No. The black is 220, the red is 220, and the ground serves as the neutral.
the last answer "no" is correct but the reason is not. the ground is still a ground. the red is 110v and the black is 110v. together they are 220v. the neutral or (common) is for a 110v return. for example a stove or a dryer will have 2 hots a common and a ground because they use 220v and 110v. 220v to power the heating elements and 110 for the controls, light bulbs or the outlet on a stove. A construction heater only uses 220v and only requires the two hots and the ground for safety.
Any ground wire has to be connected to an independent ground wire that returns directly to the distribution panel and not to the neutral of the circuit.
This is an indication that your heater core is leaking. To stop the leaking you will have to replace the heater core or stop using your heater.
If the heater is rated as a 3 phase 480 volt heater then a neutral is not needed. If the voltage stated is 277 volts three phase then a neutral is needed.
does a water heater require a ground wire?
directions for closing above ground pool with heater
No, not really. The two hot legs can be opposite legs of a 120/240 V split phase power source. You still do need a protective earth ground, however, but the heater itself does not require a grounded neutral to run.
Car will make when running even if heater core is not burned out.
You have to turn the heater on, by running to the right on it.
Problem solved: Bought a used heater control, installed it in minutes, and all is well.
check the fuse or the ground on the heater
Take both heater hoses off at the heater and the hose running from the front, attach it to the rear of the engine.
Yes it can be done that way. Just make sure to use a double-pole breaker to ensure each wire is on an opposite phase.
This is only valid in parts of the work using 110/220 Volt split phase power system. There will be 110V from each of the hot leads to ground/neutral, so connect your outlet to only one of the hot leads, the neutral lead and the earth ground lead. This may be a problem with a dedicated 220V circuit as there will likely be no neutral line. Another note - this could well cause an unbalanced electrical load across the two pole breaker. If the breaker has a rating of 20A and the 110V circuit draws much of that current, the heater will likely trip the breaker.
If you are not getting heat out of the heater, there are only a few things that could be wrong. The first is low coolant. You can't get heat without coolant running through the heater. If it is low, sometimes it has to be bled of air bubbles. If both heater hose running to the heater are hot, you have circulation. If not the heater could be plugged or not getting the coolant to circulate. There is also a damper in the heater system to stop cold air from bypassing the heater and that needs to be checked.
immersion heater because heat is sent directly to the object and it heats faster
Infra red radiation directly, or by heating the air in the room (such as when the heater is around a corner. Or both.
Provided the heater is of a low wattage it should not affect normal running of the car
The heater control valve is on the left hand side of the engine bay, under the air intake duct. it has two heater hoses running to it and one vacuum line running to it.
In a balanced system nothing will happen. In an unbalanced system the neutral carries the unbalanced current. Removing the neutral in an unbalanced system will cause different voltages and currents to be applied to the devices connected to that circuit. This is the reason that a ground plate or rods are connected to the neutral bus bar to take over in case the utility company looses a neutral at the connection to the mast head. <<>> No power can/will flow. - Unless you're using a /3 wire removing the neutral then will the only give you 240v - example Hot Water heater You need the neutral for 120v circuits.
