Do it for COMFORT By warming your basement, bathroom, or kitchen, you're making your home more comfortable and your tile floors less chilly—ideal for early mornings and long winters.

 

We stock Schluter's Ditra Heat System in our store. Below we'll outline the pro's and con's of the system and offer you a price breakdown of materials and energy costs.

Ditra Heat: All-in-one underlayment & in-floor heat


Ditra Heat is the hot new product from Schluter Systems. 

  • Easy: Simply thinset down the Ditra Heat mats, snap the cables into place, and tile on top. 
  • Quick: Instead of waiting for layers of thinset and self-leveller to dry, you can install your underlayment (Ditra Heat mats), heat system, and tile all in just one day!
  • Lightweight: No heavy cement boards.
  • Thin: Your Ditra Heat mat and wire cables are only an 1/4" thick total, while a traditional 1/4" cementboard + an 1/8" heat cable with 1/4" straps creates a thicker sandwich of materials under your tile that could make your floors much taller than the adjoining carpet or wood floors.
  • Waterproof: Instead of painting on a waterproof coating, adding yet another layer to your floor, simply use Schluter Kerdi Band to cover any seams or cuts for a waterproof underlayment; great for preventing moisture from seeping through the concrete slab in a basement or preventing splashed water or burst pipes in a bathroom from dripping down and causing issues below.

Pros and Cons

Layers of Ditra Heat compared to layers of Cosy Floor

On average, about 10-25% more expensive for materials than other systems (See the Cost Comparison below for a pricing breakdown)

Due to the fact that Ditra Heat is a simple, all-in-one underlayment and heat system kit, it has the Fastest Installation Time of all heat systems we know. What extra you spend on materials is mitigated by time saved (and when hiring a contractor, time is money).

Feet on a warm floor. Both the Ditra Heat and the Cosy Floor are in stock at our Kent location.

Most people only have the heat system on for a few hours in the day, usually just to warm the bathroom floor when getting up in the morning. Consider when and where you want your floors cozy when choosing a heat system. 

NOTE: Prices calculated based on Puget Sound Energy prices as of 9/10/2014. These are rough estimations for the purpose of assessing the long-term cost of a heat system and are not a guarantee of your actual bill. Wire spacing, size of the heat system, total electrical usage of the household, and other variables will affect the per square foot cost of the kit.

Building Codes and Dedicated Circuits


Check your local building codes to see if there are any rules or regulations pertaining to in-floor heat systems before you purchase or install one. Sometimes an inspection by an electrician is required by law, while sometimes it's optional. 

 

Also consider what is required for your kit's warranty. Does it require an inspection by an electrician, or could you simply do the test yourself with an Ohm's Meter to qualify for the warranty? 

If you choose to hire an electrician, we recommend SCG Electric:

Electrician for Western Washington

SCG Electric
Scott Glassmeyer
Des Moines
206-948-6464
206-824-2656


You may need to run a dedicated circuit for your new installation. You can consult an electrician to ensure that your new heated floor will be installed correctly.

Do you need a thermal break?


Cosy Board Thermal Break - for your home in Bellevue, Redmond, Seattle, Tukwila, Renton

A thermal break is an insulating layer that keeps your heat where you want it. A thermal break layer under your in-floor heat system will bounce the heat back up into the room, so very little heat escapes into the space under the floor.

Pros

More energy (and money) is saved as you're not losing a lot of heat into the space below your floor.

Cons

A thermal break layer will usually add between 1/4" and 3/4" to your floor, potentially making it too tall to meet up to adjacent floors without a sloping ramp or transition piece. 


Recommended for:

Basements or ground floor rooms on a concrete slab. The thermal layer will prevent the slab from absorbing heat from your heated floor system.

New construction where you have control over the height of all floor types and can make them all even. 

Not Recommended for:

Second-story bathroom floors that are above a heated room.

Spaces where the extra height is an issue. 


Thermal Break Options

The Ditra Heat TB integrates a thermal break into the underside of the mat for the thinnest heat system + thermal break combination yet.

 

Nominal 5/16” (8mm) thickness.
