Adelphos workflow
Provide the brief and source information, confirm the required output, run the applicable named tools, then review the result and resolve assumptions before use.
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.
Frequently asked questions.
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.
