Mr. Heater F299730 Review: Heats Up to 30,000 BTU/hr for 750 Square Feet

F299730 Overview

Mr. Heater F299730 Propane Heater heats with 30,000 BTU/hr for you if you need a wall-mounted propane heater for a 1,000-square-foot space.

If your space needs wall mounting and no outdoor venting, the 30,000 BTU/hr rating changes which heaters belong on your shortlist.

Mr. Heater F299730 matches that scenario with electronic ignition, a built-in adjustable thermostat, and propane fuel. Its 1,000 square feet of maximum heating area is the other figure that matters when you are planning for a larger indoor space.

The Short Answer on the F299730

Best for: you need a wall-mounted propane heater for a 1,000-square-foot space and want electronic ignition with a built-in thermostat.

Choose the F299730 if you want 30,000 BTU/hr of heat and no outdoor venting requirement, at around $265.39.

• Pro: The 30,000 BTU/hr output suits a cabin during a multi-day outage, and the unit is rated for 1,000 square feet of coverage.
• Pro: Battery-operated electronic ignition means no electricity is required for startup, and the AAA battery is included.
• Pro: The built-in adjustable thermostat gives you a setpoint to work with instead of fixed full-output operation.
• Con: The 750 sq ft heating coverage is narrower than the 1,000-square-foot maximum heating area, so the smaller figure may matter if you want a tighter room-size match.
• Con: This wall-mount cabinet format rules out buyers who need a portable propane heater for moving between rooms or sites.

Don’t buy this if: you need a single unit for a big barn or open workshop that calls for 40,000 BTU/h or more.

Price assessment: Around $265.39 is fair for a 30,000 BTU/hr wall-mounted propane heater with electronic ignition and thermostat control.

Full Specifications for This Propane Heater

Heat output is the deciding spec that separates this model most, and it measures how much heat the heater can release each hour.

Before You Buy: Propane Heater Checklist

The first thing to check is whether you need wall mounting and whether your space matches the 1,000-square-foot maximum heating area. If either point is wrong, you may end up with a return or a heater that is too small for the room.

• ☐ Confirm wall-mount placement — Mounting Type: Wall Mount. If you need a freestanding heater, this one will not fit that setup and you will need a different model.
• ☐ Check your room size — Maximum Heating Area: 1,000 square feet. If your space is larger, you may have to buy a second heater or live with uneven warmth.
• ☐ Measure the area you want heated — Heating Coverage: 750 sq ft. If your room falls outside that coverage, the heater may leave cold spots and force a re-buy.
• ☐ Confirm you have propane fuel available — Fuel Type: Propane. If your site uses another fuel, this heater will not run there and the purchase will not solve the heating problem.
• ☐ Check whether you need electricity — Power Source: No electricity required. If you want a heater for outages or a spot with no outlet, this is a fit; if you expected corded power, you may choose the wrong unit.
• ☐ Budget for indoor safety requirements — Oxygen Depletion Sensor: Yes. If you skip this check, you risk choosing a heater that does not match your indoor safety needs and may face carbon monoxide buildup concerns in the wrong setup.

If you need a plug-in heater, or your room is larger than 1,000 square feet, do not buy this one.

What These Specifications Let You Do

What 30,000 BTU/hr Heat Output Can Cover

F299730 gives you 30,000 BTU/hr, which is enough output for a cabin during a multi-day outage or a room that needs steady heat while the power is out. That figure also puts it in the range where a single unit can handle the easier end of a larger garage job, so you do not need to treat 750 square feet as an automatic limit.

The same number is not enough for a big barn or open workshop space that needs 40,000 to 60,000 BTU/h. If your space is closer to 1,000 square feet, you should still check the room layout and insulation, because the stated heating area is a ceiling for intended use, not a promise about every floor plan.

What 1,000 Square Feet Indoor Coverage Means

F299730 is listed for 1,000 square feet, so it fits a larger garage or an open indoor area better than a small spare room. That coverage figure is the one that matters if you want one heater to carry a whole work space instead of relying on a second unit.

The 750 square feet figure tells a more cautious story for tighter rooms with poorer heat retention. If your garage is near that size, the heater still has room to work, but the real question is whether the space is open, insulated, or broken up by doors and partitions.

Why No-Vent Operation Matters Indoors

F299730 is a no-vent propane heater, so you are buying a room-heating setup that does not need outdoor venting. That matters for indoor spaces where a vented heater would add another constraint to the purchase, especially if you are trying to heat a living room, garage, or greenhouse with a wall-mounted unit.

The no-vent design also means you need to think about the trade-off that comes with vent-free heating: moisture and condensation are part of the category, and carbon monoxide risk is the failure mode buyers watch most closely. This model states an oxygen depletion sensor and electronic ignition, so the listing gives you two safety-related features, but it still belongs in the vent-free group that buyers judge by how carefully they match the heater to the space.

Which Jobs the F299730 Handles, Worked Out From Its Specs

The F299730 against the jobs buyers ask about, worked out from its listed heat output and a typical need for each job.

The F299730 Against Similar Propane Heaters

F299730 gives you 30,000 BTU/hr and a 1,000-square-foot maximum heating area, so it carries more room-heating headroom than the smaller vent-free picks in this comparison. Its wall-mount format and electronic ignition also make it easier to place than floor units that need more open space.

• Against the F299720, F299730 adds 10,000 BTU/hr of output and a larger stated heating area, 1,000 square feet versus 700 square feet.
• Against the 400,000 BTU Propane Heater, F299730 is the smaller-output choice at 30,000 BTU/hr, while that unit is listed at 250,000 to 400,000 BTU per hour.
• Against the DXH70CSFAVX, F299730 uses wall mounting instead of a portable format, so it suits fixed placement rather than a move-around setup.
• Against the Mr. Heater Vent Free Radiant Propane Heater, F299730 has the larger stated heating area, 1,000 square feet versus 300 square feet.
• Across these six heaters, F299730 sits third on buyer rating, with a 4.5 average from 3,418 ratings.

If you want the lowest price in this group, pick the CAMMOO Propane Heater instead; it is listed around $209.99, while F299730 is around $265.39. If your space needs a fixed wall-mounted heater with 30,000 BTU/hr, F299730 is the more relevant match.

Setting Up This Propane Heater, and What Support Covers

What you need before F299730 can heat a room

You need a propane supply, because F299730 runs on propane and does not require electricity.

1. Set the heater on the wall mount location you measured for a 1,000-square-foot heating area.
2. Connect a propane hose to a cylinder that matches the heater’s propane connection and fuel type.
3. Insert the AAA battery for the battery-operated electronic ignition.
4. Turn on the built-in adjustable thermostat and set the temperature you want the 30,000 BTU/hr output to support.

Warranty and support: what to check for this propane heater

Cover varies by seller and country, so confirm the details before your return window closes.

• Confirm the return deadline, because the electronic ignition and thermostat are the parts most likely to disappoint if anything arrives wrong.
• Confirm whether the seller covers the AAA battery and other included items, since the heater depends on battery-powered ignition.
• Confirm how propane-related claims are handled, because the heater’s indoor use and oxygen depletion sensor matter to safe operation.

Check the box contents on day one, and start the return clock while you can still act on any missing part.

F299730 Buying Questions Answered

How long will a propane tank last on the F299730 at normal use?

F299730 does not state runtime, so the tank-life answer is not given in the data. The listing does state 30,000 BTU/hr output, which tells you the heater’s demand level, but tank duration still depends on tank size and use pattern.

Is it worth paying around $265.39, or am I giving up anything important at this price?

The F299730 pairs 30,000 BTU/hr with wall mounting, electronic ignition, a built-in adjustable thermostat, and an oxygen depletion sensor. You are not giving up the core control features in this price range, but heating coverage is listed two ways: 750 sq ft and a maximum heating area of 1,000 square feet.

What matters more to you: a wall-mounted heater with no electricity required, or a portable unit you can move between spaces? F299730 is fixed to a wall and uses propane with battery-operated electronic ignition, so it favors a set installation over portability.

Can the F299730 run without electricity?

Yes, the F299730 runs without electricity. The listing says “No electricity required” and includes an AAA battery for the electronic ignition. That makes it a fit for outages where you still want a propane heater with battery-start ignition.

Does the F299730 need outdoor venting?

No, the F299730 does not require outdoor venting. The listing says “No outdoor venting required,” and it is marked for indoor use. That matters because vent-free heaters are chosen for room heating, while the tradeoff is moisture and combustion safety management.

Is the F299730 a good choice for a 1,000 square foot space?

Yes, the F299730 is listed with a maximum heating area of 1,000 square feet. That makes the stated coverage useful if your space is near that size and you want one wall-mounted unit. The same listing also gives 750 sq ft as heating coverage, so the tighter number is the safer planning figure.
