Rinnai EX08DTP Direct Vent Wall Furnace
The Rinnai EX08DTP is a compact direct vent heater designed for indoor use. It offers 8,000 BTU and a modulating gas valve for responsive heating. Its electronic spark ignition and 7-stage modulation help match heat to demand, while a cool-to-the-touch cabinet and child lock emphasize safety in homes with children. A smart thermostat and digital controls support a temperature range of 60–80°F for stable comfort. This unit is best for small rooms or bedrooms where space efficiency and quick warmth matter most. Limitations include a smaller output that may require pairing with supplemental heat in very cold areas.
Rinnai EX22DTP Direct Vent Wall Furnace
The 20,700 BTU Rinnai EX22DTP provides stronger heating for medium-sized rooms. It uses advanced modulating technology to maintain even temperatures and reduce cold spots. Like the smaller model, it includes a cool-to-the-touch cabinet and self-diagnostics for safe operation, making it a solid choice for families seeking reliable warmth with minimal maintenance. It is best for living rooms or large bedrooms, but may be overkill for very small spaces where the EX08DTP suffices. Caution: ensure proper clearances for wall installation and venting in tight spaces.
Comfort Glow 11,000 BTU Direct Vent Natural Gas Wall Heater
The Comfort Glow 11,000 BTU model heats up to 350 sq. ft. It features a sealed burn system with electronic ignition and a safety pilot with a regulator to stop gas flow if the pilot goes out. This unit emphasizes safety and space-saving design, mounting easily on walls with compact dimensions. It’s best for small-to-medium rooms where a simple, reliable heat source is preferred. A potential limitation is that its output is modest relative to larger rooms or open floor plans.
Comfort Glow 17,000 BTU Direct Vent Natural Gas Wall Heater
This 17,000 BTU model covers larger spaces efficiently, heating up to about 500 sq. ft. It uses a sealed burn system with electronic ignition and a safety pilot, plus a built-in regulator. Its wall-mounted design preserves floor space, making it a good pick for medium-to-large rooms where centralized heat is beneficial. Consider this if you need stronger warmth without looking at gas-fueled furnaces. A notable consideration is ensuring your room size aligns with the heater’s higher output to avoid overshooting comfort.
Rinnai EX38DTWP Direct Vent Wall Furnace
The 36,500 BTU Rinnai EX38DTWP is designed for larger spaces and open floor plans. It delivers consistent heat with advanced modulation and a cool-to-the-touch exterior for safer indoor use around families. Its size and output make it a strong option for zones where a single unit must cover multiple rooms or a large living area. Best for larger living spaces, but installation requirements are more complex, so confirm venting and clearances beforehand. Caution: higher output units require appropriate electrical and venting infrastructure.
Buying Guide
- What room size can this heater effectively cover? Match BTU output to square footage and ceiling height for best comfort and efficiency.
- Direct vent vs. vent-free: Direct vent systems pull combustion air from outside, improving indoor air quality and safety. Consider if outside venting is feasible in your space.
- Safety features: Look for cool-to-the-touch cabinets, child locks, self-diagnostics, and automatic shutoff to reduce risk in homes with kids or pets.
- Modulation and thermostat control: Heaters with multi-stage gas valves and programmable thermostats maintain stable temperatures and reduce energy use.
- Installation and maintenance: Confirm clearance requirements, electrical needs, and access for routine service. Some units require professional installation.
- Fuel type and efficiency: Propane direct vent units offer clean burning and efficient operation; consider availability and cost of propane in your area.
Frequently Asked Questions
- Are direct vent propane heaters safe for bedrooms? Yes, when installed with proper clearances and venting, direct vent heaters provide safe indoor heating with outside air for combustion and cool-touch exteriors.
- What size heater do I need for a living room? Estimate by square footage. For example, 20,000 BTU covers larger living areas, while 8,000–11,000 BTU units fit smaller rooms. Modulating models help adapt to temperature changes.
- Do these heaters require outside venting? Yes, direct vent systems pull combustion air from outside and vent exhaust outside, reducing indoor moisture and fumes.
- Can I install these myself? Some models allow DIY installation if local codes permit; many installations require a licensed professional to ensure venting, clearances, and gas connections are correct.
- Will a blower increase heating costs? A blower can slightly increase energy use, but it typically improves perceived warmth and reduces overall time-to-comfort, which can offset cost in cold rooms.
- What maintenance is needed? Regular inspection of venting, gas connections, and safety features is recommended. Self-diagnostic electronics assist with troubleshooting.
