Why waste your engine's heat? You've paid for it!

Even the smallest water-cooled marine engine discharges large amounts of ‘waste’ heat.  This rejected energy won’t help to propel your boat, but it’s ideal for heating up your domestic water supply, and far too useful to be dumped straight overboard. Why waste it? With a fully insulated C-Warm storage heater, you can heat a full tank of water (small or large) within half an hour, and keep it usefully warm for up to 18 hours after you’ve stopped using the engine.

Our FREE Selection Guide takes you step by step through the selection process, answering practical questions about installation, performance, safety and service life in plain non-technical language.

There are C-Warm sizes, shapes and styles to suit every vessel.   C-Warm storage heaters are designed for use with indirect-cooled engines, but can be used successfully with direct-cooled engines too. For best results with the latter, contact your supplier first for advice.
