That unit appears to have electric heating. As for the listing price I can see 2 other units that have sold in the complex in the past 6 months one at 160K and another at $150. However with condo pricing the common misconception is that all units in the same complex should sell for the same price. While that may be true with new units, the should not be thought with older complexes. Over the course of 20 years, as I am sure you can imagine, there are tons of personlization that can be done to make some units sell for more or less than another with the same square footage, heating....etc.
Ultimately, the buyer sets what the market value is on any real estate. You can price a property for anything you want to, that doesn't mean you will get that price from a buyer.
If you are considering buying, selling or both, I would highly recommend working with a realtor. They should be able to guide you through the entire process, including making sure that if you are selling in today's market that you price your property correctly for an easy sale.
