DOYMAfix® HP/O – Above-ground house entry for air-to-water heat pumps

Product overview

The DOYMAfix® HP/O is the first professional above-ground penetration fitting specifically for air-to-water heat pumps. Its innovative design enables the safe, quick, and clean installation of all connecting pipes and ensures an aesthetically pleasing wall transition with a high-quality surface finish.

Designed for cross-trade assembly (shell construction, plumbing and electrical), the system offers maximum flexibility in the construction process and is suitable for both new and existing buildings.

Advantages at a glance

The building entry point reliably ensures thermal insulation and meets the requirements of the German Building Energy Act (GEG), regardless of wall construction and thickness. In addition, the product guarantees airtightness and protection against splashing water, as well as tested sound insulation.

Technical characteristics and standards

DOYMAfix® HP/O complies with relevant standards: airtight according to DIN EN 13829, protection against splashing water IP44 according to DIN EN 60529 and sound insulation according to DIN 4109-2. This design ensures that the heat pump connections are integrated into the building envelope in accordance with standards.

Installation and assembly

Assembly is quick and ideal for collaborative installations involving different trades. The well-designed construction allows for safe routing and connection of cables without interrupting the thermal insulation.

The assembly processes are designed to integrate well into the construction schedule and minimize rework.

Adaptability to wall thicknesses

In its standard configuration, the DOYMAfix® HP/O is designed for wall thicknesses up to a maximum of 500 mm. For greater wall thicknesses, extendable intermediate segments are available, offered in sets of four, allowing for flexible adjustment beyond 500 mm.

Variants and accessories

In addition to the standard version, the DOYMAfix® HP/O is also available as DOYMAfix® Connect HP/O, offering additional connection options and system variants. Complementary accessories include intermediate segments for wall thickness adjustment and components for cross-trade installation.

Areas of application

The system is suitable for private residential buildings, apartment buildings, and commercial properties, and can be used in both new construction and renovation projects. Its universal compatibility means the service entry fits all common wall constructions.

Safety, insulation and appearance

The combination of standard-compliant airtightness, tested sound insulation, and protected splash water protection ensures long-lasting operational reliability. At the same time, the clean surface finish allows for an attractive wall transition that blends harmoniously into the facade.
