Why Is My Boiler Leaking Water? | Vaillant

Hot water heating systems are built around the premise of radiant heat. Water is heated by a boiler and circulated throughout a building--usually homes (older homes, especially)--through a series of pipes that heat radiators that give off heat. The heat transfers to the air in the room.

Boiler pressure dropping when heating is on

Kefid · But I noticed that if the heating isn't on and we just use the hot water, then there isn't a drop in pressure (or if there is, it isn't noticeable). So it is either a leak in the system, which gets worse when the hot water is pumped through, or there is an issue with the boiler such that when the heating is on, the pressure reduces?
