Boiler on 15 liters for the kitchen, office or cottage

Boiler on 15 liters – this is a compact storage water heater, which allows you to organize local hot water supply there, where there is no need for a large supply of water. This volume is most often considered for the kitchen, small office, workshops, dacha or a separate bathroom. A small body takes up a minimum of space, and heated water is enough for short household operations without installing a full-sized boiler.

At the same time, the choice of a compact model should not be made only based on the volume indicator. The power of the TEN is also important, heating time, dimensions, installation orientation, the location of the pipes and the conditions of connection to the water supply and electricity network. It depends on these characteristics, how conveniently the boiler will work in your room.

We will analyze it below, for which tasks it is enough 15 liters, where a compact water heater will be especially convenient, what needs to be taken into account before installation and in which situations it is better to immediately choose a larger volume model.

Where is the volume? 15 liters are enough without permanent restrictions

Water heater on 15 liters belongs to compact storage models, designed primarily for one local water distribution point. It is advisable to install it in the kitchen, in a small office, workshops, guest bathroom or in the country, where hot water is required for hand washing, dishes, products and other short household transactions. In such conditions 15 liters give a noticeably larger reserve, than very small models, but the appliance is still compact enough to be placed next to the sink.

Such a boiler works best with periodic consumption. Example, the user washes several plates, closes the water, and after a certain time opens the faucet again. There is no water distribution yet, TEN restores the temperature. Thanks to this, a small capacity can normally supply the kitchen during the day, if the water is not used in long continuous cycles.

For a shower, this volume should no longer be considered a complete solution. Heated water really mixes with cold, therefore, at the output, the user receives more than 15 liters of water at a comfortable temperature. However, the supply is still limited and strongly depends on the heating temperature, cold water temperature and flow through the mixer. For regular bathing, it is better to immediately consider a larger accumulative model.

What makes the 15-liter model convenient for the kitchen

In the kitchen, not only the amount of hot water is important, and the speed of its appearance. If the main boiler is located in the bathroom or boiler room far from the sink, every time you open the tap, you have to drain the water first, which cooled in the pipe. The local tank is installed next to the point of consumption, therefore hot water arrives much faster. For a large private house with long pipelines, this is sometimes the main reason for installing a second small water heater.

Fifteen liters give a certain reserve when washing dishes by hand. If the user closes the faucet while soaping the dishes and does not keep the water constantly open, this volume is often enough for a normal household cycle. For a large family without a dishwasher, where many pots and pans are washed by hand every day, the capabilities of a compact tank may not be enough.

Another advantage – dimensions. The boiler can be placed inside the kitchen cabinet, above the sink or on the adjacent wall, if the specific model allows it. However, the free space must be measured together with the siphon, filters, cranes and other communications. A small body does not guarantee, that it will easily fit into any closet.

It is especially important not to confuse the models for the upper and lower location. At the boiler, intended for installation under the sink, nozzles can be located on top, while in the version for installation above the sink, they are directed downwards. It is not possible to arbitrarily turn the case over, unless the manufacturer has expressly provided for a universal provision.

For the office and cottage, not only the volume is important

In the office, a compact boiler often works for a washroom or a small kitchen for staff. here 15 liters can be quite a practical volume, if many people do not use hot water at the same time. When selecting, it is important to take into account not the total number of employees, and the real intensity of water extraction. Ten people, who wash their hands several times a day, create a completely different load, than the constant washing of dishes after a large team dinner. In the catalog Bull Bull it is advisable to compare compact models not only by volume, but also by power, dimensions and permissible method of installation.

In the country, you also need to think about seasonality. If the room is not heated in winter and the temperature can drop below zero, water from the boiler and pipeline must be drained according to the manufacturer's instructions. Freezing water inside the tank or fittings can damage the equipment. Therefore, even during installation, it is necessary to provide a way to completely empty the system, and not to solve this issue already before the frosts.

What to check before installing a compact water heater

The installation site is checked first. It is necessary to know not only the width and height of the free zone, but also the depth of the case together with the connections. Inside the kitchen cabinet, the boiler should not press against the siphon, garbage container or filtration system. The technician also needs access to the valve, TEN and connections for future maintenance.

Next, the power is evaluated. It is she, together with the volume, that affects that, how quickly the water heats up again after use. Two models on 15 liters may have different water preparation times, therefore, it is better to look at the passport characteristics of a specific product. For an office or kitchen with frequent short water distributions, the speed of temperature recovery is often more important, than additional electronic functions.

• check the dimensions of the body and the direction of the nozzles;
• clarify, where installation is allowed – over the sink, under it or in both positions;
• compare the capacity of the heating plant with the capabilities of the power grid;
• leave access to the safety valve and service elements;
• provide for a separate water shut-off for maintenance;
• for a seasonal room, ensure the possibility of completely draining the water.

The electrical part needs the same attention, as in larger boilers. Compact size does not mean, that the device can be connected to a random extension cord without checking. A working line is required, grounding and protective automation in accordance with the capacity of the equipment and the manufacturer's requirements. This is especially true in the kitchen, because a kettle is often working nearby, microwave oven, fridge, dishwasher and other consumers.

At the cold water inlet, a protective assembly with a safety valve provided by the manufacturer is installed. Water expands when heated, therefore, a small tank also needs pressure control, as well as the great one. Block the outlet of the valve or put fittings between it and the tank, which cuts off protection, can't.

The first launch is performed only after filling. First, open the cold water supply and the hot water tap on the faucet. After the air comes out and a steady flow comes out of the faucet, the tank is considered full. Only then is the device connected to the power grid. It's simple, but an important requirement, because the heating element should not work without water.

When should you switch from 15 liters to a larger volume

The main sign of insufficient mileage – the user regularly uses up the entire supply and is forced to wait for reheating. If it happens not occasionally, and almost every day, the problem is usually not solved by raising the temperature. It is more rational to choose a larger capacity, especially when several people use the hot water in a row.

For the kitchen, a larger volume should be considered, if there is no dishwasher in the house, often cook and wash a lot of large dishes. In the office, the need increases with the number of users and the duration of water separation. In the country, a larger tank may be needed, if one system should provide more than just washing, and other points.

Boiler on 15 liters is most logical precisely as a local source of hot water. It takes up little space, не вимагає зберігати великий запас і добре справляється з короткими побутовими задачами. Якщо його можливості співпадають із реальним режимом використання, компактність стає перевагою. Якщо ж від приладу очікують роботу як від великого сімейного бойлера, краще одразу перейти до іншого об’єму, а не компенсувати нестачу постійним очікуванням нагріву.
