Water flow

I think if your aquarium water temp is hot enough to melt PVC, you most likely are gonna find dead rays in the tank already.

Thumbs up to that

I dont think you understand how a heater works......... The heater turns on and gets much hotter than the water temp in order to heat it quickly. Then it turns off until the water cools again. Hence the reason rays get burned when they touch the heater but not burned by the actual water temp.


This is why im concerned with the pvc melting. The pvc is in direct contact with the heater the entire time so it will be far hotter than the water.

Ever check the melting point for PVC? If the PVC could get that hot to the point of melting, I don't think the rays would stand a chance in the water.

ok you are still not getting it. the entire tank does not heat to the same temp all at once. the water and pvc immediately surrounding the heater will be hot but entire tank temp will raise gradually. therefore the pvc could get very hot in the brief time that the heater is on while the rest of the tank is quite comfortable for the ray. this is really a basic concept.

similar to global warming? its hot as balls in phoenix but still very cool in greenland. however the overall temp of the planet is slowly rising.

Had a 250watt jager in a 3 inch pvc pipe drilled with lots of 3/8 holes with a fx5 pointing at it so it got good flow for over a year at 82 degrees. No melting at all.

How many Watts is your heater?

Because for most aquarium heaters, at no one point in your aquarium will be heated up to 100–260 °C (m.p of PVC) which is also the b.p of water, not even at the source of the heat. Else you would have seen bubbles coming out from the heater already.

Unless you are telling me you are running a heat exchanger or a house oil fired hot water tank.

I built an in-line heater assembly for my tank out of PVC. As long as there is some flow, you don't have to worry about it overheating. Yes, the heater will get a bit hotter than the water, but any major increase will disperse throughout the aquarium with just the flow of the filters. You should be fine.

if the pvc is from the diy store then its most likely designed for use as overflow pipe or to carry electrical cables , in either case they are designed to withstand very high temperatures and as such, i seriously doubt boiling water would affect it .
