similar manner by which your existing service tank is supplied. As long as there is water in your feeder tank, you will have uninterrupted supply of Hot Water. If the feeder tank runs dry, you will need to replenish it from the main tank (much in the same way as you need to replenish your service tank). This is mostly achieved by manual pumping, but we could offer the option to automate this pumping function via the Intelligent Controller.

This is a misnomer; and to show you our commitment, we will replace broken tubes free of charge. (Terms and Conditions apply - see our TITAN Assurance and TITAN Warranty for more information)

Contact us today for your free site assessment and estimate, based on your current plumbing, number of people at home and structure of your roof. We promise you the best price for quality and peace of mind in town.

We have an arrangement with several major local banks who will gladly offer you a reasonable payment plan.

Limited maintenance is required on the system, depending on your usage and the type of water you use. Contact us today for your free site assessment and estimate, including maintenance contract.

The system is designed for a lifetime of 15 years. We offer you a manufacturer defect warranty of 3 years, provided the system is installed by us, or by an installer who is certified by us.

All our systems come with an Intelligent Controller, fitted in your home. This will give you full control over the system. One of the many functions provided for is automated water top-up. In this way, your tank is guaranteed to always have the recommended amount of water and hence the system will be in safe operation mode.

We'd be happy to address any other questions you might have, so please call us today. We look forward to serving you!
