Very high electricity bills and unreliability of power supply continue to be a challenge for Kenyan households. With solar energy as the new energy frontier,developers and home owners are now opting to use the energy in homes as it has proven efficient, cheap and reliable.
Choosing the right Solar Water Heaters Kenya for your house however may be a challenge for many. More often than not, solar water heaters do not last, not because they are not genuine but because the wrong systems are used for the wrong purposes. We at Seven SS Stars Kenya will always give you the right direction when it comes to purchasing a solar water heater for your home.
These are the factors to consider:,
1.Type and functionality
There are two types of solar collectors- Flat Plate Collectors (FPC) and the Evacuated Tube Collector (ETC). The FPC are made out of metals (majorly copper & or aluminum) and are more suited for tropical climates given their high conductivity and emissivity – this makes them poor heat retainers under low ambient temperatures.The flat plate are quite bulky and hence expensive compared to the vacuum tube solar water heaters. However, the Flat plate have an added advantage of robustness, durability and easy serviceability. The vacuum tend to have a higher heat retention capacity thus suitable for both tropical and temperate regions. However, since they are made out of glass they are quite delicate and should be handled with extreme care during installation, servicing and operation.
Both systems are suitable for used in either the open or closed loop systems. An open loop system is suitable for clean and soft water where chances of clogging and scaling of tubes circulating the hot water are minimal. Whereas the closed loop system is suitable for cases where there is hard water or one is unsure about the water source. A closed loop system uses different heating medium from the water in circulation that is a heat pipe for the tubes and the water does not go through the tubes or glycol for some flat plate systems thus does not mix with the water being heated .Our solar water heater systems come with a magnesium rod which aid when the water is salty and prevents corrosion to the water tank.
2.Number of users in the house;
On average, one person uses about 30 liters a day, therefore, in a household of three the water requirements is about 100 liters every day.
Therefore In smaller homes 150 litres to 200 litres can suffice as this serves between 2 to three people in a household, in larger however homes a 300 liter may be required as this serves an average of 5-7 people and for other uses such as kitchen and laundry areas. Industrial capacities such as hospitals and schools use larger systems ranging from 500 liters to 5,000 liters depending on needs.
3.The Water Source and pressure of the water
When purchasing and installing a solar water heater in a home, it is important to consider the pressure system in the house. The source of the water or where the tanks supplying the house with water dictate the pressure.
There are two types of Solar Water Heaters Kenya systems: the pressurized and the non-pressurized system. There needs to be a pressure equilibrium between the supply line and the solar water heating system. If you select the wrong application for the wrong system then it will obviously fail.
In addition to the pressure system, it is also important to know if the Solar Water Heaters Kenya system is on a pitched roof or on a flat environment as each requires a different kind of system to bring in good results. Because the pressurized type is a closed water tank, the tank tank is thicker, so it can be placed anywhere in the home, such as the bathroom or living room and one has to use a pump or high pressure to feed the tank. Because the non-pressure solar water heater is an open water tank, there are exhaust holes at the top of the water tank, and the outlet water is drained by gravity, so the water tank needs to be placed on the roof below the water source so that water can flow in easily with gravity such as a water tower.
4. Professional installation and after sale maintenance.
Just as it is important to purchase solar water heaters from reputable companies, it is also important to get professional installation. This ensures that the solar water heater works as it should and also stays longer.
It is also important for a developer or home owner to engage a solar company to offer after sales services including quick and timely responses to clients for troubleshooting. We at Seven SS stars Kenya offer professional installation and after sale services to our customers.
The basic steps in installing a solar water heater are first mounting the solar collectors on the roof or the ground, then installing the storage tank and piping and filling the tanks.
5. Reputable company and solar service life
Finding reputable companies to buy a solar water heater is the first step in getting genuine products because such products have been tried an tested and one can get testimonies from customers who have used the systems.
At Seven SS stars Kenya,our key selling point is the assurance of the service life of their products. Most of our clients are large organizations who want value for their money and providing solar water heaters that last long does exactly that.Our Solar water have a service life of 15 years and a five-year warranty as well as we have to match both quality and price.
Homeowners and developers should always check the warranty before purchasing a solar water heater and also need to know which system works for you; either the flat plate collectors or the vacuum tubes.
In conclusion we at Seven SS stars ensure the quality standards are maintained while carrying out our projects. We have areas with poor water quality i.e. salty and hard water, and because of our diverse product range we are in a position to advise our clients to purchase the right solar water heating system that will work for years.
