Water Pro Gecko YE-5 Lo-Flo Spa Pack – 5.5 kW SlipStream Heater, in.k200 Topside (CS6P52Y-US)
Complete Water Pro retrofit control system by HydroQuip with a low-flow canister heater — the drop-in way to modernize an older low-flow spa (early Artesian, Hot Spring, Jacuzzi, Sundance, Caldera and similar). Part number ATEGRLL-95W6H40.
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.

✅ Not Sure It Fits? Verify Before Ordering
Hot tub part compatibility can vary by spa brand, model, year, serial number, control system, and part revision.
To help us identify the correct replacement part, please send clear photos of:
- Your existing part label or sticker
- Your spa serial number sticker
- The equipment area or installation location (if accessible)
EZ Hot Tub Parts can help confirm fitment before you order and help reduce costly returns.
Compare the part number ATEGRLL-95W6H40 with the label on your old part, and match the style, wattage and connections. Not sure? Send photos through the fit-check form above and we will confirm before you order.
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.
