When there is a hot and cold water option, many will go for the former. It is among the comforts many people will want to have. However, it does not just happen. It will need to be heated before it finally reaches your tap. There are many kinds of water heaters and the experience you will get will depend on that. You should not just be all about the water heater but also if it will offer the perfect temperature and the cost is affordable. It is crucial for you to have all the facts about buying a water heater if it is the first time you are doing so because it makes the process much simpler for you. When you have outlined your exact objectives it will be very easy for you to decide on the path you will take. Put into consideration the number of people living in the particular household and what their daily habits are like. 40 t0 50 liters of hot water should be enough for the average household. If you do estimations without giving it much thought, you might end up having to use cold water when the water heater fails to do the job properly. Also, you do not want to overestimate the hot water need because the electricity bill will go up as well.
You will be lucky if you find the water heaters which can memorize your daily consumptions so that the hot water production can be adjusted based on the needs. In addition, you have to think about the water quality. If the water is soft or balanced you have nothing to worry about. There will be scaling on the water heater if you are exposing it to hard water. In cases of aggressive water, there will be tank corrosion which can take place at a very high rate. Therefore, go for water heaters which have a Steatite heating element. Also, ensure they have an enameled steel sleeve protection. Water softeners, if not well tuned, will increase the water aggression and this is one of the reasons why your water heater tank might corrode much faster.
No one should tell you the kind of water heater model to choose because your needs and preferences will guide you to pick what you are comfortable with. There are solar water heaters and the conventional electric one. Do not forget that the point you install the water heater at will have an effect on how well it will function.
