The field of heat pump systems is constantly evolving. New knowledge and insights arise almost daily, and you want to apply that knowledge in practice as well as possible. As a professional, you are helped by the recently updated ISSO publication 98 'Air/water heat pumps in dwellings'.

ISSO publication 98 'Air-to-water heat pumps in dwellings' provides professionals with guidance on the design, implementation, delivery and management of individual air-to-water heat pump systems, with outside air and/or ventilation air as the source. The document is basically limited to one type of system: the heat pump for hot water generation for space heating and domestic hot water. Optionally, this device can function in combination with a central heating boiler and/or (optional) cooling.

New knowledge

The publication discusses three variants:

  • Application of a combination heat pump for heating, domestic hot water preparation and cooling for an individual system. Hot water generation can be either integrated or separate to the heat pump.
  • Application of a heat pump boiler.
  • Application of a hybrid heat pump.

The knowledge in the publication is now fully aligned with the latest insights and installation practice. In addition, the various types of air-to-water heat pumps, hybrid heat pumps and delivery systems have been added. There are also appendices on the selection and dimensioning of these delivery systems and developments in refrigerants.
