Modern heating devices


Pellet fired stove offers comfort also

Pellets relates to a fuel that is still underestimated. The reason may be the fact that many persons are not familiar with use of pellet fired boiler for heating purposes. It may seem that use of biomass, namely sawdust or straw as a fuel in central heating boiler causes a lot of hassle and is labour-intensive. Nothing more misleading!
