Power Output
Works amazing, heats up a 24x25 garage in just 2-3 minutes even in -10/-15 degree weather.
Temperature Control
The thermostat operates just like an indoor home thermostat, adding to the ease of use.

The Modine Hot Dawg Gas Fired Unit Heater (Propane 75000 BTU) is a robust option for heating indoor areas like garages. With a power output of 75,000 BTU, it is capable of warming large spaces efficiently. The unit is designed in a cabinet form factor and mounts using a ceiling bracket, which can save floor space and position the heat source optimally for better circulation.

However, it is relatively heavy at 181 pounds, which might make installation challenging without assistance. It's specifically intended for indoor use, making it a good fit for enclosed areas like garages or workshops. The heater operates on propane and boasts an 80% efficiency rating, indicating that it converts most of its fuel into useful heat. This efficiency is decent but not the highest available on the market.

Temperature control options are not explicitly mentioned, which could be a drawback for those needing precise heating settings. Safety-wise, being power vented adds a layer of protection against gas buildup, but there are no specific safety features highlighted in the description. Potential buyers should consider the installation requirements and possible limitations in temperature control.

Temperature Control
The heater requires a special 24-volt thermostat, which is not easy to find and should be noted by the manufacturer.

The RHT-75-30-P Two-Stage Propane Gas Radiant Tube Heater is geared towards commercial, not residential, settings. With a substantial power output of 75,000 BTU, it’s well-suited for large spaces where significant heat distribution is required. The heater’s 30-foot length allows it to cover a wide area, making it an effective solution for warehouses or large outdoor areas.

Its construction features black-coated aluminized steel emitter tubes and mirror-finish aluminum reflectors, which are designed to enhance the heat radiation while potentially offering durability. However, the product’s specification that it is not approved for residential use limits its audience to primarily commercial users. In terms of mounting, it is designed for floor mount installation, potentially requiring professional setup to ensure safe and effective operation.

The heater operates on propane and has two speeds, allowing some flexibility in temperature control. Potential buyers should note the emphasis on commercial use and ensure the heater meets safety standards for their specific application. Its robust construction and high power output are certainly strengths.

Buying Guide for the Best Tube Heaters

Tube heaters are a great solution for providing consistent and efficient heating in various spaces, such as greenhouses, garages, and workshops. When choosing a tube heater, it's important to consider several key specifications to ensure you select the best fit for your needs. Understanding these specifications will help you make an informed decision and ensure that the heater you choose will effectively meet your heating requirements.
Power OutputPower output, measured in watts, indicates the amount of heat the tube heater can produce. This is important because it determines how effectively the heater can warm up your space. Tube heaters typically range from low power outputs (around 60-120 watts) to higher outputs (up to 240 watts or more). If you have a small area or need gentle heating, a lower wattage heater may suffice. For larger spaces or areas that require more intense heating, opt for a higher wattage model.
LengthThe length of the tube heater affects its coverage area. Longer heaters can distribute heat more evenly across a larger space, while shorter heaters are better suited for smaller areas. Tube heaters can range from around 1 foot to several feet in length. Consider the size of the area you need to heat and choose a length that will provide adequate coverage without leaving cold spots.
Mounting OptionsMounting options refer to how the tube heater can be installed. Common options include wall-mounted, floor-mounted, or ceiling-mounted heaters. This is important because it affects the heater's placement and how it integrates into your space. Wall-mounted heaters are great for saving floor space, while floor-mounted heaters can be more portable. Ceiling-mounted heaters are ideal for areas where floor and wall space is limited. Choose a mounting option that best fits your space and installation preferences.
Safety FeaturesSafety features are crucial for ensuring the safe operation of your tube heater. These can include overheat protection, thermal cut-off, and waterproofing. Overheat protection prevents the heater from getting too hot, while thermal cut-off shuts the heater off if it reaches a dangerous temperature. Waterproofing is important for heaters used in damp environments like greenhouses. Look for heaters with robust safety features to ensure peace of mind and safe usage.
Energy EfficiencyEnergy efficiency indicates how effectively the heater converts electricity into heat. This is important for reducing energy consumption and lowering your utility bills. Tube heaters with higher energy efficiency ratings will use less electricity to produce the same amount of heat compared to less efficient models. Look for heaters with energy-saving features or certifications to ensure you are getting a cost-effective and environmentally friendly option.
Temperature ControlTemperature control allows you to adjust the heat output of the tube heater to suit your needs. This can be done through built-in thermostats or adjustable settings. Having control over the temperature is important for maintaining a comfortable environment and preventing overheating. If you need precise control over the heating levels, look for heaters with adjustable thermostats or multiple heat settings.
