HOW TO CHOOSE A WATER HEATER?

Whether taking a shower, washing dishes or preparing food, having a good water heater is essential to have water at a good temperature in a short time. Undoubtedly, it is a domestic appliance that gives us great comfort when carrying out our daily tasks, so choosing the right one is important to obtain the performance we need. Here we will tell you how to choose a boiler taking into account the options that are in the market and the aspects that you must evaluate in your home.

How to choose a water heater?

Housing type

Although currently most boilers can be used both at home and in apartments, the needs of each home are different. In an apartment, the water heater is usually installed indoors, while in a house it is common to find it on the patio or even on the roof. Therefore, it is important to choose a boiler that adapts to the size of the space where we are going to place it and at the same time provides practicality and safety.

Type of energy

Currently, we find water heaters that work with natural gas, LP gas or electricity. However, to choose the one that suits us best, we must first ask ourselves questions such as how many people are going to use it? How much hot water do we consume? Do we have the corresponding installation for one or the other? Once this has been evaluated, it is time to review the advantages and disadvantages of each.

Natural gas 

  • Service availability 365 days a year.
  • It is distributed through steel or polyethylene ducts installed in the ground.
  • The construction of the infrastructure is carried out by distributors authorized by the Energy Regulatory Commission (CRE).
  • The distributors monitor the network and offer 24-hour attention to leaks.
  • It is lighter, so it disperses quickly in the air in case of leaks.

LP gas 

  • It is distributed through pipes to supply the stationary tanks of the homes.
  • Tanks must be maintained regularly to control leaks.
  • The tank must be properly installed and well ventilated.
    • It is heavier, so it usually goes directly underground in case of leaks, increasing the risk of explosions or poisoning.

    Electricity

    • It is safe by not using fossil fuels.
    • It does not require periodic reviews or monitoring to guarantee its operation.
    • It does not need a minimum flow for the water to circulate through the heater.
    • It is easier to install, since it does not require a gas infrastructure.

    Heater type

    Although water heaters can be classified according to the type of energy (gas or electricity), they are also identified by their system or operation . The most common models are the following:

    Deposit

    It is characterized by including a container to store water. It is necessary to leave it in pilot mode so that, as soon as it cools in water, the burner ignites automatically. The time it takes to heat each liter per minute will depend on the model or brand. For example, for those of 200 L the waiting time can vary between 35 or 50 minutes. To select the necessary capacity, we must take into account the number of services and people at home alike.

    Advantages and disadvantages:

    • It can be installed away from the shower, since they do not need water pressure.
    • Due to its operation, consumption is high, but if it is turned off when it is not in use, it can be very economical.
    • We must wait for the tank to reheat each time someone finishes bathing.
    • It is one of the systems that warms the most, being ideal in cold season.

    Fast recovery

    It also uses a storage tank and requires the pilot to remain lit. However, the tank is smaller, so its capacity usually varies between 6 and 12 liters. As for the burners, these are larger, facilitating the heating of water in less time.

    Advantages and disadvantages:

    • Provides hot water continuously.
    • It can be installed in confined spaces.
    • They include a sensor that activates and deactivates water heating, generating greater resource savings.
    • Depending on the frequency of use, the water may sometimes come out warm instead of hot.

    A recommendation of this type of boiler is the Bosch 6-liter pass- through water heater or the Bosch 12-liter LP gas or natural gas rapid recovery water heater , both of which have high-powered burners and electronic operation to provide greater practicality and safety. .

    Instant pass

    You don’t need a water container or a pilot. Instead it incorporates a conduit through which the water passes and heats up instantly. The heater is turned on automatically by means of a valve, which is

    activated and deactivated by opening and closing the tap. Due to their design, they take up little space and consume fewer resources, since they only heat the water when the tap is turned on.

    Advantages and disadvantages:

    • They cannot be installed outdoors.
    • They require maintenance more frequently.
    • We have hot water with no waiting time.
    • They require sufficient energy power, if large quantities of water are to be heated.
    • They need good water pressure.
    • Quick on.

    Number of services

    Another factor to consider if we do not know how to choose a boiler is the number of services in the home. This will determine what capacity the heater must have to meet our needs. For example, a service is equivalent to a shower, an average washing machine or two sinks, which generally consume 6 liters of water per minute, so from this approximate we can evaluate how many liters we require.

    A recommendation for single-service dwellings is the Bosch 7-liter pass-through heater , especially if only one person lives at home; while a good alternative is the water heater tank 40 liters Bosch, both natural gas and LP gas,  if the service is 1 to 3 but living people at home.

    Now if in our home we have 2 services, which is equivalent to 2 watering cans, water heater tank 80 liters Bosch is a viable option either version of natural gas and LPG . In addition, it has an electronic thermostat without a pilot, which allows the boiler to turn off and on automatically when the water cools.

    Water pressure type

    Some heaters require good pressure to operate, such as instant boilers. Therefore, before choosing a heater we must check what type of pressure we have at home. One way to do this is by turning on a tap to the maximum; If the water splashes it has good pressure, otherwise it is low. We can also verify this by placing a 6-liter bucket of water under the tap and leaving it open for 1 minute; if it fills up then there is good pressure.

    In case of low pressure, the Econo Bosch 6-liter instant heater is recommended . It works well with these types of limitations and, in addition, it has a triple safety system to prevent toxic gases, gas leakage and temperature limiter. On the contrary, if we have high pressure, the 13-liter Bosch Comfort heater is recommended , perfect for working with normal pressure.

    Tips for a good boiler performance

    Although, all the previous points are important to know how to choose a boiler, there are some external factors that can influence the performance of our equipment:

    • The energy consumption can increase or decrease, depending on where we place the boiler. For example, if you are in an area without heating or where the cold is enclosed, you will consume more resources to heat the water.
    • If it is not necessary to use very hot water, try to modulate the temperature. This will also save energy.
    • If the boiler has a pilot or automatic ignition, it is best to turn it off if we are not using it. This way we will also reduce spending.

    No longer suffer from running out of hot water when you need it most. Now that you know how to choose a water heater, evaluate your options and choose the ones that best suit your needs.
