No need for insulation, just add more radiators

Dennis

While touring the Golden Mile, a stones throw from The World's End in Edinburg, Scotland I spied these cast iron radiators in a former church, now a museum.

I've seen those... adding insulation to a building that age and construction is a bit problematic...

And, of course, when that building was built, central heating meant that the fire was in the middle of the room!

That is where you would want to sit in the church.
Serious EDR for serious tons of masonry to heat up.

Hi, I’m guessing they didn’t keep it warm all the time, so likely had to heat a cold, stone building quickly. Some pretty serious setback!

Yours, Larry

They don't keep it exactly what we'd call "warm", either, @Larry Weingarten . The building my daughter lived in for a few years -- not far up High Street towards the Castle from this one, in the Lawnmarket -- was heated to a sweltering 50 or so (Fahrenheit). Of course, it had been built around 1500...
