Using a standard open fireplace is an inefficient way to heat your home.
It strips the air you have already paid to heat, leaving your furnace working overtime when the blaze gets extinguished.
You can look back to ancient green heating technology to finding an efficient replacement.
Meteorologist Shannon Murphy explains in, "Your Green Life."
A fireplace in a home on a cold Northland night causes families to gather round.
"It tends to bring more of a sense of home to a place," said Eric Moshier, a heater mason
But are inefficient in home heating.
A masonry heater is ancient technology, but a growing green trend in home renovations.
"That's the biggest advantage with them... that you are using up all the heat."
The stone used in building the heater allows the fire to burn at higher temperatures, which reduces emissions.
It also allows heat to radiate long after the blaze is extinguished.
"They are a good choice because they burn a small load of wood very efficiently and can heat a house of about two thousand feet on about three cords of wood per year," said Moshier.
Although costs start just under ten thousand, it's an investment that will see payback for years to come.
"In Minnesota we heat for 6 months out of the year, and with a masonry heater, normally when we build them, they are built to last for generations."
In Duluth, meteorologist Shannon Murphy.
The trend of masonry heaters is catching on here in the Northland.
Eric's work load has doubled since this time last year, and he is already booked 4 months in advance.
