Please note, comments must be approved before they are published, An Interview with Thom Rider: Woodworking Expert, How did you get the idea to create your helpful YouTube videos? Determine where you want to install the heater. Connect the black circuit feed wire to the wire lead on the thermostat marked "Line," using a wire connector. Line-voltage thermostats for 240-volt heaters come in two types: single-pole and double-pole. 4. Be sure the heater is clear of all obstructions and that there is a 6 inch clearance between the heater and drapes. Turn the circuit breaker off at the main electrical panel that supplies power to the existing baseboard heater and thermostat. In most 240-volt wiring situations, the circuit wires will be black and white; it doesn't make any difference which wire lead gets attached to which feed wire, as both are hot. Here, we’ll review the top 10 best thermostats for baseboard heaters on the market today. A new lin… For wall-mounted installation, these instructions also assume that an electrical box has been installed in the proper location in the wall. However, connecting a line-voltage thermostat is a fairly simple job that you can easily do.

One heater is 1500w and the other is 2000w. Replace wiring compartment cover and secure with screw previously removed. The thermostat has a total of four wire leads: two marked "Line" that connect to the circuit feed wires entering the box from the circuit breaker panel, and two marked "Load" that connect to the circuit wires that run onward to the heater. Only disconnect one factory connector. How do I connect my new thermostat? Use wire connectors to join the outdoing circuit wires leading to the baseboard heater(s) to the wire leads marked "Load" on the thermostat. A wiring diagram is a streamlined standard pictorial depiction of an electrical circuit. 1. PDF Version. The seam at the junction of the wall and floor behind the heater should be caulked to prevent dust from being drawn into the room. The thermostat may be attached to an external wall or to the heater itself. Locate wall studs closest to the supply wires and position the heater against the wall. Use a wire connector to join the white feed wire to the white outgoing wire(s). It's economical, yet rugged. Install two screws through the cover into the junction boxes. Determine which side of the baseboard you plan to wire. It has a simple dial-type mechanical control and is UL- and csa listed for safety. If not, the arrangement will not function as it ought to be. This project assumes that the electrical cable for the line-voltage thermostat has already been routed from the circuit breaker panel to the thermostat location on the wall and from the thermostat location to the baseboard heater. The heater should also be flush against the surface of the wall. Locate wall studs closest to the supply wires and position the heater against the wall. You can use a stud finder to do this. For best results, place the heater under a window. Connect supply wire to the heater. Mount the heater securely to the wall with nails or screws. 1 - Identifying your Wires. Use an electronic stud finder to … If the circuit breaker stays on but the heater doesn’t warm up, the problem is the thermostat, the heating element or the limit switch. Do not install heater against vinyl wallpaper, paperboard, or low-density fiberboard surface. Timothy Thiele is an electrician who advises residential DIYers on how to make home installation projects safe and easy. 240-volt heaters use less current to produce the same amount of heat as the same wattage 120-volt heater. I have a Honeywell four wire thermostat for electric baseboard heater. Not only are they effective but they're so subtle and provide an even flow of heat most people have come to appreciate. Route ground wire to the baseboard heater. Follow the installation instructions above for mounting and wiring your baseboard heater and you're all set!

Remove the top of the cover off the center bracket and off the immediate supports. Such work should be done by DIYers only if they have substantial knowledge and experience. This allows wiring with a smaller gauge wire which is both cheaper and easier to install. Winter's on the way and one of the most popular forms of supplemental heating is a baseboard heater. The bare copper wires from each cable entering the box need to be joined together with a wire connector, and the metal box also needs to be grounded with a "pigtail" wire that links to the circuit grounding wires. When it comes to heating your Read More, Temperature accuracy within 1-2 degrees of settings, Safe choice with built-in thermal cut out. For use with electric baseboards, convectors and fan forced heaters, this thermostat is a practical option. Tuck the wires into the electrical box and secure the thermostat with the mounting screws. Route supply wires to the thermostat wiring box if not already present. Likewise, some heaters are wired into a wall-mounted thermostat, while others have their own thermostats on the face of the unit. Checkout Our Top Pick Of Best Thermostats For Baseboard Heaters. Double-pole thermostats offer a true "off" function because the current to the baseboard heater is completely interrupted when the thermostat is off. (On the old thermostat, only the two hot black wires connected to is and the two hot white wires were wire nutted together.) The remaining pair of wires of the LOAD side attach to the baseboard heater lead wires which are directly connected to the heating element of the baseboard unit. The supply wiring can enter the raceway without using a knockout if needed. For programmable thermostats and smart thermostats, c-wires are essential for setting a schedule or having your heat or air conditioner turn on at a desired temperature.While some units can run without a c-wire, even brands like Nest … Connect one supply wire to one thermostat wire marked L1. Use wire connectors to join the two feed wires entering the box from the power source to the wire leads on the thermostat marked "Line." These preliminaries will be already be handled if you are replacing an existing thermostat, but a new heater installation will involve running a new cable, installing a new electrical box, and mounting a baseboard heater on the wall.

Most will specify either a single-pole or double-pole thermostat, though some may allow either type. Leave the red wire disconnected and cap loose end with an approved wire connector, or wrap loose end with electrical tape. If the thermostat is controlling two or more thermostats from the same location, then each lead will be attached to multiple outgoing wires. There are numerous ways to wire an electric baseboard heater, depending on your heating configuration and whether you are connecting a single-pole or double-pole thermostat. Because a baseboard heater doesn’t blow air, it’s quieter and heats more evenly. A line-voltage thermostat can control a single baseboard heater or several heaters wired together. a. It shows the components of the circuit as simplified shapes, and the power and also signal links in between the devices. It operates much the same way as a dimmer switch providing variable control to a light fixture. Most baseboard heating systems use 240-volt circuits, but 120-volt heaters are also available, as they are often used to provide supplemental heat in individual rooms that are also served by a central heating system. Each component should be set and connected with different parts in specific way. There are two brands that we carry requiring hardwire installation, Cadet and QMark.

Wiring for a 240-volt single-pole thermostat is similar to that for a double-pole, but in this case, one of the hot wires will simply bypass the thermostat and pass onward to the baseboard heater. The back of the heater has star punch dimples that allow nails or screw to pierce the sheet metal. Single-pole thermostats are sometimes known as "two-wire" thermostats, while double-pole thermostats are called "four-wire." Unlike the low-voltage thermostats that control central heating and air-conditioning systems, electric baseboard heaters use line-voltage thermostats that are installed as part of the full-voltage circuit powering the heater. This is also a hot wire, but in this case, it bypasses the thermostat and runs directly to the heater(s). The wiring should be installed into the baseboard heater using a protective bushing or cable connector. For standard baseboard wring on the right or left 120V or 240V supply.
