A small percent of tank volume is subtracted from EF to calculate efficiency. As a result, smaller tanks can be more efficient, but with the additional insulation added to tanks manufactured after April 2015, the efficiency is same for 30-40-50 gallon heaters. If you need larger heater, install two water heaters Resource: Two water heaters |
