GAS WATER HEATER SIZING GUIDE

Use the following information as a guide to approximate the correct size water heater for the residence:

•30 gallon size (21 gallon draw) for one bath residence.

•40 gallon size (28 gallon draw) for two bath residence -or one bath with an automatic clothes washer.

•50 gallon size (35 gallon draw) for three bath residence - or two baths with an automatic clothes washer.

•When a whirlpool tub is part of the home equipment, it is suggested that the water heater storage tank capacity be selected based on the needs of the whirlpool tub. This method of tank sizing, will in most cases, cancel all statements above concerning tank sizing.

•High flow or multiple shower head installations must be sized for at least a 20 minute draw.

*A thermostatic mixing valve set for a maximum temperature of 120° F is recommended to be installed to prevent a scalding hazard.

**Based on tub water temperature of 105º

Note: Because the desired fill time is normally 10 minutes, recovery capacity is not used for this calculation. All water used is supplied by storage.

NOTE: The draw efficiency of a gas or electric water heater storage tank is considered to be 70%.
