Welcome to our Radiant Heaters collection, your one-stop source for compact, energy-saving infrared units that warm people and objects directly, rather than wasting heat on the surrounding air.

Our current line-up is built around the field-proven Sunstar Heating Products brand. From low-profile plaque heaters that mount flush to the wall to glass-front patio models that blend seamlessly into upscale décor, Sunstar delivers dependable radiant comfort with minimal operating costs.
Looking for something a little different? Pair these heaters with accessories from our other collections—such as smart thermostats for hands-free scheduling or durable unit heaters for forced-air backup when needed.

FAQ
What’s the difference between radiant and convection heat?
Radiant heaters warm people and objects directly, so you feel heat faster and lose less energy to stratification.
Can I convert a natural-gas model to propane?
Many Sunstar units ship with separate LP or NG orifice kits—check the spec sheet or ask our tech team before ordering.
Do vent-free heaters add moisture?
A small amount; always follow clearance requirements and supply adequate fresh air.
Are these safe for bedrooms?
Only models that carry an ANSI-approved oxygen-depletion sensor (ODS) are bedroom-rated. Review the manual before installation.
How long is the warranty?
Sunstar offers a 3-year parts warranty on most radiant models; see individual product pages for details.
