Determine the minimum winter outdoor temperature in your area, look at the outdoor temperature column: -5ºC; -3ºC; 0ºC and + 5ºC.

Once in the column you have selected, find the square meters of your home.

Once located in the square meters of your home, scroll to the left and you will see the power you need and the heat production equipment, there are two columns, one for heating equipment and the other for heating equipment and sanitary hot water for bathrooms and kitchen.

Do not be surprised if the power shown in the table does not match the power of your combustion boiler or your old electric boiler, it is normal for our equipment to have a much lower power.

As you can see, the powers of 4.5kw and 7.5kw can be supplied to connect to 230V II or 400VIII, depending on the electrical installation you have, the rest of the powers connect to 400VIII, which is a normal voltage in large homes.

Exchanging the old boiler for high-tech ete brand because it is common when calculating electric boilers of other brands to install 30 kW electric boilers to heat the same surface.

Ete electric boilers can replace any type of electric or combustion boiler, the replacement can be done by any plumber with the support of the electrician who installs the power supply cable.

When you consult the ete technicians, they will provide you in writing with all the information you need to make a safe boiler change decision with a 10-year warranty.
