What Is A Boiler Heat Exchanger? First up. What is a heat exchanger? A heat exchanger in your boiler works by converting the energy (heat in this case) from gas, over to your water. Water passes through the heat exchanger in the boiler, heating up in the process. The water is â€¦
Gas condensing boiler with 10 years guarantee on the heat exchanger ROTEX GW top With a power range of 12-33 kW, the wall hung gas boiler with condensing technology can be used variably. ROTEX also provides a 10-year guarantee on the heat exchanger. The GW top gas boiler offers maximum efficiency for heating and hot water.
2019-11-1 · INOX-RADIAL HEAT EXCHANGER. As is the case with all Viessmann gas condensing boilers, the Vitodens 111-W is equipped with stainless steel Inox-Radial heat exchangers. This technology brings with it an extremely high efficiency rate of 98 percent and exceptionally reliable and efficient operation during its long service life.
2019-11-8 · A condensing boiler has a larger heat exchanger, so it recovers more heat, sends cooler gases up the flue and is more efficient. Sometimes the flue gases get so cool that the water vapour in the gas condenses out, hence the name, and even more energy is recovered from the condensing vapour. Things to consider
from China Suppliers, you can buy quality Gas Boiler(Condensing) from Guangdong ROC Cool And Heat Equipment Co., Ltd..
2019-10-15 · Condensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved, compared to 70%-80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.

Condensing Gas Boilers. Condensing gas boilers function at extremely high efficiency levels because of their design. Condensing boilers are designed to preheat water from the mains cold water tap before it is heated by the boiler's burner. The water is already warm so takes much less time to heat, saving on both energy and heating costs.
Highlights Design factors for a heat exchanger and a boiler were investigated using a simplified model and pilot boiler. The heating efficiency of the boiler developed was about 90% at the optimal designed heat exchangers. NOx and CO emissions were about 30 ppm and 160 ppm, based on a 0% O 2 basis and at an equivalence ratio of 0.70.
