Some tips to help you avoid frozen pipes.
Make sure to service your heating system annually.
Keep the proper level of water in the system, especially if you are going to be away. One option to consider is an auto-filler on your steam boiler.
If you have pipes that run adjacent to exterior walls, set the temperature on your thermostat a bit higher than normal during a cold snap. A few more dollars to the utility company is still cheaper than a burst pipe.
Turn on the bathroom heater fan if you have one.
Open lower cabinet doors in kitchens and bathrooms to allow warm airflow to the pipes behind them.
Let a small flow of water drip from faucets if the temperatures are going to be below freezing.
Insulate around any pipes and block any airflow from the cold exterior.
If the toilet fill supply line is on an exterior wall, you can place a string under the flapper so that the tank fills slowly with water to keep ice from forming.
Monitor the temperature in your house if you are away with a smart thermostat like Nest.
