EWS sizes a borehole field. Planeto sizes the same borehole field — SIA 384/6 depth, temperature profile, thermal resistance — then wires it straight into your network design, heat pump sizing and financial report, in a browser, with no per-PC license.
You already know how to size a borehole field in EWS. Planeto runs the same core physics — then keeps the result connected to the rest of the project instead of leaving it in a standalone file.
Required borehole length, inlet/outlet temperature and heat extraction rate, calculated in hourly time steps — the same core calculation as EWS.
Place boreholes freely on the plan rather than a fixed grid, with no cap at 600 — Planeto scales to district-sized fields.
Model borehole fields hydraulically linked to TABS, cooling ceilings or ventilation, without a heat pump in the loop.
Configure antifreeze/fluid properties and get average seasonal performance for the borehole-to-heat-pump system.
Bring in heating/cooling demand from a building or district instead of typing a load profile by hand.
Get a report of boundary conditions and results — in Planeto, as part of the same document as the rest of the project, not a separate PDF.
EWS is a single-purpose Windows tool for one borehole field at a time. Planeto is where that same borehole field becomes one heat source inside a full district energy project.
Your sized borehole field becomes a heat source in the same model as the pipe network, hydraulics and other sources — including 5G DHC loop and meshed configurations. EWS stops at the field. Planeto keeps designing the network around it.
Only in Planeto
EWS has no cost calculation. Planeto turns the same borehole field into CAPEX/OPEX estimates and a bankable, re-runnable financial report, ready for technical-advisor scrutiny.
Only in Planeto
No Windows install, no single-workstation license, no paid version upgrades. Planeto runs in the browser, updates automatically, and lets your whole team work on the same project.

EWS, developed by Huber Energietechnik AG, is a Windows desktop program for sizing geothermal borehole heat exchangers (Erdwärmesonden). It calculates required borehole depth, inlet/outlet temperatures and heat extraction rates in hourly time steps, and can size borehole fields according to the Swiss norm SIA 384/6.
Yes. Planeto is a browser-based alternative that sizes geothermal borehole fields — with no installation, no per-PC license and no fixed borehole count limit — and connects that sizing directly to district heating network design, heat pump sizing and financial modelling in the same project.
Planeto's geothermal borehole design module calculates required borehole depth, temperature profiles and thermal resistance for vertical borehole fields, built for the Swiss and European engineering practice that SIA 384/6 and VDI 4640 are based on.
Yes. EWS Pro caps a borehole field at 600 boreholes. Planeto has no fixed limit, which matters for large district-scale or 5G DHC borehole fields.
In Planeto, a sized borehole field is a heat source object inside the same model as your network layout, pipe sizing, heat pumps and financials — so changing the borehole field updates the network hydraulics and cost report automatically, instead of re-importing results between separate tools.
We needed a solution that could support our design decisions and optimize projects from the ground up. We're finally able to do just that—saving time, improving accuracy, and ensuring we make the best possible impact with each project.
I can calculate different variants of district heating and cooling networks 5 times as fast and write the corresponding reports. This helps my customers to make well-founded decisions without having to repeatedly place new orders for variants.
