Heating Control Options - Worcester Greenspring CWi47 Technical And Speci?Cation Information

Efficiency that today's energy-conscious
homeowner demands.
Over the last few years boilers have become increasingly
efficient and, with condensing boilers already offering
typical efficiencies of over 90%, there is little scope for
significant developments in boiler efficiency.
But the one area of the system where we can help improve
performance even further is in the controls.
More effective controls can improve the overall performance
of your heating system, dramatically reducing the amount of
fuel you use – and the amount you pay.
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.
Dial and digital 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.

Control options
Worcester can offer you three different types of control
for use with 'combi' and system boilers. These range
from simple-to-operate mechanical timers and more
sophisticated digital programmers and room thermostats,
right up to a new generation of intelligent controls.
Whichever you choose you can rest assured that it is
designed to be easy-to-use to make sure you get the benefit
of being in full control of your heating and hot water.
