Product Description: Thermasi Furnaces are designed for new construction or direct replacement for existing furnaces and reheat boxes. Thermasi furnaces can also be installed in numerous non-traditional configurations. Thermasi Furnaces use up to 41 percent less energy than traditional electric furnaces. A fact verified by United Laboratories (UL) through their scientific rigorous processes and testing. This makes Thermasi Furnaces instantly distinct from traditional furnaces.
The common open coil electric heating technology in use today is over 100 years old. Thermasi's 21st. Century technology utilizes thermal mass, control algorithms, special proprietary design features, modularity, scalability, and energy usage monitoring (just to name a few).
For Example: A typical home 2,000 square feet: A conventional electrical furnace will typically require of 80 to 100+ amps of power consumption utilizing a 20 to 25 kw heat kit. A Thermasi furnace would only require 42 to 45 amps of power consumption and achieve the same amount of heat.
Thermasi Furnaces encompass Mass, Infrared Heat, and Special Design Features that are built within the furnace to capture and create more usable heat with less energy!
Mass: Once a mass is heated, it remains heated far longer than traditional open coil heating systems and requires significantly less energy to remain hot.
Infrared Heat: Thermasi furnaces, feature the ability to control the "infrared spectrum" in numerous ways capturing all the heat produced and use it in a more efficient manner.
Special Design Features: The modularity and scalability is possible due to the stack-ability of the heating chambers. One heating chamber is good for up to 1000 square feet. Unlike a conventional electric heating system, Thermasi can stack heating chambers on the return side of the fan. This gives more flexibility than conventional systems. There are a few other considerations to account for when sizing such as geolocation, age of the house or facility, basement height, mechanical footprint, insulation etc. that determines the number of heating chambers required for the home or facility.
Thermasi Furnaces offer customizable efficiency to accommodate any climate and heating requirements for your clients.
Thermasi, LLC has built a rich tradition of innovation, service and exceptional quality in the heating category since our founding. Our focus has always been to partner with our customers to solve the challenges they face in heating their operation and homes with customizable energy efficient equipment.
