Mr. Heater MH540T 540° Tank Top
#9 in Tank topFull review
For crews on open job sites, loading docks and sidelines who want the most heat a single tank top gives, in every direction. Use it only where fresh air moves freely.

2.6/5
For job sites, ice fishing and outdoor work where a simple, repairable 15,000 BTU tank top from a known maker is worth a little more. Use it only with plenty of fresh air.

Pros
- Runs up to 43 hours on a 20 lb tank on its low setting, by Mr. Heater’s figures

Cons
- Lit with a match, which is awkward in wind and with gloves on
- No safety listing mark named, though the manual cites the construction heater standard
- Not for homes, campers or tents: construction sites with ventilation or outdoors only
- Costs more than budget 15,000 BTU tank tops

#11 in Tank topFull review
For occasional outdoor use where a cheap 15,000 BTU tank top with tip-over and flame-out shutoffs is enough. Keep it outdoors, since the listing gives no ventilation rules.
