Solar water heaters

We make high quality evacuated tube solar collectors for water or room heating during the summer. Our water heaters are made from stainless steel, which makes them durable and they pay for themselves within 2-3 years. The installation of the solar powered water heaters is very simple, and can even be performed by people with limited plumbing experience. On the other hand, it can also be left to specialists.

The main features of our water heaters:

  • The cheapest way to install a complete solar thermal collector system.
  • Can be connected to combined or electrical water heating.
  • The connection is made using plastic or multi-layered pipes.
  • Stainless steel inside, outside and construction.
  • Small electricity consumption (from 0 to 30kWh per year).
  • Evacuated tube solar collectors.
  • Stainless steel heat exchanger.
  • Easy lime scale removal from the heat exchanger.
  • Can be easily and cheaply protected from freezing.
  • Does not require (unnecessary) a circulator pump.
  • Microprocessor control.
  • Can be expanded with and electromagnetic valve.

Northern Europe has enough solar power

Solar collector – a device used to collect solar power via the visible and infrared light. Solar collectors are used to heat water, rooms and pools. Since solar collectors absorb energy, which is carried not just by the visible light, but also infrared light, they work even when it is cloudy. That is why water is heated when there are no direct solar rays. The amount of sunshine depends on the time of year – in the summer it is larger, while in the winter it is smaller. In the months of May – August, the solar energy is completely enough to sustain the energy requirements needed to heat water.

Long term studies have shown that the average amount of yearly solar radiation, which hits the horizontal surface in Lithuania, is about 1000 kWh/m2. This is almost the same level as is in Denmark and more like Sweden, where solar power usage is extremely popular. This amount of solar energy is enough to be able to effectively use solar collector systems for the heating of water in a household. This can save 50-60 percent on expenses used to heat water throughout the year.

88 percent of the yearly solar energy, that falls perpendicular to the Earth’s surface, falls in a period of 7 months – March, April, May, June, July, August and September. This kind of spread of solar energy lets us adapt the work of solar collectors with the seasonal heating of buildings – during winter, hot water is gained via the central heating system of each individual home, during non-seasonal heating times – from the sun. Daylight hours are longest in coastal areas and get shorter the closer you get to the eastern border. The average amount of daylight hours in coastal areas is roughly 1900 hours each year. In the eastern region of the country it does not go over 1700 hours. Nida has the largest amount of daylight hours in total.
