Any solar water heater's engine is the solar collector. Solar vacuum tubes have traditionally been the most efficient solar power generation devices, but they have also been the most costly. However, the rising demand for solar energy, along with current manufacturing processes, has brought down the cost to the point where vacuum tube technology offers the highest return on investment when compared to any other solar collector system.
Testimonials
Excellent service from start to finish even after my Solartech water heater was delivered and installed by all Sofo Soler staff. First purchase so I had a lot of questions that were answered in a clear and professional way before, during and after my purchase, I insist because often the after-sales service of certain companies leaves something to be desired. Best wishes !
FAQ
Frequently asked questions about solar water heaters.
Solar Water Heater
When water is delivered to your house from a solar installation through gravity, pressureless solar water heaters are labeled as 'low' pressure. This implies that no matter the pressure coming into the system, it will still flow out of the outlet by gravity and reach your house.
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.
No. If you don't want, for any reason, to drill on your roof, you might need to have some concrete slabs ready before the installation of the solar water heater. Our technician installs the blocks, and adjusts the distance and orientation of the solar water heater. Because Mauritius lies in the Southern Hemisphere, the solar water heater must face north for best performance.Â
In this case, if there is no water coming in, there will be no hot water pouring out of the outlet. However, our high-pressure system may operate at both low and high pressures at the same time. How? The drain is connected to the hot water outlet. When there is no pressure coming in, hot water from the main tank begins to flow in gravity from the drain over the same pipe network. You will then have hot water in your showers/baths as usual but with gravity. As soon as your pump is operational again, your system will resume normal operation.
Yes. In that scenario, a survey by our technician is required. Moreover, depending on the change to the metal support, the purchaser may indeed be charged an extra fee.
No, a system that has been self-installed is not covered by our warranty.
The continual flow of water in the system causes corrosion, which leads to the failure of the solar water heater. Dry out the heater while not in use to maintain it rust-free for a longer length of time. Because of the collectors' continuous use, vegetation growth and dust accumulation might become a source of worry. As a result, it must be cleaned on a regular basis. This shall be undertaken by a highly qualified person with experience in solar water heaters. Contact us if you need more assistance.
Our technician will have to replace the broken tube. If water is pouring out of the system, please close the intake and exit valves and notify us as soon as possible so that your system may be repaired.
Because each installation is unique, determining an exact cost is difficult; nevertheless, plumbing materials/fittings and labor may cost approximately Rs 2,500 or more. We may be able to assist you if you require a competent plumber for your piping work.
The first to do is to check if the ballcock shaft is broken. You simply need to open the cover on top of the small tank, open your cold water inlet and lift the stainless steel ball to test if it closes the valve. If water keeps going in, then you'll need to replace the ballcock. Here is the link if you need to order:www.sofo-soler.mu/products/ballcock
