Heat from heating pipe?

Hi there,
is it possible to derivate the heat of the heating pipe of an heater to make a water circle (with a pump) to create ones own heater?
Because i feel the heating pipe is extremely hot and it's heat for free, so why not using it?
The idea is to build something like a water cooling system for the PC but just without the cooling.
Can i wrap a cooper pipe around the heating pipe and let water circle with a pump, so the hot water  passes through the "new heater". I dont know what to use as heating object but there will be a way.

Any ideas? Is it even possible?

Thank you and sorry for my English :D

What heating pipe are you referring too? Are you talking about the hot water pipe coming off of a hot water heater?

Older heating systems used a furnace that heater water to steam and ran that stream through pipes to radiators around the building to heat the various rooms. Many in floor radiant heating systems use hot water from your hot water heater circulating through pipes to heat the flooring.

If your wanting to use a hot water pipe for heating all you have to do is ad a radiator inline withe the pipe. Or you can add your own fins to the existing copper pipe (assuming you have copper pipe). Any radiator you can find that has the right fittings will work. Even a radiator from a PC water cooling system will work. All a radiator consists of is some aluminum or copper pipe with thin aluminum or copper fins soldered to it to help dissipate the heat into the air.

EDIT: Because this part of the pipe is always hot, not only if the heater is turned on, I try to hold the bills low by grabing the heat from there, which is always present and make this little system work for the whole room
If you want to help save on your heating bill then your better off wrapping the exposed pipes with some good insulation so more of the heat is going into the radiator where it can be better distributed throughout the room.

But what if I dont want to turn on the heater and only heat the room with this system? Is it possible?
Does that radiator have a fan on it or something that you have to turn on, or just a valve to allow the hot water/steam to flow into it?

I have two ideas for the radiator. The first is to bend a long copper pipe (like in my professional made picture :) ) and put it into a aluminium case to reflect some heat into the room.

The second idea is to use a car engine cooler. I dont know what it is in english, but you know just something like this:

Till now, I am searching for more possible radiators.
