Best Patio Heaters Under $100 (2026)

The HETRAROOT is a 1500 watt PTC ceramic tower marketed for porches. PTC ceramic limits its own element temperature, and a DC fan motor with an engineered impeller is claimed to move more air at lower noise. Four heating modes and 70 degree oscillation let it spread warmth across a seating group instead of aiming at one chair.

It makes about 5,100 BTU per hour, the same as any 1500W electric heater, and that heat is carried by moving air. On a still evening under a roof this works well for a few people; in a breeze the warm air disperses and the effect fades. Compared with the SEEYANG, it is taller and sweeps wider, which suits a seating area better than a single chair.

Treat it as a covered-porch heater. Keep it out of rain, plug it directly into a weather-protected outlet, and keep three feet from furniture covers and curtains. Dust the intake monthly and bring it inside for the off-season. Think about the surface it sits on: a damp porch floor and a plug-in appliance are a poor mix, so lift it on a dry mat and keep the plug off the ground. Bring it indoors when frost or rain is forecast, and wipe the grille dry before the next use.

Buyplus sells a 1500 watt PTC ceramic heater with three modes: fan only, 750 watts and 1500 watts. A self-resetting heat breaker cuts power if it overheats, and a non-slip base helps it stay put on a concrete floor. It is listed for garages and patios.

The fan-only mode matters because it gives the unit a second life as a summer fan. Compared with the HETRAROOT it lacks oscillation and the tower shape, so it warms the area directly in front of it. That suits a workbench in a garage better than a seating group on a porch.

Keep it dry, plug it into the wall and give it clearance from boxes and fabric. It will not warm a garage or a deck in cold wind, so use it in a closed space. A garage is where this style shines, since the space is closed and the heat only needs to reach a person at a bench. Point it at your hands and torso, keep cardboard and solvent cans well away, and never leave it running unattended in a workshop.

Joanolga lists a 1500 watt PTC ceramic heater with three adjustable heat settings from a low fan setting up to the full 1500 watts. The listing positions it for greenhouses and patios, with a notable coverage area claim. A three second warm-up claim describes how fast the air at the grille feels warm.

In a closed greenhouse it can hold a seedling bench above frost for a night, which is a real job at this price. Outdoors on an open patio, the coverage claim is optimistic. Compared with the Buyplus, the specifications are close, and the choice is mostly about price and finish.

Use it in a dry, sheltered space with a weather-protected outlet. Seedlings tolerate cold better than a warm-up and a crash, so run it on a low step through the night and check the bench temperature with a cheap thermometer. A thermostat plug adds control that the heater itself lacks. If the bench temperature drops below freezing even with the heater running, the greenhouse needs insulation more than it needs another heater. Bubble wrap on the glazing makes a larger difference than a second unit.

SEEYANG pairs a 1500 watt PTC ceramic element with a 2600 RPM fan and three modes, including a 25 watt natural-air setting. It is the most basic unit here and is marketed for garages and greenhouses as well as patios. The listing leans on quiet running and fast heating.

A high-speed fan moves air quickly but does not change the heat output, which stays at 1500 watts. It is the cheapest way to warm a covered nook.

Use it dry, in a sheltered spot, and unplug it when you leave. Think of it as a shelter heater for an hour or two. If you sit within a couple of metres, aim it at your legs and expect the warmth to feel good on a still evening, and do not expect it to change the air temperature of a deck. Because the heater is basic, the thing to spend attention on is placement and plug care. A low-cost unit that is positioned well beats a better unit that is positioned badly.
