This tool will allow you to create your own hydraulic scheme (heat, cold, air conditioning) quickly and easily, you simply have to select the symbol you want to use, drag and drop it in the desired position. Symbols: Valves: 2, 3 and 4-way, mixing, control, balancing, butterfly, gate, safety, overflow, non-return, thermostatic, pump, flowmeter, meter, flow switch, pressure gauge, air and dirty separator, drain, temperature probe, boiler, heat pump, indoor and outdoor unit, accumulator, inter-accumulator, heat and cold exchanger, collector, thermostat, radiator, underfloor heating, pressure reducer, filter, resistor, sleeve, tap, buffer tank, gas, solar panels, coil, oven, swimming pool, emitters. # BASIC Version # * You can create your scheme with the same symbols as the Version PRO * You can only work with a scheme although you can share it as an image, pdf or file * Once you create a scheme you will no longer be able to open another (they are not saved) # PRO Version # (1 - In-App Purchases) * You will be able to open, edit and save a scheme * Open in the following examples (link) ------------- * More examples: https://drive.google.com/drive/folders/1W6HFnDNsZAZonUlPn5tEPEnbZOuACjxN?usp=sharing

Verdict
The clearest difference is price: Electrical Engineering at Free against Hydraulic schemes's $0.99. Electrical Engineering also leads on ratings volume (12 vs 1). Hydraulic schemes's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). On rating, review sentiment, in-app purchases and monetization model there is nothing between them.

Electrical Engineering is free to download; Hydraulic schemes costs $0.99 up front. Electrical Engineering sells 7 in-app purchases, starting at $3.99 per month and Hydraulic schemes sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Hydraulic schemes holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Electrical Engineering has 12 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 71% of Electrical Engineering's written reviews are positive against 77% of Hydraulic schemes's.
Electrical Engineering ships an update every 2 months, Hydraulic schemes every 2 weeks. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
