This public calculator does not recommend a manufacturer, catalogue item or equipment model. It sends declared inputs to the protected Adelphos calculation service and never falls back to browser arithmetic.
No account or Adelphos project is required. No HTML report is offered. The downloadable report is the Adelphos-branded PDF returned by the protected report service.
How does the Hot Water Cylinder Sizing Calculator work?
Record each bath, shower and other draw-off, including quantity, draw volume, use temperature and coincidence, then add the cold-feed temperature, storage temperature, recovery time and available heat input.

Design information you need
Record each bath, shower and other draw-off, including quantity, draw volume, use temperature and coincidence, then add the cold-feed temperature, storage temperature, recovery time and available heat input.
Calculation result and PDF report
The result converts the declared draw-off demand into an equivalent stored volume and recovery requirement for design review. A successful calculation can also produce an Adelphos-branded PDF report.
Checks, limits and responsibility
This calculation is an aid, not a design approval. The user must verify every input, applicable standard, result and its suitability for the project.
How to use the Hot Water Cylinder Sizing Calculator.
The calculation follows four clear stages: gather verified information, enter the design inputs, calculate, then review the returned checks and report.
1. Gather the source information
Record each bath, shower and other draw-off, including quantity, draw volume, use temperature and coincidence, then add the cold-feed temperature, storage temperature, recovery time and available heat input.
2. Enter the design inputs
Use consistent units and declare every required assumption. This calculator does not silently replace missing required values with convenient engineering defaults.
3. Run the protected calculation
Submit the form to the Adelphos calculation service. The calculation performs no fallback arithmetic in the browser and returns only the public result needed for review.
4. Check the result before use
The result converts the declared draw-off demand into an equivalent stored volume and recovery requirement for design review. Check the result against the coordinated design, current project requirements and competent-person review.
Hot Water Cylinder Sizing Calculator searches covered by this page
Toolbox research groups this page with related searches for hot water cylinder sizing, hot water cylinder sizing chart, hot water tank what size and hot water cylinder size calculator. The sections above explain the common design basis, while the calculator uses the actual declared inputs rather than a chart-only or product-led answer.
The user is responsible for verifying all inputs, assumptions, standards, selections, outputs and suitability, and for obtaining competent-person review. Adelphos accepts no responsibility for decisions made using this calculation.
Hot Water Cylinder Sizing Calculator questions and answers.
What size hot water cylinder do i need?
Cylinder storage depends on the actual draw-off events, their volumes and use temperatures, cold-feed and storage temperatures, diversity, recovery time and available reheat power. The calculator converts those inputs into equivalent stored volume and a reheat requirement; it does not recommend a product.
What size hot water tank for my home?
Household size alone is not enough. Record the baths, showers and other peak draws, their simultaneous use, target temperatures and recovery expectation, then review the calculated storage and reheat duty with a competent designer and the current project requirements.
