WATER HEATER LOCATION

All

mains pressure electric storage hot water systems have an ingress protection rating

DOT-X

of I PX4 making them suitable for internal or external installation.

The water heater should be placed as close as practicable to the most frequently used hot water

outlet point or points to minimize the delay time for hot water delivery. This will usually be the

kitchen tap. For installations where the distance between the water heater and the outlets is

considerable, a flow and return system can be used which minimize the waiting time for hot water

delivery.

It is recommended that the water heater is installed at ground or floor level. It must be installed

in a vertically upright position. The water heater must be accessible without the use of a ladder

or scaffold. It must not be installed in roof spaces.

Ensure the pressure and temperature pressure release (PTR) valve, front covers, thermostats

and heating elements have sufficient clearances and are accessible for service and removal.

The information on the rating plates must also be readable. Leave adequate distance above

the water heater (preferably the height of the water heater itself) so the sacrificial anode can

be inspected and replaced via the top cover.

The water heater must be installed in freestanding mode on a level and stable base.For external

installations, the water heater should be mounted on a concrete base at least 50mm thick or on

well seasoned, evenly spread hardwood slats with a thickness of at least 25mm. Ensure the

water heater does not stand on wet surfaces.
