| Folks often ask how we know Exquisite Heat savs on fuel consumption. Below is a quote worth mentioning. The advantage of Exquisite Heat is that it adjusts the temperatures every hour of the day. This gives added advantages to the 20 degree difference between noon and midnight all winter plus the mid winter warm periods. Exquisite Heat provides the proper temperature of boiler output for steam, hot water and hot air.
Aquastats. The thermostat that regulates the temperature of a hot water boiler is called an aquastat. Normally, the aquastat keeps water in the boiler around 160-180ºF. In milder weather, however, you don't need to keep the boiler that hot. The aquastat can be set manually to 140ºF (120ºF with condensing boilers), reducing fuel consumption by 5-10%. The aquastat control is usually located in a metal box connected to the boiler. If you can't locate it, ask your service technician for assistance. Your technician can also provide information on modulating aquastats (or outdoor resets) that automatically adjust water temperature depending on the outdoor temperature.

You can see from the reset technology by Taco, that outdoor resets make a significant savings. Exquisite Heat trrechnology is considerably more attractive as the reset is accomplished from real time datat from the inside thermostat, rather than the outdoor sensor. Exquisite Heat is comfort conscious by demanding the temperature be corect to satisfy the 60% circulation rate. This assures even comfort in all rooms.
A word about heat loss in buildings. Every building has a different relationship with its heating system. The only accurate way to keep even comfort is to first establish good circulation from the system at all times and then to reset the boiler to meet the BTU needs at that rate of circulation. This kind of precision is not available from outdoor reset technologies.
