Efficient fireplace inserts

They look great but that homey glow real fires produce sends heat right up the chimney as the fire sucks warm air from the rest of the house.

“Ninety-five percent of the heat is lost,” said Prof Kevin Eigel, who studies energy use in homes. “The rest of the house gets cold even while it’s warm right around the fireplace.”

Fortunately, homeowners have more options than ever to get more use and heat from the fireplace.

Options range from a simple blower system that costs less than $1,000 to wood-burning inserts that can cost more than $5,000 but can heat an entire home.…

The Pembrokeshire planners decided earlier this month that the hobbit-style home is not suitable for the area, even though it is built entirely of natural materials and uses renewable energy and rainwater. The application for retrospective planning permission was declined on the grounds it could not make a positive environmental contribution and has an adverse impact on the semi-natural habitats in this location.

State by state guide to green tax incentives

Tom�s Shell price list
price rise
