91° outdoor today so I put the VitoCal A2WHP in cooling mode this week. I'll give it overnight to bring the slab ° down.

    is it dry enough that you won't have a swamp tomorrow?

    Really interesting @hot_rod, we're running a similar trial in our showroom in London. We've been keeping the flow temp just above dew point. It has had a modest cooling effect but the ∆T is so small between ambient and water temp that the we're talking a degree or two of cooling effect. We'd need to add condensate drains and chill the water further, and introduce fans to move the air around in order to get more siginificant cooling.

    Would love to hear how you're getting on a month on. Has it had a significant effect? What were the ambient, flow and return temps? What emitters are you using? Is this a radiant floor?

    usually they do radiant cooling in large buildings where they duct in ventilation air and that ventilation air is already dehumidified.

    or move to the desert like @hot_rod

    I used to watch a movie as a kid where they show what I thought was supposed to be an alien facility on Mars.

    I found out recently, no, that's not Mars, that's just Utah and that's actually how it looks. Dusty.....dry..

    Very different from anything I've ever known which is usually very hot and humid. Our dew points have been 70-80f lately.
