<p>A water heating arrangement and in particular a combined water heating/central heating arrangement is provided with an enhanced water heating facility compared with existing combined water heating arrangements. The water heating arrangement comprises a primary hot water circuit and a secondary cold water circuit with both circuits including water-to-water heat exchange means located within a storage tank containing intermediate temperature water. The combined water heating arrangement is designed for cylinder/airing cupboard, floor standing and wall mounted applications and consequently provides a siting flexibility not to be found in existing combined water heating arrangements.</p> |
