What happens if you lose pressure on your boiler?

Boilers require pressure to be maintained within a certain range since it allows the hot water to circulate around your system. A loss of pressure will result in an inadequate amount of water running through your boiler that will, in turn, struggle to provide heat to your home – or enough hot water, obviously.
