Heating curves are a well established concept used
when designing commercial heating and ventilating
systems, but have never been widely used or
adopted in the UK for domestic installations – OSO
now bring this unique and energy saving feature to
the UK in our termo range of electric boilers.
By correctly setting the heating curve software
contained in the E version of the Termo electric boiler
energy consumption can be reduced by up to 20%.
The intelligent controls used monitor the outside
temperature in conjunction with the desired room
temperature and adjust the boiler output to only
supply enough energy to achieve the desired internal
temperature. The colder it is outside, the more heat
is required inside.
Heating requirements for properties vary according to
insulation levels and occupier preference. Choosing
the correct curve will depend upon the insulation
property of the building. Better insulated buildings
will have a lower heating curve and require less heat
than poorly insulated buildings.
The Termo boiler software contains several heating
curves to cover most eventualities.
Termo boilers have factory set heating curves to
match the 2000 Insulation Requirement of the
Building Regulations. Full guidance to the selection
of an appropriate heating curve is given in the easy
to use installation and user manuals.
Note: Heating curve software is only installed in the
E version of the OSO Termo Electric boiler.
A number of off peak electricity schemes are available*.
Economy 7*:
Will require two meters installed in the home.
Economy 7 tariff is not recommended with Termo
boilers as power will not be available to the boiler
during peak periods.
Economy 10*:
Requires one meter
Off peak times are generally set for
Midnight to 05.00 (gmt) 5 hours
13.00 – 16.00 (gmt) – 3 hours
20.00 – 22.00 (gmt) – 2 hours
Times vary with electricity suppliers.
Economy 14*:
Requires one meter
Includes a long off peak time at night and other off
peak times available during the day. Times vary with
electricity suppliers.
By operating your Termo electric boiler with our
unique outside temperature compensator you can be
assured that your system will operate at its most
efficient and reduce / save energy – our electric
boilers are 100% efficient
The Termo electric boiler is versatile and can be
installed singly or as multiple units. Our boiler is easy
to site and can be fitted wherever there is an
electricity supply.
* You should make enquires with your electricity supplier
as to what tariff and duration are available in your area.
