Hot water supply
As with all mains fed systems, the flow rate of water
obtainable from individual taps will vary in relation to the
number of taps operating simultaneously, and will depend
upon the cold mains supply available to the property.
Therefore, in order to avoid excessive starvation of flow
to individual taps, flow balancing may be required by the
use of proprietary constant volume flow regulators or
Ball-o-Fix valves.
Hot water systems
Taps and valves
Hot and cold taps and mixing valves used with Greenstar
Highflow CDi appliances must be suitable for operating at a
mains pressure of up to 10bar (150psi) and temperatures
of 65°C (150°F).
Showers
When a loose head shower with a flexible hose is used over
a bath or shower tray, the hose must be fixed so that the
head cannot fall closer than 25mm (1in) above the top edge
of the spill over level of the relevant bath or shower tray.
Alternatively, the feed pipes to the shower should
incorporate a double check valve assembly or a check valve
and vacuum breaker.
With fixed head showers no provision is necessary.
The use of a thermostatically controlled shower will give
added comfort and safeguard against high hot water
temperatures.
Bidet
The supply of hot and cold water mains direct to a bidet
is permitted provided that the bidet is of the overrim
water feed type. The outlet(s) should be shrouded and
not have any temporary hand held spray attached. No
other anti-syphonage arrangements are necessary.
Use in hard water areas
As the maximum temperature of the domestic hot water
heat exchanger is limited by the electronic control circuit,
there is normally no need for water treatment to prevent
scale accumulation.
In areas where exceptional water conditions prevail,
consideration may need to be given to the fitting of a device
capable of preventing scale. In such circumstances the
advice of the local water authority should be sought.
Warranty
Worcester Greenstar Highflow CDi appliances are offered
with a full 2 year guarantee* on parts and labour, a 10 year
warranty* on the primary heat exchanger and a 5 year
warranty* on the plate heat exchanger. Ongoing service and
maintenance contracts can be arranged through the
Worcester Customer Service Department.
*Subject to conditions.
