Boiler looses pressure slowly only when heating

2018-12-22 · OK, it’s indeed the PRV: When the boiler fires up and starts burning gas, a few table-spoons of water spurts out of the pipe, but there is no long term dripping as the water is driven around the central heating system. Secondly, the pressure rises by half a bar to 1.5 bars; so it would seem the pressure vessel also needs to be pressured.

Just because the boiler is running does not mean it is running to its full output capacity. I hope they did a proper start up and test for safety and efficiency items.

High-Pressure Cooker vs. Low-Pressure Cooker | Hunker

Pressure cookers are all the rage these days in home kitchens where cooking fast has become a necessity of busy family life. The way these cookers work is simple: A sealed pot filled with food and water allows steam pressure to build up inside, cooking the food quickly. You can turn a valve on the pot to control the steam’s pressure. High pressure is best for most dishes, but low pressure

If the boiler has dumped water outside though the pressure relief pipe then it’s likely that the pressure relief valve will need replacing, which is a very fiddly job on your boiler. You need a gas safe person to sort this.

Boiler (power generation) – Wikipedia

2019-11-16 · A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
