Customer support begins with a great customer service team. Our dedicated team is trained and experienced in all things outdoor boiler. You can always expect a human on the other end of the line. We know what’s important to you - your family, saving money, and keeping your house toasty warm - and we make that our highest priority.
One of the most important steps in prolonging the life of your outdoor boiler is to ensure that the water in your boiler is not corroding the steel. Water starts to eat holes in steel immediately upon contact (through rust corrosion) unless properly treated. We test your outdoor boiler water for free!
