	Dear All We have 2 hot water calorifiers in parallel configuration to supply hot water for a 5-star hotel. Primary source is Steam. We want to change sequence each other every 3 month (One on Operation and other one stand by). What is the best way to shout down and put on operation other one with less Energy loss, no guest complain and best life of equipment. Thanks Ediri

	Best way is to bring the standby online and up to operating temperature before switching the other unit to standby configuration. Hotels with only one star may do it another way.

	What's this "calorifier"? Anything like a "heater"? (I can just imagine some pretentious twit saying "I calorified my teapot of water to 100°C.")

	Reply #1 is good. If you are interested in long term energy savings, repiping (if necessary) so that the hot water can pass through both calorifiers in series, adding both A to B as well as B to A. Then when switching from A to B and Reply #1 action is taken, and both are in operation, the feed can be switched through A to B, shut off heat to A until A is cold, then switch cold feed to B. If a simple manifold system with ON/OFF valves is used, you can isolate each side for repairs, etc, as well as recover the residue heat in the shut down side without interrupting the water flow. Whether this is economically feasible depends on specific factors you have not provided. The system may be already in the appropriate conformation.
