Spa Sizing

Determine your spa capacity in gallons (surface area x average depth x 7 ½)

The reference table lists the time required in minutes to raise the temperature of the spa/hot tub by 30ºF

This guide can be adjusted for other temperature rises. For example, if you desire a 15ºF increase in temperature, 

simply divide the time for 30ºF rise by the ratio of 30/15 = 2.

Spa sizing is based on an insulated and covered spa. Always cover your spa or hot tub when not in use to 

minimize the heat loss and evaporation.

Increase the temperature of a 300 gallon spa to go from 70ºF to 100ºF in 120 minutes.
