4 Reasons Air in Your Heating System Can Be a Problem
As you probably already know, your home's radiators and heating system contain water that is heated in the boiler when you need to increase the temperature and keep yourself from getting chilly. Unfortunately, air can seep into the system over time, replacing the hot water. This can be down to anything from leaks to the natural contraction and expansion of metal over time. Luckily enough, you can have a plumber bleed the radiators to remove that air.
