Heat = Quickest way to pack a tube.

Heat plus stretching and jelqing has a well reported success rate but the amount of guys who report gains from pumping only even with heat is insignificant.
It only seems to work well when combined with other things.
If your routine is working then great :)

My reaction exactly. Once you go with the heat you never go back!

I am mixing clamping with pumping with heat and have seen much more expansion than just pumping.

And sensitivity.

Do the plastic tubes do ok with the heat?

My Thickwall Cylinder is made from cast acrylic. Cast acrylic has properties that make it suitable for a wide variety of applications.

Thermal Properties:
Minimum Service Temperature -40⁰C
Maximum Service Temperature 80⁰C
Softening Point > 110⁰C

I’ve had no problems with my cylinder, and it gets very hot on the outside. :)

I do a two stage heating routine these days. 10 minutes with the IR lamp and then the rest with the heat mat wrapped around my tube. Seems to make a difference, when I don’t IR heat, my pumped length is almost 1cm shorter.

I must get one of those electric heat pads, I’ve had great pumping sessions with my regular heat pad but I’m getting tired of putting it in the microwave every time. So what are the best brands in your opinion? The ones where you can set the temperature are just what I need.

Water pumping with warm / hot water… just sayin.

Theoretically that is best, the wet heat application seems to work so much better. In practice though water pumping is just too time consuming to set up (for me).

Bathmate. Use it every time you shower.

Heh I have wrapped my thickwall with a heating pad and when I come out of the tube I get a bad smell of plastic or so not massively pungent.. So not to keen on the idea of wrapping the cylinder anymore.. Even though I’m sure its helpful for loosening things up and gaining

If I put on the electric heating pad and warm the tube while I slowly bring up the vacuum, I notice that there is no pain from the heat and I wonder if I may be getting too hot. When I grab the bare tube it is hot but there is no pain. If I preheat the tube and enter after the tube has reached a similar temp it really stings and I have to let it cool. Can’t enter otherwise.

I guess my question is, can I be cooking my cock and not realize it because of the gradual heat increase vs sudden shock? I haven’t gotten blisters or anything outside of some very small red spots and overall darkening discoloration that others report. Is there anything else to look for? I am guessing this has been discussed but searching “too hot” or “too much heat” didn’t bring up any unique searches. Most searches will mention heat.

Yup hot water pumping . As hot as u can stand. Get in the tub and then start the water. Your body can get use to the hot water faster as you fill. I made a water separator out of a ball jar to put inline with my electric vacuum pump and a filter so no water vapor can get back to my pump. 15 min in tub with hot water in tube and around it. IR light after to keep things warm when I get out. Big gains but be careful of what u r doing.

I agree with heat. I like taking my normal air pump and tube into the shower filling with hot water. It feels great and seems to work better.

Can you guys post what heating pad you use? And what is the wattage?
