Underfloor heating, an idea first used by the ancient Romans, is once again becoming the most popular form of heating in the United States, the UK and throughout Europe from East to West. Because of its superior comfort and efficiency, people are discovering that a radiant underfloor heating system has more advantages than they believed possible.

Underfloor heating gives a constant and extremely comfortable heat, with no blasts of hot air from noisy fans or blowers to stir up dirt and dust. The absence of unsightly radiators makes furniture placement easier and creates a safer home environment with no exposed hot surfaces.

Underfloor heating radiates comfortable, constant warmth with healthy, clean, quiet and safe heat to the occupants and surfaces of the room.

It’s true. When your feet are warm, you feel warmer and more comfortable all over. Because the AHT heating system heats rooms through the floors, the air temperature is always highest at floor level and decreases steadily toward the ceiling. That’s comfort!

The moisture content of the room is more stable and healthy. Unlike forced air heat, radiant heat is less likely to dry out your nasal passages, less likely to dry out the skin, and less likely to cause damage to furniture.

Because the air is not dehumidified, it feels several degrees warmer than it really is. And for every single degree of lower temperature, you save energy and money.

Comfort alone is a good enough reason to invest in an AHT underfloor heating system, but there are other good reasons…like cost-savings and energy efficiency.

With an AHT underfloor heating system, people often discover that they are comfortable at temperatures lower than those provided by conventional systems…and lower temperature settings mean lower electricity costs.

With AHT underfloor heating systems, savings begin with the purchase of the system. Not only do our systems cost less to purchase and install than other radiant underfloor systems, they usually cost less to operate.

Discover the comfort, feel the warmth, and enjoy the efficiency of radiant underfloor heating.

Ask your nearest AHT distributor for a quotation for your next building or renovation project. You’ll be surprised how economical radiant underfloor heating can be.

AHT’s Snow-and-Ice Melting system is ideal for external concrete, asphalt, paving stones, gravel and lawns/turf (sports fields etc). Based on our unique Amorphous Metal Ribbon Technology they have significant advantages over any other type of hydronic or electrical cable-based Snow Melting and Ice Prevention systems.

Benefits are as follows:

• Larger contact area with the cold ground or iced surface
• Reaches the working temperature faster than other systems
• Energy saving
• Less costly
• Generates more even heat
• Extremely simple and easy to install
• Perfectly safe from electrical shock hazards and electromagnetic radiation
• Reliable and durable

AHT currently supplies two product families:

• Outdoor underground heating ribbons or mats normally at 250 – 500 Watts/m2
• Pipes and Gutters Freeze Protection/Heat Tracing ribbon

Both families are based on a unique design of fully grounded heat-tracing cable made of amorphous metallic ribbon enclosed in a mechanically robust flexible enclosure. The element is designed to meet IEEE 515.1 standard for underground and outdoor exposed applications.

The heating element is of a fixed wattage. By using different widths of amorphous ribbons and different length of the element itself, one can achieve the required output power per linear meter/foot. Typically the high-end limit for the heating element power is 62 watts per meter. This limit corresponds to more than 5 amps on a single circuit. The heating element can be driven by various power voltage sources, AC or DC: 110-120, 208, 220-240, 400 and 600 Volts, as long as the current limit is met. Low voltage (below 50 volts) usage is also possible. The upper limit working temperature of the heating element is 70°C.

The heating mats are designed to cover a nominal 20% of the heated area, but the normal area-covering density ranges from 15% to 30%. Other values are also possible.

The normal input power of each heating mat is 250 – 500 watts/m2. as specified on each heating mat label. Higher input can easily be achieved by reducing the spacing between parallel heating elements.
