摘要：<p>A solar water heater and a heat collection method for the solar water heater. The water heater comprises a plurality of vacuum tubes (1). A tubular water tank (2) is inserted in each of the vacuum tubes (1). Lower ends of the tubular water tanks (2) are sealed, and upper ends are all connected on a connection tube (3). The part between outer surfaces of upper ends of the tubular water tanks (2) and inner walls of upper ends of the vacuum tubes (1) are sealed. A solar energy selective absorption layer is disposed on at least one of the vacuum tubes (1) and the tubular water tanks (2). Two ends of the connection tube (3) are a water inlet (31) and a water outlet (32) of the water heater respectively, and are used for being connected to indoor tap water. According to the water heater, a water storage tank is replaced by using tubular water tanks (2) inserted in the multiple vacuum tubes (1), so that the water heater occupies smaller space and has a simple structure; in addition, cold water is heated in a manner in which cold water flows through the upper end opening of each of the water tanks (2) and is heated by hot water at the upper end opening of the water tank (2), so that it can be ensured that the temperature of outflowing water are not changed overall.</p>
