Can boiler explode if pressure too high?
Can boiler explode if pressure too high?
High pressure is rarely the reason for a boiler explosion, but various other reasons such as faulty internal parts can cause it.
What should my Greenstar I water pressure be?
Greenstar i Troubleshooting If you have a combi or system boiler, which are both sealed systems, there is likely to be a water pressure gauge on the front. This should be at a setting of around 1 bar whilst the heating is off. When the boiler is operating, the gauge will usually rise to 1.5 bar or more.
What do I need to know about my Greenstar I boiler?
Ensure that there are no leaks to any underfloor pipework. Check that there is no water being discharged from the pressure relief valve (sometimes referred to as an overflow). This pipe usually goes from the boiler through to an outside wall and terminates outside. Check this for signs of dripping.
Where is the overflow valve on a GreenStar I boiler?
Check that there is no water being discharged from the pressure relief valve (sometimes referred to as an overflow). This pipe usually goes from the boiler through to an outside wall and terminates outside.
What should water pressure be on Greenstar I boiler?
When the boiler is operating, the gauge will usually rise to 1.5 bar or more. If the gauge has dropped below 1 bar, the water pressure will need to be topped up.
When to re pressurise a Worcester Bosch boiler?
However, when the boiler has been off for a while, the pressure is near enough back to zero after cooling right down which has forced me to re-pressurise to get the pressure back up to 1. I’ve been through this process a few times of re-pressurising when cold but then having to reduce the pressure when hot.
Check that there is no water being discharged from the pressure relief valve (sometimes referred to as an overflow). This pipe usually goes from the boiler through to an outside wall and terminates outside.
How is the pressure maintained in a Bosch boiler?
And the thingy that maintains this pressure is the E-V. Inside this tank (usually flattish, sometimes cylindrical – often coloured a dark matt red) is a rubber diaphragm with the system water on one side and air on the other. The air is pressurised usually via a normal ‘car-tyre’ Shrader valve.
