Or what will the maximum pressure in the geyser go up to if you start with 3 bar or 3.5 bar etc.?

If you pump a geyser (water heater) full of water at ground temperature, let's say 10 degrees C, with a pump that switches off at 4 bar max, what happens to the 4 bar pressure in the geyser when you heat the water in the geyser to let's say 80 degrees C? What I need to know exactly is the following

(Brandford White 2019) Question: How much does pressure increase inside a water heater tank (geyser) as the temperature rises? The result can be a dripping temperature/pressure relief valve that can in turn become clogged, rendering the water heating system unsafe, damaging the water heater tank, or even leading to an explosion.Īs the temperature increases, the maximum working pressure for which the water heater was designed (150 PSI) can be exceeded. Watch out: But where there is an obstruction to that expansion, such as by a backflow preventer or check valve, pressure in the system will increase. The actual or observed water pressure increase in a water heater as the water temperature is raised could be very little, even zero psi if the water heater is connected to open plumbing system, as the expanding water simply pushes back up the cold water lines into the cold water supply. Obstructions include check valves, backflow preventers, some water meters with a built-in backflow preventer, and in some buildings, the presence of a water softener. What makes a plumbing system closed or water-solid? That's a 65 psi increase occurring from a 16☏ temperature increase, or roughly 4 psi increase for every 1☏ of temperature increase. Hot water pressure increase in a water heaterĪ 40 gallon water heater with 80 PSI line pressure will build to a pressure of 145 PSI with a temperature increase of 16☏. And finally, our friends over at remind us that calculating the cubic thermal or volumetric expansion of water (and some osther substances) is a bit tricky because the actual coefficient of expansion of water varies as the water temperature changes.And of course if there is an expansion tank in the system the pressure increase will be controlled so as not to cause leaking at the TPR valve.For another thing, a plumbing system may be restricted against backflow but not absolutely closed.For one thing the water container or tank itself will expand slightly in response to an increase in pressure.In a closed or 'water-solid' water heating system, thermal expansion pressureĮquals approximately 2.5 % of volume for every 100☏ rise. If our water is in a closed or 'water-solid' system, a change in water temperature has a corresponding change in water pressure in the system. The change in water pressure as temperature changes is given on the vertical axis. pressure chart shown here, adapted from Engineeringtoolbox (cited below), water temperature is given on the horizontal axis. If the water system is closed (say by a check valve or a blockage) the result is an increase in water system pressure as well.

Thermal expansion in a hot water system refers to the increase in volume of water as it is heated.

How to Measure or Predict the Increase of Pressure in Water Heater Tanks: Expansion Rate of Hot Water as it is Heated

We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. We also discuss problems that are caused by increased pressures caused by heating and thermal expansion in heating or plumbing systems. We show how to calculate hot water pressure increase in water heaters and boilers as a function of the increase in water temperature. Thermal expansion in hot water systems: This article defines thermal expansion in water equipment in response to temperature, and explains the concomitant increase in system pressure.
