Heating FAQ

Which size of furnace do I need to heat my home?
Furnace size is dependent upon several factors including type of heat used (forced air, baseboard or radiant), square footage, ceiling height and insulation levels. Additional considerations include plans to heat future buildings, heating your domestic hot water along with existing heat consumption (if applicable).

We have general guidelines for new construction which give you a fairly good idea of which furnace should be used. However, the best way to size a furnace is to know the historical fuel consumption for heating an existing structure, then convert that through our sizing guide to the best outdoor wood furnace size. We also have ways of sizing buildings like shops that have higher ceilings and different heating needs from typical living space.

What is the efficiency of the Classic Edge and E-Classic?

Central Boiler certified furnaces top the EPA list for efficiency with an 85% efficiency as the high. The average of these furnaces is about 80%. When operated in the same way, these furnaces will give you similar results. While Central Boiler furnaces are labeled with these efficiencies that were derived from the EPA Certification tests, actual efficiencies can be as high as 97% in some furnaces based on certain factors such as wood selection, moisture content, ash level, draft, fire heat and length of burn.

How do I determine which EZ Floor product options is best for my project?
Factors including where the product will be installed (slab-on-grade, slab-above-grade, snow melt, etc.) and whether your project is a new build or retro-fit make a difference in this decision. Our standard 2" R-10 value product is best for main level residential use, most slab-on-grade projects like shops, garages and snow melts and most slab-below-grade projects like basements. Sometimes a project calls for a 3" version, R-15 version, but usually the 2" product is the perfect choice. If you are installing a second floor application, a 1" R-5 value lighter product should be used. Consult your radiant designer or give us a call for a free consultation.

Why is the insulation in EZ Floor radiant floor insulation panels better than the competition?

EZ Floor radiant floor insulation panels use EPS foam insulation while typical pink or blue board-type foam panels use XPS insulation. EPS foam has a 94% heat retention factor while XPS has a 52% retention factor. Both insulation types will start out with an R-10 insulating value for a material thickness of 2", but over time the XPS foam will lose about 48% of its R-value rating while the EPS foam will only lose 6%. Essentially it takes 4" of XPS foam to equal the same long-term R-value protection as 2" of EPS. This significant difference translates into using increasingly more fuel year after year to heat with XPS insulation versus staying consistent from year to year if you use EPS. Clearly the EPS foam found in EZ Floor is a superior product that will save far more money over the years than other types of foam insulation.
