hi,i am thinking about installing a wood pellet central heating system and getting rid of the oil system.the boiler for the oil is in the utility so i would like to install the new system in the same place using the same plumbing that is already in place.just wondering has anyone already done this and if so is it a success also if its true how much cheaper it is to run.also would like to know if anyone has installed a domestic wind turbine as a back up or as a main source of power.thanks
