What is a Marine Hydronic Heating System?
A hydronic heating system, similar to home heating systems, uses a hydronic heater to circulate hot water through pipes to radiant heating rafts or fan units, distributing heat throughout your boat, taking moisture out of the air.Benefits of Marine Hydronic Heating
- High Efficiency and Energy Savings: Compared to forced air systems, hydronic heaters use less fuel to deliver comfortable warmth, making them a more energy-efficient choice.
- Even Heat Distribution: Radiant heating rafts provide gentle and consistent warmth throughout your cabin, eliminating cold spots and drafts common with forced air systems.
- Reduced Moisture and Mold Growth: By maintaining a warm and dry environment, hydronic heat helps prevent the growth of mold and mildew, protecting your boat's interior.
