The combination of Greentek’s unique mounting and duct collar systems results in easier and faster installation of the unit including the hard pipe and insulated flex ductwork connections. One person can install the unit in less time than competitor’s units resulting in field labor savings and a more professional looking installation.
The DuoTrol speed control system results in easier balancing of the unit and quieter operation. Competitor’s damper balancing causes unnecessary air noise. Greentek’s variable fan speed control balancing is overall more effective and results in lower fan motor amp draw, saving overall energy usage.
Greentek’s residential lineup is available for applications from 30 cfm to 250 cfm. Light commercial units are available from 300 cfm to 1200 cfm. All units are available with either heat recovery (HRV) or energy recovery (ERV) cores. What is the difference between an HRV and an ERV cores? HRVs and ERVs are similar devices in that both supply and exhaust air to and from a home/building while recovering energy from the exhaust air stream in the process. The primary difference between the two is that an HRV transfers heat while an ERV transfers both heat and moisture.
Accessories include digital and mechanical remote wall controls, wall hoods and diffusers, all in stock at EP Sales.
Please give us a call with your next residential or light commercial HRV or ERV job. We can assist with design and application as well other products that will complement your ventilation project.
If you’ve even heard of gas detectors, then chances are good you’ve asked yourself, “How do gas detectors work. And do I even need them?” This is most likely to be the case if you work in a commercial or industrial environment. However, you may even have asked this in a small office park, apartment building, or at home.
For instance, you might want to make sure you protect your occupants from refrigerant leaks, natural gas, carbon monoxide or nitrogen dioxide poisoning in the garage. Whatever the case, it’s important to understand the purpose and mechanisms behind gas detectors before deciding to employ them at home or in business.
In recent years, the Environmental Protection Agency has taken serious education measures. They want to ensure Americans better understand the nature and danger of gas leaks. With that increased awareness has come an attendant recognition that gas detectors are the best way to combat harmful and potentially fatal gas leaks.
Again, though, we come back to that question: How do gas detectors work? And once you understand that, what are you supposed to do with the information? Let’s dive in.
You may be surprised to know that electric boilers are ideal for certain applications regardless of operational costs. It’s widely known throughout the US that gas boilers cost less to operate than electric boilers. However, there are applications where operation costs alone should not be the only factor in the boiler selection process.
First, gas and electric rates vary greatly depending on where you live. In some areas, each can be up to five times more expensive, so it pays to know the energy costs in the area where you live.
So, you want to heat your home or office and are wondering which option is best when comparing electric boilers vs. gas boilers? To get to the answer, it’s important to ask yourself a couple of questions:
But these two questions aren’t the only things to consider before you make your decision. Let’s take a look at which heat source comes out on top in many applications so you’ll know whether electric or gas models make the most sense.Read More »»

If you want to combat dry air, you need to find the best steam humidifier for your application. So what makes a good humidifier? Let’s discuss whether bypass or steam humidifiers are better. We’ll also look at the cost and effectiveness of steam humidifiers, and reveal a favorite, top-performing brand.
First, it’s important to understand precisely what bypass and steam humidifiers are. A bypass humidifier merely bypasses warm air across a pad wetted by water from the house. The warm air from the front goes through that pad as it would go through a furnace filter. This causes some of the moisture to evaporate, where it becomes humidity distributed throughout the house.
The problem with bypass humidifiers is that they only use, at best, 25 percent of the water that runs through the pad. That means 75 percent of the water goes to waste. Also, a bypass humidifier only operates when the furnace is heating. That’s because you have to have that temperature differential to help with evaporation of the water off the pad.
A steam humidifier generates humidity by filling a tank full of water, heating that tank up so that the water boils and producing steam. The steam leaves through a distribution tube into the ductwork. Then, it’s distributed throughout the house. The device boils off all the water in the tank and doesn’t waste any water in the humidification process. What’s more, a steam humidifier can operate even when the furnace is not running.
So, to sum that up: No water waste + No need for furnace running = steam humidifiers emerging as the best choice for humidification.
Yes, it’s true that bypass humidifiers are cheaper than steam humidifiers. That’s why more people choose to install them. Between their lower upfront installation costs and lower operating costs, it’s easy to see why. Keep in mind that bypass humidifiers don’t need to generate their own heat. They merely wet a pad and use the heat from the furnace. That saves on electricity. Add in the fact that installation costs can be up to three times higher, and the bypass humidifier looks like the better option.
However, there are several scenarios in which you may want to avoid a bypass humidifier:
The last point is especially important to note. A heat pump generates heat, but not at the temperatures a gas furnace can. As a result, the heated air is at a lower temperature than if it were a furnace. In turn, the evaporation percentage of the water is significantly less. So with a heat pump system, a bypass humidifier is less efficient. If you have a heat pump, you really need to go with a steam humidifier that generates its own heat.
Finally, if the application is humidity critical, you will benefit from a steam humidifier. They can generate more humidity than a bypass humidifier. That makes for a better choice for homes with a lot of wood (which soak up moisture) or larger spaces.
One of the best steam humidifiers on the market is the Thermolec. Keep reading for some compelling reasons to take a closer look at this brand.
With a steam humidifier, you must maintain the unit more frequently the harder your water is. However, if it uses elements, this simplifies the maintenance process. Thermolec’s element-style steam humidifier has a 10-year warranty. That means there should be no replacement parts in the first ten years of operation.
The crucial factors to consider are water hardness and operation time:
The difference between a Thermolec and other steam humidifiers is that the cleaning process only takes about 10 minutes. With an electrode-style steam humidifier, on the other hand, the tank and electrodes actually need replacing. You have to disconnect and reconnect wires. The process takes longer. Plus, there is a material expense required that doesn’t exist with a Thermolec steam humidifier.
Finally, the Thermolec unit has a 10-year warranty, unlike others that only have a 1-year warranty. Given that other steam humidifiers have parts to replace every year, that’s a significant distinction.
Ready to learn more about the best steam humidifier for you? Now is the time to call a professional who can walk you through the pros and cons of steam humidifiers. It may also help you to be able to discuss your individual application and make a plan for installing your new humidifier. Now is the time to kill dryness and live more comfortably!
If you are tired of fighting the winter chill and looking for a solution, it’s time to consider electric duct heaters for supplemental heat with ductless heat pump systems. When the temps fall below freezing, most heat pumps struggle to get the necessary heat energy from the outside air. This leads to less than cozy indoor temperatures.
The key to achieving comfort on colder days is having a supplemental heat source set to operate automatically with the heat pump system. This is where ductless heat pump systems along with ducted indoor fan coils come in to save the day.Read More »»
From increased efficiency and comfort (no drafts like from forced-air heating systems) to keeping allergies at bay, the compelling benefits of hydronic radiant floor heating have become increasingly popular with homeowners everywhere. Hydronic radiant floor heating circulates hot water through tubes in floors throughout a home. It has many advantages over traditional heating systems that are making it a popular option for all kinds of property owners.
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.
Sentinel X500 protects all system metals against corrosion using the same unique blend of inhibitors as Sentinel X100 with the added benefit of freeze protection.
X500 is a multipurpose inhibited antifreeze for hydronic heating systems. It is formulated to help control corrosion, scale, boiler noise and hydrogen gassing in all types of indirect heating systems including those containing aluminum components.
The non-toxic formulation is colorless, easy to handle and is suitable for use in all waters, both hard and soft. If minimum levels are maintained, the product ensures a permanent protection and does not need to be replaced.

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.
