Depending on the wiring system within your property your installer/developer may
have provided an off-peak timer in the airing cupboard of your property.
If a device is fitted it must be set to the correct time and set to synchronise with the
off peak meter for correct economical operation. This should have been set when the
system was commissioned but any power cuts could have altered the correct time.
THIS UNIT SHOULD BE LEFT PERMANENTLY CONNECTED TO THE
OFF-PEAK ELECTRICAL SUPPLY AND NOT SWITCHED ON AND OFF
WHEN HOT WATER IS NEEDED.
INSTALLERS MAY ALSO HAVE FITTED AN ON-PEAK SWITCH WHICH
CAN BE USED WHEN REQUIRED TO PROVIDE A BOOST TO THE TOP
PART OF THE STORE ON DAYS WHEN A LARGE AMOUNT OF HOT
WATER IS REQUIRED.
Scale
The water in the store never changes and therefore
the immersion heater elements
will never scale up during the life of the product
.
As far as the water you use is concerned scale can be a problem in any of your
domestic products if the water is very hard in your area.
The PulsaCoil ECO Stainless appliance has been designed to inhibit the formation
of scale, but if it does become a problem you will notice a deterioration in the flow
rate at your hot taps. In this situation your service engineer can de-scale the product.
Building Regulations now require some form of scale inhibitor to be fitted in hard
water areas, and so scale is unlikely to be a problem if the scale inhibitor is operating
correctly.
