We been lowering our boiler water temperature to 45 degrees (from 60), and notice no difference beside it taken maybe 10-15 second longer to get hot water.

Is there’s any risk for running boiler at that low a temperature?

Yeah, if you have a storage tank you have to keep it hotter to prevent legionnaire’s disease. The bug doesn’t survive above 60, I would set the outflow a degree or two higher to be sure. But if you have a combi boiler with on-demand hot water you can do 50. But IAMAP etc.
