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).

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.

The Homeowner’s Guide to Inspecting and Maintaining Makeup Air Units

makeup-air-unit

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.

Use a Steam Humidifier to Help Your Heat Pump Fight Dry Winter Air

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.

ECR Announces the MAC/DCB Self-Commissioning Condensing Boiler

We are very excited to announce ECR’s new line of self-commissioning, condensing gas boilers.  The Utica MAC and the Dunkirk DCB are both 95% AFUE and use [AI] Control Technology. The [AI] Control self-commissions and continuously calibrates to ensure maximum efficiency at all times. It measures water temperature, flue gas temperature, flame signal and pressure – conditions that can impact the boiler operation and CO levels. The [AI] control will automatically shut down operation should these values exceed normal operating levels. This provides added protection for you and your customer.

Available in both a heating only model (125mbh input) or a combi (153mbh domestic input, 125mbh heating input), the MAC/DCB offers excellent turndown in both heating (5.7:1) and DHW (7:1).

The MAC/DCB offers an intelligent condensing approach to today’s residential heating and domestic hot water needs.  Give us a call for a live fire demo of this exciting new product from ECR.

Residential Makeup Air Now Required by Code

Did you know that most states require makeup air be provided when a home has a large range hood exhaust system?  Minnesota Mechanical and Fuel Gas Code Chapter 1346 bases it’s requirement on the cfm of the range hood exhaust and the type of combustion appliances in the home.  In other states the International Residential Code applies and it’s threshold is 400 cfm or larger.

Meeting these code requirements has been simplified by Thermolec’s FER and NER model makeup air units.  Both include a filter, backdraft damper, speed controllable fan and modulating electric heating section.  These units come with a current sensing relay so when the range exhaust fan draws amps, the makeup air unit fan starts automatically.  These units are a simple and easy way for the installer to meet the makeup air requirements of the code as well as an effective way to provide tempered outdoor air for other light commercial applications.
