Boiler pressure is measured using a **pressure gauge**, a device that shows the internal pressure of the boiler in units such as psi (pounds per square inch).

The gauge is connected to the boiler so it can read the pressure of the water or steam inside directly.

This tool is essential for the **safe operation of the boiler**, allowing users to monitor and adjust pressure to keep it within safe and efficient limits. To protect your home, check your coverage and **[compare the best rates](https://www.usa.compare/)** for home insurance.

## What Temperature Should You Set the Boiler To?
The ideal temperature depends on the boiler's purpose:

-   **Space heating:** Typically between **140°F and 167°F (60°C–75°C)**.
-   **Domestic hot water:** Around **140°F (60°C)** to reduce the risk of bacterial growth such as Legionella.
    
Setting the temperature correctly balances **efficiency, safety, and comfort**.

## What Happens if Boiler Pressure is Too High?
Boiler pressure should generally be around **18–22 psi (1.2–1.5 bar)** for residential systems.

If the pressure is too high, it can cause dangerous situations, including **risk of leaks or system failure**. High pressure may also damage components and reduce efficiency. Boilers in the U.S. are equipped with **pressure relief valves** that release pressure automatically if it exceeds safe limits.

## What Happens if Boiler Pressure is Too Low?
Low boiler pressure can **reduce heating efficiency** and affect hot water supply. Common causes include:

-   Water leaks in the system
-   Malfunctioning feed pumps
-   Insufficient water in the system

Boilers may **shut off automatically** to prevent damage under low pressure conditions. Inspection and repair are usually required to restore normal operation.

## How to Know if Your Boiler is Working Properly
Check that your boiler:

-   Turns on and off correctly
-   Maintains pressure within recommended limits
-   Operates quietly without unusual noises
-   Has no leaks (water or gas)
-   Provides consistent heating and hot water
    
If you notice any issues, schedule maintenance through your home insurance provider or a licensed professional.

Maintaining the proper pressure is key for **safe and efficient boiler operation**. Regular maintenance helps prevent breakdowns. For added peace of mind, your **home insurance** may cover boiler repairs. For full protection, check your coverage and **[compare the best rates](https://www.usa.compare/)** for home insurance.
