Solar Water Heaters

  By , ,









Solar water heaters can be a very useful way to saving money on your power bill. A water heater alone can easily cost a family of two $20-$40 dollars per month. Now think if you have a larger family what that could cost you throughout the year.

Heating your water by the sun is not a new concept. Back in the 1970’s there was a big push to conserve energy by heating your water with the sun. It however did not last very long. There are a few different types of solar water heaters out there. They can be as simple as laying a garden hose in the sun to a full enclosed system that uses a heat exchanger to transfer the heat from a liquid that does not freeze to the water.

The system that you decide on depends upon your location. If you live in a warm climate where it never or very rarely has freezing temperatures then you can go wth one of the more simple systems where the sun directly heats the water. The basics of the system include the solar water panel, some pipe and an old water heater. This is my favorite system because you can utilize your old water heater as a backup in case it is cloudy and there is not sufficient sun to heat the water. The old water heater also acts as a storage tank for the hot water and keeps it hot and ready for whenever you need it.

If you live in a climate that sees freezing and below freezing temperatures, you will need to go with a system that uses an antifreeze type of liquid just like your car so the water in the system does not freeze. You would also be wise to utilize your old water heater as a backup for when there are clouds or if the panels are covered in snow. You can also use the old water heater as a hot water storage tank using this method as well.








One of the best thing about solar water heaters is that they do not need electricity to run! This not only will save you money on your power bill but it will also allow you to take hot showers when there is no power! Imagine that there is a storm that comes through while you are at work and the power is out. You will still be able to take a hot shower.

Another advantage to having a solar water heater is that once you have it installed you are one step closer to being off the grid. In my opinion, this should be one of your first things to consider before going off the grid. Before you go and install $30,000 worth of electric solar panels on your house, put a solar water heater up there and start saving right away. It is also more efficient to heat your water with the sun than it is to power your old electric water heater by the electric solar panels you are thinking about putting up. This is because there are always losses with electricity. There will be losses due to heat, wire and electronics. This means that you are better off to heat your water with the sun first. This also means that you can save some money on the electric solar panels because the load that they will need to carry will not be as great. Electric water heaters can typically pull anywhere between 1500 and 4500 watts. This is 1500 to 4500 watts that you will not need to buy solar panels for.








Top 5 tips for using window units

  By ,





When summer approaches we all want to beat the heat and the way that some of us go about it is to use window A/C units. These unit do their job and they do it well but there are a few things that we can do to help them cool our homes more efficiently.

1. Check the rating.



Window units are typically rated by the number of BTU’s they can produce. However, most of us, do not have a clue what a BTU is and so the manufacturer’s of window units will typically tell you how many square feet the unit will cool. To find your square footage measure how big your room is and multiply the length times the width. You will want to make sure that you get a unit as close to your square footage as possible.

Most of the time it is better to go over just a little if you will be cooling an area with a kitchen or if you have high ceilings. You want to make sure the rating is close because if it is too small it will run constantly and not cool very efficiently therefore making your power bill higher. If it is too large the room could feel a bit moist since part of the job of the window unit is to dry the air as well.

2. Use fans.

That is right. Use fans to help mix the air in the room that you are using the window unit. This will help you be more comfortable instead of having one area that is hot and one that is cold. Another thing that the fans do as well is give the perception that it is cooler than it is. Moving air in the home can give us the perception that it is up to 3 degrees cooler than is. This means that we can set the thermostat to a higher temperature so that it does not run as much.




3. Use the thermostat.

This is very important but it also depends on the room that you are cooling. If you have one big window unit in the living room that you are using to cool the entire house then you want to find a temperature that is comfortable and set the thermostat and leave it. Now, if you are using a window unit in your bedroom you can set that thermostat higher when you are not in there so that it will not run all day to cool a room that you are not using.




4. Keep the filter clean.

Keeping the filter clean on your window unit can help save you energy when you are using it. When the filter is dirty the window unit has to work harder to move the air. This in turn means that it will take longer to cool the space that you are trying to cool. I know that when I am hot I do not like to wait any longer than I have to to be cool. This will also help your window unit last longer. Because the filter will be clean and the motor will not have to work as hard, the window unit will last longer.




5. Seal the air gaps.

This sometimes seems like a no brainer but I cannot tell you how many times I have had someone complain about their power bill only to find out that they are using a window unit. When I go inside to inspect I see air gaps everywhere. The fan on the window unit not only blows cold air but it sucks air in as well. This air has to come from somewhere and it is going to take the path of least resistance and if that means that it is going to come from around the door where you can see outside then so be it. Go to the hardware store and buy some insulation and some weatherstripping to keep out the drafts. Even tape can help on old drafty windows. Another problem area to address many times is the attic access.

These may be stairs or just an access hole. Many times the seal around these holes is not very good and lots of hot air can come from your attic. If you are not sure where to start with weathersripping and insulation, look at your windows and doors and if you can see daylight (I am not talking about through your glass window panes for you wise guys out there) you can bet that cold air is escaping and hot air is coming in. You can also crawl up in your attic and see if there is insulation. If there is no insulation, start here. You will see a dramatic improvement.

You will be suprised how much better your window unit works after you follow these tips!
