Braveheart16 17 | 127 16 Aug 2016 #1I am in the process of deciding on a heating system for my house and not sure whether I should install a boiler system or gas. I have a gas pipe to the house which has never been connected. At present I have an old inefficient boiler for heating. I have read past postings on home heating costs from a few years ago but would like to know what the current opinion is on the most economical to use...I like the idea of using wood pellets but understand that on average, over the course of a year more pellets are used compared to ekogroszek 'coal'...Obviously I would like to make savings and at present it would seem that 'coal' is the likely winner. I believe that gas could contain hidden costs and be reasonably expensive to run.My other concern is future legislation which I understand will impose restrictions in various regions throughout Poland on using boilers and solid fuels and is likely to take effect from 2019-20. Not sure if this is likely to become law nationwide but would welcome your views on this.
