PCT No. PCT/NO97/00027 Sec. 371 Date Oct. 21, 1998 Sec. 102(e) Date Oct. 21, 1998 PCT Filed Jan. 31, 1997 PCT Pub. No. WO97/28410 PCT Pub. Date Aug. 7, 1997A solar collector having a radiation absorber (1) has a number of channels for conducting heat receiving liquid, said channels accommodating particles for capillary effect to lift the liquid to effectively sweep the sun-facing surface layer of the absorber. The solar collector is started after a prolonged operation standstill by driving a liquid pump (7) intermittently by a control unit (13) acting according to a clock-controlled program. In the intermittent start-up phase, first the pump (7) is driven for 2-4 minutes, thereafter it is shut down for a time span of about 20-60 seconds, and this is repeated two or three times before a continuous operation phase is started. Thereby air in the absorber (1) channels is expelled more rapidly.
