In a way the poles are the earths air conditioner (if you don't believe it, have a look at the climate in Tierra del Fuego, in South America and compare it to the climate in similar terrain in the northern hemisphere at the same latitude but north). Heat in the equatorial regions tends to migrate toward the poles, by some ocean currents (the Gulf Stream, for example), by weather patterns (Hurricanes, Typhoons), and by conduction in the water. If polar ice disappeared the most notable immediate effect would be a rise in sea level. Another effect would be that the interior of the land mass of Antarctica would rise above sea level (currently much of the land of Antarctica is below sea level due to the tremendous weight of the ice pack).
Personally, I think the most important effect will (or would) be that because of increased evaporation of the oceans due to warmer temperatures the cloud cover of the earth will increase (possibly bringing the temperature down). If it does increase, then precipitation may increase as well, and if some of this increased precipitation is snow in the polar latitudes a new ice age could begin.
To answer the actual question, heat isn't attracted, really, to anything. An object that is hot cools down because the heat is radiated away. The energy we call heat dissipates and the hot object eventually becomes the temperature of its surroundings (that is, unless energy is continually supplied); the hot object cools by heating up its environment. And, it works in reverse as well: cold objects warm to the temperature of their surroundings by absorbing the available heat until equilibrium is reached. So, I guess you could say that heat is attracted to cold, because SOMETHING is always absorbing heat from something else.

To answer your title question, let's understand just what heat is, ok?
Heat is quite simply what we measure when things have a lot of moving going on. Almost always, that motion is at the molecular level (vibrations). The more violently they are wiggling about, the higher the heat. Cold, on the other hand, is simply the slowing down of things that could wiggle.
The flow of heat is usually considered to be from high (hot) to low (cold) average kinetic energy.
Now, if we consider a time when there are no ice caps on the planet - and with all other factors are the same, like the composition of the atmosphere - then this planet will get warmer. It would be due to the decrease in "albedo" because those big, white snowy areas wouldn't be reflecting so much solar radiation back out into space. The relatively dark land remaining would soak up the sunlight.

As simple as I can make it:
"Heat" is the presence of energy,
"cold" is the absence of energy.
Energy tends to flow from high concentrations to low.
(The old saying - "Nature abhores a vacuum.")
This is called "Entropy" - Wiki it.
Even if "all ice is gone" , (Highly unlikely), there would still be considerable temperature difference
between the poles and equatorial regions because
angle of incoming sunlight dictates that the equator
gets a lot more heat per Sq. Meter than the poles.
The climate heat engine will continue to run.
