Stiebel Eltron UK is marking 50 years of heat pump manufacturing by adding new models to its hpnext series, launched in June the previous year. The aim is more choice for homeowners and a wider fit across property types and projects.
What’s changed
- The HPA-O 13.2 Trend HC 230 replaces the older WPL-A 25 ACS models, bringing hpnext features to that size in both the Trend and Plus ranges.
- Trend range: new 5, 7 and 13 kW 230 V units join the original 10 kW 230 V model.
- Plus range: a new 10 kW 230 V model joins the existing 7 kW 230 V, alongside a 10 kW 400 V model to sit with the 13 kW 400 V unit already available.
- All four Plus models will be offered in white as well as anthracite later in the year.
- A lightweight SBB 200 Trend hot water cylinder has been added as an accessory and as part of reworked heat pump packs that bundle compatible parts into one solution.

About hpnext
The hpnext series covers new air and ground source heat pumps plus integrated internal air source units that also provide mechanical ventilation with heat recovery (MVHR). Stiebel Eltron says these are the quietest heat pumps it has made. For installers, the wider size range is meant to simplify specification across different jobs.
