The time needed to warm up your floor depends on several factors, such as the heat loss, your local weather or season, the type of subfloor you have, the space & insulation under the heated floor, and the watts option you chose (10 or 15 watt/ sq. ft.). In most cases, a second floor bathroom with 15-watt/ sq. ft. product will reach 78-to-82 deg after 30 to 40 minutes (which is most people's preferred temperature) and 90 deg after 2 hours. Installations with 10 watt products have a slower build of heat.

Is there any Fire Hazard?

No, there is no risk. As a matter of fact, our product is UL certified. UL (Underwriters Laboratory) tests electrical components and equipment for potential hazards. When something is UL-listed, that means that the UL has tested the device, and it meets their requirements for safety - i.e.: fire or shock hazard.

 Installation

The WarmlyYours new ultra-thin electric systems are designed to be installed on top of the sub floor and directly beneath the stone floor covering during the final application. The mesh backing allows the system to be quickly laid out and affixed to the sub floor by the floor covering professional immediately prior to floor covering application.  There is no need for a radiant heating specialist, and most installations can be completed by the first time floor covering installer or HVAC professional without prior training, thanks to our installation guides and 24/7 technical support line.

 How do I get started?

You can send us a floor plan for a free customized installation plan and a precise estimate.  Simply fax or email us a floor plan and we’ll have our design team take a look at your room and work out exactly how we can fit our product in there. Make sure that you mark on what kind of floor you’re looking to heat, and we’ll prepare a customized installation plan that will show you the coverage that we can achieve, the way you need to lay out the mat and the full electrical specs for the project…as well as the price.

If the surface you would like to warm is simple, you can call us toll free to get an estimate on the phone.

Who installs WarmlyYours?

There are two parts in any WarmlyYours installation: the installation in the floor and the electrical connection. Obviously the electrical connection should always be done by an experienced electrician.

The open question is really Who Installs WarmlyYours in the Floor? Generally it is the tile setter or the flooring installer. A tile setter can easily cut the rolls and fit the room. The only small electrical experience he needs is to read the ohm resistance with a ohm meter. (see section 7 of the installation manual on the web site)

What should I tell my electrician?

A designated line is strongly recommended to reduce the risk of sporadic or nuisance tripping in the GFCI. Based on the square footage, a 220 line, or 120 line with a relay contactor (installations over 120 Square feet) will be needed. The thermostat works best situated in a double gang box with a single mud ring, giving enough room for the lead wires and sensor wire if the LineVoltPRO is being used. Again based on the square footage and voltage of the system we can determine the size of the breaker on the box, most systems would require a 15 amp breaker. Two conduits are brought to the floor from the control unit, one houses the sensor wire and the other will house the leads. The sensor and the leads cannot share the same conduit.

How do I lay out the rolls on the floor?

The easiest thing to do is to fax us your floor plan and we will fax back an installation layout that is customized to your open floor space with a price quotation FREE of charge.

Repair

Is the product repairable?

Yes, the location of a break or an electrical short can be found. Our success rate at repairing the WarmlyYours system, if damaged during installation, is extremely high. In locating a break we send out a device, ShortStop, which transmits a radio signal down the wire. If our floor plan has been followed, the position of the break or short should not be to difficult to establish. A couple of tiles will need to be removed and the broken cable will need splicing. A repair Free splice kit is available to perform this reparation.

Surface to cover

What floor area should I cover?

If the WarmlyYours roll is installed as a secondary source of heat, we recommend covering only the standing and traffic areas. We like to heat the toe-kick space under your counters and vanities, but we generally do not cover the last 6-to-18 inches against a wall where no one will be walking or standing.

What are the different control options?

The lower end controller options we have are a Comfort Regulator and a Programmable timer. The latter controller offers 7-day, 14 event programming capabilities at a value price (does not regulate temperature) Our Comfort regulator features a convenient dial to control your preferred comfort level with ease.

Our top of the line model is a fully programmable thermostat with a built in Ground Fault Circuit Interrupter. This thermostat features a temperature probe that senses the temperature of your floor. It provides homeowners with total control over their floor heating system. Along with a 7-day, 4 events per day settings, the thermostat is designed for maximum comfort and system enjoyment. We recommend that this product be used with all hardwood and floating wood floor heating capabilities where a floor covering manufacturer has specified a maximum heating level.

How does "Electric" Floor Heating Compare to "Hydronic" Radiant Floors?

"Hydronic" systems use a boiler to heat up hot water and a pump to circulate the hot water in plastic pipes installed in a concrete slab. "Electric" systems use an electric resistance cable, sometimes assembled into a mat or a roll (conceptually similar to an electric blanket) to heat up a thin layer of concrete in the floor structure.
1. One difference is the floor elevation involved. The hydronic system elevates the floor by a couple of inches, which can be a problem in many remodeling jobs. Thin electric systems will elevate the floor by only 1/8".
2. Time to heat up: Hydronic systems are placed 1.5" or 2" into a concrete slab. This is so deep into the floor that it usually takes 4 to 7 hours to heat up when they are first turned ON. Therefore, they are left ON for many months and consume energy during a longer period of time.
3. Energy Saving: The thin electric mats are placed above the sub-floor, just under the flooring material. They will heat the floor in 30 to 60 minutes under tile. They are controlled by a timer and a thermostat and in most cases, the homeowners will preset ON-OFF cycles to provide heat only WHEN he/she needs it and WHERE he/she needs it (selecting rooms and heating from your feet up).
4. Cost of Installation: In remodeling jobs or in select rooms of a new construction hydronic systems will cost more to install. In very large jobs (complete home in new constructions), the hydronic systems will often be less expensive to install.
5. Maintenance and repairs: Hydronic systems need to circulate water continuously and they use valves and manifolds, which are prone to sedimentation, mechanical problems and maintenance issues. Electric systems have no moving parts and require no maintenance. If a hydronic installation is faulty, it is difficult to find a leak and the system is difficult to repair. With electric systems an underground fault detector can find the exact location of the break and after breaking just one or two tiles it is easier to splice the electric cable and replace the few tiles removed.
6. Operating costs: The cost of electricity in America varies between 3 cents/kWh up to 18 cents per kWh, therefore, the cost of generating 1,000 BTU with a hydronic system may sometimes be lower than the cost of generating 1,000 BTU with an electric system. However, the real comparison needs to consider the different ways these two systems are used. The hydronic system will be ON for many months, while the electric system will be ON-&-OFF several times a day according to the ON-OFF settings of each room thermostat. Moreover, during each ON period, the electric system will only use electricity continuously for the initial period of temperature build-up. Thereafter, it will cycle between ON and OFF and will only draw electricity during 25% to 33% of the time remaining during the ON period.
