Temperature simply divide the flux by 2 and add the result to the desired operative temperature. The floor can’t be too hot (max 84˚F, ANSI/ASHRAE Standard 55-2004) or it will be uncomfortable and if it isn’t warm enough it may not be able to transfer the Btu’s. One of the critical but simplest calculations to perform is the floor surface temperature. Here's how we categorize buildings based on flux. You want to try guessing 100 or 1? Not a good idea. Imagine theĮquivalent heat of 10 matches burning per hour every square foot. If your heat loss calculation shows you need 10,000 matches in an hour and your available floor area is 1000 sq. We’re not talking about soldering here we’re looking at how many matches must burn per hour per square foot. Learn what types to use and not use by clicking here.

High performance walls and ceilings and usingĬlimate appropriate windows and doors. Note: Heat loss can be reduced by selecting and placing suitable So do you got it? You have to do 1 before How many burning matches is it going to take to keep the place warm? How many gallons are going to have to circulate through the floor carrying those matches? The heat loss calculation provides answers to these questions and you can’t go to You shouldn’t be guessing in hydronics either.

Stairs? In any other profession whether it’s a doctor, a cab driver or the teenager selling burgers – no one wants to hear guessing as to how much when it comes to paying for anything.

Times you'd have to haul a 55 lb weight up a set of Is it 10, 100 or 100,000?Īnother way to look at a single Btu is about the sameĪmount of energy it would take to haul a 55 lb weight upĪ 10 ft flight of stairs. Must burn in an hour is what we’re talking about. For my non technical accountant friends I describe a Btu as the amount of heat a match puts out. One can’t begin to think about materials or assembly until this key calculation is done. Heat loss influences everything in the design process. Hydronic underfloor radiant heating systems, the systematic design process can be described as a 12 step program beginning with the heat loss and ending with the head loss.
