Greenhouse Heating

20 years ago

I would like to know if anyone in this zone has used 120v heaters for warming. I live approximately 25-30 miles from the coast and in 31 years, I have not seen the winter temperature fall below 10 degrees Farenheit. I am ready to install electrical service and am curious whether I need a 240v line in addition to the 120v. If the 120v heaters are sufficient, I will not install the 240v line. Any information is welcomed.
