how much is a gas boiler for a single family home with installation??
This would be entirely dependent on the size of the house, which is the controlling factor for the size of the boiler, and difficulty of installation. Call a local business and get a free quote. In fact, why don't you get three so you can compare!
The average cost for just the boiler runs anywhere from $1,799 up to several thousand. A new boiler replacement with labor can cost between $4,000 to about $8,000+. It just depends on which boiler you are looking for and how efficient you want the boiler to run. Remember, you get what you pay for--money spent now on a great system can save greatly on your bills over the next 10-20 years.
