Coates 6ILS In-Line Electric Spa Heater, 1 Phase 240 V 6 kW In stock$49931
Quick overview
- Compact in-line design Plumbs directly into the circulation line rather than sitting as a separate appliance.
- Stainless steel tank The heater body is stainless, built for constant contact with treated water.
- Replaceable titanium elements Elements are titanium and are serviceable, so element failure does not mean a new heater.
- For spas and hot tubs under 400 gallons Intended for spas and hot tubs with a forced water circulation system holding less than 400 gallons.
- Single phase 240 V Rated 6 kW at 240 V, one phase, drawing 23 A, so size the circuit and breaker accordingly.
- Rating varies in the source This unit is also listed as 5.5 kW at 230 V, which reflects the same heater rated at a different supply voltage.

Product details
The Coates 6ILS is an in-line electric heater for spas and hot tubs, rated 6 kW on a single phase 240 V supply with a 23 amp draw. It plumbs into the circulation line rather than standing as a separate piece of equipment.
How it is built
The tank is stainless steel and the heating elements are titanium. Both choices are about living in treated water year after year. The elements are replaceable, which matters over the life of the heater: when an element eventually fails, it is a serviceable repair rather than a reason to buy a new unit.
What it is sized for
Coates intends this heater for spas and hot tubs that have a forced water circulation system and hold less than 400 gallons. It is a spa heater, not a swimming pool heater, and the compact in-line format reflects that.
Electrical and rating
Plan the installation around single phase 240 V and a 23 amp draw, and have the circuit and breaker confirmed by a licensed electrician. Note that this heater appears in the source under two ratings, 6 kW at 240 V and 5.5 kW at 230 V. Electric heater output moves with supply voltage, so those are two ways of describing the same unit.
