Foam insulation on furnace/heat pipes - good or bad ?
I am trying to save heat/ energy/ money.
I have 51 year old ranch house - just ok insulated and original natural gas furnace here in Arlington MA. With castiron
radiators around the house. The house stays pretty warm all
season for 50 years.
I wrapped up the basement cellar water radiator/furnace pipes in Frostking foam -
Will this indirectly hurt/damage/strain the furnace heater
by keeping the 1 1/2 " pipes coming out and going out to the
cast iron radiators upstairs by keeping the pipes so hot all the time ?
What about the red water circulator pump ? Will putting foam insulator on pipes in cellar hurt/cause pump to run more or less or maybe damage it ?
It sorta seems like I have to turn up the thermostat a little bit more now to get the usual warmth upstairs.
I figured the old furnace should have to work less now - but now I'm not so sure ...
Did I actually make upstairs colder/worse since before the pipes just naturally radiated their excess heat out and up (to the ceiling/upstairs above anyhow) ??
Thanks alot... trying to keep warm this soooo Colddd winterrrr
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 ?
