Solar Water Heating

Heating water is the second largest energy use in typical households
Solar water heaters can be a cost-effective way to generate hot water for your home here in Ireland.

One square metre of Solar Panels on your roof receives the equivalent of more than 100 litres of oil in free solar energy per year.
And as a matter of fact, this is more than in Paris.


Ok. But what if the sun is not shining?
No problem. A solar water heater not only converts direct sunlight but also indirect sunlight into heat, so it works even when the sky is overcast.
True,there will be less solar heat available during the winter, but a back-up
heater will boost the water temperature. The result is 100% comfort at all times, with plenty of hot water for a fraction of the cost.


Our panels have been fully tested and come with a 10 year Guarantee and are approved for the SEI Greeener Homes Scheme, which means that you can qualify for a grant of € 300 per m²(to max. 12 m² )


How Solar water Heating Systems work

Solar water heating systems include storage tanks and solar collectors.
There are two types of solar water heating systems: active, which have circulating pumps and controls,
and passive, which don't.

Solar water heating systems include two main items.
They are

1.Storage Tanks
2.Solar collectors


Types of Solar water Heating Systems

There are two types of solar water heating systems:

• Active, which have circulating pumps and controls,
• Passive, which don't.

Most solar water heaters require a well-insulated storage tank. Solar storage tanks have an additional outlet and inlet connected to and from the collector. In two-tank systems, the solar water heater preheats water before it enters the conventional water heater. In one-tank systems, the back-up heater is combined with the solar storage in one tank.

Solar Collectors

There are two main forms of solar collectors or panels on the market here in Ireland

Flat Plate collectors and Evacuated Tube collectors. 
See : Flat Plate or Evacuated Tubes

The main component of each is the absorber, which absorbs solar radiation and converts it into heat. 
In a plate collector, the absorber is in the form of a flat, black plate in a shallow metal container covered with one or more layers of transparent glass or plastic; either air or a liquid is circulated through the cavity of the container. 
Heat is directly transferred from the absorber to the circulating liquid (air, water)

The absorber in an Evacuated tube collector consists of a relatively narrow strip of copper with a selective black coating bonded to a single copper tube. The tube contains a special fluid which evaporates when heated. This vapour rises and transfers heat to the water circulating in the systems primary circuit.

Evacuated tubes are more efficient than flat plate collectors; consequently they take up less space. 
They are, however, more expensive that flat plate. Generally speaking, to produce a given amount of hot water,
whether using flat plate or evaporated tubes, the installation costs will be roughly the same.
