Solar Panels and Tubes
An evacuated tube solar water heating system is a means of converting, by way of our roof mounted tubes or panels, radiated light from the sun into your domestic hot water. During the summer months it will give you almost all of your hot water. In the winter months it will supplement your conventional water heating system and significantly reduce your water heating bill.
What will it do?
It will give you FREE hot water! A Solar water heating system will provide approximately 60% of your annual hot water needs. It will replace increasingly expensive fossil fuels with free energy from the sun. It also helps to reduce global warming and reduces our carbon footprint.
Will my house be suitable?
Most homes in Ireland are. Evacuated tube solar collectors are generally mounted on an inclined roof. The panel should ideally face between south-east and south-west and not be subject to shadows. Any direction is suitable except north. Once installed correctly it will provide free hot water and add to the value of your house.
Will it work in winter?
It will work in Winter, but at a reduced rate. It will assist your domestic hot water production. In winter days are shorter and there are less sunlight hours available. Remember, it’s sunlight, not heat, that we convert. Solar water heating is used in much colder locations than Ireland.
Will it require maintenance?
An EZ Heat Solar system requires very little maintenance, just an occasional check of the pressure gauge and a quick visual inspection to check everything is ok. It is recommended for optimal performance to change the glycol in the system every 4-5 years.
Types Of Solar
Solar Thermal Panels or Solar Water Heaters come in two main types… Flat bed panels and evacuated tubes.
Flat Plate Collectors: Building-mounted flat plate collectors can be positioned both "in-roof" and on-roof due to their structure (heavy, rigid, robust box-like structure). The efficiencies of flat plate collectors make them very suitable for domestic installations or for installations where very high temperatures aren't required. They are often considered to be more optically appealing due to their flat surfaces, but this is a matter of personal choice.
Evacuated Tube Collectors: Building-mounted evacuated tube collectors can only be mounted on-roof due to their lightweight structure, which is most commonly individual tubes monted on a frame. On average, an evacuated tube collector will provide approximately 20% more yield per m2 of aperture area than flat plates, which means that less installed area is required for similar heat outputs. High efficiencies from low radiation and high temperatures (very useful where high temperatures are needed in process/industry)
