Reply to comment by SasquatchGroomer in Is it normal for the heat to not be able to keep up with extreme cold? by SquashDue502

Furnaces only have on or off, they don't work harder to maintain in set temp, they run longer. Heat pump systems are a different story but the furnace or boiler found in most homes just runs longer to get to a higher temp.

Often the limiting factor is the distribution of the heat to the living space (ie HW baseboards). Also, some newer modulating condensing boilers can adjust up and down.

Yea that probably don’t have enough linear feet of baseboard and given that it’s a rental it’s probably poorly insulated.
