    Hello, I have a question: I have a new Biwar viking 55l boiler. I am wearing a pressure reducer with a manometer and set to 2 bars and it is still ok here, but when it starts to heat up to 50 degrees, the pressure rises to 8 bar and it starts dripping intensely from the safety valve. Is this normal?

    This is normal as the water pressure increases during heating. If the safety valve does not open, the boiler may be damaged.

    Expansion vessel on the power supply you have?

    Unfortunately, there are no dishes.

    Exactly - to avoid dripping, you can install a small diaphragm vessel, which will alleviate the pressure increase in the boiler caused by heating the water.

    This is what causes the safety valve to trip.

    And this pressure is normal or so because I'm afraid if it warms the water up to 70 degrees or something will happen?

    Not . This pressure is way too high.

    It will drip from the safety valve until the pressure drops to such a level that the valve closes.

    but we don't know what the valve opens at.

    The safety valve is the last resort. The dish must be there !!!

    I have no technical possibilities because such a vessel should be mounted, is it really necessary?

    I noticed that it is enough to turn on the hot water tap for a second and it drops to the set 2 bar.

    It doesn't have to be, it is recommended. I think that the vast majority of apartment block dwellers with water heating with a boiler, especially small bathrooms, have nowhere to install, one more device.

    And this is normal, because it plays a similar role as a safety valve.

    Well, that's the point, I can barely put the water collecting vessel there, so is it ok or do I have to use something else besides the vessel?

    Must, because they will not take into account the warranty on the boiler in the event of a breakdown.

    If you do not have space, just drain the water through a hose to the sewage system or, for example, to a washbasin. You can lower the heating temperature and then the pressure will not increase as much.

    If there is such an entry in the boiler warranty, because when buying a boiler, there is a safety valve that must be installed.

    It's not just about dripping, but how do I set a higher temperature of 70 degrees per hour to kill the legionnaires, or will nothing happen?

    Nothing will happen because the safety valve will work. But as I wrote earlier, this is a last resort. If you want to sleep in peace, only the expansion vessel saves you.

    It will pop and it will stop.

    I have no place for the vessels, to mount it, if something needs to be done, please give me a different suggestion. In the warranty, I only write about the safety valve.

    I do not force anything on anyone. I propose, explain the action, and the decision is up to the "client". If there is something that cannot be installed, then I disagree, and the vessel is voluntary.

    Is the regulator only for the boiler or for the entire installation?

    On the boiler.

    You can lower the pressure of the water supplied to the boiler, so that the consumption of hot water will not be problematic. This will reduce the pressure build-up due to heating somewhat.

    I think I have to leave it as it is, because if it decreased to 1.5, it is too weak. For now, thank you for the answers, I have to hang up, but please write if something comes to my mind, I will read it tomorrow. Regards.

    There are safety valves connected to a non-return valve. If it is enough to withdraw the water into the pipes, if the pressure is too high, it is dripping outside.

    The non-return valve is used to shut off the return of water to the system and whether it is integrated or not, its task is only that. From other circumstances (installations) it is known that it works with a slight delay - hydrophore pumps, but this is natural => the pump pumps water to a certain pressure, turns off, and looking at the pressure gauge, we can see that the pressure has dropped, because it takes a few moments for the valve to open will close !!!

    What I wrote about is not an ordinary check valve. At a pressure below the setting, it works classically, after exceeding how it can pull the water "back", when the pressure does not drop further, it releases it outside.

    The situation is absolutely unacceptable with this backflow of water. An anti-contamination valve should be installed in the installation, which prevents the backflow of water as this would contaminate the entire water supply system. If the receiving installation has a small capacity, the right solution is to install an expansion vessel in it, and that's it.

    Thanks for your support. However, I was right.

    I am asking for a specific model, because I was looking for a bit on the Internet and I did not find one. I completely agree with

Topic summary

The discussion revolves around the Biwar Viking 55L boiler, where the user reports that the water pressure rises to 8 bar when heated to 50°C, causing the safety valve to drip. Responses indicate that pressure increases during heating is normal, but 8 bar is excessively high, potentially leading to damage. Suggestions include installing an expansion vessel to mitigate pressure spikes, as the safety valve is a last resort. The user expresses concerns about space for additional equipment and the implications for warranty coverage. Various solutions are proposed, including lowering the water supply pressure and using a hose to drain excess water. The importance of a safety valve and anti-contamination measures is emphasized to prevent backflow and contamination of the water supply.
