Use-case guide · 2026
In a leaky house, heating the air is a losing game — it escapes as fast as you warm it. The winning strategy is to heat people and zones instead: infrared that warms you directly, a heated mattress pad at night, one good heater in the room you're in, and the furnace set lower everywhere else. And an afternoon with weatherstripping and plastic window film beats any heater upgrade.

Radiant (infrared) heat aimed at where you sit, plus reducing the drafts. Infrared warms you directly rather than warming air that leaks away, so it feels effective even while the room itself stays cool. Seal what you can first — the heater then has a fighting chance.
It can be, if you use them to zone-heat one or two occupied rooms while lowering the whole-house thermostat several degrees. Running multiple space heaters to heat the whole house is almost always more expensive than the furnace.
