Tips on energy saving

Quick Tap function
▶ Fully open your hot water tap for at least 3 seconds. This ignites the
boiler.
▶ Turn hot water tap to fully closed.
1)
▶ Wait up to 30 seconds as the boiler continues to prepare hot water.
▶ Open your hot water tap; hot water is available
On average, 3.5 litres of water can be saved when using the Quick Tap
function.
Water saving varies depending on user behaviour, pipework design and
the time of year, for example, if Central Heating is on during the winter,
DHW will heat up quicker than in the summer, reducing the potential for
water saving. Savings are calculated based on average mains water
pressure, a heat-up time of 30 seconds and close proximity of the tap to
the boiler
Heating economically
The appliance provides a high level of comfort whilst keeping fuel
consumption and the environment effects as low as possible.
The appliance is controlled in such a way that it delivers heat at the
correct rate and only if there is a clear demand from the system.
Central heating systems with thermostatic radiator valves
With modern heating systems set around a 20 °C heat loss, the optimum
setting for a condensing boiler will be approximately 65 °C for the central
heating temperature. This is to ensure a return temperature of less than
52 °C.
The system must be balanced correctly and the radiators may need
upgrading. This allows the boiler to condense as much as possible for the
central heating system.
The temperature of each room can be set individually (except primary
room with the room thermostat) using the thermostatic radiator valves.
Room thermostats
Reducing the setting of the room thermostat by 1 °C can reduce fuel
consumption by up to 10%.
New control systems
Upgrade your heating control system if necessary with the latest
equipment available.
Roof insulation
Around 30% of the heat loss from a property is through the roof. Replace
any old insulation with new insulation, preferably of around 200mm
thickness or more.
Window frames
Single glazed windows, particularly those with steel frames, can lose a
great deal of heat. Consideration should be given to replacement with
PVCu or wooden framed double glazed units.
Radiators
If a radiator is sited underneath a window, its performance will be
affected if the curtains are allowed to drape over the radiator. Shelves
fitted above or in front of the radiator should also be avoided.
1) If the hot water reaches the set temperature before 30 seconds has elapsed, the
boiler will stop firing
2) Hot water is available at the boiler. Delivery time to the tap will vary on the
pipework design and tap distance from the boiler

It is advisable to manually adjust all thermostatic radiator valves every
2‒3 months to prevent them sticking. Ensure radiator valves are
correctly set and not damaged.
Draughts
Try to ensure that draughts around doors, windows, letter boxes and
keyholes etc. are reduced by using a suitable draught excluder.
2)
Air vents!
▶ Do not block or seal any air vents that are installed to ensure that the
Curtains
Lined curtains, or heavier full length curtains can provide excellent
insulation. However, always ensure that the curtains do not drape over
radiators.
WARNING
appliance operates safely.
