The method includes generat ing a signal in the presence or absence of an indicia of water flow associat ed with the water heater; initiating operation of a pump associated with the air handler when the signal indicates that water flow associated with the water heater is at least at a selected level to supply hot water to the air han dler sufficient to generate heated air; and/or terminating operation of the pump and/or a blower/fan associated with the air handler when the pres ence or absence signal indicates that the water flow associated with the wa ter heater is less than the selected level. -T 26 14 - 24 - 20 - 32 - 44 43 -- - - -- - - - - - -j W O 2 0 0 8/13 4 3 4 1 A 3 II1IlII|I|1VlI|IlIllIllIllllII|I||||||| I||| III|||||||I||||||||||I||||||I|I|I|||||||||||| Published: (88) Date of publication of the international search report: - with international search report (Art. 21(3)) 19 January 2012 - before the expiration of the time limit for amending the claims and to be republished in the event of receipt of amendments (Rule 48.2(h))
