The systems that actually generate heat are also worth looking at. Make sure that your boiler is serviced annually. This will help to ensure that you stay on the right side of your warranty, while
reducing the likelihood of a costly (and inconvenient) breakdown during winter. Since water expands slightly as it freezes,
cold weather can also cause pipes to burst.
Prevent this by cladding your pipework, particularly if it's running through a colder part of the home, like a loft space.
