I have installed a 240-volt heater with a wall mounted thermostat I am
using 14-2 wire. I was told a builder who talked to an electritian about
the wiring with 14-2, he said use 2-15 amp breakers and make white
and black hots. Is this right? And if this is how do I connect them to
the heater and thermostat? I now have no power to the heater with
the way I have it hooked up now.

i am concerned with the wire size, 14 will not carry much amperage at all. 2 single pole breakers, one powering white and one black is not at all how it should be done
a double pole 30 amp (if that is what is called for) with a #10 at least is what i would do
how many amps are we talking about here?

With Hvac for sure all the way. You never want to use 2 seperate breakers on an appliance. If there is a short and it needs to trip the breaker you want it to kill both legs not just one.

Please listen to HVAC! 14 gauge is way too small for your job..not only will it continually blow circuits (if you're lucky)-it will not carry the load and is a tremendous fire hazard
go with #10 and 30 amp breaker.

14 Gauge wire might be penty for a single heater. It depends on how large/watts your heater is. For example, a 1500 watt, 240 volt heater will only pull about 6.25 amps. Using a pair of 15 amps breakers is plenty for 1 or two heaters. However, I disagree with using 14-2 wire. I would use 14-3 wire - the red and black are hot, the white is neutral, and bare is ground.
