Snow and Ice Melting

Take Control of Your Time, Budget and Safety at Your Facility

A REHAU hydronic snow and ice melting (SIM) system automatically clears outdoor surfaces beginning with the first sign of snow or ice. With proper design and installation, a REHAU SIM system will provide long-term performance and reliability. You'll save the time, energy and expense of traditional snow removal while improving safety around your facility.

How it Works

A REHAU SIM system clears pathways around the Fallsview Casino Resort in Ontario.

Radiant Heating Applied Outdoors: REHAU hydronic snow and ice melting (SIM) systems circulate warmed fluid (usually glycol and water) through crosslinked (PEX) pipe installed within outdoor surfaces, melting and evaporating snow or ice before it accumulates.

Electronic Controls "Know" the Weather: Controls continually monitor data provided by outdoor sensors and ready the system to begin melting as needed. 

Automatic, Energy Conscious Features: The controls ensure the most efficient use of energy by calculating the precise temperature the fluid must be heated to in order to cause melting. The system automatically shuts off when the surface is dry.

Idle Option Ensures Optimal Safety: When snow is imminent, the system can be programmed to idle. This keeps outdoor surfaces warmer than ambient temperature so the system is ready to melt the instant snow begins. When temperatures become so cold that snowfall is unlikely, the system will turn off to save energy.

Designed to Handle Conditions Specific to Your Area: REHAU has the engineering expertise to help you design a system with output capacity geared to the specific conditions in your geographic area. 


Increases Safety and Reduces Liability Exposure
Snow and ice melting (SIM) systems eliminate snow and ice build-up, increasing the safety of surfaces where people walk and drive. By keeping these areas clear of the frozen elements that can cause accidents, a SIM system also reduces your liability exposure.

Provides Convenience, Control
The automated convenience of a SIM system eliminates the hassle of coordinating snow removal, long hours and the risk of worker injury.

Offers Cost Savings
A well-designed SIM system is often less expensive to operate than hiring motorized snow removal equipment. It also eliminates the damage to surfaces caused by equipment and chemicals as well as the wear and tear from salt and water being tracked inside.

Minimizes Environmental Impact
Carbon emissions from snow removal equipment and runoff contaminated with salt and chemicals directly impact the environment.  By installing a hydronic SIM system, you eliminate these in addition to preserving the life of landscaping, which is often damaged by the weight of snowbanks.

Falls View Casino Resort

Fallsview Casino Resort in Ontario, Canada

This upscale casino and resort is located near the famous Horseshoe Falls, which gives off a mist throughout the year that can result in dangerous ice accumulation during cold weather. To increase safety for visitors walking around the property, the owners installed a REHAU Hydronic Snow and Ice Melting System, featuring RAUPEX O2 Barrier crosslinked polyethylene (PEXa) pipe, underneath outdoor pathways.

Solaris Snow and Ice Melting Project

Solaris Town Center, Vail, CO

Nestled at the foot of the Rocky Mountains is Vail, Colorado’s town center, Solaris. A vastly impressive facility, Solaris boasts 79 condominium units and two stories of retail space, all encircling a community plaza where residents can enjoy a movie theatre, bowling alley and fitness center. With the amount of snow Vail typically receives, a robust, energy-efficient snow and ice melting (SIM) system was crucial. More than 75 miles (120 km) of RAUPEX pipe were used for the radiant heating and SIM systems throughout the complex.

Steamboat Springs Promenade and Plaza, Steamboat Springs, CO

On a late winter afternoon in early 2012, a crowd of 3,000 people gathered at the base of the ski area in Steamboat Springs, Colo., where a 70,000-sq-ft “Promenade” had been completed the previous fall. Few were aware that beneath the pavers and concrete underfoot, a sophisticated array of pipes and manifolds melted snow and ice in real time, making the evening’s activities possible.

Mercedes-Benz Dealership, Burlington, Ontario

When designing and constructing this modern dealership, the owners kept an eye toward sustainability as well as features for customer and employee comfort. Among these are a REHAU snow and ice melting system in the outdoor areas surrounding the building. The system, including a total of 16,000 feet (4,880 m) of 5/8-in. RAUPEX pipe and 7 PRO-BALANCE manifolds, was incorporated into all customer entrances and walkways, as well as the outdoor ramps to the dealership’s 17 service bays.

Police Headquarters, London, Ontario

This important building for law enforcement is able to avoid potential winter hazards with a REHAU Snow and Ice Melting System. The system was installed under the garage entry ramp which features a steep incline that posed a potential hazard during the winter season, particularly for trucks and larger police vehicles entering the garage. RAUPEX® pipe provides extended system life and optimum performance under rugged conditions, resisting conventional solvents and chemicals as well as hydrous salt and acid solutions.

Chenequa Fire Department in Chenequa, WI

This community firehouse faces the challenge of having a hill location and a steep driveway, which posed a hazard when ice would form during Wisconsin’s notoriously cold winter months. Its close proximity to a major intersection was also a safety concern that had to be addressed when the facility was being evaluated for renovations. Ultimately, a REHAU Snow and Ice Melting System was installed in the driveway to cut the risk of trucks and people sliding on the winter ice.
