This b-18 Thermolec electric boiler is in great used condition. I want to say it is about 5 years old. We had it hooked up to heat a 1000 sq ft apartment ended up doing a pretty big add on so we took this one out and put in a bigger gas boiler. It was working great when it was removed about 6 months ago we just needed something bigger.
