Frequent Asked Questions
- What wood laminates are compatible with Environ™ Heating System?
- <p>Verify that your laminate is warranted for use with radiant heat. Most modern wood laminate floors are compatible with Environ™ Flex Rolls, but the maximum thickness of the timber / laminate / wooden flooring should not exceed 5/8” (15mm). Flooring that has metallic strips as part of its locking system is NOT compatible, as these metallic strips may damage the Environ™ Flex Rolls. Also laminates that have their pad already attached to the laminate are not compatible with the Environ™ Flex Rolls.</p>
- What underlayments are compatible with Environ Heating System?
- <p>Any type of underlayment/padding may be used as long as it has a density of 6-8 pounds per cubic foot. Certain underlayment, such as ¼” (6mm) thick cork, or 5mm CeraZorb are recommended for Environ™ Flex Rolls. It is also acceptable to place a vapor barrier, such as a plastic sheet, under the underlayment. Underlayment papers are not compatible with Environ™ Flex Rolls. Underlayment is necessary to prevent Environ™ Flex Rolls from damage from the weight of the floor, furniture, and people. Unavoidable wooden floor movements will not harm Environ™ Flex Rolls. Wooden floors expand and contract with temperature and moisture change. The wooden floor “moves” on top of Environ™ Flex Rolls. This movement will not damage Environ™ Flex Rolls when the installation is done correctly and the underside of the final floor covering is installed evenly. Some underlayment materials also have a noise reducing and insulating effect. When installing over concrete, a ¼” underlayment is mandatory. Any underlayment available in ¼” size is acceptable in most cases. CeraZorb, cork, or ¼” to 3/8” of expanded polystyrene (EPS) with a density of 2 pounds per cubic foot or more, are recommended for installation under Environ™ Flex Rolls. When installing over a concrete slab, choose the underlayment with the highest R-Value.</p>
- What is the warranty for the Environ™ floor heating system?
- <p>Environ™ Floor Heating Systems are backed by WarmlyYours 5 and 10 year “No Nonsense™ Warranty* and WarmlyYours highly recognized lifetime 24/7 technical support. Due to the fact that we will also cover not only the cost of labor, but also the cost of the floor itself, our warranty is renowned for being an industry best. Our “No Nonsense™ Warranty” for Environ covers 5 years for under carpet applications and 10 years for under laminate or floating wood floors.</p>
- I have multiple Environ™ flex rolls, how do I connect them to the thermostat?
- <p>Multiple Environ™ products may be connected in parallel directly to a thermostat or through the junction box. Please ensure the total amperage of all connected mats doesn’t exceed the thermostat’s maximum load.</p>
- I have a pre-attached underlayment on my laminate flooring, can I use Environ™?
- <p>No. Laminates that have their pad already attached to the laminate are not compatible with the Environ™ Products.</p>
- What is the typical operating cost of the Environ™ floor heating system?
- <p>The actual cost of operating your floor heating system will vary depending upon a number of factors including the cost of electricity in your area and the length of time you run your system. Try our <a href="https://www.warmlyyours.com/tools/cost-calculators">Operating Cost Calculator</a> for a quick estimate.</p>
- How many watts per square foot does Environ™ deliver?
- <p>The Environ™ Flex Rolls and Easy Mats are designed to deliver 12 watts per square foot.</p>
- Is the Environ™ floor heating system installed directly up to the wall end to end? Can I have it installed under my couch too?
- <p>For carpet applications, we require 12" around the perimeter of the room so that a carpet stretcher can be used without damaging the Environ roll or mat. With laminate floors, you can install it wall to wall. We do not recommend heating under heavy pieces (100lb/ft2). And, never heat under permanent fixtures.</p>
- Will this burn the laminate or carpet?
- <p>No, as long as a licensed electrician properly installs it. We suggest setting your <a href="https://www.warmlyyours.com/thermostats">nSpiration Series</a> thermostat control at a maximum of 85°F when the system is installed under laminate flooring. See your laminate manufacturer for their requirements regarding their product when used with electric radiant heat.</p>
- Is there a visual height difference between carpets with Environ™ underneath and without? Will it make a crunching sound under my feet?
- <p>The height difference and sound is purely dependent on the choice of carpet and padding. Different carpets and carpet pads have different qualities and will be a determining part of height and sound.</p>
- How thick are the roll/mat and electrical cord?
- <p>The roll and mat is 1/16" thick, and the cord is 1/4" in diameter.</p>
- Do I need insulation when installing a floor heating system over a concrete slab?
- <p>When WarmlyYours floor heating systems are being installed on a concrete slab, we strongly recommend adding a layer of insulation over the slab prior to installing the system. While our systems provide up to 25% more heating power per square foot than many of our competitors, the slab will always act as a "heat sink." Some of the heat that would otherwise be transferred to the flooring surface will remain in the slab, causing the floor’s surface temperature to be considerably lower. This is true with any floor warming system.</p> <p>When installed on top of a concrete slab without insulation, it is generally accepted that a radiant floor heating system will take the chill away from the floor and provide a small amount of warmth. Adding insulation on top of the slab and beneath any floor heating system will allow a greater percentage of the heat generated to transfer to the flooring surface. This results in greater efficiency and therefore faster warm up times, higher expected surface temperatures and lower energy usage. The floor will have the capacity to warm to a comfortable temperature, and in some cases can be employed as the primary heat source for that room.</p> <p>The recommended types of insulation are natural cork, insulated tile backer boards and insulated underlayment, such as CeraZorb synthetic cork.</p>
- What voltage does WarmlyYours floor heating systems utilize?
- <p>The floor heating systems are offered in both 120 volt and 240 volt for the North American market. A 208 volt breaker panel can also accommodate our 240 volt floor heating system. It is important to note that the energy consumption will be the same: a 240 volt system will not cost more to operate than a 120 volt system. You are billed in kilowatts, and the 120 volt and 240 volt systems use the same amount of kilowatts. WarmlyYours often specifies a 120 volt system in smaller projects while a 240 volt system is typically recommended for larger projects (120 square feet of electric floor heating coverage or more). The benefit of switching to a 240 volt system is the reduction in amperage. Our programmable thermostat can control a radiant floor system up to 15 amps. The 120 volt system will reach 15 amps at 120 square feet of electric floor heating coverage. However, the 240 volt system will reach 15 amps at 240 square feet of electric floor heating coverage, allowing a much larger system to be connected to the thermostat. For installations over 240 square feet, a relay contactor or power modules are needed.</p>
- How do I work with my electrician to install WarmlyYours electric floor heating?
- <p>While WarmlyYours systems are typically installed by your floor covering contractor, a licensed electrician is recommended for the final thermostat hook-up. With every quote, we provide an Installation Plan layout, together with an electrical plan that has all the info required for the electrician.</p>
- What type of flooring can I install along with an electric floor heating system?
- <p>WarmlyYours’ TempZone™ product is most commonly installed under tile, stone, and marble flooring, but can also be installed under many other popular floor covering options such as hardwood, vinyl and linoleum. We also have our Environ system, which is an electric floor heating product as well and is specially designed for installation under carpet (in the U.S. only), laminate and floating wood. WarmlyYours can accommodate any flooring type with either of the floor heating products that we offer. If your flooring type isn't listed here, just give us a call at (800) 875-5285 and we will be happy to discuss it with you.</p>
- What temperature will my heated floor reach?
- <p>The temperature of your floor can range anywhere between 75°F to 95°F. The floor's actual temperature will depend on a number of factors including the amount of heat loss that the room experiences as well as the room’s configuration. For instance, the warmth contained in a two story entry way would likely be less than that of a smaller, more enclosed area such as a bathroom. In a bathroom that is located on the second floor of your home or over another floor in your home that is typically heated, the temperature of your heated floor should easily reach a comfortable temperature of 85 degrees Fahrenheit, if installed correctly. For the heat loss calculation for your specific room, you can access the <a href="https://www.warmlyyours.com/tools/heatloss-calculator">Heat Loss Calculator</a> or you can call us at (800) 875-5285 and a Customer Service Representative will make the calculation for you.</p>
- What is the total power/amperage that the floor heating system draws? Does this system need a dedicated circuit?
- <p>The amount of amperage draw depends upon how large the area is that you are heating. For coverage of areas less than 30 square feet, the system will draw less than 3 or 4 amps. If you have a larger area over 120 square feet of heated space, then you may need a larger breaker plus additional controls. No matter what the size of the area you choose to heat, we recommend a dedicated circuit for your system.</p>
- I have extra cold lead wire. Can I trim off what I don't need for my installation?
- <p>Yes. Unlike the heating cable, the cold lead wires can be trimmed or lengthened with <a href="https://www.warmlyyours.com/products/by_sku?sku=COLDLEAD">additional lead wire</a> which can be purchased from WarmlyYours.</p>
- How will radiant floor heating affect my wood floor?
- <p>WarmlyYours nSpiration controls are equipped with an in-floor sensor to precisely control the floor's temperature to comply with the wood manufacturer's temperature recommendation.</p>
- How do I know if I am installing my floor heating system properly?
- <p>Please keep in mind that you must check your system with a Digital Ohms meter in conjunction with a <a href="https://www.warmlyyours.com/products/by_sku?sku=SS-01">Circuit Check™</a>. Take an initial reading as soon as you take the product out of the box to verify that it is within -5% / +10% of the values stated on the product’s label. This will give you a basis of comparison for future readings. Take a second reading once you have positioned the system to match your custom installation plan. It is also advisable to take an additional reading in the middle of the tile installation, just to make sure that the Circuit Check™ is doing its job. Then, take a final reading when you are finished with the floor installation and are ready to hook up the thermostat.</p> <p>The <a href="https://www.warmlyyours.com/products/by_sku?sku=SS-01">Circuit Check™</a> is a tool developed by WarmlyYours to give you peace of mind and ensure trouble-free installations. Simply hook up the cold leads to the tool while you position the system to match your custom installation plan.</p> <p>The Circuit Check™ will continuously monitor the continuity of the circuit during the installation of your system and during the installation of your flooring. The Circuit Check™ beeps immediately when a short in the system is detected, alerting you to a potentially damaged cable in the area you are working, before you lay the tile over the floor heating system. The WarmlyYours technical support team is available 24/7 to provide assistance if the alarm sounds, or if you would have any questions during your installation.</p>
