Buying Guide

Choose the right heat source

Propane delivers high BTU output and portability, while infrared models provide targeted radiant heat with generally lower fuel use for close-range warming

Match BTU to your space

Higher BTU ratings (tens of thousands) cover larger patio areas and withstand wind better; lower-BTU infrared units are effective for small groups or focused spots

Consider portability and fuel setup

Tank-top propane heaters offer easy transport and simple swap-and-go fuel; check whether a unit is designed for single- or double-tank use based on runtime needs

Prioritize safety features

Look for tip-over protection, stable bases, and clear control placements to reduce fire and burn risks during social events

Assess build and materials

Corrosion-resistant finishes and sturdy construction extend outdoor life; lighter portable models trade durability for easier repositioning
