Gecko heater replacement
Gecko's in.therm and in.xm heaters run in any spa with a Gecko control pack. We replace the element or the complete assembly — Incoloy or Titanium — flat-rate and same-day.

The heater built into your Gecko pack
Gecko Alliance is one of the two big spa control-system makers, and its heaters are integrated into its control packs — the in.therm standalone heater, the heater inside the in.xm and in.ye systems, and the assemblies in older SSPA and MSPA Pro Pack controls. If your topside or pack reads Gecko or Aeware, the heater is one of these.
Mechanically it's a flow-through tube like any other: a heating element inside, with temperature and high-limit sensors on the tube reporting to the board. A Gecko heater typically fails when the element burns open (no heat, often no code), the element grounds out (trips the GFCI), or a sensor or flow fault keeps the board from letting it fire.
Because Gecko parts are common, we stock the typical in.therm and in.xm elements and assemblies and finish most Gecko heater jobs the same day across Palm Beach County.
The faults we see most
Open element — no heat
The element burns open and stops heating, frequently with no error code at all.
Grounded element — trips breaker
A cracked element leaks to ground and trips the GFCI the moment the heater fires.
Sensor / high-limit faults
HL or OH codes from a drifting sensor or a high-limit tripping on low flow.
Scale-clogged tube
Hard-water scale chokes flow and overheats the tube on neglected spas.
Which element belongs in your Gecko heater?
Gecko heaters run an Incoloy element as standard, with a Titanium option. Incoloy is fine for conventionally sanitized fresh water — but in Florida, where saltwater spas and aggressive chemistry are common, Incoloy corrodes and fails early.
If you run salt or your last element didn't last, we'll fit a Titanium element. It costs a little more upfront and pays for itself in lifespan. We show both prices and let you choose.
Element or complete assembly
We replace just the element when the tube is sound, or the complete heater when it isn't. Confirmed at your $69 diagnostic, credited to the repair.
What's your heater doing?
Answers before you call
Both. If the tube and housing are sound, we replace just the element from $189. If the tube is corroded or scaled through, a complete assembly is the lasting fix at $389 (Incoloy) or $469 (Titanium).
If your spa pack or topside reads Gecko or Aeware — in.xm, in.ye, in.therm or SSPA — the heater is one of theirs. Send us a photo of the equipment and we'll confirm before we come out.
Titanium for saltwater spas or anywhere chemistry runs hot — it lasts far longer in Florida water. Incoloy is fine for standard fresh-water sanitizing. We carry both.
Usually yes. Gecko parts are common, so we stock the typical in.therm and in.xm elements and assemblies and finish most jobs the same day across Palm Beach County.
We stock it — and we'll fix it today.
Flat-rate from $189 (element) or $389 (assembly). $69 diagnostic credited.
