After almost 3 weeks of waiting its finally here and ready for the cold weather. The 2 gentleman that came out did a great job. very clean. didnt leave any mess and were vey professional. It took about 6 hours, 3 of that was just getting through the foundation. I have a concrete and stone foundation with a brick house built in 1949. They didn't like the 15 inch thick foundation too much. It was a basement install as I didn't want to pipe in a new zone for oil. didn't feel like wasting more money on oil. I also went out and bought a Lux thermostat cause the one the quad came with was pretty simple. Thanks Don2222 for alittle help with the Lux.
