How does a solar water heater work?
Solar water heating systems, also known as solar thermal systems, use solar energy to heat water for storage in a hot water cylinder or thermal store. Because the quantity of accessible solar energy changes throughout the year, a solar water heating system will not deliver all of the hot water needed. To make up for the shortfall, an immersion heater is typically used.The solar collector is made up of open vacuum tubes that capture solar energy from the sun's rays and convert it to heat energy.
When the cold water comes into touch with the energy generated, the water inside the vacuum tubes warms up.
The density of the water inside the tubes lowers as it heats up, and the hot water rises into the hot water storage tank.
The cold water in the tank will flow down into the tube due to its higher density.
The entire procedure is repeated, and the hot water will circulate constantly until the temperature of the water within the hot water tank reaches the temperature of the water inside the vacuum tube.
The thermosiphon cycle is the name given to this natural phenomenon.

High pressure solar water heaters work similarly to the low-pressure model except for the fact that they will provide much more water pressure in your showers and taps. The most commonly used model in Mauritius is the heat-exchange.
Our models has 2 cold water inlet and a single hot water outlet as shown in the picture. the output water pressure is determined by the feeding pressure of the water pump.
A high pressure solar water heater (pre-heated) is generally supplied by a cold water pump. The hot water storage tank is fed with cold water and is heated by the vacuum tubes (same working principle as the low-pressure).
Hot water is kept inside the storage tank and water pressure coming from your water pump (1HP recommended power) will go through the copper coil found inside, which will then be heated by the hot water in the storage tank. The hot water coming from the coil will have the same pressure as the cold water, which is then supplied to your shower/taps.
The hot water tank is made up of 3 layers; the inner tank which is used to store hot water (made of stainless steel 316L), the foam of 55mm thick used as heat insulator that can store hot water for 3-4 days and the outer tank made of stainless steel 304.
Hot Water Tank
The mounting frame is made of re-inforced aluminum 2.5mm thick with a layer of anti-corrosion coating to improve the durability and strength, all fixed using stainless steel bolts & nuts
Copper is thermally efficient and durable heat exchangers. Cold water flows inside the copper coil, which is heated by the hot water found in the hot water tank.

Thank you for the excellent service. Overall, your price is unbeatable when compared to other companies which are offering same product at higher prices.I have received the product on time and the installation also went well. Therefore, got no complaints at all!! 🙂🙂I highly recommend your company to other clients..
Thank you Cedrick for sending your maintenance team to repair my Solar hot water system. Danny and his team replaced the heating element. They were polite, professional and compitent, and provided good advice. I will use your final in the future.
Excellent service du début à la fin même après la livraison et l'installation de mon chauffe eau Solartech par tout le personnel de Sofo Soler. Premier achat donc j'avais énormément de questions qui ont étaient répondues de façons claire et professionnelle avant, pendant et après mon achat, j'insiste car souvent le service après vente de certaines entreprises laisse à désirer. Bonne continuation !
Solartech 240Lts High-Pressure
240lts can offer adequate water for a household of 4-5 people, as well as your kitchen faucets and lavabo. The important flow of cold water pressure necessitates a high flow of hot water, which requires a high-pressure system.
Price includes VAT, transport and installation
