Radiant Heating Installation & Services


Radiant heat is a very maintainable, healthy heat that is absorbed by the environment around it. Radiant heat keeps your home warm longer and more consistently, instead of overheating which causes heat loss.

Many studies have been conducted that indicate that physical warmth makes people more happy and pleasant to be around. This is why radiant heat has become as popular as it has been over the years.

SJ Kowalski Inc is committed to providing homeowners with the luxury they are looking for, our products supply cozy and comfortable warmth.

  • Clearing the Air
    We know that forced air systems blow hot air in your home, but what most of us don't realize is that forced air also pushes dust, allergens and other airborne particles in every room.
  • Healthy Living
    By improving indoor air quality we can reduce many occurrences of asthma, allergies, medical bills and more.
  • Reduce Pollutants
    Studies show that dust mite populations are reduced by as much as 90% in radiant heated homes.
  • Relax at Home
    Quiet and peaceful environment, free of noisy fans and blowers.
