Heat pump for DHW and ventilation

operation, advantages and savings

Nowadays, energy efficiency and indoor air quality are key aspects to improve our well-being and reduce environmental impact. For this reason, heat pumps for ventilation and DHW production are positioned as a technological revolution in this sector.

In this article, you will discover how heat pumps that combine ventilation and domestic hot water (DHW) production represent an innovative and efficient solution for modern homes. We will explore in detail how these systems work, their key advantages and how they can transform your home into a more sustainable, healthy and economical space. In addition, we will introduce you to the AQ VENT, a state-of-the-art system that redefines quality and efficiency standards.

What is a heat pump for ventilation and DHW?

Unlike conventional heat pumps, equipment that combines ventilation and domestic hot water (DHW) production takes advantage of the air extracted from inside the home to reuse its thermal energy before being expelled outside. This process allows:

Ensure constant renewal of indoor air, improving the environmental quality of the home.
Using air energy to heat water efficiently.

Advantages of heat pumps with ventilation

Double function: Ventilation and DHW

These systems not only provide a constant flow of fresh air, but also generate hot water simultaneously, which optimizes energy consumption.

Indoor air utilization

Air extracted from humid areas such as bathrooms and kitchens, which is normally lost, is reused to recover its heat, thus reducing energy waste.

Energy efficiency

These devices achieve high coefficients of performance (COP), generating up to four times more energy than they consume. This translates into lower electricity bills.

Healthy ambient

Constant air renewal helps eliminate contaminants such as dust, bacteria and allergens, creating a cleaner and more comfortable space.

Photovoltaic compatibility

The possibility of integrating these systems with solar panels allows maximizing savings and making the most of renewable energy.

How does a heat pump work for ventilation and DHW?

Indoor air capture

The unit extracts air from humid areas such as kitchens or bathrooms. This air is full of thermal energy.

Heat recovery

It uses a heat exchanger to transfer heat from the air to the Domestic Hot Water production system.

Cold air expulsion

The cooled air is expelled outside through a duct, improving interior comfort.

Production & storage

The recovered heat is used to heat the Domestic Hot Water, which is stored in a high-quality tank.

FAQ about ventilated heat pumps

1. Does it work well in cold climates?

Yes, these systems are designed to operate efficiently even in low temperatures, taking advantage of heat recovery technology to maintain their performance.

2. How much can you save?

On average, you can reduce energy consumption by 50-80% compared to traditional systems, depending on usage and home conditions.

3. Are these heat pumps compatible with existing homes?

Generally yes, as they can be retrofitted into most existing installations, although a professional assessment is recommended.

How is it different from a conventional heat pump?

Unlike conventional heat pumps, systems that combine ventilation and domestic hot water (DHW) production offer unique benefits. The following table compares their key features:

Characteristics	Conventional heat pump	Heat pump for ventilation and DHW
Main function	Air conditioning or DHW production	Simultaneous ventilation and production of DHW
