Regenerative blowers are portable, low-pressure air sources that are ideal for use with many Tutco SureHeat Air Heaters.

Proposition 65 is regulation originally passed in 1986 by California to alert consumers in California of items which may pose a risk of cancer or birth defects.

Watt density is a useful measure when considering the various types of heating elements available. Learn about watt density and open coil elements.

Calculating the wattage requirements to heat a system is a straightforward process as long as all the parameters of heat energy flowing in and out of a system are considered.

A diode in series with the heating element will reduce the applied energy to the heater for a given voltage and allow a larger lower resistance heating element to be used.

What is the difference between a distributed wattage heater and a zoned heater? Almost any heater that uses a wound coil can use one of these construction methods of controlling watt density.

Duct heaters made by TUTCO-Farnam are not for HVAC use. They are for industrial type applications and are not built to the standards required for the typical residential HVAC.
