Hot Spring / Watkins Low-Flow Heater – 3.0 kW Double Barrel, Sensors & Pressure Switch
Replacement low-flow heater assembly made by HydroQuip, part number 26-C3072-3. Match the heater style (shape), wattage and switch/sensor type to the heater you are replacing.
What is a low-flow system? Older and some premium spas (early Artesian, Hot Spring/Watkins, many Jacuzzi, Sundance, Caldera and Dimension One models) heat with a small 24-hour circulation pump instead of a high-flow jet pump. Those spas need a low-flow heater — a standard 2″ flow-through heater will not see enough water flow to heat safely.

Low-flow spas heat with a small circulation pump running most of the day, and the heater is a small canister or tube (square back, trombone, double barrel, vertical) instead of a 15" long 2" flow-through tube. Send us a photo of your equipment and we will tell you.
