I have tankless hot water which has been working well up until this week. A week ago we discovered a leak on the hose from the propane tank, so we replaced the hose, but since then it hasn't seemed to want to heat the water much.
Most days it warms the water to around 25-30 degrees Celcius, and takes a few tries of turning the water on/off over a few minutes before it finally decides to actually get going and heats the water properly.
But this morning we haven't been able to get it going - it warms to around 26C, which is noticeably warmer than the cold water (so it's definitely doing something), but not too comfortable for a shower!
Now I'm not a DIY/Home-Improvement guy, but we live in a place where it's difficult to get someone in to take a look, so I'm wondering if this is something that's common or easy to fix, or a known problem?
The gas tank is full and fully open, and I've adjusted the dial on the system to extremes (photo shows where we usually have it set).
