About Product Overview

The Tank Top Heater LP 45000B from Mr. Heater sits right on top of a 20 lb propane tank, so there's no hose to run and no separate fuel canister to manage. It's built for outdoor jobs where you need real heat fast, whether that's a work site, a garage door left open on a cold morning, or an outdoor gathering that's run past sunset.

At 45,000 BTU, this convection heater throws off serious warmth for its size, and the plastic-and-steel construction is meant to take a beating in rough conditions. There's no thermostat and no electrical hookup required (0 amps, 0 volts), which keeps things simple: hook it to the tank, light it, and it runs. Keep in mind it's rated for outdoor use only and isn't UL or ETL listed, so it's suited for open-air spaces rather than enclosed rooms.

  • Fuel: Propane, mounts directly on 20 lb tank
  • Heater type: Convection
  • Construction: Plastic and steel, black finish
  • Rated for outdoor use only
  • 1-year limited parts and labor warranty

Price check

Go ahead. Check.

You're going to price-check us against Amazon, Home Depot, and Lowe's. Everybody does. Good — open all three tabs. We'll wait. Then look hard at what you're actually being handed over there.

On Amazon, start with these four questions before you click buy.

01

Who's actually selling it

The brand name is on the listing. A different company is in the seller field. Those aren't the same thing, and the second one is who you're buying from.

02

Whether the warranty survives

Most manufacturers only honor a warranty when the unit came through an authorized dealer. We're authorized for Mr. Heater. A third-party marketplace seller usually isn't.

03

Where the box came from

Gray-market stock, returns repackaged as new, and outright fakes move through marketplaces constantly. It all looks identical in the photo. It stops looking identical when it fails.

04

Who you call when it breaks

Ours is a phone number with a person behind it who has held this product. M–F, 6 AM – 5 PM Pacific. (866) 469-8556

The big boxes don't care if your hardware store survives.

Amazon, Home Depot, and Lowe's are built to pull every hardware dollar out of your town. When the local shop can't keep the lights on, the counter where somebody actually knew which part you needed goes with it. We're built the other way: real brands so you're never stuck on a marketplace, and a straight answer to buy it down the street when that's the better call. Support independent hardware — it doesn't restock itself.

Why we tell you to shop local

Shop Local · Support Independent

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
