Air-to-water heat pump outdoor unit in the garden of a detached house

Heat pump sales, installation and maintenance

For homes and businesses looking to cut heating bills, we calculate the right capacity, install the system and carry out seasonal maintenance.

In shortA heat pump is an electric system that extracts heat from outdoor air and transfers it into the building to provide heating, cooling and hot water. YOİ Mühendislik provides heat loss calculations, installation, commissioning, scheduled maintenance and breakdown service for air-to-water heat pumps.

About heat pumps

Heat pump efficiency depends on correct capacity selection, a well-insulated system and low-temperature emitters (underfloor heating, fan coil units). A poorly sized unit falls short on cold days or cycles on and off frequently, shortening its service life.

What we do

  • Heat loss calculation and capacity selection
  • Outdoor and indoor unit installation, hydraulic connections
  • Boiler and buffer tank integration
  • Commissioning and heating curve setup
  • Annual maintenance and efficiency check
  • Defrost, sensor and control board faults
  • Circulation pump and filter service
  • Hybrid operation with existing boiler

Frequently asked questions

Is a heat pump cheaper than natural gas?

It depends on electricity and natural gas tariffs, building insulation and unit efficiency. We provide an annual consumption comparison during the site survey.

Does a heat pump work with radiators?

It works, but since efficiency is highest at low water temperatures, underfloor heating or large-surface radiators are a better match.

When should a heat pump be serviced?

Once a year is recommended, preferably before the heating season.
