The water heater is essential to supply hot water to homes, to be used for sanitary usefor the housekeepingper cooked, etc. Usually, condominiums are equipped with a centralized system for the production of hot water, but otherwise each house will need to install one for the production of hot water. There are some different types, therefore it may not be easy to choose the right one for your home. In any case, before figuring out which water heater to choose, it is always advisable to find out about the various models (for example, here you will find the best Ariston water heaters) and only then make your choice.
Gas water heater
Lo gas water heater It is one of the most common types of water heaters in homes. There are two types: open chamber or sealed chamber. The first term refers to a system that takes the air for combustion directly from the room that houses the water heater, and emits the fumes outside. On the other hand, sealed chamber boilers not only discharge the fumes outside but also use the outside air in the combustion process. The latter are more expensive than other models, however they also represent the optimal solution for bedrooms small size and if they are to be installed indoors, while open chamber boilers must be installed in a ventilated place. Another subdivision that can be made is based on the type of gas used for combustion. Typically, gas boilers are fueled with the methane or LPG. The performance of both is very similar, however the GPL it must be stored in special tanks, while the methane is connected directly to the distribution network, therefore it could be the most convenient solution. However, some areas of the country do not have a natural gas connection: in that case, choosing a LPG water heater is a obliged.
Electric water heater
The classic electric water heater is equipped with an electric resistance that heats the water and keeps it at temperature for as long as the water heater is on. It is most likely the model most used in our country. Furthermore, unlike the classic boiler, the electric water heater guarantees hot water immediately availablecounting on a reserve of pre-heated water available for use, thus also avoiding the waste of water with an instantaneous boiler.
Heat pump electric water heater
The technology of heat pump has made it possible to apply this method also to the classic electric water heater accumulation. In a nutshell, the heat pump mechanism allows you to draw energy from the air and use it to heat water for domestic purposes, in total autonomy respect to the heating system present in the house. Among other things, it should be noted that if you use renewable energy sources (such as photovoltaic, wind or geothermal energy) to activate the heat pump, these devices allow you to significantly reduce energy waste. According to some estimates, it is possible to save up to 75% of consumption.
