Hot Tub Pumps, Heaters and Controls

Though not as flashy and visible as the shell, cabinetry, seating and jets, the pumps, heaters and controls are essential components of your home spa. Select a pump, or combination of pumps, that has the capacity and water-moving power to accommodate the size of your spa as well as the type of jets. High action jets typically command a more sturdy pump, while standard jets can on the whole get by with a smaller pump. In most cases, though, a multi-pump set-up is preferable to a single pump system for the most effective and functional water movement.

The heater is an vital component that should be sized correctly for the water capacity of your spa. If your heater is too small or underpowered, you will have constant struggles heating your spa water and the heater will be required to work extra hard. A high quality heater, paired with good insulation, will go a long way toward efficiently heating the water in your spa and keeping the temperature where you want it.

Traditionally, hot tubs and home spas used pneumatic controls to run pumps, heaters and the like. Electronic controls have gained some in popularity, but they have a questionable record of reliability and until the last few years have not been a popular choice. Technology improvements have made them much improved, though, so don't automatically dismiss electronic controls when shopping for your home spa.
