The OSO Termo is a 100% energy efficient,
intelligent modulating electric boiler, combining
proven commercial technology in a unique
design to bring the consumer one of the most
up to date and efficient electric boilers on the
market. Termo boilers can heat an indirect hot
water cylinder and a wet central heating
system, be it radiators, under floor or a mixture
of both with all the ease and controllability of
a gas or oil boiler.
Termo boilers are available with a choice of
2 heating control packages, Electronic (E) or
Electro-Mechanical (M).
E versions boilers are supplied with a fully
integrated outside temperature sensor. This
intelligent device consistently monitors the
outside temperature – the resulting information
being constantly relayed to the unique in-built
heating curve software. This exceptional
advantage offered by OSO can reduce energy
consumption by as much as 20%. (Further
heating curve information shown on page 9.)
E version boilers supplied for connection to hot
water cylinders are also supplied with a
cylinder temperature sensor that relays the
temperature information back to the boiler.
M versions boilers are supplied without the
heating curve software and do not have an
integrated outside temperature sensor.
Boiler operation is via standard boiler control
principles with the temperature and heating
controlled by room and cylinder thermostats.
Space heating only boilers are also available.
When ordering or specifying an OSO Termo
boiler the E or M version should be clearly
stated.
Underfloor heating (UFH) requires lower primary
flow temperatures than a conventional radiator
system. At OSO we have recognised this fact
and have our boilers in-built with an easily set
manually operated switch that ensures the
correct primary flow temperature range is
selected for the installed heating system.
