The Renewable Heating Specialists

Solar Water Heating can help you to reduce your water-heating bills and protect the environment!

Solar energy can be used in two different ways:

- Solar Thermal systems

These use the sun’s energy to produce hot water usually for baths, showers and basins.  Sometimes they can be used to heat underfloor heating, but not generally radiators.

- Photovoltaic panels

These use the sun’s energy to generate electricity which is usually sold to the National Grid.

At Llani Solar we supply and install Solar Thermal systems - to produce hot water for a wide range of domestic and commercial uses.

Households on average spend between 27% and 35% of their total energy cost on heating water. Solar panels can significantly reduce bills (producing around 60% of a households annual hot water needs) and at the same time substantially reduce carbon dioxide emissions.

For more information about how Solar Thermal systems work, and a very simple self-assessment chart to find out if solar water heating is right for you, please download our Solar Fact Sheet.

We value our independence and only install the best solar collectors on the market in the UK!

As independent installers we install only the solar collectors we consider to be the best.   We will install either flat-plate collectors or evacuated tube collectors according to the circumstances of the installation. For a discussion of the various merits of each type of collector, please download our Solar Fact Sheet.

For new build projects, or houses being re-roofed we recommend VELUX roof-integrated solar collectors.  These are fitted when the roof is felted and battened, prior to slating or tiling. This means the collectors sit flush to the roof line. Where customers are also installing VELUX roof lights we can fit VELUX solar collectors to match. 

For existing properties where solar is being retrofitted to an existing roof we recommend are Gasokol flat-plate collectors and Thermomax evacuated tube collectors.  The collectors are installed on a railing attached to the roof.  A small number of slates/tiles are removed from the roof, for the pipe work to be fed through, and the hole covered with a lead flashing. 

We are also happy to install a range of other high quality solar collectors including Ritter.  If you want a particular solar collector that you have your heart set on, why not give us a ring and we will let you know if we are happy to install it.

We are fully accredited under the government’s Microgeneration Accreditation Scheme, as are all the solar collectors we install. This means if we install your solar water heating system then you are eligible for the government's Low Carbon Buildings Programme and other grants. 

Want to know what the solar panels will look like?  Take a look:

The following information will give you a good idea of how the solar collectors might look on your roof:

1. VELUX solar hot water system (SO6, SO8, MO8, U12)

New in the UK!

Llani Solar is proud to announce that it is one of the first companies in the UK to install VELUX solar collectors.  Although you may be aware of the Velux range of roof window, you may not know that they also do a range of solar collectors.  When it is installed the solar collector integrates into the roof just like a VELUX roof window.

VELUX has more than 50 years' experience of roof integration. So they have been able to develop solar collectors that can be fitted easily, quickly and efficiently as they integrate into a roof. The result is a flush, sleek finish, with the collector looking like a part of the building design, not an 'add-on'.

Available in four different sizes and using standard flashings it can be combined with existing to new VELUX roof windows to ensure a visually attractive roof design.

2. Gasokol tecSol and topSol solar collectors

Gasokol GmbH is one of the leading solar energy companies in Austria and produces solar collectors and collector accessories.  

Gasokol technology is based on over 20 years of experience in the solar collector field, which uses the finest solar collectors on the market, combined with extremely efficient heat transfer systems and state of the art controllers ensuring the very highest levels of efficiency.

Gasokol solar collectors are manufacturered to the highest levels of technical excellence using leading edge technology. The collectors are guaranteed for 10 years and require little or no maintenance.

High quality raw materials and proven quality assurance systems ensure products of the highest quality. Intelligent product design reduces the expenditure for packaging. Gasokol only uses recyclable timber and cardboard packaging.

The Gasokol tecSol collector is designed to be fitted onto an existing roof or to be free-standing; installed on a specially designed stainless steel A-frame mounting.

3. Thermomax

Thermomax evacuated tube collectors are manufactured by Kingspan Renewables Ltd in Wales and at the Kingspan Renewables headquarters in Northern Ireland. 

Solar thermal technology transforms direct and diffuse solar radiation into useful heat using a solar collector. Each solar collector consists of a highly insulated manifold and a row of solar tubes. The vacuum inside each tube provides perfect insulation and therefore protects the system from outside influences such as cold and windy weather or high humidity.The Thermomax brand is the original and still the best vacuum tube collector in the world. 

The unique ‘plug and play’ design of Thermomax solar collectors makes installation quick and easy. There is no need for heavy lifting equipment, as tubes can be carried onto the roof individually. The collector is fixed to the roof by easy-fit roof brackets, which are simply fixed to the rafter.

4. Ritter CPC6 INOX solar collectors

Ritter Solar is a manufacturer of highly efficient evacuated tube collectors with CPC reflectors. 

The Ritter Solar evacuated tube collector consists of 3 main components:

Evacuated tubes - the tubes are composed of two concentric glass tubes.

CPC mirror - in order to increase the efficiency of the evacuated tubes, a highly reflecting, weather-proof CPC mirror is placed behind the evacuated tubes.

Collecting box with heat transfer unit - in each evacuated tube there is a U pipe with direct flow-through that is connected to the collecting or distribution pipes.

Do you have an odd-shaped roof or restricted space?

Flat plate collectors can be installed horizontally, enabling us to install them in narrow or odd shaped roofs.

 

 

 

 

 

 

 

 

 

Evacuated tube collectors are smaller and more compact than flat plate collectors, so can be fitted into smaller spaces on roofs.

 

 

 

 

 

What if it's not possible to fit solar collectors on your roof at all?

The ideal location for solar collectors is on a south-facing roof. Where this is not available, for example the roof faces East/West, or it is a Listed Building or in a Conservation Area where permission would be refused, there are several alternative options:

 

Solar collectors installed on a flat roof of the garage. Collectors installed horizontally, rather than vertically, to reduce the profile to the wind.

 

 

 

Solar collectors mounted on an A-frame on the south-facing gable wall of a house.

 

 

  

 

Solar collectors mounted on an A-frame in a sunny location in the garden.
