\"Creative\" venting

Ken C.

A potential new customer had our company over today for a quote on making his ancient boiler heat-worthy. I couldn't help but notice that the gas-fired hot water heater had 4" flexible dryer vent (aluminum) going into to the chimney. I asked him who installed the heater, but I already knew the answer (hint: the intitials are H.D.). Sleep tight, Homer.

I've seen that

A couple of times already. I've also seen z-flex liner run to the 3 ft long b-vent that went through the roof from the water heater 12 ft away. It looked like a camel

same matierial as chimney liners. it's ok as long as there is proper clearance to combustables and pitched

Same Material?

Product sold as a Chimney Liner is backed by the manufacturer, and is Listed by a recognized agency, for its intended application. Criteria imposed for Listing include thickness of material, permissable alloys, joint/lock design, bend radius, puncture resistance, thermal performance and adaptablility to appliance flues. Don't believe you have the same backing if you use dryer vent as a combustion vent.

same material??

umm....I hope the liner doesn't have that horrible seam that unzips if you look at it wrong...

Aren't chimney liners SS not aluminum?

MATERIAL

Gas uses aluminim liners while oil uses SS liners.
Neither use dryer vent.......;0)

right.....

Sure it's the same material, ALUMINUM. The "sameness" ends at 1/2 the wall thickness and NO approval for this application. When was the last time your Dryer vented at 450F ? I'm betting your wife would howl about THAT shrinkage !

curiousity kills

I saw home HD install hydronic expansion tanks on domestic line to water heater on three occassions.
