7. ULTRA FIN Radiant Floor Heating System kk INSTALLATION GUIDE amp k k k Welcome to Ultra Fin Ultra Fin is the leader in cost efficient and high comfort radiant floor heating Ultra Fin is a hydronic system designed specifically for wood frame housing that is simple to install and is compatible with all floor coverings including carpet tile slate and hardwood How Ultra Fin Works The Ultra fin system uses tubing to circulate hot water through the under floor joist Soaces where heat is conducted to louvered aluminum Ultra Fins attached to the tubing The Ultra Fins radiate the heat and warm the air in the joist spaces creating hot air convection The heated air warms the floor uniformly and the floor radiates gentle heat throughout the living space above FLOOR SURFACE WARM AIR WARM AIR CONVECTION ae CURRENTS CONVECTION CURRENTS f E AN q re COOL AIR COOL AIR The science behind the Ultra Fin system What Makes Ultra Fin Different Traditional radiant floor systems are based on heat contact transfer technology where hot water tubing makes direct contact with floor layers Compared to Ultra Fin these systems are overly complicated time consuming to install provide lethargic heat response and require complicated construction measures such as extra floor layers or concrete Ultra Fin creates new efficiency by generating hot air convection
8. for each zone NOTE Ultra Fin highly recommends having separate heating zones tubing circuits for each room in the house C Measure the Joist Spacing The joist spacing in the floor system will usually be 12 16 or 19 In rare instances it could be 24 When you have determined the joist spacing you are ready to calculate the tubing spacing for each zone Heat Loss and Material Calculation When installing an Ultra Fin system you need an installation layout that fits the home and the surrounding climate Use Ultra Fin s Ultra Calc software to calculate the BTU s and materials required for your installation You need the following information e The type of heat source your system will use e g boiler heat pump etc e The anticipated operating temperature of your heat source e The average mean temperature for your area or location referred to as design temperature in the Ultra Calc program click the DESIGN TEMP tab e The length and width of each room in the home e The ceiling heights of each room e The size and R factor of every window and whether or not they are single or double paned e The R factor of the insulation in the walls and ceilings or at least the insulation type and thickness Enter these numbers into the Ultra Calc program on your computer Ultra Calc will tell you e Tubing and Ultra Fin material and spacing requirements e BTU requirements for the boiler not water source
