Bosch Combi 151 Very low hot water flow at all faucets
I recently purchased a home with a wall mounted Bosch 151 that was installed in Dec. 2016. My system is on a well. The cold water comes out of the faucet with great pressure but when you switch to using the hot water the flow drastically decreases. i would say by more than half.
Any thoughts on what could be causing my issues?
