Dry-Erase Markers and Central Heating

The fomer requires the latter to work properly. If a room is colder than about 60 °F (15.5 °C) dry erase markers cease to dry-erase so easily.

Since my home doesn’t have central heating (it has individual space heaters in each room), and I’ve been trying to live like the British used to prior to the 1970s (typically heat the main room in the home only), my home office is typically around 50 °F (10 °C) in the mornings (yes, British houses used to get colder than that in the old days during cold spells, but my place is of fairly recent construction and is thus well-insulated).

Why do that? First, it saves money. It also promotes comfort while outdoors, since the temperature difference is not so great. Most importantly, it reduces my ecological impact. And no, it’s not any great amount of suffering. Cold is why blankets and layers exist. Plus, the propane heater in my living room kicks out a fair amount of radiant heat, so if I’m on the couch in front if it, I can feel plenty warm even if the room is on the chilly side.
