    water to water?

    But what I want to know is: when will we see the water to water version? I find it curious that water to air is always front & centre and the water to water units always seem to be an afterthought, even though most new houses I've seen in the past 5 years have some form of hydronic heating in them. Unless my area is just an anomaly and the US air conditioning market is driving all the latest technology.. oh wait, it is.

    zac in my AO most of our business is retrofit, so we are connecting to existing delivery systems. WTW for us is about 1 in 50.
    With Climatemaster however, their last big product intro was WTW as far as new equipment- THN

    Sorry Zac I didn't percieve a reduced efficiency mid grade model as a "big product intro"; sort of a step back....

    Sorry Zac, I gues I was thinking in terms of "breakthrough" but I did write "intro".:eek:

    I heard today that run time will about double, but consumption of circulations pumps will go down by more than 90%.

    pumping

    Yes, I would be surprised if it didn't have an internal variable speed ECM loop pump, I get the feeling that will be the norm now, it is on most euro units.
