Craftsman 60,000 BTU Forced Air

This unit is built for people who need reliable heat in a garage, workshop, or barn. It’s a forced-air propane heater that covers up to 1,500 square feet. Craftsman targets homeowners and hobbyists who want a familiar brand with solid construction.

The standout feature is the adjustable heating angle. You can aim the hot air exactly where you’re working. The electronic ignition means no matches or lighters – just push a button. Variable temperature control lets you dial in 30,000 to 60,000 BTUs, so you’re not blasting full power on a cool fall day.

But there’s a catch: this model is currently out of stock. If you need a heater today, you’ll have to wait or look elsewhere. Also, forced-air heaters are loud. Craftsman doesn’t claim quiet operation, so expect a constant roar. It’s not ideal for living spaces.

• Covers 1,500 sq ft
• Adjustable heating angle
• Electronic ignition
• Variable rate temperature control
• Currently unavailable – check stock

Best for: Home workshops where noise is acceptable and you can wait for restock.

Suburban ST-60 Tankless

This one is completely different – it’s a tankless water heater for RVs. That’s right, not a space heater. But if you need 60,000 BTUs for endless hot water in your camper or motorhome, the Suburban ST-60 delivers. It’s designed for RV owners who boondock or want on-demand hot water without a bulky tank.

Suburban packed in serious safety: flame-out protection cuts gas if the burner malfunctions. Scald protection keeps water under 131°F. A child lock limits output to 113°F. Active freeze protection kicks in when temps drop, as long as power and propane are connected. These features make it a top pick for families with children.

The trade-off? You’re buying a water heater, not an air heater. It won’t warm your garage. Installation requires a separate door kit (sold separately) and the digital control panel comes included. Also, it only runs at a fixed 60,000 BTU output – no low-power mode for summer showers.

• Enhanced flame-out protection
• Scald protection (max 131°F)
• Child lock (max 113°F)
• Active freeze protection
• Voltage protection shuts down on power issues

Best for: RV owners who want safe, on-demand hot water with robust safety features.

Flame King Propane Heater

Flame King builds portable forced-air heaters for jobsites, patios, and garages. This 60,000 BTU model heats up to 1,500 square feet and runs up to 8 hours on a 20-pound propane tank. It’s a straightforward workhorse for contractors or anyone needing spot heat in open, ventilated spaces.

The safety package is comprehensive: a fuel shutoff, fire detection system, and tilt shutoff. If the heater tips over, it stops. The auto piezo ignition sparks instantly, and the gas control button lets you adjust output. Construction crews appreciate the stainless steel body that stands up to rough handling.

But it’s not for indoor use. The manual says open, well-ventilated areas only – garage use requires maintaining adequate airflow. Noise is standard for a forced-air unit. The 8-hour runtime on high is decent, but you’ll need extra tanks for all-day jobs. No variable BTU range – it’s either full 60,000 or off.

• 1,500 sq ft heating area
• Safety tilt shutoff
• Auto piezo ignition
• Stainless steel body
• 8 hours runtime on 20lb tank

Best for: Jobsite use where durability and safety shutoffs matter more than quiet operation.

Mr. Heater Quiet Burner

Mr. Heater’s QBT (Quiet Burner Technology) makes this unit 50% quieter than standard forced-air propane heaters. That’s a huge advantage if you’re working in a garage near a house or want to hold a conversation without shouting. It heats 1,500 square feet and runs up to 14 hours on low setting with a 20-pound tank.

The variable output from 30,000 to 60,000 BTUs gives flexibility – you can save fuel on milder days. Continuous ignition means the flame stays lit without repeated sparking. Build quality is typical Mr. Heater: rugged, reliable, with good customer support. For noise-sensitive environments, this is the clear winner.

No heater is perfect. The QBT technology adds cost – it’s usually pricier than comparable units. The continuous ignition can drain batteries if you forget to shut off the power. And like all forced-air units, it still makes noise; it’s just less annoying. Also, not suitable for indoor use without ventilation.

• QBT – 50% quieter than standard
• Variable 30,000–60,000 BTU
• Heats 1,500 sq ft
• Up to 14 hrs runtime on low
• Continuous ignition

Best for: Garages or workspaces where noise is a concern and you want the longest runtime on a single tank.

How We Chose These Products

We started with a clean list of 60,000 BTU propane heaters available on Amazon. Each had to deliver real utility, not just specs. We prioritized safety features, build quality, and real-world usability. The Craftsman and Mr. Heater came from the forced-air space heater category. The Suburban is a specialized RV water heater. The Flame King is a direct competitor to Mr. Heater but at a lower price point.

We also looked at customer feedback patterns – what people actually complained about. Noise, ignition reliability, and fuel consumption stood out. The Mr. Heater’s quiet technology addressed a major pain point. The Suburban’s safety suite justified its inclusion even though it’s a different product type. The Craftsman would have been our budget pick if it were in stock.

Buying Guide: What Really Matters

First, decide what you’re heating. Air or water? For space heating, forced-air units are loud but effective. For RVs, a tankless water heater like the Suburban is a different beast. Don’t mix the two. If you need both, you’ll buy two separate products.

BTU output matters, but variable range is more useful. A fixed 60,000 BTU unit either blasts full heat or nothing. Variable models let you dial down to 30,000, saving propane and reducing noise. The Mr. Heater wins here. Also check runtime: the Mr. Heater’s 14 hours on low beats the Flame King’s 8 hours on high. Longer runtime means fewer tank swaps.

Safety can’t be ignored. Tilt shutoff, flame-out protection, and overheat sensors are worth paying for. The Suburban’s child lock and scald protection are unique but only relevant for water heaters. For space heaters, forced-air units need stable placement – a tip-over switch is standard on good ones.

Our Top Recommendation

The Mr. Heater Quiet Burner is the best overall 60,000 BTU propane heater for most people. It’s quieter, runs longer, and offers variable output. The 50% noise reduction alone justifies the extra cost for anyone who works in a garage or spends hours near the heater. If you prioritize quiet and fuel efficiency, this is your pick.

If you need serious safety for an RV water heater, the Suburban ST-60 is the only choice here. It’s not a space heater, but for its job it’s excellent. For budget-conscious buyers on a jobsite, the Flame King gives you solid build and safety shutoffs at a lower price – just accept the noise and fixed output. The Craftsman would be a good middle-ground if Amazon ever restocks it.

Frequently Asked Questions

Can I use a forced-air propane heater indoors?
No. The user manuals for Flame King and Mr. Heater explicitly say only in open, well-ventilated areas. Garages are okay if you keep doors open or have adequate airflow. Never use them in a house or enclosed room without ventilation.

How long does a 20-pound propane tank last on a 60,000 BTU heater?
At full output, roughly 8 hours for the Flame King and Mr. Heater on high. On low setting (30,000 BTU), Mr. Heater claims up to 14 hours. Actual time depends on outdoor temperature and wind. Keep a spare tank handy.

What’s the difference between forced-air and tankless water heaters?
Forced-air heaters blow hot air into a room. Tankless water heaters heat water on demand for showers and sinks. They use the same BTU rating but serve completely different purposes. Don’t buy a Suburban ST-60 expecting to heat your garage.

Do I need a special regulator or hose for these heaters?
Most come with a hose and regulator in the box. Flame King includes a LP hose with built-in regulator. Mr. Heater and Craftsman require a separate hose assembly if not included – check the product listing. Always use a regulator rated for the BTU output.
