Our heating systems can be classified into two main categories: radiant heating and high velocity heating. Both types of emitters are heated using boilers. Boilers are sized using heat loss calculations based on the building or space being heated. Denrite’s systems are designed for lasting comfort and efficiency. In some instances, multiple boilers may be required based on the home size, heating requirements, zoning and cascading efficiency gains. The mechanical boiler is the heart to any radiant heat or high velocity heating system.
In-floor radiant heat involves installing piping above insulation on the ground (used to prevent heat loss below the structure). The oxygen barrier pipe is attached to the insulation or to wire mesh or rebar, then 3 to 4" of concrete is poured over the pipes. This is most commonly used in basements and garage slabs, although it has been used with great success on above grade floors.
Overpour radiant heating involves the use of oxygen barrier pipe which is attached to the top of a subfloor with plastic staples. The floor is then topped with 1-1/2" of light weight concrete (gypcrete or agillia). Typically this is not used for retrofits because of the additional weight of the concrete. Even light weight concrete can weigh 12-14 pounds per square foot for a 1-1/2" pour so advanced planning is required for this application.
The Staple-up system is the most common way to add radiant to any structure, new or old. With the staple-up system, aluminum heat emission fins are used to hold the oxygen barrier (Uponor Heliopex) tubing up against the bottom of the sub-floor. A reflective barrier and insulation is then installed below this so that all of the heat goes in the direction that you want which is up into the room above. This method works well for new construction and retrofits.
Quick Trak radiant heating involves the use of strips of ¾” plywood (8” wide) with aluminium backing and oxygen barrier (Uponor Heliopex) piping in between plywood pieces and on the floor’s structure.
Low temperature radiant heating involves the use of a large amount of fin tube (usually copper pipe with aluminium plates placed closely together) using a lower fluid temperature (Typically 95-120°F) to deliver heat to the room. These can be used on the wall or in ceiling.
Baseboard radiant heating involves the use of a large amount of fin tube (usually copper pipe with aluminium plates plates placed closely together) using a high fluid temperature (Typically 160-180°F) to deliver heat to the room. These are to be used low down on the wall. These are typical to apartments and some older homes.
Keep your driveway, sidewalk, stairs and veranda maintenance-free and safe year-round by installing a Hydronic Snow-melting System. Not only does it eliminate plowing, shovelling, and ice, they prevent potential damage to the concrete caused by snow-removal equipment and corrosive de-icers. A sensor in the driveway detects falling snow and sends a signal to the boiler to turn on. Fluid circulates through the tubing to heat the concrete and in turn melts the snow as it falls.
