Been messing around with my boiler temp lately, usually keep it lower (around 120°F), but heard some folks swear by higher temps (like 140°F+) for better efficiency. Curious what you all prefer and why?
I've always leaned toward keeping mine lower, around 120°F or so. Higher temps might squeeze out a bit more efficiency, but honestly, I'm cautious about safety and wear-and-tear on the system. Hotter water means more pressure and stress on valves and pipes, and I just don't want to risk leaks or worse... flooding. Plus, from an eco-friendly standpoint, lower temps usually mean less energy consumption overall, even if the efficiency numbers look slightly better at higher temps.
That said, I do wonder if anyone's noticed a significant difference in their heating bills after switching to higher temps. Is it really noticeable enough to justify the extra strain on your boiler? I'd be curious to hear some real-world experiences on that front.
