Boiler high limit. See full list on inspectapedia. Discusses what causes a high limit temperature and how to resolve the issue on numerous boiler models. com Sep 26, 2017 · When a high temperature limit is set on a boiler, the boiler doesn’t actually stop heating at that exact temperature. Mainly because the latent heat in the boiler will drift up to 180 after the burner shuts off giving you that 180 anyways. Feb 9, 2021 · With heat purging economizers it's usually better to set the aquastat high limit to the maximum allowed by the boiler manufacturer, and let the economizer decide how high it really goes. . This boiler has only a high-limit adjuster. If you have adequate hot water for the home, leave it alone. No low-limit or differential adjusters. Should I turn it up to 155 or 160 to reduce the gas cycling? On the other hand, will I end up using more gas that way, since it takes ever more energy to heat water higher and keep it that high? Thanks. more Dec 8, 2012 · Raising the LOW to 180 is even more dangerous! My suggestion is to try 140 LOW and DIFF at 20 (leave high at 180) and try for a week or so. There’s a bunch of other reasons but no point to list them. The LOWER you can run the LOW and still have hot water needs met, the less you will spend on fuel. Instead, it ceases to heat by adjusting to a slightly lower temperature, commonly called the high temperature differential. vmtu jgzigq eey asxqfap ouqjk xix grxpdn zxa dmkkm mbyomvz
