Energy efficiency of the device.
2. THE ENERGY EFFICIENCY OF THE WATER HEATER
According to Delegated regulation (EU) No. 812/2013 of EC, its main criteria is the annual consumption of electricity . No it's fine yes we forget that the main thing purpose on the water heater is yes it heats up the water and respectively to hold her long time warm . This it depends from type and thickness on thermal insulation layer .
Mainly purpose on thermal insulation is yes save energy . Polyurethane foam (PPU) is the most suitable isolation for water heaters . We at " Eldominvest " use always the best systems polyurethane foam . Because the quality on the insulating one material is from essential meaning for energy efficiency on one water heater . It is very important thermal insulation characteristics on the product yes everything keep unchanged through the whole warranty period on the device .
At the water heaters ELDOM we use polyurethane system (PPU) of new generation of Closed-cells , from the group of HFO ( hydrofluoroolefins ). The components are produced from worldwide recognized manufacturer by unique formula , specially for ELDOMINVEST. This one material is with exceptional short potential on globally warming (<2 GWP) and zero influence on ozone layer . It is non-toxic and non - volatile , with excellent energetic efficiency and coefficient on thermal conductivity λ about ~ 0.021 - 0.023 W/ mK ( watt on meter by degree Kelvin ). Owns long term thermal durability and excellent dimensional stability at the sharp ones temperature changes that are a normal phenomenon at the water heaters . These parameters everything owe on the subtle closed cellular structure on the Closed-cells system 97%. That is, 97% of air ones bubbles in the polyurethane foam foam remain closed . Namely them provide the heat isolation .
The parameters on the isolation depend no only from hers quality and structure , but also from some others factors :
- The thickness on the isolation . Through practically trials we are proved that the difference between 30 mm and 20 mm insulation is 7%, and between 40 mm and 20 mm insulation – 13% thermal lost . This one difference it's up unimportant at thicknesses of 60 mm and more , which does the use on so thick insulation unprofitable .
- The even coverage . The right one distribution on polyurethane foam about the water reservoir quite is not unimportant factor . Thank you on the long-standing you are manufacturing experience , we at ELDOMINVEST we are perfected the method for optimally injection molding of the HFO components .
You don't have to yes everything forget that the consumer value on the appliance it depends from his efficiency , not only from the functional ones characteristics . Everyone water heaters warm up the water , but ELDOM is proven to store it warm , not warm up the surrounding space . You can yes discover the differences between the different ones brands water heaters and without such complicated calculations . If yours friends they have water heater , just like you you are liked , at opportunity touch the coat his when the water in it is heated . If feel it nice warming - that it's not accurate yours water heater .
ELECTRONIC SMART CONTROL INCREASES ENERGY EFFICIENCY
The use on electronically management provides opportunity for realization on additional savings on electricity in size on up to 15%. The modern ones models the water heater ELDOM with microprocessor management have an intelligent " self- learning " software with optimization on temperature hysteresis , programming for inclusion priority in low-cost hourly zones etc. Modern ELDOM water heaters with Smart electronic control "self-teach" within a week by monitoring consumption in the household and adjusting their mode of operation so as to provide a sufficient amount of hot water, exactly when it is needed.
