Hot water lines crackling

@ November 2, 2008 7:50 AM in Hot water lines crackling

I seem to get a crackling sound coming from my hot water supply line, it seems to be coming from either a tee fitting or a elbow. i think it is some air bubbles trapped, any comments

Thanks kpc, i will most likely go with a extruded insulation with a vapor barrier on top of the pea gravel.

one of my concerns with the drain back system is the shock to the collection panels when a tepid liguid suddenly hits a panel that is very hot

Can anyone explain the pros and cons of a drain back solar system, as opposed to a system that is charged with Glycol. I am getting quotes on both systems and not sure which way to go.

I have heard of Double Bubble that i have been told has a higher R value than the extruded board with a white poly wrap on one side to contact the cement and foil to face towards the ground, i have been told when the foil faces the concrete it will react with the caustics in the portland which will desolve the foil face. Has anyone had this experience

When installing radiant tube under a concrete floor is it necessary to lay a layer of extruded polystyrene insulation on top of the pea gravel then laying the tube on the insulation prior to the concrete being poured.

Mark, i should have spell checked before sending Tim

Thanks Mark for the response, i will contact you, as far as rhe condensate drain, it is well drained w/ 1/2" tube approx 3'-0" to a recessed floor drain, so i don't think trapped water is a problem it has also been mentioned to have a loop installed to prevent exhaust gasses from being blown into the buiding, could it be possible with the vent termination kit, that hot exhaust gas is being trapped or not being pushed by the pump significantly enough to over come some wind turbulence on the roof. Could we also extend the exhaust opening on the vent termination kit another maybe 2'-0" or so to overcome the hot exhaust gasses possibly rentering the make up air opening. Tim

Bradford White water heaters

@ May 23, 2006 3:35 PM in water heaters

We have been installing Bradford White EF 100-199E with an Eccentric vent termination kit venting directly straight up through the roof ( approx. 15'0") well within specs. we are getting quite a bit of condensation buildup in the flue pipe that it is causing the pressure switch to fill up and or cut out due to excessive moisture. Of course the Manufacturer can not give us any help. Does anyone out there have any experience with these water heaters and this problem. Tim

Ed, the expantion tank is a small Watts I believe, the air seperator is a B&G lacated on the make up connection, and it is in floor radiant with Wirsbo Tube and manifolds, i have a 3 loop manifold in my closet that seems to be closest to the sound but when i bleed water from the hose connection i don't get any air pockets flushing out.

Crackling in hot water heat system

@ December 4, 2002 7:36 AM in crackling in hot water heat system

we have hot water heat in our home and i am getting a crackling sound in a set of supply and return risers, i would suspect it is trapped air rolling around, i,ve tried flushing from my upstairs manifold but doesn't seem to help. Any ideas are welcome, Thanks,Tim
