Introduction to Solar Thermal from Timoleon TN21 Solar Thermal Timóleon from 2014 Solar Thermal

Timóleon Solar Thermal Systems are able to collect the sun’s energy so that it can be used for both heating and hot water.

All Timóleon hot water systems enable the homeowner to benefit from RHI payments as well as making significant savings on their energy costs.

Energy from the sun

Solar thermal is very effective as an alternative energy source. In the UK we receive up to 1200kWh (units) of solar energy per square metre of land each year with Contents energy available even on a cloudy day. Compare this to the annual heating and hot water consumption of a 3 bed house of about 10,000kWh and it is clear that solar can make a significant saving to the energy costs if collected and efficiently used. Introduction to Solar Thermal pages 2-3 The energy collected from solar thermal can be very useful however during the spring, autumn and winter this is often at a low temperature. For this to be useful the underfloor heating needs to run at low water temperatures and have a control Hot water system that is able to make intuitive decisions based on how cold it is and the pages 4-7 temperature of the stored water. This delays the need to use a or until there is no useful energy available from the solar panels. Timóleon’s SunCylinder does just that, enabling up to 40% of the total house heating load Heating / Hot Water to come from . pages 8-11 Timóleon also supplies conventional Solar Thermal systems for domestic hot water. These systems can supply up to 60% of the hot water demand (15% of the total Solar Thermal Panels house load). pages 12 -14

The Incentive (RHI)

From Spring 2014 solar thermal installations providing DHW only can benefit from RHI payments. For applicable prop- erties the proposed tariff will be 19.2p/kWh which for an average 3 bedroom property is £600 per year. This is available for 7 years so the total payment would be over £4,000. Add this to the saving on your fuel bills and using solar thermal makes clear economic sense.

For more information on the RHI please go to our website www.timoleon.co.uk or call us on 01392 36 36 05, we’ll be happy to help.

Is Solar Thermal suitable for your projects?

Solar thermal has an application in most projects. There has to be sufficient space on the roof and this must not be north facing. Panels should be installed at an angle between 300 and 450. Depending on the orientation of the panels and the application (space heating has a higher demand) more panels may be needed to collect enough solar energy. The number of panels needed for each application is explained in this guide. Planning permission

Planning permission is not needed for most solar thermal installations. There are exceptions, these being listed buildings, areas of outstanding natural beauty and conservation areas. It may still be possible to install solar collectors but planning permission will need to be sought.

3 Solar Thermal Soler Thermal for Hot Water Timóleon has a range of packs for those projects that require a solar thermal system just for domestic hot water. Each pack is configured for the number of occupants within a building with the solar collector size based on standard orientation and location. If there any special requirements Timóleon can put together a bespoke package. Typically a combined collector size is about 3 to 5m2.

Solar Thermal for domestic hot water (DHW) purposes is very well suited to high occupancy levels where there is a large demand for DHW and conversely less appropriate where there is a low demand such as commercial projects.

The Timóleon solar collectors absorb the incident solar energy and convert it to useful heat. Solar fluid is circulated around the panels absorbing the heat. The fluid is then circulated through a coil situated in the hot water cylinder. Here the heat energy is transferred to the water in the cylinder. This water is used directly for the home’s hot water needs.
