Riverdale Solar Installation Question: Does Solar Make Sense in a Cloudy Area?

Wednesday, March 7th, 2012

There is a longstanding myth that if you live in a cloudy area you can’t use solar panels because, after all, you cannot see the sun very often. However, the truth is a lot more complicated and thankfully for you it means that solar panels are in fact very useful in such areas.

First, the Science

Solar panels are designed to absorb ultraviolet (UV) rays which are what carry the light we see during the daytime. However that light is not the actual energy being absorbed by the panels. While we may see a ray of ‘sunlight’ as a single entity, it is actually very complex. The light itself may be partially blocked by the clouds, but the UV rays that your solar system needs to generate electricity still get through even on the darkest of days.

Of course, efficiency can drop on cloudy days, but for the most part, what is important is the number of hours of daylight, not the intensity of that daylight. Another thing to consider is that solar panels are actually more efficient when it is cold outside so cloudy environments that tend to be colder offset much of whatever energy loss they have due to lower daytime high temperatures.

Why the Difference Doesn’t Matter

The real issue in terms of solar generation is the number of hours of daylight averaged throughout the year. The longer the day, the more sunlight exposure your panels get and the more electricity they generate. Fortunately, most people have the option of staying attached to the power grid.

Unless you live in a rural area with no power grid nearby, you can simply remain attached and when the winter months roll around, pull electricity from the grid. Better yet, you can supply electricity to the grid during the summer months when you produce excess electricity (and yes, you will do that!) and have a credit on your account that allows you to get free electricity in return in the winter.

If you have any questions about whether or not a solar system will work with your Riverdale home, give Premier Indoor Comfort Systems a call!

Question from Norcross: What Is an Indoor Propane Heater?

Wednesday, January 4th, 2012

An indoor propane heater is an option if you’re looking to supplement your central heating system in a particular location. After all, when you turn on your heat, you’ll likely be heating your whole Norcross house. But if you’re only occupying a small area of the house at any given point in time, it may not be necessary to expend all of that energy to heat spaces that are completely unoccupied.

While electric space heaters are certainly an option in this situation, indoor propane space heaters are definitely worth a good long look. There are several different types of propane space heaters and most can easily be mounted on the wall of a room in your house to provide consistent warmth any time you need it. And because propane is generally much cheaper than electricity, you’ll be able to save a ton on your total home heating costs.

Indoor propane heaters are available in both vented and unvented varieties, and the type that’s best for you will depend on your specific heating needs and the dimensions of the space to be heated, among other factors. In general, it’s a good idea to have propane heaters installed by a professional to ensure that they’re safely in place and that they’re set up to provide the most efficient and effective heat possible.

The main difference between vented and unvented space heaters is that the unvented models simply circulate the air in the room and use its oxygen supply for combustion. Vented propane heaters, on the other hand, are able to take in air from outdoors for combustion and will also vent any gasses produced during combustion back outside.

When you do install a propane space heater in one or more areas of your house, it’s a good idea to have a carbon monoxide detector installed as well. That way you’ll have an early warning if something is going wrong with the heater. Although propane space heaters are quite safe, particularly when they’ve been professionally installed, you should still take every precaution to keep yourself and your family safe.

Components of a Geothermal Heating System: A Guide from Cumming

Monday, October 17th, 2011

A geothermal heating system in your Cumming’s home has three basic components and some add-on ones as well.

Its most distinguishing feature is the ground loops. The most common is the “closed” ground loop system, which is a series of pipes that are buried underground. These pipes contain a heat transfer fluid, comprised of antifreeze and water. This fluid absorbs heat from the ground and carries it to the home. This fluid also absorbs heat from the house and sends it into the ground to keep the home cool.

Examples of closed loop systems include the horizontal closed loop, which can be used in larger parcels of land (over an acre for example). The loops are placed typically placed horizontally 6-to-10 feet below the surface. A vertical closed loop design is recommended for smaller parcels of land and loops are often buried vertically approximately 20 feet underground. Other types of ground loop designs use well water to transfer heat in an open loop configuration, or have a closed loop submerged underwater in a pond or lake.

The next component is the heat pump, which draws the fluid from the ground loop. In a heat pump, heat energy is exchanged with the ground to heat or cool the home. In the heating mode, fluid warmed from underground flows through the heat pump. A fan blows across the pipe warmed by the fluid. Because the fluid is much warmer than the air inside the heat pump, heat energy is released into the cooler air. The cool air is warmed and distributed inside the home. The process is reversed for cooling. Cool fluid in the pipe absorbs heat from the warm air inside the home. Once pumped underground, the excess heat in the fluid is absorbed by the cooler earth.

The final component is the air handling or distribution system. Here, a fan in the heat pump’s furnace blows air over a fan coil and the heated cooled air is distributed through the home’s ductwork. Some distribution systems are hydronic, where hot water is circulated through radiators or radiant floor heat tubing. This water absorbs heat from the heat pump and then distributed throughout the home.

In some homes, both a forced air and hydronic system, often referred to as a “hybrid system” work together.

Optional components include a heat pump “desuperheater,” which is used to help with domestic hot water heating. In warm weather, the desuperheater recovers some of the heat – that would otherwise be sent to the ground loop – to help produce hot water. In cold weather, some of the heat pump capacity may be diverted from space heating for the same purpose. Desuperheaters save approximately 25% on domestic water heating costs.

Another component is an auxiliary electric heater, which is built into the geothermal heat pump This auxiliary electric heat is installed to allow heating and cooling technicians to size – or resize – a home’s geothermal heat pump system to assist the system during the few coldest days of the year. Auxiliary electric heat is also an emergency backup heat source if there are any operational issues with the geothermal heat pump system.

How Do Solar Cells Work? A Question From Norcross

Monday, September 26th, 2011

Rising energy costs and concerns over depleted resources have many people seeking out alternative energy sources for their Norcross homes. One popular solution is solar cells, which harness clean energy from the radiation of the sun to use as electricity. This technology is not terribly new, of course, having been used in calculators for years. A house is rather different from a calculator, though, so the prospect of using solar cells as a source of electricity lends itself to some questions, especially “how does it work?”

How it Works

As you might imagine, there is some complex science behind how cells really work. Rather than get down to the nitty gritty physics of it all, a brief overview should do. Essentially, the radiation from the sun is a tremendous energy source, emitting up to 1000 watts of energy per square meter of Earth in a single day.

The materials in solar cells make them photovoltaic (PV), meaning they are able to convert light to energy. When light strikes the PV cell, its energy is passed along to a semiconductor, thereby generating a current. There’s a good deal more complexity involved in the process but essentially that’s it.

Making It Work for You

There are a number of issues to consider and obstacles to overcome in installing solar cells that work properly, such as:

  • Angle and Orientation – Ideally PV cells should be directed south, at an angle that is as close to the latitude of their location as possible. All sources of shade and other obstructions must be removed for the sake of efficiency.
  • Storage and Backup – The sun doesn’t shine all the time, so you will need a backup system in place. Some options include connecting your home to the power grid, using deep cycle batteries to store energy for use later, or installing a backup generator.
  • Current Inversion – The current produced by the photovoltaic process is DC, so in order to be used like “regular” electricity from a wall socket, it needs to be converted to AC. This means installing an inverter as part of the system. Some PV cells come with invertors built in.

Installing SunSource® Home Energy System can be a clean and budget-friendly idea, but it can also be somewhat complicated. Proper materials and installation are vital to proper functioning, so consult with a professional if you are in doubt.

Is Your Home More Valuable with Energy Efficient Appliances? A Question From Fairburn

Friday, September 16th, 2011

It’s impressive the things people do to improve the value of their Fairburn home. We’re talking about crown molding, new floors, new siding, upgrades to the landscaping and much more. The cost of upgrading these things can grow out of hand quickly and if the boost to your home’s value isn’t equally exponential, it’s hard to justify the expense.

So, it’s always nice to find a simple upgrade that can be performed for a few hundred dollars that will save you money immediately and improve the value of your home in the future. Your appliances are one such upgrade.

The Value of Energy Efficiency

An energy efficient washing machine can save upwards of $150 per year on water costs. An energy efficient toilet cuts consumption by as much as 150%. Low flow shower heads cut water costs by one third to one half and your heating and air conditioning systems can be improved by 10-35% depending on the upgrades available to you.

When you add up all those savings, the result is a tremendous amount of money that can be saved each year on everything from your water bill to your cooling needs. Imagine what happens when someone looks to buy your home. They see that there are all new appliances with energy efficient ratings that will save them money.

It’s not just lower bills; it’s a decrease in upfront investment. On the surface, it’s unlikely that your energy efficient appliances will directly increase the value of your home, but they can increase the likelihood of someone paying what you’re asking for the home. They add value to the livability of the home, if not the property itself and in today’s housing market, that’s a major plus.

Best Upgrades

The best upgrades to your home’s appliances are the ones that save money without additional work. Major upgrades to your heating and cooling are good if you need an upgrade anyway or you plan on staying in your home for a few years.

Basic HVAC Terminology: Some Tips From Smyrna

Monday, September 5th, 2011

Ever try to look up basic information about your heating and air conditioning systems in Smyrna? There are dozens of terms that might as well be Greek for all you know – a mishmash of words and phrases talking about energy efficiency and air flow ratios. To make your next upgrade a little easier and give you a baseline with which to work, here are a few of the most common HVAC terms you’ll hear in the industry:

  • AFUE – Annual Fuel Utilization Efficiency – This is a simple measurement of how much fuel a furnace converts into actual heat in your home. So, if a furnace converts 92% of the fuel it consumes into heat, it has an AFUE rating of 92.
  • Watts – A single watt is a measurement of electricity. Commonly, your electricity use is assured in kilowatts or kilowatt hours (kWh).
  • BTU – British Thermal Unit – A BTU is a common measurement of how much energy is produced or consumed by an appliance. When referring to an air conditioner, one “ton” refers to 12,000 BTUs.
  • SEER/EER – Seasonal Energy Efficiency Ratio refers to how many BTUs can be produced with a single Watt of electricity per hour. So, an air conditioner with an SEER of 14 can produce 14 BTUs of cooling per watt consumed each hour.
  • HSPF – Heating Seasonal Performance Factor – Refers to the efficiency of the heating elements in your heat pump.
  • COP – Coefficient of Performance – A measurement of how effective your heat pump is at heating a space compared to standard electrical resistance heat. The lower the temperature gets outside, the lower the COP will be. Equipment is usually measured for COP at 47 and 17 degrees to give an idea of seasonal performance of a new heat pump.
  • Refrigerant – Refrigerant is any gas that is used to draw heat from the air in a particular environment through an air conditioner or heat pump. It has a much lower boiling point than water, allowing it to cool despite the temperature outside. Currently, most equipment uses R-22 refrigerant while the new standard will be R-410A (Puron), legally required in all cooling units by 2020.
  • CFM – Cubic Feet per Minute – Used to measure the volume of air passed through an air handler by an air conditioner or furnace.

There are a number of complicated details to keep track of when choosing a new air conditioner or furnace. To ensure you get the very best out of your system, read up on these details in advance – you’ll feel a heck of a lot smarter when you call.

The Preventative Maintenance That Will Save You the Most in Hampton

Wednesday, August 3rd, 2011

Having a high performance, energy efficient HVAC system will save you a good deal of money in terms of your monthly heating and cooling bills, whether you live in Hampton or Lawrenceville. But that efficiency will not last unless you also take the necessary steps to keep your equipment in good working order. While regular maintenance visits from a professional HVAC technician are an important part of this, there are also several things you can do on your own to keep your equipment running at peak efficiency.

  1. Keep it Clear – The first thing you should do is to make sure that there is plenty of space cleared around your outdoor unit. Whether it is the condenser and compressor for your air conditioning system or part of your heat pump, that outdoor equipment needs to have plenty of space to vent hot air. Also, the space will mean that debris is less likely to develop inside the unit.
  2. Clean the Condensing Coil – While your technician will do this when they make their annual visit, it is best to clean your coil more than just once a year. Just make sure that the power is turned off to your unit before you begin. This will help the unit cool air more efficiently and can prevent a whole host of other problems from developing.
  3. Check on the Blower – If your blower is not working right or the blade is clogged, your HVAC unit will not work properly. Make sure your blower fan is free of all debris and that is turns freely once you have cleaned it. If you are still having a problem with it, you may have to call a technician for repairs. Cleaning the blower out on a regular basis, however, should keep this from becoming a problem you need a professional for.
  4. Air Filters – You should also make sure you change your air filters regularly. This can help to keep your indoor air clean and healthy and it will also enable your HVAC system to run more efficiently.
  5. Clean it Out – Clean out any debris that you can reach from any part of your system. Just make sure any time you work inside your HVAC system that you have all of the power turned off. Anything from leaves to dust can get in there and cause a problem if it is allowed to build up over time. As long as you are on top of things and keep to a regular schedule of maintenance, none of this should take you very long.

Home Inspection 101

Wednesday, July 20th, 2011

When you are buying a house, you want to make sure you know exactly what you are getting. One of the most important things you should do before you agree on a deal is to hire a professional home inspector to come out and take a look. However, hiring these inspectors is expensive and you do not want to waste time and money on a house that is not worth it.

For that reason, it can be very helpful if you can take a look at a place on your own first to see if it is even worth making an offer on. Of course, you cannot complete the type of inspection that a professional would be able to do, but you can take a look for some important and easy to spot problems that will give you a good idea whether or not it is even worth taking the process on this house any further.

For instance, you should start by taking a look at the house from a good distance away. Make sure the house actually looks like it is standing upright and that it is even. Sometimes from a distance you can see that a house is actually leaning to one side when that is not obvious up close.

Also, this will give you a chance to check out the lay of the land around the house. Remember, you want water to flow naturally away from your house so that it does not get into the basement and cause a problem on a regular basis. That means that you want the ground to slope away from the house rather than be flat or slope towards it.

Check out all of the plumbing and be sure to run water, flush toilets and thoroughly inspect all bathrooms and the kitchen. You want to see high quality fixtures and good water pressure. Also, check to see how long you have to wait to get hot water at various locations throughout the house.

Be sure to find out what type of heating system the house has in place as well and how old it is. Even a system that works well will need to be replaced soon if it is more than 10 years old. While this may not necessarily stop you from purchasing the house, the cost of replacing that system can certainly impact the amount you are willing to offer.

Save Money When Using Appliances and Home Electronics

Wednesday, July 13th, 2011

As you are looking around your home for ways to save money on electricity, it is only natural to linger on the big things like your heating and air conditioning systems. However, there is also a lot to be saved in other areas if you know where to look and how to go about cutting back. Both the type of appliances that you buy and the way that you use them will directly impact your total electric bill every month, so it is certainly worth paying attention to what you are doing and what you could do better.

For one thing, it is almost always worth it to go with an Energy Star certified appliance whenever possible. It does not matter if it is a coffee maker or a washing machine. Every little bit helps and so you will be setting yourself up for much lower electric bill over time when you figure total energy usage into all of your purchases.

Using power strips is also a great way to make saving on electricity easy. No matter what you do, many appliances will draw a small amount of power even when they are switched off. So as long as things like your laptop, TV and toaster are plugged in, they are draining energy whether you are using them or not.

Of course, you could just go around and unplug everything you are not using, but that can get pretty tedious. Plugging these types of appliances and home electronics into a power strip makes it easy to just cut their power supply completely when you do not need them. And switching them back on again is just as easy. You do not even have to go crawling around on the floor looking for the plug.

There are certainly many items that you cannot or do not want to unplug or completely cut the power to at any time. For appliances and electronics that fall into that category, simply make sure you turn them off completely when they are not in use. Many home electronics will automatically switch to a standby mode rather than shutting down completely and it is easy to forget they are still on. However, you will save a lot if you make sure to shut them down completely when they are not in use.
