Water heater ideas

Among the various plants that are found in our homes, the water heater is of fundamental importance since it is thanks to it that we get the hot water is essential for our health and for cleaning the house. Let’s see in detail the characteristics of the water heater and the different types exist.The water heater (or heater) is a device that heats the water using, as a source of heat, the combustion of gas or electricity. The electric is typically the most popular model in Italian homes, and its capacity can range from 10 liters up to 80 and beyond, through the standard sizes 15 and 50 liters. There are also two major subcategories of water heater, namely:

Heater in instantaneous heating : in these devices the hot water which is needed is produced on time, according to the request;
Heater accumulation : the hot water is produced in advance of the moment will be actually used, and in the meantime will be kept inside the boiler.
The instantaneous heating water heater are without a doubt the most recommended, since they prevent two major problems that plague models to build. First of all, you do not produce excess hot water when there was no need, wasting energy. But, above all, is not likely to take a cold shower when the water stored in the water heater runs out.

A water heater consists essentially of a reservoir of variable capacity and a water heating system. The tank can have a cylindrical shape or flattened, so that it can be mounted close to a wall optimizing the space available. The heart of the water heater is of course a system that allows the water heater.

Gas water heater
This type of water heater is equipped with a system that burns the gas, said furnace or burner, which is placed inside a combustion chamber. The gas is mixed with air, oxygen-containing, and its combustion generates heat. This heat is then transferred to the water contained in the boiler in several ways:


through the fumes produced by combustion: the fumes are conveyed inside pipes that heat the water that comes into contact; by irradiation, or by transmitting the heat in an indirect way The fumes produced by combustion are then routed to the exterior of the house. These water heaters can operate with two main types of fuels: natural gas and LPG. The water heater fueled by natural gas are connected to the counter at home, so that using them will fall under the bill that concerns the consumption of gas. The LPG models, however, are fed from a reservoir and are ideal for those areas in which it does not reach the network of gas distribution. It is important to emphasize that the water heater to CNG and LPG are deeply different from each other from the constructive point of view, therefore, must be used only and exclusively with the fuel for which they were designed.

Electric water heater
The operation of this type of water heater is secured by a resistance, which heats up due to the electric current that is passed. Also in this case there is a metallic tank, within which is located the resistance (coil) and the water content is heated by the contact with it. To adjust the temperature is also a thermostat, allowing you to get enough hot water for the different needs of the family, such as taking a shower or washing dishes. The water heater is also equipped with a safety valve that allows to drain the water in the presence of a possible excess pressure.

The operating costs of electric water heater are higher than the gas models, since it takes a lot of energy to run them. Furthermore, the heating water is usually slower than that which characterizes the water heater combustion, but on the other hand it is good to remember that electric models have the advantage of cost less. In light of these pros and cons, the choice of one or other type of water heater must be evaluated very carefully.

Condensing water heater
There is also a particular category of water heaters that significantly reduces the operating costs. It is a condensation of the water heater, which work with a very high efficiency and therefore provide energy efficiency and savings, together with the reduction of polluting emissions. But how do they work exactly?

Similarly to what happens with condensing boilers, water heaters in these thermal energy produced is not wasted, but the fumes produced by combustion are reused to take advantage of the residual heat. The exhaust gases are cooled in the substance to reach the condensation point (or dewpoint), a change of state from gas to liquid that emits heat. The temperature of exhaust smoke from these condensing water heater is so much lower than conventional gas water heater.

Maintenance
In order for your water heater can enjoy a long life and keep always in perfect working order, it is essential to submit periodic maintenance. Some of these maintenance operations can be carried out on their own, while for others it is essential to the intervention of a professional who can solve any serious problems on the device. For example, you need to call a technician to a control when the water heater is not working as it should, or unusual noise or vibration. The maintenance by specialists may also comprise, for example, the replacement of mechanical components or gaskets. Other important maintenance operations can be carried out safely on their own, arming itself with a little ‘patience.

Much of the Italian territory is characterized by the presence of hard water, ie containing large amounts of salts (limestone) dissolved. These salts, with the passage of time, tend to accumulate inside the water heater, exactly as it happens with the resistance of our washing machine.

Scale deposits should be removed periodically, and to do that you have to turn the water off and disconnect from power. After you empty the water from the tank by removing the cover and pulling out the resistance. To clean you can use a sponge and a descaling agent, but if the deposits were too there is choice: you have to replace it.
