Condensing boilers | Jeremias UK - chimney systems

The high efficiency of the condensing boilers results from the fact that heat produced in the condensation process is used to increase heat supply. The exhaust gases are cooled well below 120°C hence the maximum condensate happens in the flue system chimney.

Watertube vs. FireTube Comparison | Gasmaster

Condensing boilers reclaim that latent heat by condensing the water vapor and transferring its heat back into the return water, which increases boiler efficiency from 80% for conventional boilers (which may be considered exceptional for a conventional non-condensing boiler!) to on average 95% (see Fig. 1).

Plant Engineering | Gaining efficiency from hydronic

2018-5-22 · Due to better heat exchange technology, a condensing boiler typically will operate at a thermal efficiency several points higher than a noncondensing boiler, even at noncondensing conditions, according to Bottorff. However, the best return on investment will be at lower return-water temperature conditions.

Changing atmospheric boilers to condensing boilers

Hydraulics. Modern boilers with low water content are less tolerant to fluctuating flow conditions in the heating circuit so a low loss header is recommended to safeguard the condensing boilers from low flow conditions. The provision of a low loss header ensures that a steady flow of water is maintained through the boilers protecting them from potential damage as a result of firing when there

2019-10-26 · Condensing boilers achieve their rather remarkable efficiencies by operating at low temperatures (return water temperatures at less than 120 degrees F or so, depending upon manufacturer and model). The low return water temperature works to remove a lot more heat from the hot combustion gasses, dropping them to temperatures below their dew point.

Keeping condensing boilers running in winter | AA

Condensing or 'condensate' boilers work in a similar way to conventional gas boilers, but use energy more efficiently by reusing heat from the flue gases to heat additional water. During this process the boiler produces left-over water vapour that cools to leave 'condensate'. This condensate is disposed of through your home's waste water system.

Radiant – – boilers and water heaters

It is true that most homes in North America are heated using forced air furnaces. In Europe, and other parts of the world, where energy is much more expensive, virtually all space heating and domestic hot water heating is done with boilers. Simply put, water is a much more efficient way of heating; greater efficiency means lower energy costs.
