3 Ton WaterFurnace Envision system. Ground water in this Emmett area is abundant and close to the surface which is excellent for open loop systems. This homeowner was able to discharge into a warm water slough on his property and save money in initial install costs. As with all our systems, the Hot Water Generator (HWG) is included. The HWG connects directly to a stand alone water heater. Whenever the unit is either heating or cooling the home, it is also injecting heat into the water heater to provide additional savings. This energy is absolutely free in the summer (heat is a by-product in cooling mode). After a month the customer said the same thing we’ve heard many times…”For some reason we’re keeping our house 2 degrees cooler than in the past? It just feels warmer and we’re comfortable there.” The system doesn’t dry the air like gas furnaces and provides more even heat due to longer run cycles. This makes the home feel warmer at the same temperature on the T-stat.
