COSY FLOOR FAQs

Where can CosyFloor be Installed?

Can I install CosyFloor in the shower or other “wet” areas?

Absolutely! CosyFloor is designed with your lifestyle in mind and is fully “wet installation” approved, allowing you to enjoy the luxurious warmth even in your shower or other damp spaces.

For ultimate peace of mind and long-term durability, we recommend installing a dedicated CosyFloor cable specifically for your wet areas. This strategic approach isn’t about code requirements for separate thermostats, but rather a best practice that many in-floor heating systems recommend for several reasons:

Protection Against Future Maintenance: While CosyFloor is robust, any future work involving waterproofing, shower liner repairs, or tile replacement in wet areas could inadvertently impact a heating cable. Having a separate cable means that if any such maintenance is ever needed, the rest of your CosyFloor system remains completely undisturbed and fully functional.

Targeted Troubleshooting: In the unlikely event of an issue, a separate cable for the wet area allows for much easier and more targeted troubleshooting, minimizing disruption to your entire heated floor.

Enhanced Longevity: This approach helps ensure the longevity of your entire heating system by isolating the most vulnerable areas from potential future disturbances.

What kind of flooring can be installed over CosyFloor?

Tile? Yes

Laminate? Yes. Cables must be installed in thinset or self-leveller.

Engineered Hardwood? Yes, just double check that the floor is rated for in-floor heating by the manufacturer. Do not use nail-down installtion. Cables must be installed in thinset or self-leveller.

Hardwood? No

Vinyl? Yes, providing manufacturer approves installation over heat. Cables must be installed in thinset or self-leveller.

I want in-floor heating in a bathroom with a freestanding tub. Will CosyFloor work for this?

Yep! You have a couple of excellent options for integrating CosyFloor around your freestanding tub, depending on your tub’s design:

Continuous Warmth Under Footed Tubs: If your freestanding tub has feet, you can extend the CosyFloor heating right underneath the tub itself. This ensures a beautifully consistent warmth throughout the entire bathroom floor, leaving no cold spots.

Seamless Warmth Up to the Edge: For tubs without feet, or if you simply prefer, you can install CosyFloor right up to the edge of the tub. This still provides incredible comfort exactly where you need it most.

Installation Tip: When planning the placement of your CosyFloor system, be mindful of any freestanding tub fillers that require drilling into the floor. We recommend maintaining a minimum 6-inch clearance around the exact point where the tub filler will be installed to ensure the safety and integrity of your CosyFloor cable. A little planning ensures perfect warmth and peace of mind!

Can I run the infloor heating under the total floorspace of a kitchen or bathroom?

No. The heating should not be installed under any fixed objects, such as under flat bottomed baths, vanity units, or kitchen cabinets.

Are there any other restrictions I should consider when laying Cosyfloor infloor heating in bathrooms?

Yes, make sure that the yellow heating cable is positioned at least 6in (15cm) from any toilet wax rings.

Installation Questions about CosyFloor

I have too much CosyFloor cable left, can I cut it?

No, if yellow heating cable is cut, the whole system will be inoperable. Moving the spacing closer together – you can install our Cosyfloor cable down to 2 inches apart.

The standard installation recommends 3″ spacing for runs of heating cable, but also says 2″ or 4″ is fine. Why?

If your space is well-insulated and/or has lower heat loss, 4″ spacing may be sufficient. For example hallways or interior rooms with no exterior walls may not require as much heat output.

If your space is in a high heat loss area such as rooms with exterior walls, large windows, or uninsulated concrete labs below, 2″ spacing will provide more heat per squarefoot.

2″ spacing also allows your CosyFloor system to act as a primary heat source not just supplemental warmth.

2″ spacing will result in the floor warming up more quickly, which can be preferrable in for your clients who want to be able to turn on and enjoy their floor heat for (more) immediate use.

How should the Thermostat floor sensor be installed?

The Thermostat floor sensor should be installed positioned between the two yellow heating cables, roughly perpendicular to them. It is not necessary to physically bend the sensor, but it must be placed so that it sits evenly spaced between the cables for the most accurate temperature reading. This means the sensor may appear at a 90-degree angle relative to the floor surface, ensuring it is properly aligned between the heating cables and not touching either one directly. Three studs in the installation area help guide this positioning.

How do I work out how much infloor heating I need?

We recommend leaving a buffer of 4in away from the walls, so work out your measurements using this as your guide. It’s important to measure carefully because if the heating cable or mat is too large it is not possible to cut off any excess – you will have to reorder.

How can I make sure there are no cold spots on the floor?

We recommend a 3in spacing between cable runs. This ensures an even distribution of heat throughout the entire floor area.

How much length do I need to allow for the cold lead on the Cosyfloor mat or cable?

The cold lead at the end of the heatmat or heating cable is 10ft (3m) long.

Is there anything else I need to know before installing CosyFloor infloor heating?

Yes, there are four important points:
1. Make sure the yellow heating cables NEVER touch.
2. Ensure you attach your circuit fault detector during floor installation as well as doing electrical resistance tests to the heating cable before, during and after installation.
3. Ensure the infloor heating cable or mat is completely embedded in thinset.
4. Don’t forget to install your thermostat heat sensor prior to covering your heating mat or cables in thinset.

How does CosyFloor’s Warranty work?

Do you test the CosyFloor systems before you send them out?

Yes, every CosyFloor heating cable is factory tested to ensure it’s safe and installation-ready before shipping.

Do I Need to Send in the CosyFloor Warranty Form?

Yes, you must send in the CosyFloor Warranty Form. Without it, you won’t have warranty coverage.

What do I have to do to activate the lifetime warranty?

Make sure you complete the warranty application form, or it will not be valid. Note that you will need a multi-meter to complete the required tests.

CosyFloor Fixing Strip Installation

I’ve used similar strips from other companies and they say to install with backboard and self-leveling concrete. Your fixing strips instructions don’t mention those?

That’s correct! You do not need backerboard for installing CosyFloor fixing strips. For wood subfloor, screw fixing strips directly to subfloor. For concrete subfloor, usse contact adhesive such as 3M 90 or similar. After you’ve laid out your fixing strips around the perimeter of the room, also add fixing strips parallel to the wall at 5′ intervals. This will help keep your heating cable in place when you start running them throughout the room. Once the cable and thermostat floor sensor are in place, you can pour a layer of self-leveling concrete, but it’s not required.

CosyFloor Thermostat Questions

My System is Giving Me an Error Code? What Do I Do?

Make sure the floor sensor is wired correctly and undamaged. If it’s not installed, switch the thermostat to ‘AF’ mode using the toggle on the back.

What Does GFI mean?

GFI means the system detected a cable fault and shut off for safety.
