A\nsolar collector can be used to heat water. The device installed on\nthe roof is often simple: a liquid circulates inside a dark panel\n(flat plate collector) or a series of tubes (vacuum tube collector)\nand is heated by the sun. The liquid is lead through an insulated\npipe to a backboiler, from which it can be used as domestic warm\nwater or as additional floor heating for a bathroom, for example. A\nsolar collector needs a backboiler to reserve warm water.<\/p>\n\n\n\n

With a solar collector, you produce up to 60% of the domestic warm water needed; all of the needed water in the summer and about half in the autumn. The 7\u201310 m2 collector is sufficient for a family of four. Solar collectors can be connected to a heating system to cover up to 25\u201335% of the heating need and more in passive and low-energy houses. The collectors produce most heat directed towards south in an angle of 30\u201360 degrees.<\/p>\n\n\n\n

Solar\ncollectors can be used in detached, semi-detached and apartment\nhouses, old and new, as long as there is a compatible backboiler\navailable. In new houses, a solar collector can be used to complement\na fireplace and an air-water pump in a hybrid system. In an existing\nhouse, a solar collector can be used to cut the emissions and costs\nof oil and electrical heating. If a backboiler needs to be renewed\nanyway, a solar collector is a sensible investment. The design and\ninstallation of a solar collector system require expertise.<\/p>\n\n\n\n

A\nsolar collector\u2019s technical lifespan is long, 30\u201340 years, and\nreturn from the investment can be expected in 3\u20137 years. The\ndimensioning and installation of a solar collector must be ordered\nfrom a professional expert including a warranty period. The equipment\nis rather low maintenance. After the pollen season, the collector\nneeds to be cleaned. If there is snow on top of the equipment, it\nwill melt as the system kicks off. The carbon footprint of the energy\nproduced with the equipment is very small, only about 10 g CO2<\/sub>\/kWh.<\/p>\n\n\n\n
