What is a fully modulating furnace?

What is a modulating furnace? A modulating heating system uses a burner that adjusts incrementally the amount of fuel burned to maintain a constant temperature. A furnace can have a variable/multispeed blower or a modulating burner. This provides the best heating possible.



Is a modulating furnace worthwhile?

A modulating gas furnace is a great investment if you intend to live in your home for many years. Although they are more expensive than their single-stage and two-stage counterparts but offer superior efficiency, especially if you live in a newly constructed home,

Commercial boilers have a range of turndown ratings from 3-1 to 10-1. High turndown is used in commercial boilers to reduce burner cycling and maintain consistent temperature or pressure.

This is why we ask you to consider the pros and cons of modulating vs 2 stage furnaces.

Modulating furnaces with two stages and modulating furnaces allow the system run at lower, more efficient levels. This provides more consistent comfort. 2 stages. These models can be set to run at 50% or 100% depending on the need.
