C-Warm immersion heaters have low power ratings to match the electrical supplies provided by most marinas. Immersion heaters of higher power can be supplied to special order.

Low voltage d.c. immersion heaters would take high currents and are impractical for most users. (Example: a 0.75kW 24 d.c. immersion heater would take a continuous current of 30 amps) Low voltage immersion heaters are not offered in the C-Warm range.
