Heated Floor under Vinyl

Vinyl flooring and luxury vinyl tiles (LVT) including Amtico and Karndean ranges are well-suited for use with underfloor heating.

Underfloor Heating under Vinyl Floors

Warmup offers a wide range of products for vinyl underfloor heating. Electric underfloor heating is suitable under vinyl floors. The temperature of the heating system with vinyl should not exceed 81°F. Therefore, if you are considering radiant heating with vinyl planks as the sole source of heat, carry out a heat loss calculation first to ensure the heated floor will be providing you with sufficient amount of heat.

Electric Systems for Vinyl Flooring

The most suitable underfloor heating system to use with vinyl flooring is dependent on which kind of vinyl flooring you are using and whether the room you are installing the new system in is a ‘Wet’ or ‘Dry’ room: bathrooms typically being considered Wet and living rooms, bedrooms, kitchens being Dry.

There are different types of vinyl flooring with properties that influence specification requirements for an underfloor heating system. Be sure to specify with your estimator which type of vinyl flooring you will be using.

Dry Rooms

A dry room is a room without a significant water element in it. Rooms like bedrooms, living rooms, hallways are so-called dry rooms, as well as kitchens, even though they feature sinks and often washing machines / dishwashers. The Foil Heater electric underfloor heating system used with Warmup’s Insulated Underlay, which separates the system from the floor finish, is suitable with most vinyl floor finishes in dry rooms. The Foil heater is not compatible COREtec or LVP.

The Warmup Insulated Underlay is a thin insulation barrier that reflects heat upwards, making the underfloor heating system more efficient and effective. The underlay also reduces contact noise and acts as an effective moisture barrier.

This system is not suitable for wet rooms as the Insulated Overlay may expand due to excessive moisture. It is important that you check with the vinyl flooring manufacturer on the types of underfloor heating systems that are suitable to use with their products. Some floor manufactures only allow the use of underfloor heating systems embedded within a slab / leveling compound.

Wet Rooms

Underfloor heating can be installed in wet rooms with vinyl floors. Depending on your project specification we recommend the DCM-PRO, StickyMat or Loose Wire Systems. Remember to always cover the underfloor heating system with a 3/8″ deep layer of self-leveling compound to protect the system from moisture before the vinyl flooring is laid down.

StickyMat features an ultra-thin 1/8″ wire that does not raise the floor levels. The system consists of a pre-spaced heating wire readily attached to an adhesive mesh.

The Warmup Loose Wire System (also known as NADWS) is perfect for designed irregularly shaped rooms.

Floor Temperature and Thermostat

The temperature of your underfloor heating system should not exceed 81°F with vinyl floors. The use of our thermostat and floor probe programmed to vinyl will ensure that your system does not heat the flooring above 81°F. The Warmup range of thermostats for underfloor heating has controllers for every need. The 4iE Smart WiFi Thermostat possesses incredibly smart features that ensure you enjoy your heated floor space safely and efficiently. The thermostat gives you total control of your heating settings and allows you to enjoy a warm room when desired with no wasted energy.

Transfer of Heat Limits

Everything above the heater, including underlay, overlay, and final floor finish need to be in the limits set in the table below. If the manufacturer of the vinyl flooring states that it must be used in conjunction with an underlay, the underlay must be no more than 3mm – 6mm thick and breathable.

When using the system with vinyl flooring, care should be taken to ensure effective performance of the system and we do not recommend installing the system if the limits below are not met. This may hinder the performance of the system and result in the system not working as desired.

The figures below are for electric underfloor heating systems only. Water systems have a broader range of limits due to the variables of the specification.

RSI  No more than 0.25
R-Value (US) No more than 1.42
U-Value No less than 4.0
