How to improve the energy efficiency of boiler systems

Jan 08, 2016 · Outdoor air temperature reset and warm weather shutdown controls when applied correctly can result in significant energy savings making condensing boiler a viable solution. Neither the reset control nor the warm weather shutdown is applicable in the domestic hot water operation making the condensing boiler less effective.

What water temperature should my boiler be set at?

The average setting for a gas-powered hot water boiler is 180°F. This provides the appropriate level needed for most cold weather temperatures.If you can raise the temperature manually, do not set it any higher than 210°F (which is often the limit), and try to remain down at 190°F if you need the extra heat.. Hereof, what temperature should my hot water boiler be set at?

Protecting Boilers Against Flue Gas Condensation | 2017-08

Aug 14, 2017 · Notice the water temperature entering the boiler is now 130°. Given the same 20-gpm flow rate through the boiler, the temperature rise across the boiler will only be 5.1°, and its outlet temperature will be 135.4°. This higher water temperature now enters the hot port of the mixing valve. DON'T ASSUME

How hot is steam from a boiler?

The main difference between a steam boiler and a hot water boiler is the amount of energy each uses. A steam boiler must burn more fuel (gas or oil) to raise the temperature of its water to boiling level, and this makes hot water boilers more energy efficient, using approximately 25% less energy than steam boilers.

Flue gas temperature or flue gas loss | Bosch steam boiler

The flue gas temperatures at the boiler outlet are normally roughly 60K above the temperature of the product inside the steam boiler. At an operating pressure of 10 bar, which corresponds to a saturated steam temperature of 185°C, the flue gas temperature is therefore roughly 245°C. This corresponds to a flue gas loss of roughly 11%.
