Direct water heating
and cylinder |
| |
 |
|
With a direct cylinder the water is heated directly
via an electric immersion element, or from a remote heating
boiler, which has been designed for water heating only, for
example a copper coal fired back boiler.
This is the simplest form of water heating, it gets its name
from the fact that the water drawn from the hot taps has been
directly heated via the boiler, i.e. the stored water has
been through the copper back boiler or around the immersion
coil and is then used for bathing. |

Bearing in mind this water has been stored in
the attic then heated and stored in the cylinder, this water
should not be consumed.
This system is ideal for rented accommodation due to is low
maintenance requirement, or partially used properties where
frequent draining and re filling by the owner is required. |
