Using Glycol in Hydronic Heating Systems

hydronic-heating-systems-image

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.

Gas Monitoring Systems for Vehicle Emissions

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.

The Problem with Vehicle Emissions in Enclosed Parking Garages

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.

Residential Mechanical Ventilation – The Minnesota Solution

Minnesota-Residential-Code-2015

The state of MN has been at the forefront of adopting residential building codes that incorporate energy efficiency designs for residential mechanical ventilation. These codes have additional provisions which address some of the serious side effects such designs can have on the home’s inhabitants and structural integrity.

Back in the early 1980’s, these energy efficient building designs introduced highly insulated air tight homes. These designs significantly reduce a home’s energy consumption but created adverse consequences that could not go ignored. Extensive research conducted over the past 30+ years was the driving force behind the current 2015 Minnesota Energy Code. Considered controversial by the builders and realtors, primarily due to the code’s cost impact on a home’s sale price, this code is also viewed as a showcase for all the advocates of the advancement of building science.

Using Supplemental Electric Duct Heaters in Heat Pump Systems

supplemental-heaters-in-heat-pump-systems

Homeowners are increasingly relying on VRF heat pumps and ductless mini-splits to keep their families warm during the heating season. At the same time, commercial property managers are relying more and more on these devices as well, thanks to the ease of installation, simple controls and unparalleled flexibility that they offer.

VRF and ductless mini-splits represent some of the most efficient kinds of heaters on the market. Whereas propane and oil heating systems rely on expensive fuels to operate, these heat pumps produce indoor warmth in a cost-effective, environmentally friendly way.

However, heat pump mini-splits can be overtasked when dealing with subzero temperatures. These conditions cause HP’s to eliminate the efficiency that makes them so desirable and to produce less heat affecting the comfort of the living space.

Installing an electric duct heater for supplemental heating is one of the best ways to address this dilemma. The result is a far more efficiency in terms of the overall system’s Heating Seasonal Performance Factor (HSPF).

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.

Common Applications for Electric Duct Heaters

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:

  • Forced Air Furnaces
  • Heat Recovery Ventilation
  • Tempering outdoor air
  • Makeup Air

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.

How Do Ductless Air Conditioners Stack Up Against Traditional Units?

ductless-air-conditioning

When it comes to residential and light commercial heating, ventilation and air conditioning, a fast-growing market segment is quickly developing into an industry-leading trend. Ductless air conditioners, also called mini-splits, are increasingly replacing the large, bulky window-mounted systems of yesteryear. Is this a passing fad, or are there real benefits to be enjoyed by installing one of these systems in your home or workplace? Read on to find out.

 Ductless Heating and Cooling: Advantages and Disadvantages

 The main difference between these new systems and traditional window air conditioners is that they are smaller, more efficient and more flexible when it comes to mounting and placement. Mini-splits allow homeowners to selectively heat and cool individual rooms according to their occupants’ desires by connecting a single outdoor unit to multiple indoor air controllers.
