Radiant heating systems do not have a lot of moving parts, so it they aren’t as prone to breakdown as other systems can be. However, this doesn’t mean that you may not have to repair your radiant heating system. The type of radiant heating system you have – hydronic or electric – helps determine what kind of radiant heat repairs you may need. As with any kind of heating system, it’s always best to hire trained experts for repair. If you are experiencing problems with your radiant system in Brookline, MA, call for an FB Electrical Services expert today!

Electrical Radiant Repairs

Electrical radiant systems use electric cable to heat. The cable can be set into cement, installed to subflooring or be part of an electrically-conductive plastic mat that is installed to subflooring. A couple of common problems that can develop with electric radiant heating are:

As a Dallas Electrician with over 27 years of experience, ElectricMan Inc. has seen many of the dangers of DIY Electrical first hand, and has often been called in to make repairs after a DIY home improvement project has gone wrong, or the home owner realized that they were in over their head. The experience to take on any electrical home improvement project is something that is obtained by years of professional training and experience under a Licensed Master Electrician. That kind of experience isn’t something that the average Do-It-Yourselfer has, even if you do consider yourself a Jack-Of-All Trades.

One of the biggest dangers of DIY Electrical work is simply the fact that electricity can be deadly when not handled properly. Many DIY home improvement projects are often done in a hurry, and without proper planning. Something as simple as forgetting to switch off the breaker, using the wrong tools for the job, or even accidentally brushing up against the wrong wire can send high voltage coursing through a human body, easily causing burns, ventricular fibrillation (uncontrolled movement of the heart muscles), and death. We are so accustomed to being able to flip a switch and use electricity in our daily life that we often forgot how powerful it truly is.

One of the major causes for DIY Electrical accidents is unfamiliarity with the electrical circuits in your home. Due to shoddy electrical workmanship in many older homes, it is often difficult to tell which outlets, appliances, and lighting fixtures are on a given circuit, especially if your breaker box was improperly labeled, or if the labeling has faded over time. Most home owners will simply switch off breakers until they see the lights turn off in the area that they will be working, and assume it is safe to start working. This is an incredibly dangerous practice since it is not always the case that all outlets and lighting fixtures in an area will be on the same circuit. A Licensed Dallas Electrician will be familiar with standard wiring practices and will know the proper way to test the circuit that they will be working on to ensure that it is safe.

Another huge benefit to using a licensed electrician for your home electrical work is that they will be well versed in all of the building and safety codes required to make sure the job is done right. The reason that this is important is two-fold. First, it is legally required to adhere to all building and safety codes, and if you ever intend on selling your home or having it inspected for any other reason, a DIY Electrical repair or addition will cause your home to fail inspection if building and safety codes are not followed to the letter, generally costing you more money later down the line to have an improperly performed job repaired. Secondly, and even more important, is the fact that building and safety codes are put in place for a reason. If you are not familiar with these codes or do not follow them, you are putting yourself and your family at risk of electrical shock, electrical fires, and injury or death due to a faulty repair.

A reliable Licensed Dallas Electrician such as ElectricMan Inc. will ensure that any home improvement project involving electricity in your home is completed correctly, in compliance with all of the proper safety and building codes, and will guarantee their work to ensure a successful outcome, and the safety of you and your family.

You might be thinking of buying one of those new-fangled electric cars, and may be wondering how they’re charged. That depends on which car you buy. The three main electric cars (electric vehicles or “EVs”) currently available for middle income families are the Toyota Prius, Chevy Volt, and Nissan Leaf.

Toyota Prius. Let’s say you buy a Toyota Prius. The Prius is a “hybrid.” A hybrid isn’t fully electric. It runs on electricity generated by a battery until the battery is depleted. Then, it turns to burning gasoline. In the case of the Prius, a 2010 model drives about 12 miles on a fully charged battery. But the Prius is continuously recharging the battery with a mechanism triggered by stepping on the brakes.

On the downside, the Prius currently doesn’t come with a “plug in” option. That means you can’t plug it into an electric outlet to charge its battery. However, Toyota is partnering with the EV company, Tesla, to develop a plug-in model that will be available in 2012.

Chevy Volt. The Chevy Volt, which started deliveries in the U.S. in December 2010, is also a hybrid. Unlike the Prius, the battery is not charged when you brake, but by plugging into the electric grid. It has a range of around 35 miles before it must start burning gasoline.

Nissan Leaf. The Nissan Leaf is currently the only all-electric EV available for middle income families. It can’t burn gasoline, but runs only on its battery. It has a range of about 100 miles before you need to start looking for an electric outlet.

HOW DO YOU CHARGE A PLUG-IN ELECTRIC CAR?

Level 1 Charging. Both the Chevy Volt and Nissan Leaf come with a charging cord, called a “Level 1 Charger,” as standard equipment. It looks like an extension cord. You can charge your car by plugging the Level 1 Charger into an electrical outlet in your garage or carport.

The advantage of Level 1 charging is that it’s simple and inexpensive to set up. Hire an electrician to install an outlet in your garage or carport. It will need to be on a dedicated circuit, meaning that no other appliances, like a washer, for example, are on the same circuit. The outlet will need to be the safety version usual in garages and outdoors (a GFI). Also, your electrician will need to check whether your electrical panel should be upgraded in size to handle the increased power demand.

Once the outlet is installed, the EV driver pulls out the Level 1 charging cord that comes with the car, starts charging, and lets the car sit… for a long time. A Chevy Volt battery takes 10 hours from empty to full; a Nissan Leaf takes 20 hours.

Even though Level 1 charging is slow, drivers who have short commutes may be satisfied with it because, if they work it right, they won’t start at empty. They’ll have charge left in their batteries and will simply top off at night.

Here’s how it can work. The 100-mile range of the Nissan Leaf is a lot more than the 33 miles the average American drives daily. If you drive the average 33 miles, you will use only one-third of the battery in a day. If you religiously plug in when arriving home, you will be able to top off at night and leave with a full charge in the morning.

For hybrids, like the Chevy Volt, the issue of leaving home fully charged is less pressing. At about 35 miles, when the battery hits empty, it turns to burning gas. This isn’t good for gas usage, but on the other hand, the driver may suffer less from “range anxiety.”

Level 2 Charging. While you may be able to make Level 1 charging work for you, you also have the option of faster charging by installing a special Level 2 Charger in your garage or carport. A Level 2 charger takes a Chevy Volt battery from completely empty to completely full in four hours; eight hours for the Nissan Leaf. So, even if you totally drain your battery, with a Level 2 Charger, you’ll be able to fill it by morning.

A Level 2 charger requires 240 volts, which is more powerful than house current. A Level 2 Charger is housed in a container about 18 inches around and hangs on the garage wall, sticking out about a foot. When you recharge with a Level 2 charger, it looks very much like filling your tank with gas. You stretch a “hose” over to the recharging socket built into the EV.

A Level 2 Charger is usually purchased when you buy your electric car. If you wish, Nissan or Chevy can arrange the purchase and installation. Nissan has partnered with AeroVironment to supply and install chargers. Chevy Volt has partnered with SPX. When a Leaf, for example, is purchased, the Nissan dealer arranges for an AeroVironment electrician in Los Angeles to look over the new owner’s garage, provide a bid, and do the installation.

The car buyer is free to look for a lower bid from an independent Los Angeles electrician; however, warranties and follow-up repairs on the charger may not be as advantageous.

Consumer Reports estimates that purchase and installation of a Level 2 Charger costs about $2,000. However, the price can vary quite a bit, depending on the distance of the charger from your electrical panel and on whether you need an upgrade of your panel size to accommodate the additional power demands of the charger.

THE FUTURE OF CHARGING YOUR ELECTRIC CAR

Level 3 chargers that can fully charge a Nissan Leaf in 15-30 minutes are currently available in Japan. However, they cost about $45,000 installed. When they come to the U.S., they will most likely be installed for electric trucks, company fleets, or for private cars at shopping malls and at gas stations, where EVs will zip in and out to top off their batteries.

An even faster system is currently being installed in Israel. A Palo Alto company called “Better Place” is building a network of “carwashes.” Only, when you drive your EV in, instead of getting a wash job, your spent battery is pulled out and within a couple of minutes, is replaced with a fully charged battery.

The pressure to be fully charged when leaving home will ease as chargers are increasingly installed in public places in the U.S. In my hometown, Los Angeles, Level 2 Chargers are already available in train stations, the main airport (LAX), the L.A. Convention Center, and other public places. One can easily find the network of existing public chargers on-line. In addition, malls will begin installing Level 2 or Level 3 Chargers as an inducement for shoppers and workplaces as an employment benefit.

There are many electrical hazards in industrial plants including arc blasts, shock and arc flash. These can result in serious injuries. Accidents involving electricity may sometimes be fatal. Industrial plant environments create potential for these events to occur not only to plant owners, but also to maintenance staff.

Electricians often assume that these hazards do not apply to them. These beliefs often persist until a major incident occurs that results in both financial and personal repercussions, that result in a change in policy within the plant.

Implementing policies that encourage a culture of electrical safety doesn’t have to be reactive. Taking steps to minimize the risks associated with electrical hazards will create a safe working environment for everyone, and not just the maintenance team.

One of the most important aspects of enhancing safety is establishing a routine for the maintenance of electrical equipment in the facility. This is not only vital for optimizing the performance of the equipment, but also ensuring reliability, safety and preventing unnecessary downtime.

There are several new models of electric powered cars becoming available as well as others in development.  These electric powered vehicles are the wave of the future.  But, right now, they are expensive (the cost upfront is still significantly higher than their combustion engine counterparts), and there are certain qualities about them that still make people a little bit hesitant to make the switch to a car that needs a charger rather than a tank full of gasoline.

No one can argue that these vehicles offer some significant advantages over cars that run on gasoline, which should seriously be considered high selling points if you’re considering buying an electric car in the near future.  They have the ability to significantly reduce air pollution in metropolitan areas because they have zero tail pipe emissions.  They also have the ability to help decrease our incredible dependency on oil.  It also turns out that electric motors are much more efficient than internal combustible engines – the amount of energy lost in the process of converting electricity into usable motor power is much less in an electric engine than in the standard engine.

Some of the problems that these electrical cars have had in the past (and still make people nervous) have been overcome or are in the process of being overcome.  Initially, the small motors meant slow acceleration.  However, the current electric motors really don’t accelerate significantly slower than other motors.  The batteries that these cars use have also evolved over time and now offer a much better range than early models.

The issues of range anxiety and worrying about charging your car more often than is really convenient most likely won’t disappear completely until there are enough people out there driving electric cars to prove that charging them is no more inconvenient than having to stop at a gas station to fill up regularly, but these are the cars of the future, and the future is closer than most people realize.
