I. What are the characteristics of
With the use of conventional energy sources of electricity, gas and other water heater, solar water heater with a very significant advantage; safe, clean, energy saving, environmental protection – which is advertising and its penetration in the case at a distinct disadvantage, can rapidly diverted electricity, gas water heater market reasons.
Second, how to buy solar water heater
A good product should have a complete manual, warranty card, logo, packaging and other products look beautiful, reasonable structure, excellent selection, workmanship, and perfect after-sales service.
Third, how much water heater purchase
Generally takes about 35kg-50kg per person bathing water (45 ?). Unconventional because solar energy can not produce hot water in case the rain, so double the daily water demand to choose the water heater, hot water heat storage will be sunny to rainy day use. In case of two consecutive days, the choice of optical dual-use type, to ensure all-weather, all year has a hot water use.
Fourth, the choice of what kind of pipe
Often due to water heater on the roof, and inside there is a certain pressure, high temperature hot water in summer (up to about 90 ?), the outdoor temperature is low (up to -10 ? below), the actual situation, so the best selection of cross-linking tube or plastic or reinforced plastic composite pipe hose. With pressure, high temperature, low temperature, non-toxic and tasteless, small heat capacity, heat loss is small, easily damaged by frost in winter characteristics. Galvanized pipe heat capacity, heat loss, easy raw water rust, frozen pipes in winter, so should not be optional.
