No, it should only be a matter of swapping out the stove itself. However, we always recommend that every stove is installed correctly and according to Building Regulations so it’s a good time to upgrade flues or hearths, should the existing ones not be to the correct standard.
Any flues, hearths, etc. that were installed for a solid fuel stove and in accordance with the correct standards will comply with your new wood pellet stove installation. All our wood pellet stoves have their own energy efficient circulation pump built-in as well as a small expansion vessel and a raft of safety features.
