Mr. Heater F260550 Big Maxx MHU50NG Natural Gas Unit Heater
The Mr. Heater Big Maxx MHU50NG is a natural gas unit heater rated at 50,000 BTU per hour designed for larger spaces such as garages and workshops. Its powered exhaust allows for either vertical or horizontal venting, giving flexibility in installation when roof or wall venting is required. The unit offers convenient outside access to the thermostat, A/C terminals, and gas connection for serviceability. It’s specified to heat up to 1,250 sq. ft. which positions it for medium-to-large single-zone spaces. The design and features emphasize robustness for fixed natural gas installations; thermostat, hose, and regulator are not included and proper clearances and venting category must be followed during installation.
Broan-NuTone 157 Low-Profile Fan-Forced Ceiling Heater
The Broan-NuTone 157 is a low-profile ceiling-mounted fan-forced heater intended as a supplemental heating source for bathrooms, kitchens, and small rooms. Operating at 1250W and 120VAC, it uses an enclosed metal sheath element for reliable heat and includes a durable satin aluminum grille to match decor. Its compact housing is ideal where a discreet ceiling-mounted solution is preferred. The unit is best suited for localized warming rather than whole-garage heating and is commonly paired with bathroom ventilation or light units in retrofit projects.

The Comfort Zone 5,000-Watt ceiling heater is a hard-wired fan-forced unit intended for garages, warehouses, and shops where floor space matters. Built from heavy-gauge steel, it offers durable construction for tougher environments. The heater includes louvers and an adjustable mounting angle for directed airflow and features overheat protection. Its three heat settings help tailor output to usage, while the ceiling-mount format preserves floor space. This model is aimed at commercial-style applications or large residential garages with sufficient electrical capacity for hard-wiring.
Dr. Infrared Heater 10,260 BTU Infrared Heater
The Dr. Infrared 10,260 BTU model uses a carbon infrared element delivering 3000W of instant heat suitable for indoor and outdoor zones. Rated IP55 for weather resistance, it supports ceiling or wall mounting and includes a remote for control. Infrared heating warms objects and people directly rather than just air, which can be effective for patios, partially enclosed garages, and focused work areas. The heater operates on 220–240V and includes mounting hardware for ceiling installation, making it versatile for different settings.
TEMPWARE Electric Garage Heater, 7500-Watt Digital Ceiling Heater
The TEMPWARE 7,500-Watt ceiling-mounted shop heater provides high-output electric heating with adjustable louvers and an adjustable mounting angle. It offers multi-stage power ranges and a built-in thermostat with ECO mode plus a programmable auto-off timer. Safety features include overheat protection. Rated to cover up to approximately 1,250 square feet at peak output, this unit is targeted at heavy-duty garage and workshop use where a powerful, digitally controlled fan-forced ceiling unit is desired and where 240V hard-wiring is available.

Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes
Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors. - Negotiate Smartly
Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Heating Capacity And Coverage
- BTU And Watt Ratings: For gas unit heaters, BTU ratings indicate output (e.g., 50,000–80,000 BTU for larger spaces). For electric and infrared units, watts or BTU-equivalent describe capacity (e.g., 3,000W ≈ 10,000 BTU).
- Room Size: Match capacity to square footage and insulation level. Heavier-duty garage applications require higher BTU/wattage than a small bathroom or RV rooftop.
Fuel Type And Power Supply
- Natural Gas/Propane: Gas unit heaters (like Mr. Heater models) provide high output and lower operating cost where gas is available. They require venting and combustible safety clearances and professional gas and vent installation.
- Electric: Electric fan-forced ceiling heaters are easier to install where 120V/240V electrical supply exists. They are often safer for enclosed spaces but may incur higher operating costs at high outputs.
- Infrared: Infrared heaters warm objects directly and are efficient for partially open spaces like patios or spot heating in a garage.
Mounting, Venting, And Installation
- Ceiling vs. Rooftop vs. Wall: Verify manufacturer mount options. Many electric and infrared units offer ceiling and wall mounts; rooftop units for RVs are roof-specific.
- Venting Needs: Gas heaters require correct venting (vertical or horizontal depending on category) and minimum clearances. Check vent category and installation instructions.
- Electrical Requirements: Hard-wired 240V units need qualified electrician installation. Confirm circuit size and breaker requirements before purchase.
Controls, Thermostat, And Features
- Built-In Thermostat: Units with integrated thermostats and programmable ECO modes provide better temperature control and energy savings.
- Remote/Smart Control: Remote or WiFi-controlled units add convenience for RV or patio applications and allow remote operation in some electric models.
- Louvers/Adjustable Angle: Directional louvers or adjustable mounting angle help deliver heat where needed and improve distribution for larger areas.
Durability And Safety
- Construction: Heavy-gauge steel housings suit workshops and harsh conditions; aluminum grilles suit indoor decor-sensitive installs.
- Overheat Protection And Listings: Look for built-in overheat shutoff, ETL or similar safety listings, and IP ratings if outdoor exposure is possible.
- Clearances: Check manufacturer-specified clearance from floors, ceilings, and combustibles to maintain safe operation.
Space-Specific Recommendations
- Garage/Workshop: Choose high-output gas or high-watt electric ceiling heaters with adjustable louvers for broad coverage and durable construction.
- Bathroom/Kitchen: Opt for low-profile fan-forced ceiling units or combination heater/ventilation fixtures designed for smaller, enclosed rooms.
- RV/Rooftop: Select rooftop units specifically rated for mobile use with combined cooling and heating if year-round comfort is required; ensure electrical compatibility and roof cutout sizing.
- Patio/Outdoor: Use weatherproof infrared models rated for outdoor use to provide directed heat without overly heating ambient air.
Energy Use And Operating Cost
- Efficiency Metrics: Compare wattage and BTU outputs relative to the area being heated; higher efficiency models and thermostatic control reduce runtime.
- Fuel Cost Differences: Natural gas can be less expensive per BTU in some regions, while electricity provides cleaner installation but potentially higher running costs at sustained high loads.
- Smart Features: ECO modes and timers reduce unnecessary runtime and can yield measurable savings in garages and shops.
Installation And Maintenance
- Professional Installation: Gas and high-voltage electric units typically require licensed installers. Verify local codes and venting requirements.
- Access For Service: Choose units with accessible thermostat and electrical terminals if future maintenance is a concern.
- Filter And Cleaning: Fan-forced units may collect dust; schedule periodic cleaning for fans and louvers to maintain airflow efficiency.
Comparison Summary
- High Output & Whole-Bay Heating: Natural gas unit heaters like Mr. Heater Big Maxx models deliver the highest continuous output for large garages and workshops but need venting and gas service.
- Compact Room Heat: Low-profile units such as Broan-NuTone suit bathrooms and small rooms where discreet ceiling mounting and modest wattage are desired.
- Spot/Outdoor Heat: Infrared models such as Dr. Infrared provide direct radiant heat ideal for patios or targeted areas inside a garage.
- Smart Digital Control: Models with digital thermostats, ECO modes, and timers (e.g., TEMPWARE) suit users who want programmable, more efficient electric heating for workshops and garages.
