Pressure Reducing Valves (automatic water feeder valves

If you set the boiler water pressure too high when cold then when the boiler heats up the pressure will exceed the (roughly 30 psi) pressure at which the relief valve will open. But a more likely reason this valve was tied OFF or CLOSED was that it was leaking, feeding excess water pressure to the boiler on its own.

Why Is My Boiler Making Noise? | Boiler Kettling | Vaillant

Humming boiler noises can be created if water arrives from the mains at too high a pressure. This can cause valves in the boiler or around a home's pipes to hum. A humming noise can also be caused by a pump sending heated water around the pipework too quickly, or by the bearings in the boiler fan humming as it moves.

Boiler Noises And What They Mean | Hometree

It's pretty safe to assume that this noise is caused by either kettling or trapped air inside the central heating system. First, try to bleed your radiators to remove the air.. This is a very easy process and doesn't need an engineer call-out, but don't forget to check and adjust your boiler's pressure afterwards.. If you've bled your radiators but the noise persists, kettling could be

Why Does My Boiler Make A Banging Noise When Firing Up

When a very large boiler makes loud banging noises, you're right to be concerned. So what's causing that noise and is it dangerous? Well, it depends: If your boiler makes a single BANG only when it fires up, it's most likely due to delayed ignition.

Boiler Losing Pressure? Here's Why and What You Need to

Jun 04, 2021 · The speed at which your boiler loses pressure determines how bad the new leak is. So, if your boiler is losing pressure slowly (i.e. you can't visibly see the dial going down, but pressure goes down overnight), the leak is small. If you can visibly see the pressure gauge going down, your boiler is losing pressure quickly, and the leak is big.

Boiler - Wikipedia

As a superheated boiler is usually operated at high pressure, the corresponding feedwater pressure must be even higher, demanding a more robust pump design. Another consideration is safety. High pressure, superheated steam can be extremely dangerous if it unintentionally escapes.
