PC water cooling pumps question?

[Bugsy_malone 666]

I was wondering how much heat can those PC water pumps actually take, I have in mind use for them in another application where the water may get a bit hotter than a PC (eg boiling water)

I'm trying to look for an inexpencive solution to a hot water pump for a project and PC ones fit the bill, just not sure about temps?

its case of what type of pressure your talking the system is going to hold ,remeber boiling builds up steam pressure,what is causing the heat an element' or is displacing heat from something else.need more input

ok well its actually a form of automotive heating system.

its a seperate system that will involve exhaust heating water and then the water being pumped to small radiators (no bigger than PC or possibly PC ones) to form a small heating system.

I figured using the PC components might prove useful because like the radiators are designed to get rid of maximum heat, thats great if you want warm air! plus the pumps being relatively low draw etc. Also becuase it uses relatively small pipe means it doesnt take up much room.

Heater matrix's !, thats what iwould be using bugsy& looking at washing machine pumps which are made to pump around hot water ,pond pumps are good i suppose

well the thing with a heat matrix is its size, PC radiators are tiny being just over 120mm square meaning they can conveniently fit anywhere.

The only problem with washing machine pumps is the fact they are 240volt.

The system will be running on 12 volt im not sure how good a pond pump would be for similar reasons, hence my initial thought of a PC cooling pump, its designed to run a system that has hot water in it and is also designed for continuos running.

There is the exact pump i require for the job in the automotive world already but cost is the main problem, I need low cost (hence the pc pump idea) I can see me ending up spending lots

am sure an inverter would cure the voltage problem bugsy

my 2p

1: How are you going to controll the heating of the water by the exhaust to prevent it getting too hot?
2: Electric coolant pumps are found on a few different vehicles, merc sprinters for instance, a scrap yard could have the right pump.
