"That's what you'd quote me on? If I called you for a price on a replacement boiler, I mean." "Well," he said, "I have to add something for the domestic hot water load. You have an indirect heater, so we'd have to add quite a bit for that."
"Come with me," I said. We walked toward my office. "You're gonna show me I'm wrong now, right? You're gonna whip out some book or something and show me how what I've been doing all these years is wrong, right?" He laughed and shook his head. I didn't say anything. I just sat down at the computer and called up the heat loss calculation software. Ten minutes later, I'd sized the whole house for the heat loss on a 15-degree day. "The heat loss is forty thousand BTUH." I showed him where it said so, right there on the computer screen. "That can't be," he said, shaking his head with conviction. "Not with all that radiation you have." He shook some more. "It can't be. You'd never support the radiation with such a small boiler." "So in other words, you'd put in a boiler that's, what, about four times bigger than what the house actually needs?"
"But radiation isn't heat loss," I said, trying my best to convince him. "Your price is going to be out of line if you base your boiler size on the radiation." He just kept shaking his head. "Been doing it this way for years," he said. "I'm not about to change now. I'm not gonna put in something that's too small. I don't need headaches."

He waved his hand at the computer screen, dismissing it. "I don't need any of that," he said. "All I gotta do is match the radiation. That's all. I gotta support the radiation. I've been doing it that way for years."| Dan Holohan - [Intro] | [Email] | [Website] |
