Fireplace tube heaters.
While looking for alternative heat sources this winter, I came upon several websites advertising these heaters. Here is a URL that will give you a description of the heater (I am not advertising this website; merely used for the purpose of description!):
I was really impressed by the claim they deliver up to 60K BTUs. Does anyone on the web use such an item? I would be interested in your comments.
The house contains four fireplaces and since the design of the house is an antique saltbox, I am concerned of the depth of the fireplaces vs. the size of the heater tubes -- the fireplaces, especially on the bottom floor may be too deep; while the ones upstairs may be too shallow! The deep ones may not be a problem but it may affect the draft.
Thanking you in advance for your time.
