Installing a Heat Pump into an Existing Heating System

The modern trend of rising gas and solid fuel prices makes integrating a heat pump into an existing heating system one of the most rational steps for homeowners. This allows not only for reduced utility costs but also ensures eco-friendly and automated heating.

How to integrate a heat pump into a ready-made heating system?

Installation of a heat pump (HP) into an existing system is performed by parallel connection to the current boiler via a buffer tank or a low-loss header (hydraulic separator). Air-to-water heat pumps are most commonly used for retrofitting as they do not require extensive excavation. A key efficiency requirement is adapting the system for low-temperature operation (optimally underfloor heating or increasing radiator surface area).

The operating principle of a heat pump is based on physical processes involving the change of state of the refrigerant. By utilizing free energy from the environment, the device provides the home with heat, domestic hot water (DHW), and even cooling during the summer period.

Key stages of heat pump integration

Upgrading an existing thermal network is a technologically complex process that must be performed according to building regulations and includes the following stages:

1. Technical Audit: Checking the efficiency of the current system and calculating the building's heat loss.
2. Engineering Design: Selecting the connection scheme (bivalent system where HP works alongside a gas boiler).
3. Equipment Selection: Determining the required HP capacity and buffer tank volume.
4. Installation Works: Installing outdoor and indoor units, connecting to the hydraulic circuit and automation system.
