How could mains water pressure affect my combi boiler
Jun 19, 2012 · When the required systems supply water temperature is 180 to 190 F, which is too high for condensing boilers to condense, the system will operate with the less expensive, noncondensing boilers. Based on OAT, the systems supply water temperature shall be adjusted.
Redundant high limit controls and gas valves assure safe shutoff in the event of overheating or flame failure Requires 120V 60Hz, maximum inlet gas pressure of 14 WC and activation of boiler by external temperature control WoRKiNG pReSSURe ASME approved, hydrostatically tested and certified for 160 psi
Feb 08, 2019 · In summary, for optimal operation, condensing boiler systems need the return water temperatures well below the dew point of the boiler exhaust (for natural gas, this is around 140°F in the Bay Area and 125°F in Denver), ideally around 80°F or lower. Non-condensing boiler systems require the return water temperatures to be above the dew point of the boiler exhaust (hence the warm-up loops).
Jun 18, 2008 · The boiler burns the gas to make hot jets that play on a heat exchanger (essentially a copper pipe containing water that bends back and forth several times through the gas jets so it picks up the maximum amount of heat). The heat energy from the gas is transferred to the water.

Jul 16, 2020 · A combi boiler heats water on demand. A system boiler supplies water to a cylinder, which is heated by hot water circulated around it, like a radiator. A heat only boiler is similar to a system boiler, but the water pressure comes from gravity, so the cold-water supply tank is often in the loft. In all three systems,, the water that comes out
