I talked with a Harman dealer today about a p68 corner install price of stove and vent thimble with oak. He mentioned I needed a pad meeting r19 or would that be r.19 any way they sell them. I said I was thinking of making one from plywood and tile. He said it would not meet r19. I see nothing in the Harman literature of an r19 value. this pad would have to side under hot water baseboard heating element in about a foot and a half section. so I cant go over 1 3/8 to 11/2 thick nor do I want to spend over 500 bucks for a 48 inch corner hearth pad. any way around this without screwing cement board to the hard wood flooring.. I figure my square footage is around 2400 sf with an open floor plan cape. set in a dining room corner it would blow both toward the kitchen, living room and stairwell to upstairs. He said he thought a p43 would heat it and probably on max a lot but use less pellets. So now im very confused on what I need for btu. I have a wood fireplace insert for back up and help but am 63 and tired of cutting and spitting stacking and lugging wood every few hours. What would your selection ideas be smaller one maxed a lot or bigger unit not maxed. also on the hearth heat rises and the pellet fire is not near the base like a wood stove. you would think all would need is ember protection with the tiles. I don't imagine you lay durlok cement board and tile it with out it fastened down to the floor. does it r19 or are they trying to push their prefab hearth pads. when asking about Englanders he said about half Harman sales is replacing cheap pellet stoves who's motors augers fail. I like the construction , ash draw, any pellet, and less cleaning aspect of the Harman. they also appear pretty well built. I live in eastern Maine we get some pretty cold days thru out the winter. Anyone want to chime in on btu suggestions and hearth pad. I don't want to raise the hearth above the baseboard. little more involved to mobe the baseboard because it has an anti freeze blend. buring wood I didn't want the pipes to freeze.
