There are two main systems of classification: old ASHRAE and new ASHRAE. This enables the customer and to select the appropriate performance level using the snow- free area Ratio

This is the second unit I’ve installed as the first one, installed two winters ago in another building is working so well. No problems, easy to install. Both systems are hydronic floor heat and these units work great. Just fyi…….going to electric now works out cheaper than the original propane costs. Like that it’s Canadian made.

Drainage is a very important aspect when designing a Snow and Ice Melting System. Just as rain, melted snow must have a good drainage path. Adequate slope must be provided for natural drainage. There must be control run-off so as not to create hazards. Also, in order to make sure that drain is not freeze pipe should be installed under and around the drain. Drain need to be connected to available storm sewer system as per the code requirements.

I bought these to replace some wax actuators from my old system. Those were inconsistent (each moved a different amount) and had huge in rush power requirements. These have low power requirements and appear to be very consistent.

To avoid excessive temperature and pressure drop. The Pex tubing is divided into circuits, each having one supply and return to and from the manifold. to avoid the hassle of balancing the flow, it a good to keep all the circuit the same length. The table below show the maximum circuit length for specific pipe diameter:

• Ar = 1.0 Snow-Free Area of 100% - No accumulation during snowfall• Ar = 0.5 Snow-Free Area of 50% - Some accumulation during snowfall• Ar = 0.0 Snow-Free Area of 0% - Surface may be covered with snow during heavy snowfall, melting snow from the bottom of the layer.

Freeze protection – the use of a freeze protection is essential in a snow and ice melting system. We recommended the use a mix proportion of glycol to water of 50/50.

When considering such a system, the two main limitations are the cost and lack of proper design information. These two goes hand in hand. Just as any system need to be design accordingly so does a snow and ice melting system. The big hurdle as previously mention is both the installation cost and operation cost. Regarding the installing cost will indeed will be most of the time the market price. but when it come to the operating cost the answers depend on lots of variables such as:

ASHRAE has develop most of the standard pertaining to energy requirement of Snow and Ice Melting systems. These are based on a number of variables such as geographical location, rate of snow fall, air temperature, humidity, wind speed and system performance expectations.

• Output ranges of approximately 125 BTUs to 175 BTUs per square foot• During heavy snowfall, some accumulation may occur• 25%-50% cover

1 The sub-grade layer of a pavement is, essentially, the underlying ground. It is also known as the "Formation Level", which can be defined as the level at which excavation ceases and construction starts

Controlling a Snow Melting and Ice system properly is critical to performance. Controlling the system is a good way forward to minimize energy waste. These systems work proactively better than they work reactively.

Based on Information available from The National Research Council of Canada. The table below give the suggested output in BTU per square foot.

At Nordik Radiant, we specialize in hydronic heating. Based in the heart of Canada, in a climate where winter presents its challenges, we have developed particular expertise in an essential area: snow and ice melting. In this article, we will delve into the issues, solutions, and benefits of snow and ice melting in detail, highlighting our accumulated expertise in this specific field over the years.

If a Snow and Ice Melting system is properly design, the efficiency the system will be very efficient. Design is definitely an essential aspect to consider when choosing to implement a Snow and Ice Melting system in any project.

Prior the installation of any tubing, the formation level1 need to be properly compacted to avoid mainly settlement and rutting under the structure. As per ASTM standard, the compaction rate should be as follows: 96 to 98% for soil, and around 101 to 103% for a compactable soil/sand base2

As recognized experts in the field of snow melting, Nordik Radiant is your go-to source in Canada for reliable and effective solutions. Our online store offers a comprehensive line of quality products designed to meet the specific needs of snow and ice melting in various climatic conditions. You can make your purchases with confidence, knowing that we only offer proven and high-performing products.

Once the underlying ground is compacted, insulation is put in placed to improve the efficiency of the system. Insulation is added both under the slab and to all exposed edges in this way reducing the heat loss into the ground and at the same time allowing the slab to heat at a greater rate which in turn lower the total operating costs.

Usually, most insulation is done with rigid polystyrene foam 1 to 2 inches thick. But my recommendation is to check with is your concrete specialist and they will be able to guide you if insulation is allowed by code or in your application (e.g., load-bearing cars), and what type and thickness to use.

Selecting the right size pump that has the capacity to equal to the system flow rate and a head equal to the system pressure loss is essential. Pump selection will be covered in our next blog.

Snow and ice Melting System is a great alternative though expensive but it relieves lots of the pain that come with the winter chores such as• Snow Blowing• Shoveling• Salting

You are tired of shoveling or snow blowing on the cold winter morning just before working because your car is trapped with snow.

Snowmelting systems for concrete slabs

The Pex tubing is secured on wired mesh or rebar over the compacted grade with wire mesh or tie wraps at every 3 feet along a straight run. Where the Pex pipe make the 180-degree turn, there is 3 points of attach (on the top of the arc and 1 on each side of the arc). In such a way this prevent the Pex tube from floating or moving during the pour. For minimum concrete covering for the Pex pipe please refer your local building codes. (Usually, a minimum of 1½ inches of concrete)

Several manufacturers offer ‘’smart “control which are tie into National Weather service or Environment Canada to predict incoming snow and activate the system before the first snow falls. Different type of sensor may be used to detect temperature change or moisture variation. We proposed on our online store these sensor.

In conclusion, the importance of using a snowmelt system lies in its ability to enhance safety, protect property infrastructure, and reduce the time, effort, and environmental impact of snow removal. While the initial investment may be significant, the long-term benefits in terms of safety, property maintenance, and environmental stewardship make it a worthwhile consideration for property owners in regions prone to snow and ice accumulation.

Snow and Ice Melting system can be installed in a variety of construction methods such as concrete slab, steps, paving or asphalt.

Once the output in BTU per square foot is determined using the information above the heat source can be chosen. There are many different options that can be used for the heat source.

Another advantage of a Snow and Ice Melting System is that it increases the longevity of your finished surfaces such as concrete, paving or asphalt.

To determine the number of BTUs per square foot needed to meet the selected class for the geographical location in Canada is somewhat limited. there are agencies that provide relevant information for design condition such as the National Research Council Canada through the Institute for Research in Construction.

I purchased this glycol pump as part of the build your own, which included the manifolds pump, expansion tank, air separator and basic plumbing supplies. I was very happy with how everything arrived together and the install was straightforward just from looking at the pictures. The glycol pump makes it easy to charge the system, and took a lot of the guesswork out of setting it up. My garage now has toasty warm floors.

The tubing layout for SIM system is different from a radiant floor heating application. Usually in a typical radiant floor application the tube is installed in such a way the supply (warmest fluid) is directed first to the area where there is the greatest heat loss which happen to be in most cases the exterior wall. Whereas as in a SIM system to manage to have an equal heat distribution across the surface, the counter flow pattern (reverse Return) is highly recommended.
