If you are looking to buy a water heater, decide to choose the most suitable one according to the needs of the house and for that you must take into account several factors, such as: the use that is going to be given, the place of the house where install the water heater and the hardness of the water in the area where the house is located. Below are some of the tips to keep in mind while choosing a water heater and a guide to know which one to choose.

  • Capacity of the thermos tank– The water heaters heat the water that is in your tank through a resistance. When the accumulated water reaches sufficient temperature the resistance is turned off and the water remains inside the tank until there is a demand from the user. Water, unlike gas heaters, does not heat instantly when passing through the appliance. That is why, before making a purchase, you must calculate the capacity that is necessary. When choosing the capacity of the water heater we have to calculate the daily amount of hot water that we will need.
  • Size of the water heater– it is important to note the size of the water heater. You should choose the size according to the space available in your house for its installation.
  • Type resistance depending on the hardness of the water– The hardness of the water in our geographical area will indicate whether we should opt for a submerged armoured electric resistance or sheathed ceramic. The resistance is responsible for heating the water when it is inside the electric boiler, so a resistance of higher quality, may result in the long run, more or less efficient.
  • Budget– before buying a water heater, you should set a budget for your purchase. Shopping without setting a fix budget can create problems for you.
  • Thermal insulation– It is important to place the water heater inside the house to avoid cooling the water contained in the thermos. In addition, it is advisable to install the electric water heater as close as possible to the rooms where we will use the hot water to avoid heat losses. Something that we have to take into account when installing our electric water heater is to leave a distance of at least 50 cm between the electric water heater and the wall in order to perform the maintenance (if necessary) of the electrical elements. We should also consider installing the electric heater on walls that can support the weight of the thermos well.
  • Fixed or adjustable temperature– There are two types of thermos:
  • Fixed temperature thermos. They are cheaper than adjustable ones. This type of apparatus heats the water always at the same temperature, without the possibility of regulating it. Keep in mind that, in the vast majority of cases, it is not necessary to control the temperature.
  • Adjustable temperature thermos. They are more expensive equipment than the previous ones, because they allow indicating, within a range, the temperature at which it is desired to heat the water. This specification is necessary in a few occasions.
