Morning heat problem

mraia

Good morning. First timer here. I have 2 zone gas heat. We're in NY and are having -5 temps. I have my thermostat set to a constant 73. The reason it's so high is that we have an open floor plan and our main living room is a four seasons ,all glass sun room. It has baseboards, but is always colder than the rest of the house. Anyway, why is the temp at 67 this morning? Shouldn't the temp be 73 all day and night?
Thanks for the help and stay warm!

understand that depending on you location heating systems are designed for a certain design temperature, for example in my area we use 0 degrees. yet around here our temps have been colder than that. that means the inside temperature will "slip" downwards.

What your experiencing is normal. A few things you might check/do.

Weather stripping around doors
good windows
add insulation
Keep furnature away from baseboards & heaters
Keep baseboard fins clean

Have your system serviced every year.

Like I said we are having abnormally low outside temperatures. It's going to warm up tomorrow

Thanks very much! As long as it's relatively normal I can certainly live with it.

Remember this , The very best window is still a sh*^%y wall

That space is simply falling behind. You are probably 10f colder than design and depending on wind, shading, sun, air leaks you’ll be even deeper “ in the hole”.

Is the boiler running continuously or cycling on and off? Might be able re-balance the system to more heat goes to the room with that’s cooling off. Or do you mean that entire area or the whole house is 67f?

I see you probably have forced air furnaces. If it’s like most every home I’ve owned, the ductwork is poorly laid out and it’s unbalanced and worse the furnace is oversized (90% of homes are) so shorter cycles make it even more uneven.
