Hot water in necessary quantity is one of the main requirements in the modern world. In case there is interruption in the system of the central water supply or in your room supply of hot water is not provided, water heaters come to the rescue.
Designation "accumulative" speaks for itself. Such device has certain capacity which is filled with the cold water heated to the necessary temperature. The gas heater allows to receive hot water much cheaper, than in electric analogs. So, if to organize autonomous providing country residential building, the variant on gas is optimal.
Main advantages of the gas store
The first that should be noted is power. So, electric models, as a rule, have capacity no more than 3 kW, and the gas boiler – 4-6 kW. It means that heating of water up to the necessary temperature will require much less time. Secondly, it is known that gas costs much cheaper, than the electric power. And though the gas water heater will be to you more expensive, later you will be able significantly to save.
Equipment shortcomings
The main problems are connected with mounting of the water heater. The boiler needs the centralized supply of gas and cold water. Therefore, as a rule, it is installed in kitchen or in point, most to it approximate. Because the central part of the gas boiler is the combustion chamber, installation is directly connected with to what type it belongs. So, at the open camera all process of burning happens under the influence of natural draft, and it will demand arrangement of flue and obligatory continuous air flow. Here the moment of calculation of drawn-off point plays very important role, all exhaust air needs to be taken away, and fresh regularly to give. Malfunctions of system of circulation of air exchange can lead to supply of carbon monoxide to the room that threatens with poisoning. Those devices that use the closed combustion chamber type, carry out air supply in the compulsory mode. The small flue is established, and all exhaust gas leaves out of borders of the room through special opening in wall. The difference in models is obvious, they differ also in cost, the water heater with compulsory giving costs much more expensive. Modern gas water heaters are equipped with the reliable system of protection. At maloperation of the device the gas supply immediately stops. The control unit which, in addition, watches the set water temperature and trouble-free operation is responsible for this work.
Choice of the gas water heater: what it is worth paying attention to
1. Tank volume. It is rather easy to define it: the volume of water has to satisfy needs of all family and at the same time not spend resources for nothing. Count, proceeding from approximate norm in 50-80 liters on the person. At the same time it is important to define the place for mounting at once, it is not so simple to find room for tank of the big size. 2. Pay attention to what internal part of tank is made of. Admits to the most durable titanic and corrosion-proof coverings, however they are the most expensive. 3. Get model with extent of heating necessary for you.
