INTEGRATION-KIT-PLUS-240V Frequently Asked Questions

While WarmlyYours electric radiant floor heating 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.

A floor heating system can work as a supplemental heating source and make the basement warmer. If more heat needs to be added to the room, you can experiment with setting the floor heating thermostat to higher temperatures.

The breaker and wire sizes are selected based on the total amperage of the WarmlyYours heating system connected to a single thermostat. This information is on the WarmlyYours heating system's installation plan, electrical plan, or UL label. Based on guidelines from the National Electrical Code: loads up to 16 Amps may utilize 12 gauge wire with a 20-Amp breaker, and loads up to 12 Amps - 14 gauge wire with a 15-Amp breaker. Local code and/or other factors may change these guidelines.

The ground wire in the floor mat must be connected directly to the ground wire of the supply or to the house ground wire.

Cork flooring can be used with floor heating if the r-value is under 1. You will need to find the r-value of the flooring you choose and let your account manager know during the design stage. Cork flooring should have a low r-value to minimize trapped heat.

Most low voltage HVAC thermostats are OK to use with tile floors. If you are heating wood, vinyl, carpet, or any other flooring products that have a "maximum temperature" limit, then low voltage HVAC thermostats are not recommended UNLESS they have an input for a floor sensor. Check with the low voltage HVAC thermostat manufacturer about floor sensor inputs first, before buying a third-party integration kit for these types of flooring products.

nJoin unit is designed to work with nSpire series thermostats. If you would like to use third-party thermostat or controller, we recommend using our Integration kits that will receive “call for heat” and activate the floor heating.

A Warmly Yours indoor floor heating system should not be installed with a GFCI breaker because GFCI protection is built into the thermostat and power module.  And while it's not always required, we strongly recommend a dedicated circuit for each thermostat and power module to limit the occurrence of ground fault nuisance tripping caused by multiple GFCI devices on a circuit. The amperage of a breaker would depend on the amp draw of the heating system. For example, a TempZone Flex Roll (which provides approximately 15 watts of energy output per square foot) that is providing 15 square feet of heating coverage will draw only 225 watts ( 1.9 Amps), so a 15 Amp circuit would suffice.  Always size breakers according to your local Electrical Code requirements. 

WarmlyYours suggests contacting the manufacturer of the home automation system to determine compatibility or how it recommends operating an electric floor heating system.

An area where large furniture will cover the floor should have enough clearance underneath to allow air to circulate. Any areas where floor heat may be trapped (rugs, box bottom furniture), let your sales rep know so we can design an installation plan around these areas.
