- Where do you install the slab heating cable?
- <p>You should install the cable 2-3" below the finished surface, and attach it to rebar and/or reinforcing wire mesh to secure the cable in place.</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>
