    I don't know if all of their manifolds have life-time warranties, but that alone would influence my choice of future products. They were ridiculously helpful and generous in reconditioning my...

    I'm looking a little closer at the nomograph now. First, it's mostly linear (I'd forgotten). That makes things pretty easy. The first thing you need to know is your heat flux, hopefully you already...

    No I've never seen the formula. It should only take a few steps to derive it from the graph, you just have to determine formulas for the various curves. How's your diff. eq's?

    Interesting point. But I believe the communication line still functions at or less than 60hz, and the skin effect is a feature of AC and a function of frequency. In which case the skin depth is over...

    I'm mostly familiar with the Fujitsus, but you'd just get an error code telling you as much and it wouldn't run, I believe. I could look up the error code. Same thing happens if you miswire the...

    Haha, I had a picture in my head and I didn't let go. It just sounded so ridiculous. Right, it was frost falling off the coil. That's funny.

    Had it right the first time. I wouldn't include an outdoor-reset mixer on the radiant loop unless (maybe) you're in a really extreme climate. Unnecessary complexity. The biggest value of the outdoor...

    Pmeunier has it right. Humidity can be evaluated as either absolute or relative, most of the time when we measure it we're measuring it as relative. Since warm air can carry more moisture than cold...

    Valves or pumps?

    If I understand, you are throttling your geo exchange loop down for your multiple geo units. Seems like you're overpumping your geo loop: if you have multi-speed pumps you could back them down,...
