For owners of Dometic-equipped RVs, a modern capacitive touch thermostat can provide more intuitive control and reliable temperature management with heating appliances. Confirm electrical pinout, control signal compatibility, and mounting dimensions before replacing OEM thermostats to avoid control issues.

Buying Guide: Choosing An RV Propane Heater With Thermostat

This buying guide summarizes the key factors to evaluate when selecting a propane heater and thermostat combination for RV use. Consider safety, heat output, installation, control features, and system compatibility.

1. Heat Output And RV Size

• BTU Rating: Match the heater’s BTU output to your RV’s living volume. Small heaters (around 10,000 BTU) suit compact RVs, while larger units (20,000–30,000 BTU) fit larger motorhomes or towable rigs with better ventilation.
• Coverage Claims: Manufacturer square-foot claims assume typical ceiling heights; adjust for high ceilings or poor insulation.

2. Thermostat Control Types

• Built-In Thermostat: Integrated units (ProCom, Mr. Heater) provide on-device temperature control and cycling, simplifying setup.
• Wall Thermostats: OEM or replacement wall stats (Suburban, FORZEEY) can control compatible furnaces or centralized heaters and offer convenient setpoint control from living areas.
• Precision & Interface: Capacitive touch and digital displays often improve setpoint accuracy and user experience over basic mechanical dials.

3. Safety Features

• Oxygen Depletion Sensor (ODS): Automatically shuts off propane flow if oxygen levels drop; vital for enclosed spaces.
• Automatic Shutoff & Overheat Protection: Look for flame fault protection and thermal cutoffs to reduce risk.
• Ventless vs. Venting: Ventless heaters increase indoor combustion products; ensure ODS and local approvals. Venting provides exhaust management but may not be available for all RV installs.

4. Fuel Supply And Consumption

• Propane Flow Rate: Verify that your RV’s regulator and tank capacity support continuous consumption at the heater’s maximum BTU.
• Multiple Appliances: Consider concurrent appliance use (stove, water heater) when sizing tanks and regulators.

5. Installation And Compatibility

• Mounting Options: Wall-mounted units require clearances and secure attachment; portable or floor-mount units need stable placement.
• Electrical Requirements: Thermostats and electronic ignitions often need 12V DC power; confirm your RV wiring and fuse capacity.
• Thermostat Wiring & Signals: Replacement thermostats must match control signal types (on/off, modulating) used by your furnace or heater controller.

6. Comfort And Efficiency

• Thermostat Accuracy: A more accurate thermostat reduces short cycling and improves fuel economy.
• Heat Distribution: Blue flame units and infrared units provide different heat transfer styles—blue flame for convective heating, infrared for radiant warmth.

7. Regulatory And RV Manufacturer Guidance

• Local Codes: Check local regulations about ventless appliance usage in recreational vehicles.
• RV Manufacturer Recommendations: Follow the RV maker’s installation instructions and warranty requirements when altering heating systems or replacing thermostats.

8. Comparison Perspectives

• Small RV / Camper Van: Favor compact, lower-BTU infrared or 10k BTU blue flame units with accurate built-in thermostats.
• Large Motorhome / Park Model: Consider 20k–30k BTU wall or vented options with ODS and thermostat integration for steady climate control.
• Thermostat Replacement: Choose direct-fit replacements for OEM systems (check Dometic compatibility) or universal stats compatible with your furnace controller type.

When evaluating products, cross-reference manufacturer installation guides, safety certifications, and your RV’s appliance configuration. Prioritize units with documented safety features and proven compatibility with your RV’s fuel and electrical systems.
