Gone are the days when you had to give up the blessings of civilization to travel to your dacha. Now you can equip a country house with the latest technology – including ensuring the constant availability of hot water. How to choose a flowing or storage water heater for a summer residence, read below.
boiler requirements
A summer cottage water heater is always useful: bathing, washing hands after gardening, washing dishes, doing laundry – these processes become easier with hot water. Especially if you have children.
Which water heater is better to buy in the country? To find the answer, decide on the requirements for technology. What tasks should she perform?
- Principle of operation. What type of energy does the device work on? It can be electricity, gas, solid fuel. In the latter case, you can arrange heating in the room. How to make an indirect heating boiler, read in a separate article.
- Water volume. How many people will use water, in what volumes? By calculating this, you can rationally choose the technique.
- Difficulty in installation and operation. Is there enough space in the room to accommodate a large tank? If not, it is better to choose a flow device. Think about whether it will be possible to install the boiler yourself.
How to choose a water heater
Consider all types of boilers to make the right choice.
type of instalation
Depending on the design of the walls and the area of uXNUMXbuXNUMXbthe room, you can give preference to:
- wall. Rational placement – the tank does not take up useful space in the room. However, the capacity will not be too large, especially if the wall structure cannot withstand the load.
- Outdoor. The device will provide you with large supplies of water. The volume starts from 200 liters. To accommodate the unit, you will need a large room or a separate room.
Principle of operation
Electric water heaters are divided into several types depending on the operating conditions. For houses and apartments are most often used:
- Bulk.
- Flowing.
Indirect heating devices are also suitable for giving. Their device is quite simple: the upper part of the tank is used for water, a firebox is organized in the lower part.
The disadvantages of the technique are:
- High fire hazard.
- Large dimensions.
- The need to constantly add fuel.
Solar collectors are a great way out in the summer season. They do not consume electricity at all, they use sunlight as a source. How to make a solar water heater, read in the previous publication.
Let us dwell in more detail on the choice between a storage and flow boiler, as these are the most common models. Installation can be carried out independently, and the choice in stores is huge.
Storage water boiler
The electrical device consists of a tank and a heating element. Water accumulates in the tank, reaches a certain temperature, which is constantly maintained. Provides multiple intake points so you can get pressure on both your shower and faucet at the same time.
What to consider when choosing:
- Performance. If you rarely visit the country, a volume of 10 liters will suffice. If you often spend time there – 50 liters. For family and frequent use – from 90 liters. Consider the heating rate (30 minutes per 10 liters) as well as the energy consumption.
Important! In the absence in the winter season, the water from the heater must be drained, with a rare visit, it must be warmed up. Read how to drain water from a water heater yourself.
- Choosing power products, make sure that the wiring in the house is normal. Old wiring and sockets may not withstand a powerful device.
- Pressure or non-pressure models? If there is no permanent water supply, then buy a non-pressure one. Its operation does not depend on the pressure in the line, which means that the heating and water pressure will be constant. Minus – the device can provide only one point: a faucet or a shower.
- Hull shape. The cylindrical body takes up a lot of space. To save space, choose a flat vertical or horizontal tank. If desired, the equipment can be hidden in a niche, closet.
- Heating element type. Consider the quality of water in the region. If it is very hard, give preference to a dry heating element. The spiral is placed in a protective flask and is not exposed to scale.
- Housing material. The most reliable is a stainless steel tank. But if you do not plan to use the boiler often, you can take an enameled tank. Manufacturers promise trouble-free operation for 7 years.
The choice of the manufacturer is yours. The most popular brands are “Termex”, “Ariston”, “Electrolux”. Although most models are made in China.
Flowing water heater
The device also consists of a body and a heating element. But water does not accumulate in it, but passes through the heater. What are the pros and cons of protochnik?
Advantages:
- Fast heating. Within 30 seconds, the passing stream heats up. You get hot water just by opening the faucet. This is convenient for intermittent use: no need to drain water, worry about stagnation or corrosion.
- Compact body. The boiler for several points has small dimensions, it can be placed in the kitchen or in the bathroom. Equipment for one point of the fence is mounted directly on the crane, in the nightstand, niche. Instantaneous shower water heaters already come with nozzles.
- The amount of water is not limited by the volume of the tank. It all depends on how you calculate the performance of the device. Read the article: “How to choose the volume of the water heater ».
- The cost is much lower than storage technology.
Of shortcomings can be distinguished:
- Great power. Since the heaters consume from 5 kW, immediately take care of organizing the wiring and sockets with grounding. Although the protochnik does not consume electricity during non-working hours, it draws a lot during heating.
- The quality of the pressure depends on the pressure in the pipeline.
- There will be no hot water when the electricity is off.
By type of installation, you can choose:
- Stationary device. It has the highest power, so it can provide several fence points. The principle of operation allows you to fill the bath without problems.
- Faucet heater. This is a holistic design that is suitable for washing hands and dishes. By opening the mixer, you will get a hot stream.
- Attachment on the crane. The principle of operation is similar to the previous one, but the power is much less.
It is worth considering how to provide the heater with a flow of water. If the water supply is not laid, then you will have to install a circulation pump, and also compare its power with the performance of the boiler.
Installation Recommendations
To successfully complete the installation, follow these recommendations:
- Prepare wiring, organize grounding. Install a cleaning filter if necessary.
- Check if the wall can withstand the weight of the water storage tank. Install reliable fasteners, they are included.
- It is better to have equipment closer to the fence point. So you reduce heat loss.
- Connection of cold and hot water is carried out exactly according to the instructions.
- Make sure that the water is connected, only then start work.
- Adjust the values on the control panel.
Approach the choice of a boiler rationally, weigh all the pros and cons. After all, technology should bring maximum benefit, not problems and high costs.
