At Easy Spa Parts we carry every Dimension One Spas heater still available. Starting in the 1980’s, D1 heaters often used a replaceable heating element similar to a water heater design but about 12” long. With the advent of the Crystal Pure Ozone System, Dimension One introduced a large heating coil that efficiently warmed the water at low wattage. By 1997 many Dimension One hot tub heaters began using a Laing heater. This 01781-27 low flow heater utilizes a small circulation pump to silently move water through the heater tube. The Dimension One @Home series currently uses the traditional 01562-08 2” flow through heater which requires the main jet pump, operating low speed, to heat the spa water.

If your D1 hot tub heater is not warming the water your first thought might be to buy a new heater. Think again. Better yet, call the expert technicians at Easy Spa Parts for help diagnosing your spa. Every UL certified hot tub requires a 01710-131 flow switch or 01515-04 pressure switch to insure there is adequate water flow through the heater, before allowing the water to warm. All other facets of the D-1 hot tub heater system could be operating correctly but if the flow switch is defective you’ll see the typical “Low Flow” error indicated on the main control panel. Watch our informative low flow error video on troubleshooting for more information.

If your D-1 heater requires a Laing 01512-320E low flow pump, a defective or air locked unit can also cause a low flow error. Again, watch our low flow video or call us for troubleshooting help here too. If all flow systems appear to be operating properly, you might need to use a small compressor to clear the heater / ozone lines to improve flow. Follow the steps in this instruction sheet to see if it helps.

Some D-1 spas with relatively new 01782-27 or 01781-27NS heaters may have tripped the TCO safety switch. Call us for an instruction sheet showing this procedure. All the steps above, and others, are offered so you understand that a Dimension One Spa that’s not heating does not necessarily mean you need to buy a new heater.
