Nov 05, 2019 · NON-CONDENSING BOILERS USING PROPANE OR NATURAL GAS. If the thermostats in the buildings connected to a boiler are set so the buildings can use the entire hot water output of a boiler, at say 110F, that's as hot as the water temperature leaving the boiler will get.

Managing Condensate for Condensing Boilers - Automatic Heating
If you've had a new gas boiler installed in the last 15 years, it will most likely be a high-efficiency condensing boiler. In simple terms, a condensing boiler can extract heat from the water vapour in exhaust gasses by passing the gasses through something called a condenser. The condensed water vapour (now just water) then leaves the boiler
In a condensing boiler, heat existing in the flue gasses can be captured and 'recycled' back into the heating system and used to preheat the cold water entering the boiler. During this process, the temperature of the flue gas is rapidly reduced from around 130℃ to 50℃.
Condensing boilers capture the heat given off the boiler's flue and use it for heating the water. Hence, the boiler uses less gas for powering the heating system. All combi boilers are usually condensing boilers. The UK building regulations have made it compulsory for all new gas boilers to use condensing …
Oct 07, 2016 · In a condensing boiler, the water is condensed inside the boiler so more energy can be extracted; in a conventional boiler, the water escapes as vapour and the energy is lost. Lower Operating Temperatures. To be able to condense the water vapour from the flue gas, the condensing boiler should operate using a lower entering water temperature
The condensing process is achieved by passing the piped hot flue gases through the cooler return water flowing back into the boiler. Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less.
