Pelonis has been making affordable, reliable space heaters for years. The PHO15A2AGB oil-filled radiator is their core model, a straightforward appliance that prioritizes steady, silent warmth over flashy features. It’s a workhorse for heating a bedroom or home office.

Heat comes from thermal oil, which the electric element warms and circulates permanently sealed inside the metal columns. This means no fan noise—just radiant, consistent warmth that doesn’t dry out the air like forced-air heaters can. The three power settings (600W, 900W, 1500W) and adjustable thermostat let you match output to the room size and your comfort. It’s energy-efficient because the retained heat lets the thermostat cycle the power off more often.

Built-in tip-over and overheat protection are essential safety features. The unit is heavy when filled with oil, but the integrated wheels make it portable. It’s a simple, effective solution for all-night warmth without the whir of a fan.
