The process of heating a home starts when the thermostat measures a room's temperature. When a conventional thermostat switches the boiler on, the boiler will fire at full-blast for as long as it takes to heat the entire room to the desired temperature.
As a consequence of firing the boiler for so long, the water gets heated to a higher temperature than what is necessary to maintain a room at comfortable levels.
This ultimately results in wasted fuel consumption and higher heating bills.
While a conventional system will heat the water to temperatures as high as 200-degrees, an efficient system will allow that to occur only when the outside temperature drops to below-zero.
Unfortunately, a conventional system only knows what the temperature is inside the house, firing the boiler just as hard, regardless of the outdoor temperature.
Considering that below-zero temperatures occur in our area only about 2 percent of the year, while temperatures above 30-degrees occur more than 80 percent of the time, it makes better sense to fire the boiler accordingly. By installing a sensor on the north side of the building, the temperature of a home's hydronic system can be regulated according to the outdoor temperature.
On the rare times when the temperature drops to 10-below, the boiler will raise water temperature to whatever (generally about 200-degrees) levels are needed to offset the increased heat-loss caused by extreme weather conditions.
On the other hand, when it is 30-degrees outside, and the rate of heat-loss is substantially lower, water temperatures can be maintained at levels as low as 135-degrees.
As a general rule, for every three degrees a building's heating supply water temperature is reduced, fuel consumption is reduced by one percent.
A byproduct of these controls is increased comfort.
Because these systems do not follow the on/off principle, there is always just enough heat flowing through the distribution system, eliminating temperature swings.
