Choosing the right heating system for maximum efficiency

Purchasing the right heating system lets homeowners enjoy their homes comfortably, it also also allows for optimum heat output that won’t lead to debt. There are unique heating units in modern HVAC markets.

Deciding to replace or purchase a new heating system can be quite stressful everyone isn’t educated on the pros and cons of the different systems which are:

  • Furnaces
  • Heat pumps
  • Radiant heating

We have different furnaces available for homes. A furnace is a heating device that takes air from a home via different ducts and vents. This air is then stored in somewhere for warming and then circulates it throughout your home.

Heat pumps come in two unique types i.e. ground source and air source. The ground source models are known as geothermal heat pumps while the air source type uses the warm exterior air as the primary source of heat. They pull heat from beneath a surface to heat a home. This type saves energy better and there could be a need to use a hot water heating system.

Radiant heat comes in various forms either in hydronic systems, floor heat or radiant ceiling and radiant baseboard heat. This type of heat has lengthy metallic units with electrical systems attached within.

The radiant heating units are separately controlled with a thermostat. These units can be used as the main heat source or as the auxiliary form in areas that are colder in a home.

The best options for heating systems may be:

  • Electrical
  • Natural gas

Electrical heating units runs via heating elements where the resistance generates and spreads all through your home. The heating elements are kept in a furnace, or sometimes in an installed baseboard on the bottom of the wall.

Electrical service may be modified as required by the heating system’s load requirement. An electrician may be needed to install a baseboard heater. This keeps the house and its occupants safe.

Natural gas is efficient. The Annual Fuel Utilization (AFUE) shows the how resourcefulness of the units during the heating months. A furnace with an AFUE of 95% delivers 95% of natural gas energy needed in the home throughout the heating season.

Heat is created when boilers boil water. It then distributes it to other areas in the home via the heat exchange units. These boilers are available in different effective levels. They are- mid-efficiency boilers with an AFUE rating of 85% and high- efficiency boilers of 90% rating.

No matter how well a heating system has been maintained, it will eventually wear out. When this happens, it needs to be replaced. Most people find it easier to replace their systems with a similar type.

Different options are available when you want to select a heating unit. You can pick one that provides cooling and warming functions or two separate delivery units. Identifying the type of heating that works best provides the home and family with comfort levels they desire.

MAINTAINING YOUR HOME

When faced with the option of doing some home improvement project in our homes, we often find it challenging determining which part of the home to give prior attention. Our home is composed of different parts and can be categorized into the exterior and interior part if the home. This little knowledge can help us determine which part of the home need the most attention either for maintenance or improvement. A house is made up of a lot of different parts that are all related and depend on the other parts. For example, if you have a leak in your roof, it can not only damage your roof, but can cause you to have problems with your ceilings, walls, and your electrical system as well. So, it’s very important that you fix a problem when you detect it.

 

Exterior Part: When you think of the exterior part of your house, you think of the outside portion of your house. The exterior of your house is made up of five major areas viz the foundation, siding, roofing, windows doors and yard.

  • Foundation: The foundation of your house supports every other thing in the house, you need to conduct periodic inspection and put in place maintenance measures for your home foundation. Such measures include but no limited to landscaping, drainage and water runoff, Plants should not be planted next to walls of your house. Flowerbeds should be planted several feet from the house. This allows for adequate drainage of the soil and limits the moisture and condensation.
  • Exterior Wall Routine Maintenance: As part of your inspection, you should include routine maintenance through periodic cleaning, caulking, painting or staining and any simple preventive repair jobs on an as-needed basis. One of the simplest maintenance chores for your walls is to simply hose down your siding and trim to remove dirt and grime. Painting and StainingIf you keep the paint on your house in good condition, the joints and seams well caulked and the wall surfaces clean, you will greatly reduce the chances of wood decay and moisture getting into your house.
  • Roof and Gutters: The roof and the different parts of the roof, such as the flashing, drains, gutters and downspouts, cannot be ignored year after year.

 

 

Interior Part: The interior walls, ceilings and floors of your house form a surface that covers the structural frame, plumbing, electrical system, heating and cooling ducts and other building components that would be unsightly or hazardous.

Sagging Ceilings and Walls: When inspecting your ceiling and walls, first make sure your room is well lit. Then look carefully at your ceilings and walls. Sagging ceilings may be a sign of loose wallboard or plaster and should be inspected more closely. Bowed walls may indicate a weakness in the structural framework.

  • Stairways: Stairways are areas where accidents frequently occur. Make sure that handrails are securely attached to the walls and extend the length of the stairs.
  • Bathrooms and Kitchens: Bathrooms and kitchens need extra attention because of the constant presence of moisture.

 

AIR CONDITIONING SYSTEM IN HVAC

The AC in HVAC stands for Air conditioning. Air conditioning refers to the process of getting rid of unwanted heat and moisture from the interior ambient environment of a space occupied by people. The air conditioning system is installed in interior space to provide thermal comfort for occupants of the room. The air conditioning system is installed in all kinds of interior environment as long as it is inhabited by people even animals. Also we can find the air conditioning system installed in places where electronic devices like computer servers, power amplifies that generates much heat to provide a cool environment free of humidity. So air conditioning systems are installed in the interior of residential apartments, office spaces and other form of commercial space, cars and buses, airplanes, boats and ships.
Air conditioner employs a mechanism that uses fan to distribute air that has been conditioned to an occupied room. The conditioned air provides thermal comfort and improves interior air quality. This cooling can either be achieved through what is called the refrigeration cycle or desiccants. Air conditioning system can be based on electric refrigeration. This type of AC units range from small units that can keep a small bedroom cool, (such units can be carried by a single adult) to massive units that are technically installed on the roof of office towers that can cool an entire building. On the other hand AC units can also be based on desiccants (chemicals effective in the removal of moisture from the air). We could also have AC units based on subterraneous pipes which can distribute the heated refrigerant to the ground for cooling.

Types of Air Conditioning System.
1. Cooling Only Split-System: This AC system combines indoor air handling unit and an outdoor condensing unit. The split systems are commonly found in residential or small commercial buildings. One advantage of these systems is that they have the highest energy efficiency rating (EER) of all the available AC systems.

2. Cooling Only Packaged-System: A packaged system as compared to the split system is a single unit. It combines all the components that are described in the split system. The packages system typically works in a way such that it is installed outside the building and the air indoor is “ducted” from the building to the system and back through an air distribution system.

3. Chilled Water System: The chilled water system provides cooling though the pumping of liquid water throughout the building to “chilled water coils”. A cooling plant is needed for the water to be at a cold temperature. This cooling plant is typically referred to as a chiller plant.

4. Window Air Conditioners: As the name suggests, the window air conditioner is typically installed in a window or fitted in an opening in the wall. The window areas is limited in the size of space it can cool. It is built to cool small spaces.

Benefits of an Air Conditioning System:
• It provides thermal comfort to occupants in the room.
• It helps in reducing the risk of skin irritation caused by heat.
• It provides occupants in the room with a relaxing atmosphere.

Surviving winter with your HVAC system

Winter can be a particularly tough time of the year. Even during the Christmas cheer, the thought of having to brave the biting cold is enough discouragement to not want to get out of bed. HVAC systems help us get through these tough times. You get to wonder sometimes how the folks in the ice age got by through just fires without having a nice furnace or some other heating system circulating warmth. Since HVAC systems are so important to our survival during the cold days of winter, it is only logical that we also do all we can to get these systems working perfectly without breaking down. Being stuck with a faulty furnace on a very cold day is better imagined than experienced. Below are a couple of ways to ensure that your heating system keeps functioning properly
• Deal with the dust: The accumulation of dust is a very big threat to your system. It is capable of damaging not just the heating system but even the vents responsible for letting out collected air from interior spaces. Air filters are meant to remove most of the dust, but even these filters do get clogged by the very dust they’re meant to remove. A sure winner in keeping your heating And HVAC system generally safe is by cleaning out your filters often and changing them occasionally.
• Have the system checked out: Even without any obvious damage or faults, make it a habit to schedule frequent inspections by maintenance technicians on your system. Nipping minor faults in the bud will definitely prevent big breakdowns in the future. Prevention they say is better than cure.
• Fuel: This is a basic point but can lead to quite embarrassing situations. If your heating system isn’t dependent on electricity and makes use of some sort of solid or liquid fuel, be sure to always be conscious of your fuel levels. Running out of fuel especially during off-work periods like holidays can result in an uncomfortably cold experience until you are able to purchase some. Stocking up fuels- especially liquid at home is definitely not a good idea, so it’s better to frequently check up on your fuel levels and be sure you have sufficient to last for quite some time.
• Check the controls: While you want to stay warm on cold nights, you equally don’t want to pay excessively high energy costs; we all make occasional mistakes and it’s always quite possible that you have left your thermostat set to a temperature higher than what you require. You may not notice this early enough since you just want to feel warmth. However, over time, energy costs mount (either as electricity bills or fuel costs) additively from the subtle and unnoticeable extra heat being consumed. Occasionally checking your controls and setting the heat to just what you need to keep warm (well, maybe just a little higher) will save you quite some cash at the end of the winter season.

Delivering Customer friendly HVAC systems

Either you’re building a new HVAC system totally from scratch or you’re trying to modify an existing one for a different application or a more optimized and efficient operation. You have to do it with the customer in mind. Nobody would buy a system that they can’t readily figure out no matter how advanced the technology is. Your system has to cater not just to the needs of the buyer. It also has to ensure that the buyer can use it easily without having to consult the manufacturer at every point in time. The points we will discuss here will help you to design, develop, build and maintain HVAC systems that buyers would love.

• Break down the user’s guide: Engineers and technicians often forget that the user’s guide is not meant for other engineers but for laymen. Technical language, complex diagrams and complicated illustrations which help to pass along information quickly among professionals can be a significant headache for end users. Be conscious of “dumbing down” the content of your users’ guide. A saying once attributed to Alber Einstein was that “If you can’t explain it to a 6 yr old, you don’t know it well enough”. You could imagine you are trying to explain the operation of the system to a 4th grader. If you’re still not sure, run it through a couple of non-tech family or friends and see if they can understand it.

• Make the positioning of controls intuitive: The focus of engineers on utility and practical use may often clash with the established intuition and long-term understanding of everyday users. In placing controls like thermostat and on/off switches, put yourself mentally in the position of the user and ask “would this be comfortable?” The user only sees the system exterior and is most likely oblivious of the occasional trade-off between aesthetics and functionality. To keep users satisfied, you need to bring yourself to be able to view the systems from their point of view.

• Accessibility to parts: HVAC system components like air filters and others that require regular cleaning should be positioned in locations that are not too obscure. Although some may argue that it will lead to users tampering with parts and damaging the equipment early. It is, however, important to note that maintenance personnel will find their job easier if they do not have to go through sheets and sheets of exterior metal just to carry out routine maintenance.

• Detailed PID diagrams: This is more for the professionals than the users. But in the end, anything that makes an HVAC system function properly will definitely make the user happy in the long run. Ensure that P&ID diagrams represent every aspect of the instrumentation. Maintenance guys will be able to trace faults more easily. In the event of a future remodification, unnecessary damage won’t be done due to ignorance about unique wiring or piping configurations.
Customer satisfaction is a top priority in developing products that will take the market by storm and we hope these points will help you achieve just that.

Five Signs that Your Ductwork Need to Be Replaced

Does the condition of your ductwork really matter? Should I even care about my ductwork? Well, this article explains some of the signs that will help you know when to replace your ductwork. Of course, you’ll also get to understand the condition of your ductwork matter. Your ductwork is responsible for delivering cool or warm air within your living space. Any issues or problems in your ductwork can affect the performance of your HVAC unit and even shorten its life.

If the HVAC ducts in your home get damaged or become defective, your system will be forced to work harder to distribute air throughout your home. It becomes quite difficult for your HVAC unit to keep your home comfortable. Replacing the air duct system of your unit can help maximize its efficiency and make your home more comfortable. It’s important that you hire a licensed technician to replace the defective or damaged ductwork. He will ensure that air ducts of the correct size are fitted within your house and all connections between vents, ducts, and registers sealed. Here are some the signs that would indicate the need to replace your air duct.

Constantly Dusty Home

One of the reasons your home has been dusty on a continuous basis is the presence of leaky ducts. When your ductwork develops leaks, it is obvious that cool or warm air will easily escape while dirt and dust particles get their way in. Ignoring this problem can result in serious issues in your HVAC unit which would lead to an unsafe and unhealthy home environment.

Mold in your Ducts

Mold usually develops in a moist environment. The fact that your HVAC unit is allowing the passage of cool and warm air through it means that, over time, moisture can develop and result in mold growth. How would you know if there’s mold in your ductwork? Simple, strange odor from your air vents. As soon as you smell any strange odor from your ductwork or air vents, have them inspected for mold growth.

Inconsistent Room Temperatures

As mentioned, the air ducts play a critical role in sneering your home remains at a comfortable temperature. They deliver warm or cool air throughout all the rooms in your home. If you notice any inconsistency in the temperatures in your home, chances are there could be a problem with your HVAC ducts. Inconsistent room temperatures, in this case, means some of the rooms are too cold while others are too hot.

Noisy Central Air System

An undersized ductwork would result in a lot of noise. In such cases, you need to hire a licensed HVAC technician to check if you have the correct size or if there’s another problem. If your ductwork is undersized, you’ll need to replace it with the proper size ductwork.

High Utility Bills

If you’ve been paying high energy bills in a recent couple of months, there could be a problem with your HVAC system. The high utility bills could be as a result of leaks in your air ducts. The presence of leaks would mean you’re losing a lot of energy each day hence the increasing utility bills. A licensed HVAC technician can conduct a run a blower test to determine if there’s a problem with your ductwork. If there are leaks, he can replace your ductwork to keep your energy bills affordable.  More info
