    Anyone else approaching Design Temperature Tonight?

    Design Temp is -5*F in this part of upstate NY. That's the low tonight. Tomorrow night calls for ... -17*F! Woohoo! Warms up Friday night to -3*F

    Thursday Day does have a high of 9. So that will be nice.

    So who else is approaching/exceeding Design temp this week?

    I use a 6 degree WDT....and yes, we will be going below that. They may cycle a little more often, but Im not expecting any issues with maintaining an indoor temp of 70 degrees.

    We hit 0 degrees this morning, no problems noted. Thermostat set to 68
    space load 49311 btu/hr GeoAir 47,445 BTU/hr at 2deg , 1500sqft, ceilings rated
    U.07915, the sides and windows have been upgraded so am not sure of their ratings, my design studio report shows support to -18 degrees, I have not seen
    it that low in many many years and the ASHRAE report used for designing our
    geo only shows 1 hour in the past 20 yrs, this is for Grand Rapids, Mi. My design report shows that we lose 6277 BTH/h at -3F
    Our system is designed so that emergency heat will only come on with owners setting of the thermostat to emergency heat, otherwise with the lower temps
    it runs at half power and cylcles with 6 min off but runs at 100% at temps below 17 degrees. So far our system has tracked the design specs very well and most areas are at 70F degs.

    I've traveled to the great city of Aberdeen SD for the week.
    Tonight's low is supposed to be -30, right now it's around -15, supposed to get to -8 though...heat wave!

    Wonder if they'd be mad if I left my van running all night? lol

    The ASHRAE 99% design temp for my area is 43ºF which is what is forecast as a low for the next four days.

    I may even get to see my heat pump actually go through a defrost cycle.

    I probably am (furnace is firing more and more), but I'm still trying to figure out what my design temp is!

    I think we're near ours. It's 4*F here. I think DT in Des Moines is-5 . Anyone know?

    But I do know that we're heading toward -17 tonight, and then some wind--or else it would get even colder.
    It's great to be alive and pumping oxygen!
