The DVAG17N is a 17,000 BTU direct-vent natural gas heater designed for bedrooms and living spaces. It heats up to about 570 square feet and uses a sealed burn system, which can improve indoor air quality by limiting combustion byproducts. This model’s direct-vent configuration reduces indoor venting requirements, and its cream finish complements many interior decors.

This unit is suitable for spaces like bedrooms or home offices where a compact, quick-heating option is beneficial.
Buying Guide: Key Purchase Considerations
- Space size and heating load: Choose BTU output that matches the space. Larger rooms need higher BTU units like the 80,000 BTU Big Maxx, while smaller rooms can be warmed effectively by 10,000 BTU or 17,000 BTU models.
- Ventilation and installation: Direct-vent models (Ashley DVAG17N) require venting to the outdoors, while ventless units (ProCom MN100TBA-B) have different safety considerations and indoor air quality implications. Consider whether you can accommodate vertical or horizontal venting for larger unit heaters.
- Fuel type and efficiency: All options here run on natural gas, with several models offering efficient operation and consistent performance in American homes. Review the energy factors and the potential for long-term savings on gas consumption.
- Installation location: Stationary unit heaters are ideal for garages, workshops, or basements, while portable heaters provide flexible warmth for temporary needs. Factor in space constraints, clearance requirements, and electrical supply when selecting a model.
- Safety features: Look for stable housings, proper clearance guidelines, flame monitoring, and shutoff mechanisms. Ventless models should include carbon monoxide considerations and room air exchange needs.
- Maintenance and access: Choose models with accessible thermostats and straightforward maintenance routines. Some units include easy-access panels or external gas connections for simplified servicing.
- Control and smart features: Some gas heaters offer basic thermostatic control, while others may have more advanced interfaces or compatibility with remote controls or Wi-Fi modules. Consider whether smart control features are important for your setup.
- Noise and aesthetics: If the heater is in living areas, consider noise levels and how the unit blends with décor. Direct-vent and ventless options come in different finishes to suit interior design.
