New Construction: Air Sealing for Energy Savings
Larry Janesky from Dr. Energy Saver walk us through a new construction to show us how to air seal the gaps and openings commonly left around windows and doors. Air sealing these gaps will prevent air leakages, which are usually responsible for a lot of energy waste. The energy loss through air leakages in an average U.S. home is the equivalent to leaving a window open all winter long, 24/7.

The Best Winter Energy Saving Tip Ever
The agency "projects average household heating expenditures for natural gas, propane, and heating oil will increase by 3 percent, 7 percent, and 8 percent, respectively, this winter (October 1 to March 31) compared with last winter,… Average expenditures for households that heat with oil are forecast to be higher than in any previous winter."
If there was ever a good time to start getting serious about greening up your home and save energy, the time is now. Investing in the right energy saving improvements, will help you save money and make your home more comfortable this winter and for many years to come.
While some upgrades like new HVAC systems and Solas Panels can be very expensive, some of the most cost effective improvements, the ones that will bring the most savings per dollar invested, sometimes are very affordable too. Air sealing and insulation for example, can help you lower your heating bills by up to 40%!
Combine that with several Federal and Local Energy Efficiency Incentive Programs, that will help you pay for the cost of the improvements and you have a win-win situation.
But you need to start acting now, before winter strikes and the heating bills begin to take a bite out of the money that could be better spent in energy saving improvements.

The Pros and Cons of Tankless Water Heaters
Dr. Energy Saver Delaware and Extreme Makeover Home Edition Retrofit Mardela Springs Home
80 years ago the foundation of the Johnson-Goslee family home was laid for generations to enjoy. It was nearing its last days just before being chosen by Extreme Makeover: Home Edition and the Fusion Companies as their next redesign.
Thousands of volunteers and donations aided the week-long project to repair the settling foundation, structural problems, plumbing, and other difficulties. Dr. Energy Saver Delaware and DryZone, LLC, local Delmarva contractors, provided all the materials and manpower to install more than 3,000 square/feet of the CleanSpace® system complete with Drainage Matting, the SaniDry® CX, and a condensate pump. All of which was completed in less than three hours only with the help from the contractor’s employees who volunteered their time to complete this gift to the Johnson-Goslee family.
The Johnson-Goslee family endured their home’s shortcomings proudly and unashamedly. Even after 16-year-old Whyzir lost his hand while helping his grandfather repair the home last Christmas Eve.
It will take more than losing a hand to deter this teen from helping his family and bettering his community, “It's not what I wanted to hear, but I know it was in God's plan for me,” Whyzir said.
For a young man who understands and contributes to giving and serving the community, it became time he and his family received a gift and enjoy a safer and healthier home.
Wyzhir lives with his mother, sister and Aunt.

Attic Insulation: Not Just for Colder Climates.
|
There is a common misconception concerning attic insulation across the US. People tend to think that beefing up attic insulation only makes sense in colder climates. Yet, the vast majority of homes in the US, even those in colder areas of the country, have poor attic insulation. Usually less than half of the Department of Energy's recommended R-Value for attic insulation in any given area. In South Carolina, mild winters and hot summers lead people to think that they hardly need any at all, often forfeiting that important step when investing in green home improvements.
The role of insulation is to prevent thermal losses by slowing down conductive heat transfers. The attic is the one area of the house where the most drastic temperature changes occur year round. During the summer, the sun heat is transferred from the roof to the attic, resulting in scorching temperatures. A heated attic makes your whole house hot, and your HVAC will have to work much harder to keep you comfortable. The process is reversed in the cold days of winter. Because temperatures migrate from high to low, the heat in the living area will be transferred to an insulated attic at a greater rate, through the ceiling, and put an extra burden on your heating system. The energy penalties can be even more significant if you have ducts or your HVAC unit running in the attic. In addition, improper air sealing of the attic will also increase energy losses through leakage. The heated air in the house will rise, escape through the openings in the attic, causing unconditioned air from the outside to be consistently sucked in from the lower levels of the building, and making your HVAC work harder to keep up with heating and cooling all that new supply of air. In building science, that phenomenon is know as the "stack effect". Poor attic insulation and air sealing can also be responsible for moisture buildup in the attic, mold, dry rot and ice damming in the roof. And the pretty icicles we see dangling down the roofs when it snows are a tell tale sign of an energy wasting attic. If you are serious about making your Columbia, SC home more comfortable and saving money in your energy bills, give Dr. Energy Saver Columbia a call. Schedule a free attic insulation estimate, or ask for a full home energy audit. Let them show you how you create a green, healthy and energy efficient home. |
Tankless Water Heater: Is it Right for You?
Tankless or Demand Water Heaters are the "new" thing in terms of water heating systems, for a number of reasons.
When compared to conventional storage tank water heaters, they are much more energy efficient, more compact and provide, an endless supply of hot water, shower after shower, load after load of dishes, because they heat water as it is used.
They aren't however, a "new" thing. Tankless water heaters have been used successfully overseas for many years. The technology was being overlooked in the U.S. in times where energy prices were lower and more stable than they are now, the demand wasn't as high, and the resources weren't so scarce.
Now that we are faced with dwindling fossil fuel supplies and able to measure the impact that our energy consumption has in the environment, the tankless water heater re-emerges as a viable way to get much needed hot water and waste less energy.
If you need to replace your old water heater, and want to know if a tankless water heater is the right choice for you, here are some facts that you should consider.
Energy Efficiency
In terms of energy consumption, a tankless water heater performs much better than a storage tank unit. With a tankless model you can cut your water heating bill by as much as 45%.
In a storage tank, there is what we call a "standby heat loss". The water in the tank cools down and needs to be reheated several times a day, in order for you to have hot water whenever you need. That happens several times a day, 24/7, 365 days a year, regardless of whether you are awake or asleep, at home or away.
A tankless will only heat water when it is needed.
Upfront Cost
While tankless water heaters are becoming more affordable, the price for a tankless unit is still a bit higher than the price of a storage tank unit. Installation can also add up if you are replacing an old tank by a tankless, or an electric for natural gas model, as the work may involve making some adaptations.
The good news is that until the end of December 2011, natural gas powered, ENERGY STAR qualified tankless units qualify for a federal tax credit.
Tankless units may also qualify for many other incentives available at a local level in many states, including South Carolina
Tankless units also last much longer than storage units. Expected life of tankless water heaters is 20 years, compared to 10 to 15 years for tank-type water heaters.
Installation
As we said before, if you are replacing an old tank unit by a tankless, there might be the need to adapt some of the existing pipes. On the bright side, tankless units are compact and much smaller than bulky storage tanks, and can fit is small spaces. They are also less susceptible to corrosion than tank units and not as likely to leak and flood the area.
Performance
A tankless water heater significantly reduces energy consumption. Natural gas powered units are also more energy efficient than electricity powered models.
Best results, not only in term of savings but overall performance, are obtained when the model is made to fit the household size, schedules, needs and profile.
Some of the common complaints associated with the use of tankless are usually related to the type and capacity of the system being used.
One of the common complaints is that tankless units can't handle multiple simultaneous uses, such as showering and running the dishwasher at the same time.
Truth is that some models have the ability to modulate capacity to match usage, and operate at the most efficient setting according to how much water is needed. Some models lack that ability.
For homes with many bathrooms, larger families and busy schedules, sometimes it makes sense to install two or more smaller units, to handle different needs.
In addition, let's face it, can you really wash your dishes and shower at the same time with a tank-type model, without quickly running out of hot water?
Another common complaint regarding tankless water heaters is the so called "cold water sandwich". Cold water standing along the pipes than may cause a sudden burst to come out a few seconds after you turn on the hot water. That can be unpleasant if you are in the the shower, but it can be solved if you wait a few seconds before getting in. It usually takes less time than it would normally take for hot water to come out of a tank-type unit.
