Hot water in the country - one of the indicators of comfort. Most often it can be available only if the water heater. Today such equipment is quite a lot, so decide which device to choose will be easy. Suffice it to choose its technical parameters under operating conditions, and read user reviews.
Each heater can only be effective in certain circumstances. These include:
boiler capacity
This is an important characteristic which should be taken into account. Before you choose which to buy a boiler need to calculate its capacity based on the rate of consumption per person. To properly calculate the volume of the boiler is necessary to use the following formula:
V = Q × n × (t1- t2) / (t3- t2).
| Q | volume of the hot water per person per minute; |
| n | the number of users; |
| t1 | required water temperature from the tap; |
| t2 | temperature of cold water in the pipeline; |
| t3 | the temperature of the heated water in the container. |
Typically, the temperature is distributed as follows:
| t1 | 35 - 40 ° C |
| t2 | 9 - 18 ° C |
| t3 | not more than 65 ° C |
Expert Reviews indicate that the warm water in the shower is consumed to 6 liters per minute per person, dishwashing - 3 l / min. It remains to complete the formula and calculate the correct volume of the tank.
types of heaters
They differ in several characteristics:
- on the principle of action - storage and flow, pressure and non-pressure water heater;
- Fitting according to embodiments is typically a wall or floor units;
- heaters used in form of energy may be electric, gas, diesel, coal, combined.
Savings
This apparatus with termozaschischennym tank which ensures long preservation of the preheated water temperature. Ten or spiral can be switched on to heat due to the temperature sensor and the control unit. Electric boiler is equipped with drives of different sizes.
For a small family and limited applications, such as washing dishes, only a small boiler. When using the heater, not only for domestic purposes in the kitchen is better to choose the maximum amount of storage that is just suitable for villas conditions.
Reviews truckers usually confirm the reliability and ease of use of the storage boilers.
flowing
Small size due to the absence of the tank fit well in a small square room. Instantaneous heater quickly bring water to the desired temperature and off when the water is turned off.
This design greatly facilitates installation, saves space in the room with a small area, removes the question of the strength of the walls. Furthermore, flow boilers economical in terms of power consumption unlike analog with capacitance.
These inexpensive devices are usually designed for a single point of distribution. For a large family better to choose a storage device or to take a more expensive and powerful flow-through apparatus.
pressure
To the country, where there is no central water supply is better to take pressureless model. She had an open container in which water can be pumped manually. This boiler is simple to install and use, is inexpensive. But its functionality is usually limited to a kitchen and a summer shower. For temporary residence in the summer that's enough.
Gravity
When using the garden as a seasonal dwelling or for permanent residence will need pressure boiler. is he mounted in the riser and will be able to provide all the hot water needs - from washing dishes in the kitchen to a hot bath set.
Anchoring
A small flow heater or boiler with wall installation does not greatly increase the load on the wall.
Installation of heavy accumulating device requires special attention to the strength of the walls. If they are not strong enough to withstand the heavy tank without the threat of collapse of the structure, it is better to prefer a wall heater floor.
Reviews have noted this boiler is easier to install and more resistant. But it will take more space and may require a separate room for the installation for large dimensions.
Heat
For suburban application should take into account possible sources of supply for the boiler.
Electric
This water heater is still the most popular. Apparatuses with electrical heating element may be performed in the storage, flow, wall and floor performance. All of them are easy to install.
In most cases, the connection to the power supply through the normal household socket. But flow electric water heater with a large power consumption will need a separate cable, which will provide a secure connection.
Gas
In the absence of reliable electrical wiring, with regular interruptions in the power supply or in order to save better to choose the appliance with the gas burner. This may be a flow model or the same device with a storage tank.
The main drawback of the gas system - the need for expert calls for installation and maintenance. Otherwise, use of such a device is unsafe.
Other sources of heat
A possible embodiment could be to give the device a solid-diesel or heating water. Such boilers occupy a mid-price segment and costs of ownership between electric and gas. Their features:
- They need a separate room for the installation;
- have stretched communication;
- require more complex and time-consuming installation works;
- much time is spent on maintenance.
These boilers provide hot water several connection points. A good choice for the garden, where there is no stable electricity and gas distribution network.
Ranking of the best models
The review presents Electric storage water heaters, which are many in the country.
