But all Icn say is when the temp gets down to tho single digits the house cools down. even though the water temp going out through the loops is up, I tweak it with the mixing valve, it just seems like it is not enough.
First question - When it is cold outside and the house is not maintaining the temperature you want...what is the KAA-2 temperature?
Second question - What temperature water are you running through the radiant system?

Larry, up here it isn't uncommon for a radiant floor to not be sufficient if the room has a lot of glass, or a lot of wind exposure. A few feet of baseboard and a two-stage thermostat go a long way to maintain temperature in frigid weather.
