In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

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.

About Product Overview

Meet the Mr. Heater Big Buddy, a compact propane-powered radiant heater engineered to bring focused warmth to mid-sized spaces. With an impressive 18,000 BTU per hour output and a heating range up to 450 square feet, this portable unit delivers fast, direct heat where you need it most—garages, workshops, basements, cabins, or any well-ventilated indoor area.

Why this Big Buddy stands out:

  • Rad iant warmth focused where you stand: Unlike convection heaters that warm air, the Big Buddy sends heat directly to you and nearby objects, making it ideal for drafty or partially insulated spaces.
  • Indoor-ready design with safety in mind: CSA listed for safety, built with a robust but portable plastic body, and a compact footprint that fits where storage is tight.
  • Automatic Delay Shutoff: A built-in safety feature helps prevent overheating and allows for controlled, gradual shutdown.
  • Simple, reliable operation: Fueled by liquid propane, this heater doesn’t rely on electricity to generate heat, making it a dependable option in areas with variable power availability.
  • No built-in thermostat by design, giving you straightforward heat output control based on your environment and fuel supply.

Ideal applications

  • Small to medium spaces that need quick warmth without running a full heating system
  • Workshops, garages, and basements where durable, portable heat is a practical solution
  • Cabins or temporary spaces where a reliable, propane-powered heat source is beneficial

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
