Condensing boiler is a type of boiler in which condensing technology is used. With the special heat exchanger structure that condenses the steam in condensation technology, efficiency up to 109% is achieved by making use of this latent heat of evaporation. Thus, a high rate of fuel savings is achieved. Condensing boiler models created using new generation technologies provide benefits in terms of heat generation and recovery as a result of reusing waste heat by condensation technique. As it is known, old generation gas or liquid fuel boilers release the heat contained in the waste gases to the environment without using them. However, with the principle of heat recovery in condensing boilers, this heat is reused with the condensation technique without being released to the environment. You can achieve an efficient heating performance thanks to the condensation technology, which both increases the performance of the boiler and provides significant energy savings. The burner system is generally premixed. Wall-mounted and floor-mounted models are available. Multiple boilers are connected side by side in cascade and the capacity can be increased.
