What You Should Consider Before Upgrading the Heating System in Champaign

Monday, September 17th, 2012

Many Champaign homeowners who heat their homes with an older heating system—whether it’s a furnace or a heat pump—may want to consider upgrading to a more efficient system. Older furnaces with an AFUE rating of less than 80%, for instance, could be costing you a lot more than you realize in heating bills.

While it is a significant initial investment, upgrading to a more efficient furnace or heat pump will pay for itself in energy savings. Before you decide on whether or not an upgrade is right for your home, here are some things to keep in mind.

Fuel Costs

Some types of fuel, such as electricity, are more expensive in certain areas. Depending on where you live, you may want to compare the cost of fuel before choosing a heating upgrade. In fact, natural gas may or may not be available to your home. Check with your utility company to find out what types of fuel are available and which ones would be more cost-efficient for heating your home. You can always call a qualified Champaign heating technician if you have any questions about a heating system upgrade.

Insulation

Whenever you are thinking about upgrading your heating system, you’ll want to make sure your home is properly insulated and sealed. If you purchase and install a highly efficient furnace, it won’t save as much in energy bills if your house is poorly insulated. Get a home energy audit with a local energy resource organization if you aren’t sure. You might want to also consider upgrading your old windows and doors, or installing storm doors and windows to improve air tightness.

Property Value

A lot of homeowners forget that any upgrade or remodeling project will increase the value of their home. Not only will a heating system upgrade lower your heating bills; it will also add value to your home and property. Always make sure you choose the right system for your home so that it lasts as long as possible.

If you are considering upgrading the heating system in your Champaign home, call Lanz Heating & Cooling to speak with one of our HVAC experts to ask about our quality products and installation services.

Urbana Heat Pump Tips: What is a Heat Pump Reversing Valve?

Monday, May 14th, 2012

As conventional energy resources dwindle and become more expensive, alternatives increase in popularity.  Heat pumps in Urbana, like the natural heat they harness, are fast rising to the surface.

Tapping the stored energy of the greatest solar collector in existence, geothermal, or ground source heat pumps (GSHPs) are electrically powered systems that tap the earth’s relatively constant temperature to provide cooling, heating, and hot water for homes and commercial buildings. Simple, efficient and abundant, heat pumps are best used in moderate to hot climates where the differential of temperatures is not extreme.

General Heat Pump Information

Functioning on the same principle as refrigerators, the heat pump uses a liquid to absorb heat as it turns into a gas and release heat as it returns to a liquid state. During the summer, the heat pump operates as a standard central air conditioner, removing heat from the house and venting it to the outside.

In the winter, the heat pump reverses this process, extracting heat from the cold air outside and releasing it inside the house. The heat pump is very efficient when the outside temperature is around 45 degrees Fahrenheit to 50 degrees Fahrenheit, but it becomes less efficient as the temperature drops.

The Heart of the Matter

The reversing valve in the heat pump switches the process from absorbing heat from the inside to evacuate outdoors like an air conditioner to extracting heat from cold temperatures outside and redistributing it indoors.  The thermal energy at play is the natural force of heat to move toward cooler temperatures, releasing energy in the shift.  Heat pumps take care of both and the reversing valve controls the direction of the flow.

The reversing valve has two states of operation: relaxed and energized.  In the relaxed state, the heat pump can be programmed to introduce either heated or cooled temperatures into the conditioned space, depending on the direction of the flow of refrigerant through the closed loop.

By applying a 24 volt charge of AC current (a low voltage typically used in HVAC systems), the valve becomes energized and reverses the flow, producing the opposite conditioning.  The reversing valve may be driven by the heat pump through the use of a control board or directly by a thermostat.

As energy resources rapidly change in cost and supply, heat pumps utilizing geothermal energy are looking like a viable alternative in today’s market.  Please call Lanz Heating & Cooling to learn more about geothermal heat pumps

How Much Electricity Does a Urbana Gas Furnace Use?

Monday, April 9th, 2012

The answer to the question “How much electricity does a gas furnace in Urbana use” could sound like the lead-in to a silly Groucho Marx joke: “None, because it’s a gas furnace! HONK!”

In fact, electricity is necessary for several important tasks as part of the more efficient gas furnaces.

Lighting the Torch

Gas is the fuel that fires the flame that heats the air that warms your home, but electricity is the spark that lights the gas.  The flame is not roaring all the time or just ignites spontaneously.  Think of the athlete igniting the Olympic torch.

A low voltage electric signal from the thermostat opens the valve that controls the amount of gas flow and therefore the flame.  A solenoid coil in the valve senses gas and ensures flame to prevent an explosion or leakage, then opens wide to let the heating begin and shuts down when the desired temperature is reached.

Blown Away

All that heated air must be moved through the ductwork and distributed room to room to create the comfort and this is done by a motor-driven fan which is the largest use of electricity in a gas furnace.  The motor turns on and shuts down according to the relationships between flame, heated air and the thermostat setting.

Known as a draft inducer, a second fan is employed to remove the toxic fumes that are the residue of the burned gas.  These fumes which can be deadly are usually pushed through a PVC pipe to the exterior and released safely into the atmosphere.

Sum Total

The amount of electricity used to ignite the flame is very small, phased through a low-voltage impulse wire, nearly too small to even show on your meter.  Most of the electrical energy contributing the critical role of powering the two fans in gas furnaces adds up typically to less than 600 watts at any given time or about the same as a few light bulbs.

While gas furnaces are much more efficient and less costly than any kind of electric heat, they are useless (and even dangerous) without that little bit of electrical help.  Call Lanz Heating & Cooling with any questions.

Champaign County Q/A: What Is a Flapper Valve?

Friday, February 17th, 2012

Toilets in Champaign County are not an overly complicated piece of equipment. But in order to work properly, it does require that all of its parts are in the right place and in good shape. Even if something small on your toilet is out of place, it can cause problems like constant dripping or running, improper flushing force or a sudden refilling of the bowl when no one has flushed the toilet.

These problems can sound serious, but many of them only require minor plumbing maintenance if you know where to look. With most toilets, that place is the flapper valve. The flapper valve is a relatively small rubber plug that fits over an opening at the bottom of your toilet tank. When you press the handle to flush your toilet, the flapper valve lifts up and allows all of the water from the tank to go rushing into the bowl.  Without this piece you will be in need of plumbing maintenance.

The force of this water pushes everything out of the bowl through the drain at the bottom, clearing the bowl and refilling it with fresh water all at once. As long as the flapper valve is able to maintain a tight seal, this process will go along smoothly without a hitch. But sometimes these valves become dirty or simply wear out.

When that happens, water can begin to leak down from the tank into the bowl on an almost constant basis. Depending on the severity of the leak, this may just cause the toilet to run constantly. Or it can even cause periodic “phantom flushes” were the toilet clears the bowl without anyone pressing the handle.

Phantom flushes occur because too much water has seeped down from the tank into the bowl. When the volume in the toilet bowl reaches a certain level, the water in the bowl is forced out, resulting in a flush. This wastes water and can also be pretty startling if you are not expecting it. Fortunately, though, you can usually fix this problem easily enough.

To do this, check your flapper valve to make sure it is keeping a tight seal with the bottom of the tank when not in use. If it is not, you may only need to clean it off to restore the integrity of the seal. In more serious situations, however, you may need to replace the flapper valve entirely. This plumbing repair is not difficult or expensive and can save you a lot of water in the long run.  If you need any help please call Lanz Plumbing.

Royal Boiler Repair Tip: Reasons for Poor Heating Performance

Wednesday, January 11th, 2012

You don’t have to be a rocket scientist or a mechanical engineer to troubleshoot – and possibly diagnose – the problems with your Royal home’s boiler when its heating performance is erratic or non-existent.

The good thing about boilers is that they are typically reliable and long-lasting. There aren’t a lot of working parts that can break down and cause problems, compared to other home heating equipment. When problems do arise, they are usually related to the expansion tank or circulating pumps. But a problem can be much simpler – like a tripped circuit breaker.

The most common problems can be noise, no heat, or poor/erratic heating. Before calling a qualified heating and cooling professional, take a moment to see if you can figure out the what’s wrong.

If you have a noisy boiler it might be because of two things – a faulty circulating pump or water trapped in the return lines. If the pump breaks it will make a loud noise when its motor runs. Water can be trapped in the return lines, which may require “re-pitching” the lines to allow for a flow back to the boiler. You may be able to adjust the flow by positioning hangers on the piping but replacing a pump is better left to a professional.

If your boiler is producing no heat, it could be because of something as simple as a circuit breaker being tripped or a fuse being blown. Check your circuit breakers and fuse and reset or replace if necessary. Is your boiler thermostat in the heat mode? It should be but if it isn’t, make the switch. If your boiler has a standing pilot you should check to see if it is lit and if not, re-light it.

Other problems would take a professional to fix. For example, no heat can be traced to low water levels in the boiler. The boiler should always be half-full of water and if it isn’t, it is likely because of leaks or a faulty pressure reducing valve. Don’t try and fix the problem by yourself.

Low water levels may not cause the boiler to lose its heating capabilities, but may cause fluctuations in its heating capacity. Again, it is advisable to call a Royal heating contractor to diagnose and fix the problem. Poor heating can also be traced to mineral deposits in the boiler. Consult your owner’s manual on instructions how to flush out the boiler.

As always, read the owner guide or operating manual for your boiler. You should get some good tips on proper maintenance and troubleshooting. And have the phone number of a qualified professional taped to your boiler – just in case.

A Question from St Joseph: What Is an Air Source Heat Pump?

Monday, December 26th, 2011

Most heating systems in St Joseph have as their main component some sort of heat generator, such as a furnace or boiler. These machines generate heat through some form of combustion, which obviously converts energy directly to heat, which is then distributed throughout the home. That’s a pretty simplified schematic explanation, but that’s more or less how most heating systems work.

Air source heat pumps are another type of heating solution; one that does not actually produce or generate any actual heat. There is no combustion. What an air source heat pump (ASHP) does instead is regulate the temperature of the home by essentially moving air around.

An air source heat pump use electricity to exchange indoor and outdoor air. Think of it like a more versatile air conditioner. In cooling mode, like an air conditioner, an ASHP will pump warm air from the inside out, using a system of refrigerant-filled coils and a compressor. By turning the ASHP to heating mode, the refrigerant flow is reversed, allowing the outdoor coils to extract heat from the outdoor air and pump it in higher concentrations to the inside.

If it seems like a simple system, that’s because it is. All the heat pump does is move heat either in or out, depending on what you need in the current season. Because this process generates no heat on its own, heat pumps can be very efficient. ASHP efficiency has been estimated at 150% to 300%, meaning that the heat energy produced is up to three times as much as the electricity used. That makes for a very efficient home heating and cooling solution.

Air source heat pumps are not necessarily right for every situation, however. In colder climates, where temperatures drop below 30 degrees Fahrenheit for stretches at a time, a heat pump will likely not be able to keep up on its own. In these situations, you may either need to supplement the ASHP with an additional heating source, or use a different system altogether. Newer so-called “cold climate” heat pumps may also be an option. Under ideal circumstances, an air source heat pump can act as a complete home heating system, as well as providing heat for hot water.

If you are looking for a simple and efficient home heating solution, look into whether an air source heat pump can work for you.

Open vs. Closed Loop Systems in Geothermal: A Guide From Tolono

Friday, August 26th, 2011

Even people who are somewhat familiar with geothermal heating systems may not be aware that there are actually two types – open and closed loop systems. The difference, of course, is that the closed loop systems make use of a completely sealed loop of pipe filled with water, antifreeze or some combination of these that cycles through the pipe absorbing heat and transferring it to your Tolono home.

Open loop systems, on the other hand, are linked to a well casting and draw water from there to circulate throughout the system as a heat source. Particularly if you already have an appropriate well casting in place, you can often save a lot on your installation costs by putting in an open loop system rather than a closed loop.

If you do not already have a well, however, the installation of an open loop system might still be cheaper but not by as much. Also, the costs of operation after the initial installation are pretty comparable, so the relative costs associated with operating one type of system or the other should not weigh to heavily on your decision.

In fact, the best way to decide which type of geothermal heating system is right for you is to talk to an experienced contractor about your particular situation. They will be able to tell you exactly what the installation of each type of system will entail in your specific case and make informed recommendations about what type of system will work best for you.

No matter what type of geothermal heating system you do go with, though, you will be getting an excellent and inexpensive home comfort solution that will keep your indoor temperature at the right level all year round. That is because geothermal heat pumps, just like air source heat pumps, can be reversed during the warmer summer months to actually remove heat from your home. That way, you can stay cool in the summer and warm in the winter without having to pay for heating or air conditioning. If you have more questions about if geothermal is right for your home, contact your local professional.

AC as a Safety Feature in the Home: A Tip From Springfield

Wednesday, August 10th, 2011

Ask a hundred people in Springfield today what the primary role of air conditioning is and I’ll bet you they say “comfort”. We seek out AC to stay cool and beat the summer heat, but did you know your air conditioning is a lot more than just a convenience – it is a safety feature in the midst of heavy heat waves.

Heat Is More than Just Uncomfortable

We tend to think of heat as this massive, uncomfortable inconvenience. In reality, it is quite dangerous. According to the Center for Disease Control, heat waves killed 8,015 people between 1979-2003, more than hurricanes, tornadoes, lightning, earthquakes and floods combined in that time period.

Why is heat illness so dangerous? It comes on quickly and it’s easy to ignore the warning signs, especially when you are already uncomfortable. While hydration is important, the real risk occurs after you’ve become dehydrated – when your body can no longer keep itself cool. This is known as heat stroke and can lead to a number of life threatening conditions, especially for the elderly, infants and those with chronic conditions.

That’s where air conditioning comes in. On the CDC’s extreme heat preparedness webpage, air conditioning is listed as the number one preventative factor against heat related illness. Simply put – if you have an air conditioner, there is a much smaller chance you will get sick from the heat. Dehydration happens less frequently when you’re in an air conditioned environment, meaning that your body can regulate temperature internally and you feel comfortable – not a bad deal for a simple installation.

Staying Cool Is a Medical Necessity

Heat is more than just a direct threat. It addles the mind and makes your reaction times slower. In effect, by allowing your body to overheat, you put yourself at risk. Simple tasks like climbing a ladder or taking out the trash could result in an injury because you don’t have the energy or the mental clarity to perform them as you would on a normal day.

So, air conditioning is about a lot more than just staying comfortable – it’s a health issue. Especially if you have small children or elderly adults in the house or if anyone in your family has a medical condition like obesity, heart disease, mental illness, poor circulation, an air conditioning system is an absolute must during heat waves.

For more information about keeping your house cool, contact your local air conditioning contractors.
