Boilers Part 11 – Reset

by

Today we will discuss RESET. Reset is the ability of a boiler to change the water temperature in your radiators to meet your specific heating needs in real-time as the outdoor temperature changes. A standard boiler will typically keep your radiators at 140 degrees Fahrenheit. On really cold days, this is great. For milder days however, your radiators don’t need to be so warm. When it is just a bit cool outside, 90 degree Fahrenheit radiators would be enough. As it gets colder outside, your radiators would need to warm up to keep your house warm. A boiler with the Outdoor Reset feature will constantly measure the temperature outside and adjust your water temperature to give you just the right amount of heat. Now that’s what I call efficient.
In my next post I will illustrate the typical heating cycle without outdoor reset.

The following video is a great simulation of what happens in my favourite DVCB, the Triangle Tube Prestige during a heating cycle. Check it out!
