Three Things You Will Want To Know About Solar Energy For Heating And Hot Water

If you want affordable solar power, a water heater powered by the sun is a great option. There are a couple of different types to choose from such as a panel collector or an evacuated tube system. The evacuated tube solar water heaters give you many benefits and can be more reliable that some of the other options. This is why many homes that rely on solar power have the evacuated tubes installed. There are still many options when it comes to installing these systems, and here are some things that you may want to know before having one installed on your home:

1. The Amount Of Tubes In The Panels To Heat Water

Evacuated tube panels contain pipes that are enclosed in tubes. The evacuated tubes add to the efficiency of the collector, insulating it and allowing it to work in even the coldest climates. The pipes heat as sunlight passes through the gas and then the convection of the heat makes the water rise to fill the tank or be distributed to a storage tank. The more tubes your system has, the more capacity for heating water your will have.

2. Roof Mounted Tanks Or Thermal Storage Attached To Conventional Systems

There are two choices when it comes to tanks for a solar water heater. You can have a tank that is mounted on your roof with the panel to store the water, or you can have a storage tank located near your conventional water heater or boiler. If you are going to have a larger system installed with more than one panel, you may want to consider a thermal storage tank, which will be a more efficient solution. Storage tanks are also more aesthetically pleasing because you will not have a big water tank on the roof of your home.

3. Closed Loop And Open Loop Systems In Different Climates

There are also two different types of solar water heater systems; they can be a closed loop system or an open loop system. If you live in a colder climate, a closed loop system will have antifreeze in it and act as a heat exchanger for your system. The closed loop separates that solar water heater from the plumbing in your home with potable water. If you live in a warmer climate, the open loop system can be used and water from your plumbing will run directly from the solar heater to the storage tank or water heater.  

These are some of the things that you may want to know before having one of these types of water heaters installed on your home. If you are ready to add a solar water heater to your home, contact a professional plumbing contractor like C J Plumbing & Heating and ask them about evacuated tube water heaters.
