High standard installation



A chimney is not just a chimney. Different legal requirements must be met, e.g. building regulations and air guidelines must be complied with and often OML calculations must be made.

Leave your next purchase and/or replacement of your chimney to NISSEN energy, and get a environmental correct chimney installation.


Contact our Sales Dept. for more information on purchasing and installing the chimney.
