We recommend condensing boilers. Adapt to the new regulations that come into force in September 2015. Condensation technology significantly increases the efficiency of the boiler, whose performance reaches up to 109%. The water vapor contained in the combustion gases contains energy and this energy is recovered and transformed into additional energy. Condensation reduces polluting emissions to negligible levels. It is an excellent investment when choosing a new heating and domestic water system. Furthermore, condensing boilers are the ideal support system to combine with solar thermal systems, since they save more than half the energy compared to conventional boilers. Depending on the system, you can save up to 30% on your gas bill. In summary, why install condensing boilers? - Environmental care. - Savings on your bills.
