Garbage Disposal Installation
If everything in a house consumes hot water simultaneously, then it theoretically gives the GPM necessary for the household. However, it is unlikely that all of the hot water appliances, including faucets, showers tubs and washers, would be used simultaneously. In practical terms, a 5 GPM unit is enough for a small house; 7-10 GPM for a large home would suffice. Individuals who require greater heating capacity may consider multiple or twin heaters.
