external to the boiler prior to requesting a service engineers visit. Should the problem be found to be other than with the appliance
we rese rve t he right to levy a charge for the visit, or for any pre ---arranged visit where access is not gained by the engineer.

The nature of all combination boilers is to heat up water directly from the incoming mains water supply directly through the boiler to
supply domestic hot water at the stated flow rates, (as shown in the boiler installation instructions), to achieve a 35ûC t emperature rise.
As the ambient temperature of the cold m ain varies during the s ummer and winter m onths it is likely in the colder winter months that
the flow rate will need to be reduced at the outlet taps to achieve the same temperatures achieved in the warmer summer months.
This is not a fault with the appliance but is relevant to the varying temperature of the incoming cold mains water supply.
