Boiler Defro Delta Plus 22 kW
DELTA PLUS boilers distinguished by modern design characteristic of automatic boilers. The use of precisely blended, multi-system air supply to the furnace combustion ensures good performance for a wide range of fuels with different grain size. The boiler has an innovative vertical plate heat exchanger, ensures optimum exhaust flow and provides the same high efficiency boiler. S3P driver used with the modified PID algorithm provides even better performance, through lower fuel consumption compared to standard controllers. The control system works with two pumps, and hot water, but it can be successfully extended with eg. mixing valve module or room control.
- wood pellets,
- 4 years for tightness of the boiler's exchanger.
- 2 years for other elements.
