Not sure where the correct place is to post this. I have a new install and have tried to follow all the instructions. The first DHW cycle has just run, but the heat sensor stopped recording a flow partway through it. Emoncms - app view The heat pump has completed the cycle normally, and you can see the temperatures rise as the cylinder comes up to temperature. Similarly, you can see the power being used by the Heat Pump. Do you have any thoughts on how to resolve this going forward? Do I need to reset the sensor? If so, how? Thoughts welcome, or just pointing me to the correct FAQ! System Valliant Arotherm Split 7kw.
Edit: The engineer has installed the heat sensor in this position. Is it at the required 45-degree angle (position A) required in the instructions, or should it be on a slant? Thanks.
Okay, this now looks like this. I’d appreciate it if anyone could tell me if I’ve done something stupid or sensible. This is my interpretation of 45 degrees, but I really cannot see the installation clearly enough and not sure if it will actually solve the problem or not. I will keep people update after tomorrows hot water cycle.
I’m not a heat meter specialist, and please do remember that all we know about you and what you have is what you write here - most people here who can try to help you don’t know what you have or anything about you, however a quick read of the data sheet for your heat meter (and I had to read the make and model off the photo to know what you were talking about) says it can be mounted in any position. So I think if what you’ve done makes it easier to access and read, leave it as it is.
What I do know from reading just about everything written on this forum is air in a heat meter (not specifically yours) can stop it working. There are documents here on how to remove the air, so I suggest there is where to start. The magnifying glass in the header of each page is the search function. The one in the dark blue header also searches the archive - that’s unlikely to be useful for anything heat pump related.
And do have a look through the FAQ - there’s some good advice on what people need to know to best help you.
Thanks, Mark and Robert, grateful for the pointers. @markr, looking at your pictures, my heat sensor was definitely not at 45 degrees. I’m grateful to be reassured, and I now have this corrected. @Robert.Wall, it appears almost certain that some form of air is causing the problem. I’ll see what I can do with the wealth of information you have both opened my eyes to. Thank you!
