How Engineers Use Electric Heat to Create Comfort
Electric heat is the future of heating and cooling, and a key component in achieving the goal of the all-electric building or facility. Whether installed in a home or a high-rise, a heating system is only as good as its building’s coldest room. Comfort is key when it comes to productivity and contentment. Despite the collective groan over the cost of electricity, the push for net zero energy building is forcing its use. Fortunately, HVAC technology is evolving. Engineers developed electrically powered systems that are more effective and provide users with comfortable environments in which to work and play. Being warm, however, is not the only thing that an engineer must consider when using electric heat. Many factors must be evaluated to offer consumers heating and cooling solutions that satisfy their varying needs and, ultimately, provide them with space they can inhabit comfortably. As the move to all electric HVAC gains speed, variable refrigerant flow (VRF) systems are rising in popularity as the best alternative to fossil fuel sourced systems. Engineers use multi VRF system technology to provide consumers with heat that is cleaner, more efficient, and effective. Variable refrigerant flow systems do less damage to the environment than traditional forced-air systems, while offering the same level of comfort—except when the temperature drops.
“Supplemental technology is required to make VRF systems fully functional in all environments.”
Unfortunately, VRF systems failed to be the one-source solution to electric heating and cooling they were promised to be. Supplemental technology is required to make such systems fully functional in all environments. Typical VRF supplements include additional heating units that keep refrigerant flowing when the temperature falls below 20⁰ F. While most supplements are acceptable, most increase cost and loss of energy and heat. Engineers are finding that Radiant Electric Heat’s (REH) infrared electric heat panels are more effective and more efficient as VRF supplement heat pumps—if not full replacements—in the creation of comfortable spaces for consumers. Radiant Electric Heat’s unique CeramiCircuitTM technology guarantees thermal comfort anywhere with any HVAC system. Standard electric heat panels are known for being fragile, expensive, and inefficient, with resistive elements that experience breakage and failure as they expand and contract during heating processes. Typical heat panels produce heat after they have powered on but immediately cool when powered off, requiring constant energy use which increases the cost to maintain a stable temperature in a building. In contrast, REH’s panels with their proprietary element comprised of a carbon steel core, porcelain coating and aluminum oxide resistive trace, allows REH panels to immediately produce heat when turned on and to continue emitting heat while powered down when the thermostat cycles off. This slow release of heat energy from the carbon steel core creates very even temperatures, maximizing efficiency and occupant comfort. Engineers looking to offer consumers consistent heat output are finding REH’s CeramiCircuitTM technology a welcome alternative to traditional electric heat panel technology and other supplemental HVAC equipment. Occupants in buildings with REH panels are warmer quicker and for longer periods of time, enjoying increased comfort while using less energy due to their 52% greater downward radiant output per watt than competing radiant heaters. While VRF systems can deliver heat to most parts of a building, there are some places that it just cannot reach. Engineers can quickly and easily install REH’s panels anywhere they are needed. Installation is available by three different methods: lay-in ceiling, surface or suspended ceiling mount, or wall mounted cove. The sizing of the installed heat load is customized to the requirements of the building—and to accommodate individual occupant comfort.
