Recently, we were asked by a plumber to look at a home that has issues with the radiant heat. Turns out the homeowner (we will call him Ronny), runs a company that builds commercial office buildings, and the plumber that recommended us does the plumbing work.
On my first visit to the house, I was greeted by the housekeeper. She did not speak English and was unaware that Ronny, the homeowner, had made the appointment. I called Ronny and spoke to him; he apologized for forgetting the appointment. He stayed on the phone as I walked though his 7000 square feet house, and explained the heating issues to me while pointing out all eighteen radiant manifold locations, the boiler room and many of the thermostats. For about 30 minutes, I felt like a doctor that does telehealth. Once we ended the phone call, I spent about an hour in the boiler room taking photos, taking notes, and trying to figure out why the entire radiant system was not producing heat.
