7. Heating Times for C-Warm Electric
Immersion Heaters
Heating times in minutes to heat a full tank
of water from 10 deg C to 55 deg C. A usable amount of hot
water will accumulate by convection in the top of the heater
in less time than that shown.

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.
