Mr.Heater Heaters & Accessories MHVFDF20BFT Editorial Review
** Mr. Heater MHVFDF20BFT 20,000 BTU Vent Free Blue Flame Dual Fuel Heater** The Mr. Heater MHVFDF20BFT stands out as a robust option catering to those searching for a dual fuel heating solution suitable for cold spaces like cabins, additions, and sunrooms. With the capability to operate on both natural gas and propane, this unit has garnered a mix of commendations and critiques from users, particularly on its dual fuel functionality. On the positive side, customers have reported significant heating effectiveness, noting that it efficiently warms spaces up to 700 square feet. Many users appreciate the unit's efficiency, claiming it burns 99.99% clean, which contributes to its appeal as a reliable backup heating source, especially during power outages. The convenience of being able to switch between fuel types is highlighted, though users are cautioned that this requires professional intervention for setup. However, potential buyers should be aware that the heater is primarily designed for permanent installation and that transitioning between natural gas and propane is not as straightforward as one might hope. While it may seem appealing as a dual fuel appliance, the operational design leans towards fixed installation in one fuel type at a time, which has led to some dissatisfaction. Several users expressed disappointment, feeling that they could find better value in single-fuel models from Mr. Heater, should they know their fuel preference upfront. Installation appears to be a recurring theme in the reviews, with numerous customers mentioning complications related to setup. Some users encountered issues such as unclear instructions or missing components. While the heater does feature the option to add a blower fan, details regarding its installation remain vague, leading to speculation on the ease of such an upgrade. Despite these Considerations, the overall reception of the Mr. Heater MHVFDF20BFT remains largely positive due to its heating capabilities and potential as a reliable emergency solution, while also serving as a reminder to Prospective customers to clearly understand their fuel needs and installation requirements before purchase. **
