Gas stoves are usually more expensive to buy but cheaper during use compared with electric stoves. Not only are gas stoves more energy efficient but gas is also usually cheaper than electricity, which results in operational cost savings.
Gas Boiler. Gas boilers are typically very large and used to heat large buildings rather than a home. Replacement costs of a gas boiler can range from $2,500 to $4,000 for a mid-efficiency boiler and $5,000 to $9,000 for a high-efficiency boiler making them significantly more expensive than a gas furnace.ingle stage, 80% efficient gas furnaces typically cost $2,000 or higher, moving up to a 90% efficiency range of this same type can cost $3,000. To move into the 95% efficiency range with a multi-stage or modulating furnace that feature variable speed blowers can cost $5,000 to $7,500.
