Once water is heated, it is stored in a hot water storage tank for distribution to radiators and taps.

Combination (combi) boiler: these boilers supply hot water on demand, and do not require a hot water storage tank. They are ideal for small buildings, such as apartments.


NGfL CYMRU GCaD


Hot water can also be provided by localised boilers, such as the one shown right.

Note that the cover has been removed to show the inside of the boiler.

Wash hand basin, taps, waste pipe and bottle trap.

W.C. cistern and macerator. The macerator can be fitted to W.C.s installed in basements, and will reduce solids to a liquid before waste enters a foul drain.

Plastic foul drain pipes waiting connection to W.C. s. Note the slope of the pipe, known as the “fall.” This varies, depending upon the diameter of the pipe.

To reduce environmental impact in buildings, sustainable energy can be used. The above picture shows a solar panel, one of a bank of several on the roof of a new building.

Rainwater harvesting can be used to collect rain water for use in W.C.s.

Advantages are lower costs of water during the lifetime of a building, less reliance on mains water and reduced environmental impact.

A disadvantage is higher costs of equipment during construction.


NGfL CYMRU GCaD


Rainfall is collected via the building’s gutters, and is directed to a storage tank.


NGfL CYMRU GCaD


The water is then pumped through a filter (left) into a header tank (shown right), ready for use.


NGfL CYMRU GCaD


Should a dry spell of weather affect collection of water, then pumps can draw water supplies from the mains.
