If you’re asking yourself, “Why do I care about radon mitigation systems?” don’t worry: you’re not alone. A lot of homeowners focus on things like electrical safety and protection from fires and carbon monoxide. Few give a second thought to radon, and they pay dearly for it.
Radon is a radioactive gas found in the earth’s crust. It seeps up from below, poisoning the air you breathe. But you’d never know it.
Colorless and odorless, it’s difficult to detect without special equipment. Radon gas is a byproduct of uranium, occurring when the element begins to decay naturally. This gas eventually works its way to the surface, poisoning the air around you.
Over time, this exposure can lead to lung cancer. In fact, long-term radon exposure was the reason attributed to over 21,000 deaths just last year. It is the second deadliest contributor, behind smoking, and the most lethal contributor amongst non-smokers.
Glycol, also called antifreeze, is an important compound that HVAC manufacturers use to protect hydronic heating systems in cold climates. When added to water, glycol lowers the freezing temperature of the resulting mixture, ensuring that it remains liquid even during harsh winter weather.
Without glycol, simply leaving the heat source off for more than a day or two could result in the entire system freezing up; causing ice which will likely burst pipes and create extensive water damage to a dwelling. Adding glycol to the water prevents such catastrophes from happening, but often compromises system performance. However, high-quality glycol can mitigate that risk.
As the growth of multi-family residential housing units has increased in recent years, so has the number of enclosed parking garages. Builders and planners recognize that tenants prefer enclosed parking garages for convenience and comfort. Such garages are a definite selling point in northern states where snow clearing is a major issue. However, with such enclosed parking areas comes a significant danger.
Even though enclosed parking garages are very attractive to tenants, keeping the air healthy should be a concern for building owners. Cars in enclosed spaces can produce high levels of carbon monoxide (CO), and diesel engine cars can produce high levels of nitrogen dioxide (NO₂). Both emissions are very dangerous and pose significant safety concerns to human life. Human health effects can vary significantly based on the state of health, age, sex and weight and exposure over time to low concentration levels can lead to respiratory problems, lung damage and neurological problems. Toxicity levels are well-documented and death can occur in a matter of minutes.
If you’re in the process of building a home and want to keep it filled with fresh, healthy air year-round, then you have an important decision to make – which ventilation system to add to your HVAC package.
The most effective ventilation options available for residential homes are HRVs and ERVs. In order to choose the right one for your home, it’s important to understand the differences between the two products.
Electric duct heaters are a convenient, affordable and effective way to provide heat to a room or ventilation duct system. Professional HVAC contractors have used these devices in residential, commercial and industrial HVAC systems for many years.
The main idea behind heating with an electric duct heater is adding heat to the air inside the duct in an efficient manner. Electric duct heaters can be used in a broad range of applications, some of the most popular of which are:
When choosing an electric duct heater for your home or workplace, you’ll want to keep the specific application in mind when deciding the model you need.
If you have a high-powered, commercial-quality cooktop installed in your kitchen, chances are you also have a makeup air unit installed in your home. This device compensates for the amount of air being pushed out of your kitchen’s extractor and breathes fresh, room-temperature air in from outside. Makeup air units are typically automatic—unless you had yours recently installed, you may not even know you have one, but you’ll notice if it breaks down.
If your cooktop comes with a large extractor hood that sweeps out odors and contaminants from your home, your makeup air system is what’s responsible for replacing the lost air. Without it, your home would be depressurized and the kitchen hood would soon be unable to push the air out. The fumes would collect inside your house—creating a dangerous environment for you and your family.
Heating your home with a heat pump is energy efficient and cost-effective. When dry indoor air becomes a problem in winter, however, you’re likely to find that the central humidifiers that work just fine with fossil-fuel-fired furnaces aren’t as effective when used in conjunction with a heat pump. Fortunately, a steam humidifier may be the solution to the problem.
Thermolec Acu-Steam humidifiers are the most dependable and easiest tomaintain steam humidifiers on the market.Acu-Steam will tolerate a variety ofwater conditions, it’s unique design includes self-cleaning elements enclosedin a quick release stainless steel tank, eliminating the need to buy costlyreplacement tanks.Element and tank carry a 10 year warranty. A pressureswitch is included as a standard feature, assuring that steam is not introducedinto the ductwork if the system fan has failed. Three sizes cover from 13to 37gallons per day.
The Thermo-Air (TER) and Thermo-Zone (ZON) electric duct heaters are unique to Thermolec. Both are available with 6” – 12” round duct connections and up to 12 kW of electric heat in single phase power. Both units come with an electronic airflow sensor and duct temperature sensor. The TER has a duct stat to control temperature in the duct. The ZON comes with a wall stat to control room temperature. Both units are fully modulating so only the right amount of energy is used to maintain temperature.
Thermolec is one of the top three custom duct heater manufacturers in North America. They can build any size and any configuration of electric duct heater. They specialize in open coil element heaters and have the shortest lead times in the industry. Thermolec’s advanced electronics give designers the superior option of modulating control at a staged heater price.
