While forced-air is essential for ventilation and humidity control, it makes sense to cover more of the building’s sensible heating load with radiant.  Water carries 3,500x more heat energy than air. HVAC designs that use a hybrid radiant and downsized/optimized forced-air system are an excellent way to address high-performance buildings, without sacrificing occupant comfort.  Radiant excels in large commercial spaces, with high ceilings.  Warehouses, hangars, schools, offices and zero energy targeting buildings are great fits for radiant.

Human comfort is a complex topic.  Experts at ASHRAE have developed a building standard focused on human occupancy.  Robert Bean, host of healthyheating.com also has great explanations for how all of the complexities of comfort work together.

Architects love radiant, because you can reduce the HVAC clutter in a space. Architect Frank Lloyd Wright even used radiant in his iconic Fallingwater House.  Radiant heating is often used for floors, but can also be installed in walls and ceilings.

Heat emission from the human body occurs mainly via four mechanisms: radiation, evaporation, conduction and convection. Humans feel most comfortable when they can regulate at least 50% of their heat emission via radiation.

Water pressure regulators or pressure-reducing valves (PRV) are compact valves used to reduce high incoming water pressure from the public water main.

The valve’s robust mechanical strength and ability to resist varying pressure, flow, and weather conditions, ensures a reliable service life. The plastic body and trim are crafted to reduce friction, enhancing durability and efficiency. Furthermore, the valve’s design, featuring a unitised rolling diaphragm and a guided plug, minimises diaphragm distortion and ensures precise regulation.

If a thermostat reads 70°F (21°C), will everyone in the room be comfortable? Probably not. The temperature of the surfaces around you, air speed coming out of your vents, humidity and air temperature are factors that your heating or cooling systems can address. Your clothing and metabolic rate also contribute to your comfort. Together, these are the six primary factors that influence human comfort. With radiant, you can control more human comfort variables. Specifically, you can adjust the actual surface temperatures of the objects in a space by emitting heat through a network of PEX pipes hidden in the floors, ceilings or walls. By changing the temperature of the surfaces around you, less of your comfort depends on the temperature and velocity of the air in a room.

As an example, you feel warm when you stand in direct sunlight, even on a cold day.  While the air temperature may be cold, the warm radiation from the sun feels nice.  With radiant heating, the entire floor of your home can be a warm heat source, radiating heat to warm your skin.  As an added bonus, all of the objects on the floor warm up, so no more ice cold chairs.

Actuated by a pressure-responsive diaphragm, this valve is engineered to balance between hydraulic forces and a preset spring force, ensuring equilibrium is maintained throughout its operation. This dynamic response allows it to adapt to fluctuating demand and varying upstream pressures, securing a steady downstream pressure.

Bermad’s PRV is designed with a singular purpose: to effectively lower incoming water pressure, thereby safeguarding subsequent system components. It includes an integral check valve feature, which guards against pressure drops in the secondary circuit, maintaining a stable system environment.
