The “Ancient” Art of Sustainable Living

As a current or future radiant heat consumer, you might fancy yourself to be part of a growing trend towards sustainable home heating. What you may not know is that although it is considered an emerging, “modern” trend among residential homeowners, radiant heat technology is actually thousands of years old.

The history of underfloor heating began in 10,000 BC with the Chinese, who used the word “kang”(original meaning, “to dry”) to describe what became known as a heated bed. Inhabitants drafted smoke from fires through stone covered trenches in the floors of their subterranean dwellings. The hot smoke heated the floor stones, radiating into their living spaces. Evidence of heated floors based on this principle were found in 5,000 B.C. in China and Korea.

The Greeks and Romans finessed the process in 500 B.C. with the hypocaust. Literally translated, hypocaust means “heat from below,” from the Greek word hypo meaning below or underneath, and kaiein, to burn or light a fire. This system was more efficient and less evasive than that of its Asian predecessor. It used pillars to raise the floors, creating a space underneath to circulate hot air. Spaces were left inside of the walls so that hot air and smoke from the furnace would pass through enclosed areas underneath the floor and out of flues in the roof, radiating heat through the walls along the way. While the hypocaust was a marked advancement in under floor heating, the process of heating itself was labor-intensive and high in fuel costs, making it a luxury for those living in villas, and at the public baths.

It wasn’t until the 1980s that standards were developed for underfloor heating systems. Five years later, radiant heat became a traditional system in residential buildings in some European and Nordic countries, and began to find its way into non-residential applications. These modern under floor heating systems use either electric resistance elements (electric) or heated fluid flowing in pipes (hydronic) to heat floors. Both can be cast in concrete, placed under the floor covering, or attached directly to the wood sub floor. Either type can be installed as an alternative to forced air to improve home air quality and reduce heating costs associated with fossil fuels, or as a localized system for thermal comfort.

Electric radiant heat marks a growing trend in residential heating. Electric radiant under floor heating systems are less evasive and less costly to install than hydronic systems, which require skilled designers and tradesmen familiar with boilers, circulators, controls, fluid pressures and temperature for proper installation. Electric radiant heat systems are more efficient than hydronic systems. Powered by electricity, radiant heat cables can heat a surface in 30 to 60 seconds, unlike hydronic systems, which may take anywhere from 4-7 hours to heat a surface—a considerable difference in performance. Because there is a boiler involved, hydronic systems may be fueled by natural gas, oil, coal or wood, making them less environmentally friendly and more costly to operate.

Heating systems for homes and businesses are faced with an increasing number of options to consider for their primary and secondary heating. While fire places and coal burning stoves become less popular, other alternative heating methods are quickly becoming more common. Traditional furnaces as a primary heating system are now being challenged from radiant baseboards, radiant floor heating systems and even radiant ceiling heaters. Many of these new heating systems are using electricity instead of natural gas or heating oil.

Space heaters are also becoming a less expensive option to upgrading a poorly insulated home or to add supplemental heat to cold areas. Thermostone heaters and heated towel warmers from Climastar mount to a wall and are a couple of heating systems that have been commonly used in Europe for decades are now gaining acceptance in the United States. Many interior designers are adopting these electric heating systems as fashionable accessories to bathrooms, basements and home offices.

A common challenge to traditional heating systems is the inability to zone your home for specific areas of the home without heating the entire home. Electric radiant heating systems can be easily designed to be independently controlled by zone which enables a home owner to increase the temperature for defined areas of the home during occupancy and conversely allows a particular zone to remain off during down times. This strategy not only saves the home owner money, it gives you complete control to efficiently warm you most used living spaces without comprising cost.

Choosing the best heating system for a new home or to add supplemental heat to a cold spot in your home now takes a little homework. The radiant consultants and designers at Warmzone have been trained in all of the latest heating systems to properly assess your project and prescribe a system that will add value to your home inside of your budget.

As demands for lower energy costs increase, homebuilders, househunters, and home renovators alike are looking for energy-efficient heating options for houses.  We say they need look no further than radiant heaters for their ideal home heating solution.
In a nutshell, radiant heating is among the most efficient forms of heat available in today’s market. Significantly less operating time is required to attain and maintain the desired warmth compared to furnaces and other, traditional methods of heating, which keeps operational costs to a minimum.

High efficiency boilers or electric radiant floor systems makes radiant heat one of your most efficient ways to heat your home. Combined with a well-insulated home, these radiant heater systems can quickly warm your home and then shut down or wait idle for long periods of time before being called upon by the thermostat to operate.

Radiant Heaters Tip:  Being more environmentally friendly doesn’t have to involve major renovations. Many people waste a lot of energy by not sealing cracks, doors and windows. Checking to make sure a home’s insulation is in good shape and replacing it if it’s not is another good surefire way to stop, prevent, and reverse energy waste.
