Replaced our electric system with gas 2018. One year warranty on boiler ran out and have had nothing but trouble with it. Keep shelling out money on a bad boiler that should have been replaced. Determined that we need to find a new contractor to get the problem resolved. Probably will have to pay for a new boiler. Sitting here with no heat writing this review. Don't recommend Mr. Walenta
