indirect radiator

Better be careful, could be some kind of "Sainted" <i>burial ground</i>! :o<BR>If you mean 6"(inches), they likely just used those rooms to dump-it & help with dampness. Cinders was a very common "fill" in the day.<BR><BR>Dave

we replaced a steam boiler in a huge church .there are 50 radiators,and two cinderblockrooms in the basement that contain some indirect radiators. these rooms have 14' ductwork connecting to registers in the floor of the church.there are fresh are ducts connecting to these rooms. we are cleaning all of these ducts. my question is there is a layer of about 6' of ash cinders on the floors of these rooms.under the ash is a dirt floor. what is the purpose of this ash ? if any. and should we remove this ash ?

sorry I meant 6" of ash.

Sounds better,

if they are not used, and never going to concrete the floor, then I would just cover it up in plastic,, like a vapor barrier.

Could be the remains of the sinners back in the old days of the church when God still smote people. Sigh the good old days. I would say dampness control was the boring reason. Could also have just been a way the line the bottom of the coal bunker. Was the first heat coal?
