The honeywell tradeline thermostat would work as a direct replacement (no mercury in the new ones), however if your using just heaters and no cooling system off of it, you could Heat only thermostat from honeywell that would replace your unit as well. Both at available at Ace Hardware with the heat only unity being roughly 7 dollars cheaper.

The Black Wires from the md26 are your load(the heater) and the red lines are your line(power). The lines are also paired up on the thermostat with a red and black on the left and are red and black on the right. In the actual heater connect the black to the black wire and the white to the white and connect the grounds. In the thermostat connect the black from the heater to left side black( remember there are pairs left(black, red) right (black, red) and the white to the right side black connect the black from your power to the left side red and the white from your power to the right side red. Should be ready to go.

I am an electrician. You must measure the voltage across the black and red wires. Measuring each wire to the neutral will not cut it. If both your red and black wire are on the same phase the heater will not work.
To double check your wiring, measure the voltage across the two screws feeding your subpanel, they should be 240v or 208v depending on your power company. Then do the same at the breaker feeding your thermostat. Again it should read 240v.
If you have no potential across the screws it is possible that you installed an incorrect breaker. Not all breakers with two screws on them are 240v breakers. There is what is called a twin or split breaker that has two screws that are on the same phase. These are for wiring two 110v circuits, when you run out of spaces in the panel.
Double check everything. This is a relatively easy circuit to wire, even for homeowners. If the heater does not work them something is wrong so do not leave the circuit energized.
