Abstract
A forced air, wall heater includes a heat exchanger which has a plurality of tubes. Each of the tubes include substantially parallel aligned runs and at least one return section between adjacent runs. The return section is aligned generally perpendicular with each of the plurality of runs. The heater also includes a blower positioned for blowing air directly toward the return section to maximize the mass flow rate of air over the return section. At least two of the runs are offset both laterally and in the direction of air flow with respect to each other. The ordering of tubes differs in at least two positions within the exchanger.
