For maximising the use of the renewable 'green' energy, the system should be managed
and controlled so that unnecessary fi ring of the boiler is kept to a minimum. This can be
achieved by a combination of householder use of the system and controls, for example;
Use the store to provide shower or a bath to utilise the heat gained by the system from
the previous day's solar energy input. Alternatively showering or bathing in the evening
will utilise the energy that has been stored during the day from the solar system.
• As with any system, hot water and space heating should be programmed according
to house holder requirements. However it is always good to remember that to gain
maximum advantage from the solar panels, the store should be as cool as possible,
prior to expected periods of high solar gain. To achieve this in spring, summer and
autumn, the hot water channel of the boiler should be programmed to come on 30
minutes before the hot water is required in the morning and then programmed off
before volumes of water are drawn off the system. This way the store is depleted
of heat allowing maximum transfer from the solar system during the day.
• However further supplementary time periods for the boiler will be required in
winter when not much solar energy is available.
• Uncontrolled boiler operation can also be reduced by fi tting and wiring a pipe
thermostat on the solar return pipe close to the Torrent SOL.
As part of setup and commissioning, it is important that this boiler hold-off pipe
thermostat be adjusted to fi nd the best setting for each individual installation.
Failure to do so will give under performance of either the boiler or the solar heating
system.
Please note, the Torrent Greenheat should not be held at temperatures above 85˚C
for prolonged periods.
A solid fuel boiler can also be connected to the Torrent GreenHeat SOL, please refer
to page 20 for further information.
