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.
