The volume of solid ice is greater than the volume of water. In winter in the absence of heat water in the pipe freezes, as ice takes greater space to fit in than water, the pipe burst in winter in the absence of heating.

Freezing of water is an exothermic process (heat is released by the system into the surrounding) where as melting of ice is an endothermic process (heat is absorbed by the system from the surrounding). If the heat was on it would prevent ice formation in the pipes.

The water pipes burst due to the expansion of water in them.

Water behaves in an anomalous manner. While most substances expand when heated and contract when cooled, water begins to expand at 4°C.

As a result of this, solid water is less dense than liquid water because it has more volume than liquid water.

Since solid water has more volume compared to liquid water, the pipes may no longer be able to contain the expanding water which has turned to ice leading to the bursting of the water pipes.
