Questions
Closed heating circuit: circulation pump → flow 70 °C → heating coil → return 50 °C. Copper arrows show the water's flow direction; the output follows P = q · c · ΔT.
§ 01 — What you can do here
Six tools from hydraulics to installation — for students, fitters and installers.
Hydraulics, heating, pumps, expansion and drinking-water hygiene — the trade's physics and rules in one place, with formulas and worked examples.
Water velocity, heat output, pipe content, pump power, heating time and expansion — enter the figures and get answers in seconds.
Checklists and process templates for installation, commissioning, balancing and documentation — ready to follow on the job.
Practise the syllabus: flow and heat, pumps, expansion and drinking water — mixed or by topic, so you're ready for the exam.
Pipes, fittings and valves, heating and hot water, insulation and supports — datasheets with generic, cited key figures.
A Claude-powered assistant focused on plumbing & HVAC. Ask about flow, heating, pumps, expansion or the regulations — the answer streams live.
§ 02 — Read now
Flow velocity from flow rate and diameter
Flow, temperature difference and transferred power
Water volume from geometry
Flow, head and efficiency
§ 03 — Tools
Enter the flow and the temperature difference between supply and return — and get the transferred heat output and the mass flow in seconds. The formula P = q · c · ΔT uses the material constants of water near room temperature.
Open calculators→Example · Heat output from water flow
§ 04 — Next step
The AI assistant can size flow and heating, explain pumps and expansion, and help with drinking water and regulations. Write to it as you would to a colleague.
