You trust your boiler to supply a constant flow of heat throughout your home. It keeps you and your family cozy when outdoor weather chills the bones. Did you know you can return the favor by ensuring your boiler has the right pressure level?
What is the correct pressure for a boiler, anyway? Green Energy Mechanical Inc. provides experienced boiler installations to Wapole and can teach you about boiler pressure. Make us your first call for HVAC services, and keep reading to understand how your boiler works.
Why Boiler Pressure Is Important
Boilers are popular HVAC appliances among homeowners who want consistent, even heating without dry, uncomfortable air circulating throughout their houses. A boiler typically heats water until it steams. Once the water reaches the right temperature, the boiler uses pressure to circulate the steam or water throughout its pipe network.
Pressure is essential to heating your home with one of these systems. A lack of pressure prevents the heat from flowing effectively through the pipes. Too much pressure may result in dangerous consequences, including explosions.
What Is the Correct Pressure for a Boiler?
So, what is the correct pressure for a boiler? Most HVAC technicians measure pressure levels in pounds per square inch. The PSI determines the pressure’s weight upon its supporting surface. The correct pressure levels for most boilers range between 12 and 30 PSI.
However, you should treat this number as an estimate. Different appliances have varying PSI they can handle. Check your user manual or the manufacturer’s website for your boiler’s ideal pressure level.
What Do Incorrect Pressure Levels Do?
When your boiler’s PSI reading exceeds or falls short of its recommended pressure level, it can cause disastrous consequences. Most modern boilers come equipped with safety features that prevent dangerous circumstances from occurring. However, they can still develop significant issues without their usual pressure levels.
High-Pressure Concerns
The average boiler has a maximum PSI it can safely reach before its safety mechanisms trigger a shutdown. This tipping point is usually around 30 PSI. However, pressure levels vary depending on the model used.
Once high pressure triggers the sensors, they cut the boiler’s power supply. The pressure valve may also release some of the built-up force stored within the boiler. You might notice your indoor temperatures dipping below your thermostat settings as a result.
While these safety features will usually prevent further issues, they can still fail in rare circumstances. A safety system’s failure sometimes results in a boiler explosion. The extreme force from an explosion will destroy every structure within the boiler’s immediate area.
Low-Pressure Concerns
When the pressure dips below sub-par levels, it has aggravating but less hazardous consequences:
- Unheated home: Your boiler might fail to keep your home heated. You’ll notice a gradual temperature drop throughout the building. Button up your favorite housecoat and call a skilled HVAC technician.
- Uneven heating: Sometimes, the boiler has just enough pressure to keep nearby areas warm. However, the water or steam fails to reach areas further away. Therefore, you might notice significant temperature differences between the two halves of your house.
- Low hot water supply: Lukewarm or cold water might greet you after turning the hot water faucet on. Your boiler might prioritize other heating systems when it doesn’t have the pressure it needs.
Fortunately, you can prevent fluctuating pressure levels with some professional assistance and proactive maintenance habits.
Maintaining Optimal Pressure Levels
What should you do to ensure optimal boiler performance? Most HVAC professionals recommend regular maintenance from professionals and consistent self-inspections.
Annual Boiler Maintenance
Before turning your boiler on for the winter, schedule a maintenance service from your preferred HVAC company. Your technician will inspect and troubleshoot your appliance to ensure it will perform reliably throughout the winter. They’ll discuss any concerning findings with you, suggesting repairs that will improve your boiler’s overall performance.
Monthly PSI Checks
Most boilers have pressure gauges located near the top of the appliance or around a valve. Your owner’s manual should have a diagram of your appliance’s parts enclosed. Each month, remember to check the pressure gauge. The gauge should have a green triangle signifying optimal pressure levels. Call a trusted local HVAC company if the gauge’s hand falls anywhere above or below this marker.
