My gas boiler is old and I was thinking about switching over to wood. Simple right? I thought so and in researching the topic I am now completely overwhelmed with the information I have found. I understand the work that goes into maintaining the wood but not sure my piping is adequate and if I should get a gasification or old style boiler. My house is about 1600 sq ft. and I have 7 cast iron radiators in the house. I have a chimney that most likely would need a liner and i have no water storage. Also my house was built in 1890. Any guides to get me pointed in the right direction to some basic do's and dont's would be much appreciated. Also is a catalyst the same as a gasification boiler?
