"When we built our home we had a new concept of placing our daughters bedrooms in the basement.  Our water furnace has provided us with the warmth and security we were looking for.  I love the fact I don't have to worry at all about Carbon Monoxide poisoning."

"In the seven years since we have had our system installed we have not had one service call."
" When we built our dream home we knew we wanted a Waterfurnace based on the recommendation of a friend who built a very large home that actually won Kansas City home of the year recognition.  It was important to us to have an HVAC system that could inexpensively and effectively dehumidify and cool a home comfortably during Missouri's hot humid summers.  After  we decided a Water Furnace was the best way to go, we need to choose a dealer.  We wanted the best quality work for the best price.  When he asked direct questions of knowledgeable industry sources, we was surprised to hear that the best work and the lowest prices were delivered from the same shop."  "We did not even consider a conventional heating & cooling system.  Rehagen has a terrific team, and they really deliver solid value.  We are totally satisfied."

"We have a Water Furnace in both our home and Wine making barn.  Our wine making barn is most impressive, it is over 6,400 sq. ft. that is conditioned year round.  Our highest bill ever was $113.00 and that is for 6,400 sq. ft. building!"  

The owners of Westphalia Vineyards are currently in the progress of having Rehagen HVAC install a 26 ton Water Furnace Geothermal system in their newly purchased Historic Westphalia Inn  Restaurant and Norton Wine Tasting Room.  The past owners of the Inn have always been plagued with heating costs so high it would force them to close during the winter months.  They knew with out a doubt that a geothermal system would be the only alternative!  To view a list of their award winning wines  from the Westphalia Vineyards click here.  Our personal favorite is the Anna Rose`!
Fusion Welding Iron
The Fusion Irons reach temperatures of over 500 degrees!  A test on the pipe connections was performed by hooking pipe with welds to heavy machinery.  The pipe itself broke and not the welded joints!

Unlike Air to Air Heat Pumps,  Geothermal Heating and Cooling systems are not dependant on the outside air temperature to make heating and cooling, therefore you do not need to have a back up heat source.  The ground temp. in Central MO will stay around a constant 58 degrees, no matter what the weather outside is doing!
