Many homes in the Denver area are heated with boilers, which heat water and provide heating throughout the home.  There are high-efficiency versions of nearly every type of boiler, but some kinds of boilers are inherently more efficient than others.  Here is a look at the efficiency ratings that are given to various boiler types.

The efficiency of heating equipment is measured in annual fuel utilization efficiency, or AFUE.  An AFUE of 85 means that 85 percent of the stored energy in the fuel source becomes heat.  The other 15 percent escapes through a ventilation system.

• Gas-fired water boiler – Fueled by natural gas or propane, this type of boiler can achieve AFUE ratings of around 80-90.  The affordability of natural gas in Rocky Mountain West makes this an ideal choice for Denver residents.
• Steam boiler – These operate at a higher temperature than hot water boilers and they are less efficient as well.
• All-electric boiler – There is no energy lost through the chimney when you choose an all-electric option, allowing for AFUE ratings of 95 to 100.  These near perfect ratings are afforded to boilers that are installed inside, since outdoor units suffer more from jacket heat loss.  Keep the cost of electricity in mind before you jump to this option because of the high efficiency rating.

The bottom line is that you want a new boiler in your home that will run reliably and in a fuel-efficient manner.  A great way to know you’re getting an efficient system is to choose an Energy Star labeled product.  There is a wide selection of options at Coffman and Companies in the Denver area.  Contact this reliable HVAC company by visiting our websiteor calling us at (303) 366-1112.
