As we move toward a more sustainable world, homeowners are increasingly looking for ways to decouple their heating from fossil fuels. Stiebel Eltron has been at the forefront of this movement for over 50 years, and their current 2026 portfolio represents some of the most advanced “hpnext” technology available. Heat Pump Tech are proud to be a Stiebel Eltron Servicing partner, with years of experience working for and with their technology.
Whether you are retrofitting an older property or building a new home, choosing to use pure renewable sources for your heating needs is a significant step toward energy independence. Stiebel Eltron offers a diverse range of models designed to handle everything from mild coastal climates to freezing inland winters.
Air Source Heat Pumps (ASHP)
Stiebel Eltron’s air source range is divided into different “series” to cater to varying budget and performance requirements. The newest models utilize R290 (propane), a natural refrigerant with a very low Global Warming Potential.
1. The HPA-O Trend Series
The Trend range is designed for those seeking high efficiency at a competitive price point. These monobloc units are incredibly versatile and work well with both underfloor heating and traditional radiators.
- HPA-O 05.2 Trend HC 230: Ideal for smaller, well-insulated homes.
- HPA-O 07.2 Trend HC 230: A popular mid-range choice for standard family homes.
- HPA-O 13.2 Trend HC 230: Recently launched to replace the older WPL-A 25 ACS models, offering improved efficiency and quieter operation.
2. The HPA-O Plus Series
The Plus range offers higher flow temperatures (up to 75°C) and even lower noise levels, making them perfect for densely populated areas.
- HPA-O 07.2 Plus HC 230
- HPA-O 10.2 Plus HC 230
- HPA-O 13.2 Plus HC 400: A powerful 3-phase unit capable of handling larger residential loads.
Ground Source Heat Pumps (GSHP)
For those with the land space for boreholes or horizontal collectors, ground source heat pumps provide the ultimate in year-round stability. Because the ground temperature remains constant, these units operate with incredible efficiency regardless of the weather.
The WPE-I Premium Series
The WPE-I range features inverter technology, meaning the pump modulates its output to match your home’s exact heat demand.
- WPE-I 04 HK 230 Premium: Perfect for smaller new builds.
- WPE-I 08 HK 230 Premium: A robust solution for medium-sized homes.
- WPE-I 15 HK 230 Premium: Designed for larger properties requiring significant hot water and heating capacity.
