Solar-powered heating systems are growing in popularity as governments encourage the transition from fossil fuels to renewable alternatives and consumers look for ways to reduce their energy bills. Similar to residential solar panels that provide electricity to consumers, solar heaters are being installed in homes around the world as part of private as well as government initiatives.
A solar water heating system includes a storage tank and a solar collector. There is Two types of systems available: active with circulation pump and control device, and passive without. There are two types of active solar water heating systems. A direct circulation system with a pump that circulates domestic water into the home through a collector, and an indirect circulation system with a pump that circulates the water. An antifreeze heat transfer fluid passes through a collector and heat exchanger to heat the water that enters your home. The latter works more effectively in cold regions than the former.
Passive solar water heating systems are generally less expensive than active systems, but they are not as efficient. However, they can be reliable and last a long time. There are also two basic types of passive systems. An integrated collector storage passive system has a storage tank covered with a transparent material that allows sunlight to heat the water before sending it to the plumbing system. A thermosiphon system works by heating the water in a rooftop collector when the hot water tap is opened, before transporting it to the plumbing system. Most of these systems have a 40 gallon capacity.
Because these systems rely on solar power, they typically require a backup system for cloudy days or periods of high demand. Backups can be made in the following formats Conventional hot water storage type water heater or as part of a solar heat collector such as a rooftop tank with a thermosyphon system. Solar water heaters require maintenance every 3 to 5 years, and some parts may need to be replaced every 2 to 10 years. Once installed, they can significantly reduce consumers’ energy bills, especially in areas with high solar radiation.
In Europe, Cyprus has the highest proportion of solar water heaters. The eastern Mediterranean island nation is taking advantage of its favorable weather conditions and deploying solar heating to support its green transition and help consumers reduce energy bills. Approximately 93.5% of households now use solar water heating, allowing Cypris to exceed its renewable energy targets for heating and cooling its buildings.
Mr. Sharalampos Theopeptu, Cyprus Environment Commissioner said“There are many regions in Cyprus that are not meeting their greenhouse gas emissions targets… However, in terms of renewable energy resources being used for sustainable heating and cooling of buildings, it is precisely thanks to the widespread use of solar power that I easily achieved my goal.”I have been using a water heater for years. ”
Cyprus has been using solar water heating since the 1960s and was ahead of most other countries. This technology became popular because it requires only solar panels, tanks and copper pipes, as well as suitable weather conditions. Cyprus averages over 300 days of sunshine a year, making it a perfect environment for technology. With the spread of solar heating, the domestic manufacturing industry has developed and many jobs have been created. Although installation costs are rising every year, there are subsidies available from the EU for households considering installing solar heaters.
Solar-powered water heaters have also become increasingly popular in the Middle East and North Africa region in recent years. In Jordan, Energy and Mineral Resources Minister Saleh Halabsheh in September launched the second phase of the government’s solar heating subsidy program, which covers 30% of costs. This scheme supports the installation of: 5,000 solar power systems cost up to $4.2 million. In the previous phase, 3,500 solar water heaters were installed.
In Egypt, 3 out of 4 households depended on butane cylinders Just a decade ago, there was little access to grid-connected natural gas supplies. In 2023, Egyptians consumed about 800,000 butane cylinders per day, many of which were subsidized by the government. For this reason, many households have been encouraged to invest in solar water heaters in recent years. Egypt solar water heater market in 2024 over $100 millionis rolling out the UNIDO-supported Solar Heating in Industrial Processes (SHIP) program. There are currently 11 solar heating manufacturing facilities in Egypt, and the government is looking to strengthen ties with Tunisia and Jordan to further grow the market.
The market value of solar water heaters is expected to increase from approximately $4.26 billion in 2023 to $4.26 billion in 2023. $6.18 billion by 2028the compound annual growth rate is 7.4 percent. Asia Pacific is expected to be the fastest growing region for solar water heating over this period. Industry growth will be supported by innovation, as companies bring predictive analytics and artificial intelligence to heaters to improve performance. The market is primarily driven by government policies aimed at transitioning from fossil fuels to environmentally friendly alternatives, national and local subsidies for disadvantaged communities, and increasing consumer demand to reduce energy bills. Probably.
