Kindly rephrase the question for more clarity. It looks like you want to use an electric 600 watt radiator heater. Please, DO NOT ATTEMPT THIS DUMB STUNT. How much do you value your life or that of your family. I hope you have very good insurance coverage. Electricity and water do not mix well.
The use of a bubble solar blanket would be far less costly in terms of lives lost.

Disregard Ken's answer above. No, an inline radiator heater is a 120 volt device, designed to heat about 3 gallons of coolent. A 4,400 gallon pool would not be effected much at all by a radiator heater. You need a pool heater designed for that purpose.
To keep the car engine from over heating
It varies depending on your year, make, model, and engine size.
It can. You should leave the engine running while you add water to the radiator. If you add water with the engine turned off, but while the engine is overheated, you might damage the engine or the radiator.
Top hose of radiator is hot and engine is still over heating usually.
The heat shield on the engine is located on the front of the engine over the exhaust manifold. It is on top of the engine just behind the radiator.
That is the fan cooling the liquid in the radiator to keep the engine from over heating.
While your car is running the engine is heating up. While your driving you have air being forced over the radiator cooling it off. When you are sitting still you don't have that air so your engine is heating up even more so the cooling fan comes on to help cool you engine off. Via cooling the radiator.
I highly doubt it, a radiatior keeps your car from over heating so no radiator and your engine might explode. The early Volkswagon beetles were air cooled, no radiator.
have your radiator cleaned and replace your thermostate, clogged radiators and sticky thermostats can cause your engine to overheat under load.
yes if the dust has stuck to radiator,and blocked the cooling fins, it will sure enuff cause over heating. with engine off, you can usually wash dust and other debri out of radiator fins from the engine side, using a hose.do not use a pressure washer as this will damage the fins
No, you do not have to remove the engine to replace a radiator hose.No, you do not have to remove the engine to replace a radiator hose.
What I did was let the engine cool down then open the radiator cap and turn on the engine. Let the engine idle for about 10-15 min to make sure it had circulated the coolant. Between those 15 min you should see bubbles and that's bleeding the radiator you're removing the air, and this is how I did it because after a radiator flush I left the engine off when I poured the new antifreeze and it was over heating but now that a let the air out it's much better.
