Warmair.com Inc., a heating and cooling Internet company, has launched www.heatload.com, featuring a calculator that allows site visitors to calculate heat loss/gain.

The conventional calculator is customized to determine Btu requirements for a residence and selects the correct Thermo Pride gas or oil furnace, Burnham boiler, and/or amount of Slant Fin baseboard needed to satisfy heating requirements. The Unico System of mini-duct air distribution has been added as a special feature.

In conjunction with Warmair’s partnership with ImproveNet.com, heat load.com will be featured as a direct link from the ImproveNetpro website.
