A feature of boilers for heat pumps. What is the difference and key advantages?

The heat pump is modern and Energy efficient The source of heat, which works in completely other modes, how Traditional boilers. For the organization hot water supply The obligatory element of the system is tank (boiler) indirect heating. But it is important to understand: Boilers, Suitable for solid fuel or electric boilers, Ineffective for heat pumps.

Why standard boilers for boilers are not suitable for heat pumps?

At first glance it may seem, What is anyone The boiler of the indirect heating Able to work with any heat source - Solid fuel boiler, electric boiler or heat pump. But this is not so. The reason lies in principle of operation of the heat pump And his specificity energy efficiency.

1. Operating temperatures

  • Solid fuel boilers Produce water with temperature 70–90 °C.

  • Electric boilers - usually 60–80 °C.

  • Heat pump works in a completely different mode - it Optimum feed temperature amounts to 35–55 °C.

When in the tank is installed Standard heat exchanger (zmeevik) with a small surface area, He works well with high boiler temperatures, But it becomes small -defective With a heat pump. That is, at low supply temperature, heat is simply does not have time to be transferred into the water.

2. Heating speed

In standard boilers for solid fuel or electric boilers, water heating is designed for high feed temperatures - usually 70–90 ° C. Such tanks are designed for rapid and powerful heating, Therefore, the heat from the high -temperature boiler is transmitted to water very efficiently. But when working with a heat pump, the situation is completely different: The heat pump operates at low temperatures (35–55 °C), And the standard coil of the boiler simply does not have time to give a sufficient amount of heat. Because of this, the heating time of water can increase by 2-3 times compared to the operation of the boiler. As a result, the user is faced with constant hot water deficiency, especially in peak hours of consumption, And the heat pump is forced to work longer and with increased load, which reduces its effectiveness and reduces the resource.

3. The load on the system

Small heat exchanger In the standard Boyler Makes Heat pump work in peak modes longer, Trying to compensate for insufficient heat transfer. This leads to several negative consequences:

  • Reducing energy efficiency - electricity costs are growing, because compessation It works longer.

  • Fast wear of equipment - the load on compessation and other elements of the system.

  • Frequent on and off - the number of working cycles increases, which additionally reduces the resource heat pump.

Thus, Using the standard boiler actually overloads the system and reduces its effectiveness.

4. Problem “The wrong boiler”

Many users mistakenly think, what can be connected to heat pump Any available boiler for the boiler. In fact, such an attempt leads to a number of problems:

  • The water in the tank heats up slowly or remains barely warm, especially in the winter period, When the need hot water increases.

  • Emergency heat pump modes -due to overload of the equipment may work protection or frequent inclusion/off occur.

  • Discomfort for the user - Disadvantage hot water In peak hours, makes the system uncomfortable and ineffective.

Thus, An attempt to use “ordinary” boiler leads to loss of comfort and increased electricity consumption.

The importance of a coil in a boiler for a thermal pump

Zmeevik (heat exchanger) - This is a key element of any Indirect tank. It is through him warm from heat pump Transmitted water In the tank. His size, form and material Determine Heating efficiency, The speed and durability of the system.

Square of the coil

For heat pumps critically important Large area of ​​heat exchanger. The larger the area, the more effective the transmission occurs heat, Even at low feed temperatures. Standard Boilers for boilers They have small ones Snakes, designed for the high temperature of the coolant, But when working with heat pump They just can't cope: Water heats up slowly, and the pump works in peak mode, What reduces it resource and efficiency.

Shape and construction

Optimally designed zmeevik Provides maximum contact coolant with water. The most effective Spiral or multi -prime structures, which evenly warm up the entire volume of the tank. Also important The distance between the turns: It should allow free water movement for uniform heating.

Production material

Material Snake defines not only heat transfer, but also durability grandmother:

  • Copper - An excellent thermal conductor, resistant to corrosion and long -term heating/cooling cycles. Ideal for heat pumps, providing high heating rate and efficient operation at low temperatures.

  • Stainless steel - more resistant to aggressive water, But thermal conductivity is lower, than cops. Used in some tanks for increased resistance to corrosion and mechanical loads.

Why is it critical for the heat pump?

  • Large and high quality zmeevik provides rapid water heating with low -temperature supply from Tn.
  • Reduces the load on compessation, Raises Energy efficiency and extends the service life of the system.
  • Provides Stable hot water temperature Even in peak hours of consumption.

Thus, The right choice Snake and the material of its manufacture is a key factor when designing a hot water supply system at the base heat pump. Insufficiently large or made of low -quality material heat exchanger makes the entire system less effective and reduces the life of the equipment.

What is the difference between boilers for heat pumps?

Boilers for heat pumps differ from standard tanks for boilers not only external design, but also constructive and functional features, who make them as effective as possible when working with low -temperature sources of heat.

An enlarged coil

In specialized tanks, area heat exchanger Significantly more - sometimes 2-3 times the size of standard models for boilers. Big zmeevik Allows heat from heat pump It is more quickly and more efficient to be transmitted to water in the tank even at a low feed temperature. This is critical for heat pumps, Since they work in low -temperature mode, and the small heat exchanger could not provide sufficient speed of water heating.

Optimized area of ​​heat exchanger

Not only size, but also The configuration of the coil importance. Optimally designed heat exchanger provides maximum contact coolant with water in the tank, which allows you to transmit heat as efficiently as possible even with a slight temperature difference between coolant and water. Thanks to this boiler stably maintains the desired temperature of hot water and allows heat pump work in optimal mode.

Work in low -temperature modes

Specialized tanks are designed, to effectively work at low feed temperatures heat pump (35–55 °C). They do not lose performance, do not overload the system and provide quick and stable water heating. This guarantees comfortable use of hot water even in peak hours of consumption.

Advantages for the user and system

Thanks to these constructive features Boilers for heat pumps:

  • Provide Stable hot water supply at any time of the day.

  • Raise The energy efficiency of the system, because Heat pump works in comfortable mode and is not overloaded.

  • Extend the resource of the equipment, Reducing the number of cycles of the VCL/Off and wear compressor.

Thus, usage specialized boilers - A prerequisite for the effective and durable operation of the hot water supply system at the base heat pumps.
