Meter to feet Length ratio=3.3 (One meter equals 3.3 feet) Sq.meter to sq.feet area ratio= 10.76 (One square meter equals 10.76 square feet) In order to get the feet equivalent, you just have to multiply the meter amount with the length ratio (3.3) to get the amount of feet, or divide the feet amount by the length ratio to get the meter amount. For areas and spaces, just multiply the square meter amount with the area ratio (10.

The heater model and capacity are not necessarily a function of the square footage of the area needing to be heated. The model generally is chosen after the Btu/hr heat loss for the building or spot area to be heated has been determined, which is a function of not only the size of the area, but geographic location, building materials, building usage and other factors. Area coverage could be as little as 500 sq. ft. or as much as 10,000 sq. ft.

There are many variables that dramatically affect heat loss, but here are some general guidelines, based on a new construction radiant slab, well insulated (walls, ceiling and under slab), in a moderately cold winter climate area using a thermostatic mixing valve: A standard 50 gallon electric water heater with (2) 4500 watts elements and a 20 gallon per hour (gph) recovery rate can usually heat about 250 sq ft.

Individual unit specifications reflect effective square footage coverage based on a relatively unpolluted environment. The amount of pollution, air flow conditions, and the specific layout of the environment will determine the number and size of units needed. Although there are a few rules of thumb, nothing can be more helpful than conversing with those who have experience. Also reference Document #4235 from the FAX on Demand system.
