I have a couple questions. We have a older home that has a lot of wood flooring. We have not insulated under the house yet and I am wondering if our Englander will be able to put out enough heat to even feel it? Part of the den does have carpet but you can feel the cold air coming up thru the flooring everywhere else. Also, where is the best place to purchase your insulated pipe? Anyone else not have your flooring insulated ? Thanks in advance!
