Enjoy year-round comfort aboard your boat, caravan, or motorhome with Action Outdoors’ Marine RV Heating systems — built to withstand New Zealand’s toughest weather conditions.

Why You Need a Dedicated RV or Marine Heating System

New Zealand’s climate is famously unpredictable — crisp winter mornings, cold coastal winds, and damp overnight conditions can make travel uncomfortable or even unsafe without adequate heating.

A properly installed LPG or space heater not only provides warmth but also:

• Prevents condensation and moisture buildup inside cabins and motorhomes.
• Protects electronics, upholstery, and fittings from damp-related damage.
• Improves comfort and sleep quality, especially during long trips.
• Extends your travel season, allowing safe, warm adventures all year.

For marine users, heating is essential to counter humidity and sea spray, ensuring dry cabins and reduced corrosion risk. In motorhomes and RVs, heating keeps your living space cozy without relying on camp power.

Choosing the Right Marine or RV Heating System

The best heating system depends on your vehicle size, insulation, and travel style. Consider these factors when selecting your heater:

1. Heating Capacity

• Small vans or cabins: Propex LPG Air Heater or Whale Space Heater.
• Medium to large RVs: Suburban LPG Air Heater.
• Compact layouts: Whale Underfloor Heater for discreet installation.

2. Energy Source

LPG (propane) is the most efficient and reliable heating source for off-grid travel. It’s readily available throughout New Zealand and provides consistent performance even in cold weather.

3. Noise Level

If you’re sleeping in close quarters, opt for Propex or Whale heaters, which are known for their quiet operation.

4. Installation Space

Choose an underfloor or compact heater if space is limited. Larger vehicles can accommodate ducted systems like the Suburban LPG Heater.
