Which is the most expensive heating system to buy?
Though the gas boiler is most expensive to buy at $3,500, the heat pump has the highest installation cost of $4,000, which nudged it to the top of the pile in terms of overall initial cost. The electric boiler had the lowest installation cost at only $350, however, the electric furnace came in with the lowest purchase price of $1,250.
How much does a solar heating system cost?
Most systems will also provide some kind of storage system so that you can have heat even when the sun is not shining. Active solar heating systems are designed to provide 40% to 80% of a home’s heating needs. Costs vary from $30 to $80 per square foot, installed. Deciding how many square feet you’d need for your home is a bit tricky.
What’s the cheapest way to heat the House?
