How to choose a heating and circulation pump
Heating and water pumps covers circulation, water-supply and other types. If you choose by “biggest W”, you risk buying a JET where you needed Evosta/PICO. Choice starts with the job.
When you need circulation · flow and head · how to size power.
Circulation for heating
It moves the heat carrier around the radiator circuit. Examples: DAB Evosta 2 40-70/130 DN15, Evosta 2 DN25, Evosta 2 180 DN25, Evosta 2 SAN, Wilo Atmos PICO 25/1-4, PICO 25/1-6, DUCA GEX-C 25-80-130.
Water supply / JET
DAB JET 82 M — water delivery, not a radiator pump. Do not confuse by the word “pump”.
Connections
Unions/valves are often separate — e.g. Giacomini 1½×1″. DN from the card and the old pump label.
Typical mistakes
- JET in the heating circuit.
- “Bigger pump with reserve” without hydraulics — noise.
- Forgetting DN and installation length (130/180).
Short path
- Circulation or water supply?
- DN and installation length.
- Flow/head from the project or the old label.
- 2–3 cards (Evosta / PICO).
