Interruptions with hot water are familiar to everyone. Especially inappropriate in a family with a small child, when you need to wash the baby in time, wash his clothes and hold a wet cleaning at least in his room. Frequent outages of hot water caused by the difficulty of repairing and replacing pipes under cobbled streets can become a nightmare for residents of the historic center of the city. Exit - installation of the water heater.
A lot of questions arise for those who did not encounter such a purchase. How to choose a water heater, reliable, functional, and at the same time not too expensive? Which water heater should I choose to not overpay for the prestige of the company? How to choose a good water heater that does not break down after six months of operation due to water pressure drops or demanding and sensitive equipment?
How to choose the right water heater?
It is worth to listen to the advice of experts and the experience of relatives and friends to determine how to choose the right water heater. Determine which mechanism of water heating is most suitable: electric or gas. From what mechanism you prefer, the criteria for choosing a water heater will depend.
Electric water heater
The main criteria for choosing an electric heater are:
- number of cranes connected to the heater. For one or two valves, an open-type non-pressure water heater is suitable. For a larger number of valves, a non-pressure closed type water heater is required;
- interruptions with the supply of cold water. If periodically the water is disconnected in principle, the ideal option will be a storage water heater. Focusing on the required volume, you can determine how to choose a water heater for an apartment or a house: a large water reserve will be an excellent option for a large country cottage and a bath, a heater with a small tank is suitable for small-scale hruschevok.
- If there is no water interruption , you can choose a flow heater. It immediately heats the water to the right temperature, which is especially important for families with children;
- material opportunities often limit the cost of the proposed purchase. With regard to water heaters, a reduction in the cost of equipment can mean: cheaper materials of internal tanks (for example, glass pharafor, whose service life is 1 year, instead of stainless steel, which can withstand all loads for 10 years), lower power (and therefore longer time for heating), a less well-known manufacturer.
Important! It is absolutely necessary to conduct a separate electric cable to the electric flow-through water heater. Joining a "standard" electrician that has already been carried out is fraught with a fire. In the best case, it will regularly dislodge machine guns.
How to choose gas water heaters?
Also there is a flow and accumulation. Flow is an ordinary gas column. The storage water heater is large in volume and takes a long time to heat the water. When choosing it is important to consider:
- number of cranes connected to the column. If the water heater is used exclusively in the summer kitchen, there will be enough apparatus with a capacity of 16 kW. For the shower is enough 20 kW. In an apartment where water enters one bathroom and the kitchen, it will be enough to have a column with a capacity of 24 kW. More powerful water heaters will require the installation of an additional water supply system, they will cost more, and in the end will not justify the costs;
- serviceability of gas and water supply systems. Modern speakers are equipped with a simulating heating pad, which automatically blocks the operation of the heater in the event of an emergency. Therefore, in older homes it is recommended to install heaters with such a more perfect protection system.
You can save when choosing a gas water heater if:
- Select a heater with an open combustion chamber. The mechanism of this heater assumes natural draft, that is, the intake of air from the room, so these devices are cheaper.
- Acquire a column with a manual ignition mechanism. Even in expensive speakers, the automatic ignition system can break down,
so some advisers advise not to waste money on an expensive system; - Acquire a heater of a lesser known brand. Famous brands guarantee quality, because they fear for their reputation, in turn, little-known manufacturers are trying to conquer the market, so they are striving for no less qualitative production.
What kind of running water heater to choose: gas or electric? With equal installation possibilities, a gas water heater is always preferable: it does not require earthing, additional connection to the network, it does not depend on power outages.
