ELDOM green energy solutions

COMBINED WATER HEATERS WITH ONE OR TWO HEAT EXCHANGERS

The rich portfolio of combined ELDOM Green Line water heaters allows our users to choose the most suitable model that meets their needs:

• with volume from 80 to 2000 liters,
• for horizontal or vertical wall mounting, for floor mounting,
• with one or two the heat exchanger,
• with conclusions on the left or to the right of pipes and electrical supply,
• with electronic or mechanically management,
• with enameled or stainless steel water tank.

Mainly advantage on the combined water heaters is that in the process on exploitation on alternative energy sources almost or at all no is imposes the use on electricity. Models with one or two the heat exchangers are an integral part of installations using​ alternative energy sources: heat pump, solar and collector and through summer, local heating installation through winter. The water is warms up through efficient heat exchangers, through which circulates heat transfer fluid. The backup electric heater is includes only, when the alternative energy source is not enough for receiving on the desired temperature on the water.

• Upper the located serpentines is connect to high-power sources on energy, such as boilers and fireplaces. In this case no is accumulate warmth throughout​ volume on water heaters, but the device works in progress mode and provides on practice unlimited quantity warm water.
• Low the located serpentine we recommend yes is connects to low-power sources on heat like thermal solar collectors. So is warms up as much as can bigger quantity warm water, using the accumulator effect and good insulation on the water heater. This option requires space for placement on the solar ones collectors and competent installation on the pipes routes for heat transfer fluid.
• also offer water heaters with two parallel located the heat exchanger for combined use on two the heat source. The coils are located throughout​ volume on the device in order to maximized efficiency at warm-up on the water, regardless from the season.
• Heat pump systems are an increasingly common solution for heating and cooling spaces in the home and office. Especially for them, we have developed highly efficient water heater models with one or two collector coils with a large heat exchange area.
• Our combined stainless ELDOM Green Line water heaters are equipped with innovative corrugated serpentines from stainless steel AISI 316L. They are 15% larger heat exchange area,  faster and more direct heat exchange compared to traditional tubular serpentines.

HEAT PUMP WATER HEATER

This is perhaps the simplest and at the same time the most modern solution to drastically reduce your hot water bills. Air-to-water heat pumps can be monoblock and split systems. Our ELDOM Green Line T-water heaters are of the split type, consisting of 2 modules - an outdoor air conditioner and a water heater with a built-in condenser. The two units are connected by copper pipes through which a refrigerant flows. The Green Line T-water heaters have all the capabilities of the ELDOM electric water heaters, but with some significant advantages:

• over three times smaller expense on electricity from the conventional ones electric water heaters;

• easy is install on the place on the old one electric​ water heater because of the identical them dimensions;
• have high energy efficiency, because are equipped with special thermoregulatory valve and innovative capacitor – aluminum heat exchanger, installed around the water tank, with a large contact area;
• The device has a built-in intelligently electronically control , made in Bulgaria especially for heat pumps ELDOM water heaters;
• also offer models with built-in additional solar heat exchanger, for use on the free one solar energy.

HYBRID WATER HEATER

ELDOM Hybrid is our latest, ecologically clean and economical solution for warm-up on the water which uses 100% free energy from the sun, transformed directly from photovoltaic panels (without the need from inverter). This product is unique on Bulgarian market:

• works as with right current from photovoltaics, as well as with variable current from the electric network;
• the integrated MPR tracker and the electronic intelligent control​ algorithm, developed in Germany, provides maximum production on photovoltaic panels in any temporal conditions;
• ELDOM Hybrid is the cheapest accumulator on free solar energy. The water heater uses electricity from the network only for additionally warming up on the water through the second heater;
• the installation of ELDOM Hybrid is extremely easy, thanks on a Plug and Play system. Mounts is as standard electric water heater, and photovoltaic modules is connect easily with the help of of MC4 connectors. For the effective work on the hybrid water heater, is enough yes be powered by two to four standard 400W photovoltaic panels with 60/120 cells.
