What is Solar Water Heating?
Solar water heating is using a solar thermal collector to convert solar energy to heat energy, which can heat the water instead of using conventional electric or fuel energy. It makes use of the free solar energy, and also contributes to a green environment.
Solar water heating systems take advantage of the free heat supplied by the sun to warm domestic hot water (DHW). These solutions provide DHW throughout the year, and they can be supported by boilers or immersion heaters to ensure you have hot water whenever you need it.
If you are planning to replace your existing boiler and already have solar panels on your home, many of our products are designed to support the use of energy from these panels to supplement your heating with a completely natural, green energy source. We also offer a range of solar collectors, and if you are investing in a new heating system, we advise you to consider designing it from the outset to incorporate these collectors. We provide evacuated tube and flat plate collector systems, both of which can be mounted on your roof.
Taking advantage of this renewable energy technology will help you to lower your consumption of mains energy, which in turn will reduce your fuel bills and cut your carbon footprint.
Why Solar Water Heating?
Water heating accounts for a substantial portion of energy use at many residential, commercial, industrial and institutional facilities. Solar water heating systems, which use the sun’s energy rather than electricity or gas to heat water, can efficiently serve up to 80% of hot water needs – with no fuel cost or pollution and with minimal operation and maintenance expense.
Solar water heating systems can be used effectively throughout the year at facilities that have an available installation area with un-shaded / little shaded for solar collectors. A variety of building types can take advantage of solar water heating systems including residences, hotels, hospitals, school dormitories, prisons, factories. Solar water heating system are the most cost effective for facilities with the following characteristics:
- Water heating load is constant throughout the year
- Water heating load is constant throughout the week (will use solar hot water every day)
- Cost of fuel used to heat water is high (electricity, gas, diesel etc.)
- A clear sunny blue sky (helpful but not necessary clear, overcast is OK)
