SOLARcomfort systems are highly efficient and provide cost savings on
the energy used for heating hot water wherever they are used in the UK.
However, the savings made will depend on local climate, installation
characteristics and the household’s domestic hot water requirements.
It is important that the SOLARcomfort system is correctly sized for the
local climate condition and the householders requirements.
After installation of the SOLARcomfort system, changes to the
householders use of hot water will be beneficial. Simple changes such as
bathingintheeveninginsteadof the morningandputting automatic washing
machines on when free hot water is available by solar energy.
In addition, the timing of the dwelling’s boiler controls must be modified to
ensure the‘hot water ON’time is set so that the water temperature in the
cylinder is at a minimum by the start of the ‘solar day’.
The solar collectors are heated by the sun’s rays. The heat generated is
storedin a hotwaterstorage cylindere.g.AristonPrimotwin coilstainless
steelcylinder. Thesystemcontroller continuallycompares the temperature
ofthe water withinthe cylinderwith the temperatureof the solarcollectors.
Wheneverthe solarcollectors arehotter thanthe water withinthe cylinder,
thecontroller switchesonthe system’s circulatingpump. Thetemperature
differential between the collectors and the cylinder is set via the AST 100
Solar Controller. The heat transfer fluid within the solar system is then
circulatedthroughthe collectorsandthecylinder’sheat exchanger,heating
the cylinder in just the same way as a central heating boiler.
The cylinder typically has two coils (heat exchangers), the lower coil is
heated by the solar system, therefore solar is the primary heat source.
Theupper cylinder isheated by anauxiliary heat source,typically acentral
heating boiler, which is used to heat water when there is insufficient heat
generated by the solar system. The Ariston PrimoTwin cylinder also has
twoimmersion heatersmaking it suitableforelectric onlyheating systems.
The SOLARcomfort system is a forced circulation sealed system and
therefore requires an expansion vessel and a pressure relief valve (PRV),
both supplied with SOLARcomfort.
Theairseparatorwithanintegralmanualairventtogetherwithan automatic
air vent positioned at the highest point on the system ensures that the
sealed system remains free of air.

2. SAFETY WARNING - RISKTO LIFE
Correct procedures must be followed when lifting the collectors.
To satisfyHealth and Safety requirements relatingto the construction
industry, the use of a crane or other lifting device may be required.
Take appropriate precautions to prevent accidents and falls when
working on roofs.
Ensure correct personal protective clothing and safety equipment
are used when working on roofs.
Ensure that collectors lifted onto the roof or scaffold are always
secured to prevent them slipping and falling off the roof. Serious
injury or death may result from collectors falling.
WARNING
The collectors must be correctly secured to the roof. The roof must
be of adequate structure to support the collectors.
WARNING
During operation and commissioning the temperature of the heat
transferfluidwithin the system and collectorscanreachtemperatures
high enough to present a risk of scalding. Never loosen fittings or
open vents when the system is hot.
WARNING
TYFOCOR LS HeatTransfer Fluid.
Although non-toxic it should not be swallowed.
Refer to label on its container for storage and safety information.
A detailed technical specification is available from Ariston on request.
Caution
SOLARcomfort should be installed and commissioned by approved
contractors. Failure to do so may invalidate the warranty.
Caution - Risk of damage to collectors
IMPORTANT! Always keep the glass side of the collectors fully
covered until the system is filled and ready for operation.
Always transport the collectors in an upright position. Never position the
collectors with the glass side facing down.
Leave collectors in their packaging until the time of installation. Do not
allow the bottom side of the collectors to be damaged by sharp objects.
Never leave the collectors with the glass side down when they could be
exposed to theweather,as rainwatercould infiltrate thecollectorandcause
condensation within the collector.
Note:
Optional lifting handles are available
from Ariston (code 3107023).
