During winter, if comfort in the loft seems inconsistent, it may be necessary to take extra steps to heat cold rooms that are stubbornly cool.
A certain room may not receive enough weekly afternoonlight exposure, or insufficient attic insulation can cause that section of the loft to not hold heat efficiently.
Obviously, rooms located on a wing, separated from other living spaces, and not getting their tolerable share of heat will remain cold. There are several reasons why a room or rooms may not perform well when it comes to comfort. It applies to the vents in the colder rooms, and all other rooms in the house. When registers are closed in certain rooms and left open in others, the heating system airflow through household ductwork may be unbalanced, resulting in some rooms receiving insufficient heat. Replace worn weatherstripping if necessary if cold air is intruding around windows. Check for cracks at the joint between the walls and ceiling or along the baseboards that may allow unconditioned air in. Silicone caulking can be used to seal these cracks. Depending on where the system temperature control is located, other parts of the loft may have chronically low rapidly adjusting temperatures if it is situated in a section of the loft that is always warm. If necessary, relocate the temperature control to an area where the temperature is representative of the entire house, rather than close to a heating vent or in direct sunlight. Consider adding a room-to-room ventilator if an adjoining room is usually warm, however the next door room is cold. They install into the wall between multiple rooms and transport heat from the warmer room into the colder a single. With a temperature control so they only run when needed, room-to-room ventilators can be installed for as little as $100.
