Did you know that by replacing your old boiler with a new condensing boiler you could save up to % on heating bills? you could save even more with the correct controls! Sewerage/water mains issues should be referred to. Kurt at koegel plumbing is amazing!! should have called him sooner thank you!!! Was very friendly and knowledgeable shared some helpful hints very happy. Making sure pipes have proper slope and the job is done right! I want to be judged by individual.
