Introducing GreenRadiant, an in-wall, radiant heating and cooling system that is supplied by solar and/or geothermal energy

GreenRadiant Hydronic Heating & Cooling

Rik Global has developed a revolutionary in-wall hydronic radiant heating and cooling system that compliments our HyBlock wall system, enhances its value and together offer a comprehensive climate control solution that has state of the art performance.

A Better Idea

Creates a healthier and more comfortable environment that is more energy efficient and less costly to install.

Thinking Outside the Box

This efficient system replaces conventional: In-floor heating, radiators & other HVAC systems.

Radiant Heating

Tubes in the walls distribute heat to the rooms as well as to the thermo-mass of the walls, where it is then redistributed as radiant heat at night.

The walls radiate heat towards each other, creating a balanced and efficiently heated environment.

The body is exposed to the wall in greater capacity radiant heat affects the whole body at once vs. from the feet up.

Radiant Cooling

During the summer, rooms transfer their heat to the cool water flowing through the hydronic tubing.

The water then flows to the heat-exchange tubing embedded in the concrete foundation where the heat is absorbed and returns cool agian.

Compatibility

Our system works with any hot or cold water source (boilers, on-demand hot water heaters, hot water solar collectors, heat-pumps, chillers or alternative heat-exchange systems).

Magic Formula

The tubes are attached directly to the wall surface.

They are then embedded in 3/4" of clay plaster.

The clay and the wall acts as a homeostatic mechanism for modulating humidity and preventing condensation.

Benefits/Costs

Due to the high heat capacity and density of water, thermal energy can be transported in water in pipes with little pump power, saving approximately 70 to 80% of fan power normally used to condition a building. This alone reduces the peak-power of the air-conditioning system by about 30 to 45%. There is no space conditioning equipment necessary on exterior walls, and the panel system can use the automatic sprinkler system piping in some multifamily dwellings. Radiant cooling panels with minimum fresh air supply is a draft free system that also eliminates fan-coil and induction unit noise. Cooling is more evenly distributed, and drafts can be eliminated. There is less exfiltration of cooled air when doors or windows are opened.

Limitations

With professionally configured and installed units the system can be used in any climate, however because of the risk of condensation in very humid areas proper design and installation may be even more critical. These systems are most economical in areas like Arizona where the humidity is less than 15%. A forced air system, such as an air handler or dedicated fresh air system, may need to be incorporated to remove humidity and pollen. Some systems have a relatively slow system response. Once room surfaces reach a desired temperature, however, they tend to maintain that temperature with relatively little extra energy.

Code/Regulatory

A new and seldom-used technology, radiant cooling is not regulated in the codes like radiant heating.

Availability

Since radiant cooling systems are constructed of components from the radiant heating and air conditioning industries, components are widely available, but engineers experienced in residential radiant cooling design are not.
