Easy, innovative solutions for making your garage
more usable and comfortable
Comfort for Your Family
Protection for Your Car
Getting in and out
of the car is more
comfortable when
you have a garage
heater. Plus, you
can avoid the carbon monoxide
buildup that comes from letting your
car idle to warm up.
A warm garage
puts an end to
cold starts, which
can wreak havoc
on engine components. A garage heater helps improve
vehicle reliability by preventing cold/
hard starts at low temperatures.
Warmth for Your Pets
For pets kept
in the garage
on cold days,
a garage heater
provides a safer
and more reliable alternative to a
portable space heater.
Space for Your
Projects
A garage heater
helps keep winter
from getting in
the way of home projects. It also
allows you to store items that would
otherwise freeze, like bottled sodas
and potted plants.
