What does bleeding the radiators mean?
Radiators work using a hot water circuit that moves inside them. To be fully efficient, they need the hot water to circulate and no “air bubbles” to be produced in the circuit.
However, it’s quite common for a little air to leak into the circuit and, therefore, their efficiency decreases and they don't emit heat evenly.
Bleeding a radiator is nothing more than extracting those air bubbles to optimise circulation in the water circuit and make it work more efficiently. In other words, removing the excess air from the radiator circuit to improve the energy efficiency of the heating system.
This is very important. We must ensure that our heating system works properly. An efficient heating system will save you energy and, therefore, save you money on your bills by reducing consumption.
