What is a ‘combi’ boiler?
A ‘combi’ or combination boiler is a high efficiency water
heater and a central heating boiler combined (hence the name)
within one compact unit. Water is heated directly from the
mains eliminating the need for a hot water storage cylinder and
the associated cold water storage cistern in the roof space.
Because your hot water is delivered to your taps or shower at

important ways. Firstly, many of the components of the heating
and hot water system are built into the boiler itself, making
it quicker and easier to install. Secondly, it doesn’t need a

please visit www.worcester-bosch.co.uk
Heating controls – what are the differences?
The majority of heating systems have at least two controls: a time clock or programmer and
room thermostat. In fact, this is the minimum level of electrical controls specified by the
Building Regulations for the installation of all boilers and is a legal requirement.
• A timer or programmer operates the heating system to turn on for set periods of time.
Controls can be either wall-mounted near to the boiler or attached to the fascia panel of
the boiler. It will take at least 30 minutes for your home to reach the desired temperature
when the boiler fires up, depending on insulation levels and the outside temperature. The
main difference between the two controls is a timer will operate the system at the same
times every day whilst a programmer allows different heating times for different days of
the week to suit your lifestyle.
• A room thermostat controls the air temperature and is usually positioned in the hall or
landing. The thermostat can be analogue or digital. It should be sited away from direct
sunlight and clear of curtains and furniture. As a guideline, your thermostat should be set
between 18ºC-21ºC for comfort temperature and 10ºC-12ºC for economy temperature.
• A programmable room thermostat allows you to programme the temperature levels to
alter according to different times of the day and night. When programmed correctly this
type of control prevents the system having to heat the house from a “cold start”. The
control always maintains a temperature within the property (as decided by the user).
This ensures that the boiler is only ever “topping up” the temperature in the home.
• An outdoor weather sensor measures the air temperature, and software on the
Heatslave II boiler adjusts the heating flow temperature according to outside temperatures.
16
Digital and wireless programmers and room thermostats
Digital plug-in 7 day twin channel programmer (for use with Greenstar Danesmoor System,
Greenstar Danesmoor regular and Greenstar Danesmoor wall-mounted models only)
• Plugs into the boiler fascia panel and offers 3 separate time periods for both
heating and hot water.
DT20 twin channel digital programmer (for use with Greenstar Heatslave II models)
• Plugs into the boiler fascia panel and is pre-set to current time, date and day
• Adjusts automatically in line with British summer time
• Three separate time periods for both heating and hot water
• Use either the built in pre-set programmes, or choose your own settings.
DT20RF digital RF thermostat with twin channel programmer
(for use with Greenstar Heatslave II internal models)
• Features simple set-up
• Set up to three different time periods a day
• Room thermostat provides the temperature control
• Benefits from no wiring required
• Twin-channel facility times the domestic hot water function.
DT10RF digistat (for use with Greenstar Heatslave II internal models)
• 24-hour programmable room thermostat
• Set different temperatures for up to six different time periods.
• No separate room thermostat is required
• Benefits from no wiring required
• Complies with Buildings Regulations Best Practice.
DT10RF optimiser (for use with Greenstar Heatslave II models)
• Sophisticated seven-day energy-saving device with the same features as the
DT10RF digistat
• Optimum start – calculates the time needed to activate the boiler to precisely
achieve the required temperature at the required time each day
• Set different temperatures for up to six different time periods for each day of the week
• As a radio frequency device, it offers the benefits of no wiring
• No separate thermostat necessary.
17
Intelligent controls
FR10 intelligent room thermostat (for use with Greenstar Heatslave II models)
• Intelligent room thermostat that enables load compensation
• Offers further energy savings compared to standard on/off controls.
(Load compensation means that, rather than just switching the boiler on and off, it will adjust the flow
temperature of the central heating water in line with set heating temperature requirements. The smaller the
difference between the actual temperature and the set-point temperature, the lower the flow temperature
from the boiler.)
Outdoor weather sensor (for use with Greenstar Heatslave II models)
• Measures the air temperature outside the home, enabling weather compensation software
built into the Heatslave II
• Offers further energy savings compared to standard on/off controls
• Intended to be used with a room thermostat and a programmer
Weather compensation means that the flow temperature of the central heating water is adjusted in line with
outside weather conditions. In cold weather the flow temperature is higher. In warmer weather the flow
temperature is lower. This saves energy and improves home occupier comfort.

user to select the temperature required
at the hot water cylinder. The controller
then automatically decides when to run
the pump to bring the energy from the
panels to the cylinder.
We also have a family of intelligent heating
controls that are compatible with Greenstar
boilers. Part of this new family is designed
to enhance the efficiency of Greenskies
solar water heating systems.

The Worcester CondenseSure –
eliminating the risk of
frozen condensate.
All condensing boilers produce condensate which has to be discharged
from the property. In the majority of cases, it will be possible to do
this internally, but in some circumstances the location of the boiler means
that the condensate pipe has to be routed externally or in an unheated
area, with the possible risk of freezing in extreme weather conditions.
The Worcester CondenseSure is an innovative solution to freezing
condensate that can be installed with any condensing boiler. Unlike
other products designed to prevent freezing, the CondenseSure
requires no electrical connection and has no moving parts.
The Worcester CondenseSure features and benefits:
• No power consumption – zero running costs
• No moving parts – no failure of components
• Can be installed in new and existing installations –
suitable for all Greenstar gas and oil boilers.
The Worcester Greenstar System Filter –
protecting your heating system.
NEW
Modern condensing boilers are precision engineered and designed to
run with a clean water-heating system. Over time, dirty system water
will develop, damaging a boiler and its components, causing failures,
shortening the life of the overall system and dramatically reducing the
efficiency of the boiler.
A highly effective solution
The Worcester Greenstar System Filter has been specifically designed
to combat the damaging effects of system debris and pollutants,
protecting the boiler and heating system for a fraction of its cost.
At the centre of its innovative design is a powerful magnet that removes
the magnetic debris that is present in the heating system water. The central
location of the magnet ensures that the debris is collected quickly and
retained. Any non-magnetic debris is caught by the twin-action cyclonic
The filter can be fitted under or away from
the boiler.
trap, maximising overall protection.
Greenstar System Filter features and benefits:
• Highly effective – safeguards the boiler against damage and can save
up to 6% a year on energy bills*
• Prevents blockages in radiators – a warmer home and quieter system
• Twin action – effective against magnetic and non-magnetic system debris.
*Independent research.
