The insulation cost is a one time expense. Due to the higher voltage, 240-volt models operate at lower amperage and tend to be slightly more energy-efficient than 120-volt heaters. The two second wires incoming and outgoing will now have an extra short wire attached to them; terminate that wire on the line side of the thermostat. Wiring is as simple as adding a 20-amp. When I attempted to install the heaters I found that the thermostats, heaters, and even breakers have connections for only 2 wires.
Tape the wire nut to the wires with electrical tape. Double check the wiring to be sure the electrical supply wires are the same voltage as the heater. At the bottom of this internet site there is also a Wiring A 240v Baseboard Heater photo gallery, if the photo above is insufficient for you. What are the mfr's and model numbers of both the heaters and the T-stat? Look at the back of the thermostat and locate the writing that shows the line and load connections. Do not install heater against vinyl wallpaper, paperboard, or low density fiberboard surface. Base the wire selection on this number. We welcome your comments and suggestions.
Attach the black wire to the load side of the thermostat. You will also need to choose the heater-mount or wall-mount type of thermostat. Each has a different type of cover needed to complete the installation. These are a little more expensive that the cheaper mechanical style, but will normally maintain the temperature of the room closer to the set number. You can use 10-gauge cable on a 30-amp circuit instead, but you will find it much more to difficult to run the wire due to its thickness.
Instructions for converting baseboard heating radiant heating. Most spaces require 10 watts per square foot of space for homes built since the 1970s. This signifies that it is a hot wire rather than a neutral wire. If the thermostat is turned on at this point all wires may indicate voltage; if this happens either turn the thermostat off or to a very low setting and retest. The two leads from the panel go to L1 and L2.
Is the thermostat going to a junction box with two lines running from the box to the two separate heaters - red to red, black to black in each? The white wire will get a piece of black or red tape wrapped around it near the breaker and at the thermostat and heater connections. The cheapest of the line voltage units, these thermostats operate on mechanical principles rather than digitally. Without a second hot there is no power to run the stat. The bare ground wires connect to the ground screw or ground wire on the thermostat, via a pigtail wire. Twist the wire nut firmly in a counter-clockwise direction until the wire nut is secure. Both white circuit wires should be labeled as hot with a band of black or red tape.
Installing 240 volt heaters is best as wire sizes and number of circuits are significantly reduced. Set the heater aside and drill an appropriate sized hole into the wall or floor. I want both controlled by one thermostat. It is much more convenient and efficient to connect the baseboard heaters in parallel and hook them up to one wall-mounted, across-the-line thermostat. Defrost Thermostat Frigidaire 240V Baseboard Heater Wiring Diagram, size: 800 x 600 px, source: arkiplanos. Exercise care when working with electricity.
Most are connected via wire nuts to wires coming from inside the new thermostat, but some can have screw terminals to attach wires to. Look at the other answers on this page for wiser advice. Both white circuit wires should be labeled as hot with a band of black or red tape. If it has any other color of insulation, however, it is a hot wire and will need to be used with the new thermostat. If you're moving the wires through the knockout, be sure to use a cable connector and leave 6-8 inches of wire for heater connection.
Run another cable from the junction box to the second heater, and repeat the above steps. The thermostat wiring connections vary for 240-volt and 120-volt circuits. Programmable thermostats are the ultimate in comfort and. The heater includes nail point marks showing correct locations for mounting holes. No matter how small the order or how far it needs to go, ShippingPass provides unlimited nationwide shipping. Make these splices three-way splices by connecting the wires carrying the power to the second heater to them. Place it either under a window, along an outside wall, or as close as possible to an outside door.
Then, attach the bare ground wire to the ground screw. Insulation is inexpensive over the long run. For example, if the heaters add up to 4,000 watts and you divide that by 240, you get just over 16 amps. Notice that you will be working with three sets of wires: the electrical supply wires black, white and green ; the electric baseboard wires two black and a green ; the single-pole thermostat wires one black and one red. Locate wall studs closest to the supply wires and position the heater against the wall. When wiring a baseboard heater with a separate thermostat, you must install a length of circuit cable from the thermostat box to the heater. Also make sure that you're using a proper 2-pole breaker at your electrical panel and if using an outlet, use the correct type to match the circuit's amp rating.
