@jerzone I believe the charge in the expansion vessel would be set before filling and commissioning the system, and depend on static head amongst other factors. Perhaps before tinkering it’s worth just doing two pressure checks a week apart under similar conditions - preferably early morning before the system heats up 🤷‍♂️ I’m sure there’s a proper expert on here somewhere #SolarThermal

Using #hydrogen for heating may sound attractive at first glance. However, all of the independent research on this topic comes to the same conclusion: heating with hydrogen is a lot less efficient and more expensive than alternatives such as #heatPumps, #districtHeating and #solarThermal such as #PVT.
