Prior to getting our Englander, we were using A LOT of propane. No natural gas where we are. So after a year or so of research, we decided on the Englander 25 PVC. With the propane, the thermostat was set for 67 F. With the Englander, the temp is now 71 F. In the first year, the cost of the Btu produced from the pellets was half of what it would have cost with propane. The second year, we added the thermostat and slashed our pellet use by 30%.The furnace rarely comes on which is good for keeping down the propane that is used. We are happy with our Englander which is on the main floor of a two storey home. The center of the house is open so it allows the heat to move around freely and gets upstairs quite well. But of course, the finished basement is always cool and not very inviting. So we are thinking of adding an additional smaller unit downstairs, but with this I will have to go through the block wall. This could be a challenge with keeping proper clearance from the suspended ceiling and then window openings once I get it outside. Just seeing what others have done with keeping their finished basement warm.
