"We had AHT Inc. replace our heating system, a 1987 vintage 150,000 BTU Power vented propane gas boiler and an 80 gallon indirect fired water heater with baseboard radiation. They installed a Viessmann Vitocell 200B dual coil indirect water heater, using our old water heater for supplemental space heating and replaced the baseboard with Radson panel radiators. In addition, they installed 64 Vitosol 200 vacuum tube solar collectors to supplement our hot water and radiant heating. We didn't do any substantial building or envelope improvements and in fact ended up adding an additional 1600 square feet of space with two new residential apartments. In one year our fuel consumption dropped from 1679 gallons to 960 gallons, even after we added an additional 1600 square feet of space. The installation of the new condensing gas boiler and solar panels to supplement our hot water has provided a huge savings for us. Thanks AHT Inc.!"

"Based on a friend's recommendation, I asked AHT Inc. to provide an estimate for major work on my heating system. I had been thinking about radiant floor heat and at the same time I needed to replace my furnace and wanted to replace the copper pipes embedded in my slab with pipes running in the walls so they would be easier to reach in case of leakage. Ed and Ben came and spent a good deal of time going over what I thought I wanted… They suggested the alternative of radiant wall panels that have been used in Europe for many years and would be a simpler and less expensive retrofit.

After agreeing to the estimated system, Ben and his crew (Christian and Stu) spent a week doing the installation. I had been dreading the disruption of that amount of work but they made it easy for me. They kept me informed, were very professional, quiet, patient and cleaned up at the end of each day. They all worked very hard and did a beautiful job. This past winter (my first with the new system) made me realize how much I had been missing. I set the temperature higher than I used to and between that and the lack of cold air currents with the panels, it's the most comfortable winter I've had. My fuel consumption was down about 30% (based on estimated degree-day adjusted usage for the season so far). The panel in my bathroom has turned out to be a wonderful towel warmer too! I've only had a couple of very minor issues and Ben or Christian responded very quickly. I'm totally satisfied with the process and result, I don't see how it could have been better!

During the coldest month of this past winter we had a 38 day bill for heating (propane). My bill was $238 whereas my neighbors with similar [housing] units (some of which were inside units while mine is a colder outside unit) were paying somewhere between $300 up through $650. I set my Thermostat between 64 and 66 during the day and 59 at night. Some of my neighbors kept their units at a max of 60 degrees whereas the really high ones were set at 68-70."

"In March 2009, AHT converted our existing forced hot air oil heating system to a forced hot water system using the Viessmann Vitodens 200 gas fired condensing boiler, Radson radiators and a Crown Megastar stainless steel indirect water heater. They did an efficient professional installation job, on time and on budget. Each day they cleaned up after themselves and they left our basement cleaner than they found it, removing the old duct work and furnace. We appreciate the time that was taken to demonstrate and instruct us how to use the system, answer our questions, provide us with a notebook full of documentation, and they are always available to answer questions. We look forward to living with our new system through the next winter season."
