I am looking for someone to help me size and design a heating system for my 3 family house in Carroll Gardens. I need to buy the boilers, radiators, ect. but installation is included in the contract I have with my general contractor. I made a big mistake by assuming that the plumber doing the job would also design and size the system but he won’t do it. I have done the heat loss calculations and cubic volumes for all the rooms but realize that I am in over my head. Any ideas who I could hire to just do the design without doing the installation? Or am I making it more difficult than it needs to be and I should just wing it?
Thanks to anyone with advice.
