I work for an utility in the planning area. Recently there was a change in calculating the algorithm of residential boiler and furnaces. For the purpose of planning, we need a statistically accurate value for input capacity. I was wondering if any one in this community have a list of data compilation of boiler or furnace input capacity. I started the process of compilation and it was an arduous process going to individual HVAC manufacturer website to obtain the input capacity for different models. I am sure someone in the community have gone down this same path and perhaps would be able to share that list. If you know someone with that information kindly refer. Any help is appreciated. Thank you.
