SYSTEM FOR HEATING AND 24 HOUR-BATH

摘要

PURPOSE: To reduce cost and save space by making a heating means to be sharable. CONSTITUTION: A heating service pipeline 5 is so formed that anti-freeze solution 3 in a fluid heating tank 1 may be circulated through a heating load 4. A space between a feed line and a return line is connected with a bypass circuit 7 having an on/off valve V1 and a heat exchanger 6, thereby forming a hot water cleaning and heat retaining pipeline 10 wherein hot water 9 in a bath tub 8 heat- exchanges the anti-freeze solution 3 in the heat exchanger 3 and is allowed to return to the bath tub 8. A three way valve V3 is installed between a filter 11 of a feed line 10a and the heat exchanger 6 where the three way valve V3 and the feed line 10a are connected with the bypass circuit 12.
