Open Fire vs Woodburning Stove

Leave a comment

What are the benefits of a solid fuel stove over a traditional open fireplace?

Most solid fuel stoves are approximately 40-50% more efficient than an open fire and allow the user to have control over the rate of burn and heat output to the room.  Often a large percentage of the heat generated by central heating is lost from a room where an open fire is present (even when not in use).   The installation of a stove will mean that the room is much warmer as the air flow is greatly reduced due to the installation of a register plate and the ability to close the air controls fitted on the appliance.

Why do you need a chimney liner?

A customer that walked into our showroom this morning reminded me how often our customers are surprised by the ins and outs of fitting a woodburning or multi fuel stove. Many assume that it is just a case of placing the appliance into an opening – job done! However it is actually neccessary (and beneficial) to fit a flue liner to every solid fuel appliance.

So, why do you need your chimney lined?

It is a requirement under the Building Regulations that any stove has to be installed with a connection to a flue lining. When a chimney was designed originally for an open fire it was typical for a fire to burn 12kW of fuel per hour and give nominally 2kW into the room.

But when a stove is fitted, for every 2kW it gives into the room there is less than 1kW of heat going up the chimney. Thus there is insufficient heating of the clay or stone masonry if a stove is fitted without a lining. In this situation it is typical to have tar condensation and an incorrect draught for the stove to work correctly and efficiently. A chimney lining will also prevent smoke and fumes from your fire from leaking into other rooms of the house.
