under the sea (t)

It's like that, to muffle the racket coming from the rattling tappets and general engine noise. it does not restrict the warm air flow.
If the wadding is missing, it will leak warm air under the seat, which is useless unless you have passengers who like that sort of thing. You can raid that kind of felt wadding from under the carpets of almost any car in a scrapyard, but anything is better than nowt.

not heatproof then?

it doesnt get so hot that it will set my shit aflame?

ive already set fire to the backseat once, kneeling on the battery terminals through the seat with no battery cover.......oh, the shame....melted one of my springs right off....

and why the perforations in the Y tube? if its just for noise reduction?

why is life so complicated?

Beetle heater does not get hot enough to burn the felt.
Perforations work just like the innards of an Exhaust silencer.

A rubber car floor mat solves that problem every time

Or some polythene sheet over the battery, Infact get it mostly in a plastic bag, keeps it from leaking and shorting out!

The heater under the rear seat in my splitty melted my sandle once, if they are working well it belts out some heat I can tell you. THe heating in my splitty has people complaining that its too hot in there. I ve insulated all the pipes with potato sacks all the way along theres no gaps in the doors to let it escape nor in the pipes.

So it can be good!

looking at it the other way... its a real shame more hot air doesn't leak out of the pipes - especially along the heater channels. It would have kept mine dry and they wouldn't have rotted out :crazy:

im drilling 15mm holes all along mine then!
