How do I determine the voltage of the wall thermostat for an electric baseboard heater.?

There are two different types of thermostats for electric baseboard heaters. Line voltage and low voltage. Connection to a line stat used the source voltage from the distribution panel and operates like a switch. Because the baseboard heater usually is 240 volts the stat breaks both hot inputs. The stat output goes to the baseboard heater. When the stat calls for heat its internal switch closes and applied the 240 volt to the heater. On the side of the stat will be a voltage and current rating that the stat must operate within. The other type of thermostat is used in low voltage installations. Instead of the switch being in the wall like a line stat, there is a low voltage relay mounted in the baseboard heater itself. This relays coil is usually 24 volts AC. An external 24 volt transformer is needed to supply a voltage to this coil. This 24 volt supply is first taken to the low volt stat and an internal low voltage switch is used to energise the coil of the relay in the baseboard heater. The difference between the two stats is very noticeable in that the line stat is very heavily built with strong termination points. The 24 volt stat is very flimsy in comparison as the current it has to handle is only the relay coils current.

How many BTUs in a 6 ft baseboard heater?
BTU's are not based on the length. To answer this question the wattage and voltage of the baseboard must be given.
When checking an electric heating element you read voltage but no amperage What can you determine about the heating element?
the element has a open in it !
Room with electric baseboard heaters that add up to 4500 watts which is to much for one 20amp 240 circuit. Can I use a low voltage thermostat with a relay rated for 24 amps on this circuit to fix this?
A low voltage relay will not solve the problem. Even through the relay the current will still be over what the code states is legal for the circuit. The legal wattage applied to a 20 amp circuit is 20 x 240 = 4800. The circuit on electric heat can only be loaded to 80% of the ampacity of the conductor. 4800 x .8 = 3840. However you want to distribute the baseboard heaters, there should not be any more than 3840 watts on the 20 amp 240 volt circuit. If you want to rewire and use #10 wire that is rated at 30 amps then the connected wattage allowed would be 30 x 240 = 7200 x .8 = 5760. A 30 amp circuit is the maximum size that can be used for surface baseboard heating in a single family residence.
If voltage is high will the resistance be high?
The electric resistance is related to the diameter and extension of the wire submitted to a determined voltage which will determine the electric current flowing into the wire.AnswerVoltage has no effect on resistance. Resistance is determined by the length, cross-sectional area, and resistivity of a material (resistivity is affected by temperature, so temperature indirectly affect resistance).
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
How do you wire in a lowvoltage thermostat control to a baseboard heater?
Most baseboard heaters use hi voltage thermostats.
Where can you find thermostat for an electric baseboard heater HPH15002E?
any hvac supply store (Grainger) ask for a line voltage stat, they have many styles but they are all the basic same
Is there a switch available to control power to a thermostat for 20A 240V electric baseboard heater?
There are two types of thermostats. One is a line voltage stat. This is in effect a switch and when turned to the off position the voltage is interrupted and the heater will not operate. The other type of stat is low voltage. There will be a relay in the baseboard heater that the thermostat is connected to. With this type if installation to turn the power completely off you will have to turn the breaker off that feeds the circuit.
If a baseboard heater has its own thermostat can you bypass it and wire it to a wall mounted thermostat?
Yes, but be sure you buy what is known as a `line voltage thermostat`when you do this since you have no control voltage but are simply breaking a line in the main power feed to turn the strip on and off.

Low voltage thermostat already set up for baseboard heating that you wish to replace can you use any low voltage thermostat or does it need to be baseboard specific?
You may use any thermostat with the same # of stages of Heating and/or Cooling. In order to determine the # of stages of heat, remove the cover and thermostat, look on the subase to see how many W terminals there are with wires connected. W1 with a wire would be single stage, W1 & W2 with both wired would be two stages of heat. If two stage, it is important these are wired back correctly on the replacement, so as not to bring on the second stage first. If it is a Heat/ Cool application Y is the cooling terminal. In both cases R or RH is the power feed from the unit(boiler) for heat, and R or RC is the power feed from the cooling unit(air handler).

Can an ac element be run on DC?
DC voltage can be used to run almost any device utilizing an electric heating element, including resistive baseboard and electric water heaters. In these applications, electrical current flowing in a heating element produces heat due to resistance.
What do line voltage thermostats have that low voltage thermostats don't?
Line voltage sometimes varies according to how much load there is from neighbours and other users. When the voltage is high, the water heats more quickly so that the thermostat cuts out sooner, so the amount of energy used ia about the same. <<>> It is the difference in construction of the two thermostats. A line thermostat uses a bi-metal sensor to open and close the line voltage. The room temperature fluctuation has to be greater between the stat turning on to off, as the differential setpoint can not be regulated as fine as a low voltage stat. A low voltage thermostat uses a mercury switch that is operated from a spring that senses the room temperature. Low voltage thermostats do not control the line voltage to the heater but use a remote contactor to open and close the voltage supply to the heater. There is a compensator in the low voltage stat that can be set for the contactor's coil current. This way the temperature generated by the coil of the remote contactor is nulled and the thermostat only reads the room temperature. The differential setpoint on a low voltage thermostat has a finer setting than that of a line thermostat, so a more accurate temperature is maintained.
