Compatible Gecko Control Systems
These heating assemblies are designed for use with the following Gecko spa pack systems:
- Gecko SSPA (S-Class) — the most common application
- Gecko Spa Builders Pack (SBSG)
- Gecko MSPA (M-Class) — select 3.0 kW universal models
- Gecko in.xe, in.ye, in.yt series (4.0 kW replacement)
Important: Before ordering, confirm your circuit board connection style. Older SSPA boards use soldered tab terminals, while newer boards use detached pigtail wire connectors. Ordering the wrong style is a common mistake — and we're here to help you avoid it.

Frequently Asked Questions
How do I know which Gecko S-Class heater I need?
Check the label or part number on your existing heater assembly if it's still visible. If you can't identify it, look at your circuit board: older boards have soldered tab connections; newer boards use pigtail wire connectors. You can also send us a photo along with your spa's make, model, and serial number and we'll confirm the correct part for you.
What's the difference between the 4.0 kW and 5.5 kW heater?
The wattage rating relates to the heating power of the element. Most SSPA systems use either a 4.0 kW or 5.5 kW heater depending on the model and configuration of your spa pack. Always replace your heater with the same wattage as the original to ensure proper performance.
Does this heater come with a pressure switch?
It depends on the model. Some assemblies include a pressure switch; others do not. Newer versions of the 4.0 kW and 5.5 kW pigtail-style heaters may come without the pressure switch pre-attached. Contact us and we'll let you know exactly what's included with the specific assembly you need.
What if I can't find my part number?
No problem. Send an email to fixmytub@gmail.com with photos of your existing heater and circuit board, along with your spa's make, model, and serial number (usually found on a plate on the outside base of the spa). Our team will identify the correct part for you.
Can I install this heater myself?
Many spa owners with basic mechanical skills replace heater assemblies themselves. That said, if you're not comfortable working with electrical components, we recommend having a qualified spa technician handle the installation.
Do you ship across Canada and the US?
Yes. Contact us for shipping details and availability on specific models.
