Wwe made a deposit and will pay another 80% this Friday.. I lookedand looked. Most heating co's around here still believe in huge cast iron boilers. I wanted something different. In researching (4 months in depth at least if not more) system 2k kept coming up. Wrote the company in Jersey, read what they sent. Then, 2 weeks later, an offer for a list of recent and older customers plus their highest rated installers. Energy Kinetics offers yearly schooling and not all installers attend. One name kept pooping up and I called that installer. Very professional, made thre trips to the house. We walked every inch from cellar to second floor. I asked about one thing, he said it's too costly, go this way.. And on and on it went. I flet extremely comfortable with this outfit and took the plunge. For one, no super sized cast iron boiler, running at 70 - 75%. He offered limited life time guarantee on most of thesystem and other key components, 5 yrs. Written guarantee of 800 gallons max useage per year. Remember, our house is on a slope up from a reservoir, so the wind and snow really hammers pretty hard. Including the cellar of 1800 sq ft, first fl same, and 1200 sencond floor, all plaster walls, no sheet rock, he offered the best installation system. Best fuel use etc.. Finally found another person with same thing installed two years ago on other side of reservoir. Very cheap oil bills and no complaints. I believe I made the right decision or at lest hope so.
