When we had our home built we wanted to make sure that everything in the house was energy efficient even down to the furnace we used. I didn’t know much about furnaces so my husband thought it would be a good idea to do a little research. Once we had a chance to research we thought the hydronic furnace would be the best furnace to have installed in our home. So we talked to our builder and informed him of the type of furnace we wanted. He said it might cost a little more but we were willing to make up the difference.
