Solar Hot Water
The sun radiates an immense amount of energy to the Earth. The solar radiation on the globe for one hour would be enough to meet the annual worldwide energy demands! A solar water heating system saves energy, reduces utility costs and produces clean energy.

How does solar hot water work?
A solar system captures solar radiation through a solar collector. A heat transfer fluid inside the collector heats up and is pumped to a heat exchanger where the absorbed heat is transmitted to the drinking water or heating circuit. The cooled heat transfer fluid is pumped back to the collector and the cycle is repeated. Depending on your current hot water heating system, there are two primary ways of the integrating a solar hot water system. A solar preheat system which feeds preheated hot water from a solar tank into your existing hot water tank. Or a dual-coil single-tank system (as illustrated), where the hot water is heated by both the boiler and the solar collector.

What can I use it for?
Solar collectors are ideal for heating your domestic hot water – the hot water use to take showers, do laundry, etc. In some cases, solar energy can be used, together with a low-temperature hot water heating system, to support your space heating load, or for pooling heating.

How much can I use?
An efficient solar heating system will make the best use of whatever sun is available. To produce heat the sun doesn't have to shine brightly. A parked car, for example, warms up on a cloudy day. Solar collectors work much the same. Highly-efficient collectors can utilize even the smallest amount of solar radiation. Evacuated tube solar collectors are specifically designed for northern climates, and can produce enough solar energy to heat up to 70% of your annual hot water requirements. Based on hot water requirements of an average family household with a 2-collector system package.

How much can I save?
The amount of available solar radiation is dependent on the time of year and your location. The solar coverage rate measures the average amount of energy covered by solar system in a year. In northern climates, solar coverage can still be as high as 70%. In the summer months a high-performance solar system typically covers almost all the energy required to heat domestic hot water. Solar hot water can make a real difference. Not just by reducing your energy bill, buy by reducing harmful CO2 greeenhouse gas emissions as well. |
