circuiti dell'acqua calda Explanation: vedi www.iir.it/newslett/prof_7_4.htm "Per contro, tutti i 26 campioni prelevati dal circuito dell'acqua calda, realizzato con tubi di polietilene" |

cicuiti chiusi di acqua calda Explanation: concordo che sono tubazioni, ma per loop si intende spesso un circuito che permette un ricircolo, cioè quello che si definisce un "circuito chiuso", come molti circuiti di raffreddamento o di riscaldamento. ------- Hospitals, hotels, and other large buildings have used hot water recirculating loops for years. Some of these loops use electrical recirculating pumps while others use gravity. Based upon the fact that your water heater is in the basement of your home, Mother Nature is going to do the work for free! Gravity hot water loops work because the heated water, which is lighter, rises through the loop. As the water cools at the top of the loop, it falls and is thermo-syphoned back into the hot water heater. The water enters the bottom of the heater at the drain valve inlet. This flow of water is slow but constant. For a gravity recirculating loop to work properly, the water heater must be located at the bottom of the loop. Ranch houses and two story houses with basements are perfect candidates. Houses built on slabs or that have hot water lines below the water heater must use a simple in-line recirculating pump. All you need to complete your loop is a return water line from the far end of your hot water line. Locate the end of your existing hot water line. Cut into the pipe at this location. Install a tee fitting. One part of the tee will allow you to reconnect to the hot water line. The other portion of the tee fitting will be the start of the return loop back to the water heater. |
