Torrid Marine Water Heaters / RMC, Inc.

Glass-lined tanks, similar to those used in millions of homes, are designed to last longer than their guarantee period. Additional protection against corrosion is provided by installing a magnesium anode with a deliberate size and location that we have proven to be superior in prolonging the life of our water heaters. This allows us to offer a 5-year guarantee against tank failure.
We use a high-quality heat exchanger made of copper with a silicon bronze casting.
Most manufacturers use copper heating elements, while we have determined that an Incoloy sheathed heating element is superior. A copper sheathed element will burn out in two or three seconds if not immersed in water, while ours will burn in air and cannot be damaged by energizing the electrical circuit when the tank is empty. We also guarantee the element for five years.
The thermostat is manufactured specifically for our marine water heaters. The energy cutoff is set at 200° F so that normal fluctuations of engine water temperatures will not cause nuisance tripping of the electrical circuit.
Our side connect hot water outlet is fitted with an internal tube which takes water from the top of the tank head. This eliminates air trapped in the top of the tank when filled with water, which is a common complaint with other side-connected designs. Keep in mind that other top-connect tanks are bulkier, and won’t fit in many locations where there is a height limitation!
Not only do we use a high density fiberglass insulation, but we also pack it in more tightly than necessary. This extra measure ensures a longer period of time for stored hot water.
