Re: Foam insulation on furnace/heat pipes - good or bad ?
I'm no expert as to boilers and the related components ... however..... insulating the delivery pipes shouldn't cause any strain on the equipment.
There are 2 schools of thought here.
the pipes just naturally radiated their excess heat out and up (to the ceiling/upstairs above anyhow) ??
One thinking is to insulate all pipes ..... in the case of forced air insulate the ducting .
The reasoning is to minimize the heat loss from the hot water or hot air to maximize it's intended use.
The other thinking is whatever radiated heat loss that does escape from the pipes or ducting within the conditioned space is considered a positive net gain ..... since this heat goes toward heating the home.
In the case of forced air heat the ducting would be sealed for air loss .... we are talking about the radiated heat from the metal ducting.
This would be different if the pipes or ducts were run through an uninsulated crawl space or garage .... which case the heat loss from those would be a negative.
On one hand it may be possible you experience what appears to be cooler temps within the living space ... the basement for example .... by insulating the pipes or ducting since they aren't contributing with the radiated heat.
yep .... won't hurt.
PS... I also put the foam wrap on the hot water 3/4" pipes in cellar too. That should help at least with hot water for sinks and showers, right ?
Just a thought.
