If you are certain that the heater has only two wires and that it is a 240 volt unit, here's what you do:
Bring in a 240 volt line.  There are three wires.  The red and black are the opposite phases and are each 120 volts above ground/neutral.  Connect them to the load wires.  If there is a neutral, connect that to the white wire, even if it is bare wire.  Bare wire and white are the same for all practical purposes.  If the unit has a fan, it will run on the neutral/white and one of the phases. Wire sizing is important.  Make sure you have a properly sized wire for the job Up to 20 Amps, use #12 wire.  If over 20 Amps rated, use #10.  Fuse appropriately.  
Make sure the power is off when doing this work!  240 will KILL YOU.

Need to install a hot water heater; need electrical diagram.

Generally you will have three wires

1. bare or green wire this is your ground and is secured to the outside of the water heater usually with a green colored screw provide with the unit.

2. connect the black wire from the house to the red wire on the unit.

3 connect the white wire from the house to the white wire from the unit.

In general as long as you hook up the two power wires from the house with the two power wires from the unit it does not matter as one wire will supply 110v and the other wire will also provide 110v..

Verify check and reverify that the power is off anytime you are working with wires.

How to wire recepticle for pump 240v, 2-speed fan motor 240v, purge pump 240v

If you are asking how to wire up a receptacle to run a 240 volt pump, you need to have a box on the roof first of all. You will need a 20 amp double pole breaker for this. You will need to pull 2- hot wires from the breaker box, 1- neutral, and a bare ground wire. Size of wire would be # 12 THHN stranded wire. A total of 4 wires. This would be to code. Or, buy enough Romex wire, #12 with ground wire and red, black, and white in side, tie into the breaker that way. Red and black will be your hot wires to pump, if it has no neutral you can use both the white and bare to ground, very easy to do.I hope this is what you wanted to know.

Wiring 15 amp 250v single outlet for wall ac unit use 12 AWG? blk hot; white taped red to other hot; bare grd to grd teminal?

You are using a 15 amp double pole breaker? If you are the two wires going into the breaker are you line voltage wires. A third conductor usually ground/bare would go to ground terminal. If you have 4 wires and the other one is white, that should be tied into the neutral ground bus back in the panel and is probably wired into the outlet as well. Buy a new outlet and you cannot go wrong.

I am finishing the wiring in my basement a I have 1 receptacle with 2 14/3 wires in it and another with 1 14/3 wire into it. I need to figure out the 2nd circuit and how to finish off the plugs

With most receptacles, you can connect up to two (2) sets of wires to the one recptacle/outlet. Be sure the power is off to the circuits you're going to be working on, by turning off the breakers in the main panel that go to these circuits.

Strip back the outer jacket at 8 inches on the Romex wires and be careful not to nick the conductors inside the outer jacket.

With the black, white and bare ground wires now exposed and separated from the jacket, you can stirp off 1/2 inch of the insulation off both the black and white wires. You can also tear off the paper wrapper that covers the bare copper ground wires too.

Now take the ground wires and twist them together for at least 3 inches, making sure that you start the twist near the back of the outlet box, where the wires come into the box. Use a pair of lineman's pliers to twist the bare wires together. Once you've done that, you can clip off one (1) of the bare ground wires that is left sticking out, as you only need one to connect to the Green grounding screw on the receptacle/outlet.

Now connect the two (2) black wires to the brass colored screws, which is the HOT or common side of the outlet. On the other side, connec the two (2) white wires to the silver colored screws, as this is the Neutral side of the outlet. Now you can carefully bend the wires to let you push them into the outlet box and screw the outlet into the wall box. Put on the plate cover and you're all set. Turn the breaker back on and you've completed the wiring.

On the box with the single #14/3 wire (w/ground) just follow the instructions above, except you only have one wire to connect to each side of the outlet, matching them Black to brass screw and White to silver screw and the bare copper wire to the Green grounding screw.

Hope you find this Very Helpful and best regards.

If you take thermostrat back off and connect the wires together will baseboard heater get hot. If not you may have bad heater. If it gets hot your new tstat may be bad. The way you have it wired is correct. Most line voltage tstats have a ground screw. Your 's may not but will work without one .
