How Does Ductless Heating Work?

Thursday, February 5th, 2015

Ductless heating systems used to be favored almost exclusively by apartment complexes and small businesses. Areas that did not need warm air to be transported further than one or two rooms. It wouldn’t make sense to install central heating in such areas, so ductless heaters were used as an alternative. This is by no means the only use for ductless heaters, however. Recently, homeowners have been installing ductless heating as their main method for heating their homes. While it may seem counter-intuitive, ductless heating actually has quite a lot to offer a homeowner interested in installing a new home heating system. Let’s examine how ductless heating works, and how it can benefit you.

Ductless Heating Construction

A ductless heating system is constructed of two units, one installed inside the room and one installed outside of the house. These two units are connected by refrigerant and power lines. The inside unit is often mounted on a wall or the ceiling of the room that it is meant to heat, while the outside unit is installed on an exterior wall of the house. A thermostat can be installed in the room to control the system.

Benefits

Ductless heating works like a heat pump, moving heat from one place to another instead of combusting fuel to create it. When the heat is turned on, the outside unit will siphon thermal energy from the air and into its refrigerant coil. It then sends the charged refrigerant to the unit inside the room, which releases the thermal energy into the air to heat it.

The primary reason that homeowners install ductless heating systems is the level of versatility that they provide. The lack of ducts means that each room will need to have its own ductless heating system. Though this may seem expensive and needlessly complicated, it grants the ability to set a different climate for each room. This is something that a centralized heating system is not capable of doing. Ductless heating systems also avoid the nearly 30% of heat lost on average to duct leaks that central systems have to deal with. Thus, ductless systems both save energy and provide added options compared to other heating systems.

How Does Incorrect Duct Size Affect Your Heating?

Friday, January 30th, 2015

Ducts are a vitally important, and all-to-rarely considered, part of your forced air heating system. Though they are naturally unobtrusive and often quiet, ducts require just as much consideration during installation as any other part of your heating system. If the ducts are improperly sized during installation, it can have an enormous negative impact on your heating system’s ability to operate. Let’s examine the consequences of installing ducts that are either too large or too small.

Oversized Ducts

Each forced air heating system is equipped with an air handler, which is designed to move a certain volume of air a set distance. This volume changes depending on the size of the system. The different options for duct sizing are meant to match the different sizes of heating systems and their air handlers, so that the proper amount of air is circulated around the house.

By choosing ducts that are too large, you are providing a lot more area for the air handler to cover. As the system itself is not rated to move air that distance, much less air will actually make it into the various rooms that need to be heated. This leads to a dramatic loss in heat output for the heating system, which is a waste of money for you.

Undersized Ducts

Ducts that are too small for your heating system will result in an increase in static pressure. There are two consequences of this. The first is that your ducts will be much noisier than they should be. This should be easy to detect, as the noise is often so loud as to be extremely distracting. The second issue is that your system will have to work much, much harder to heat your home. The system will have to run longer and longer, to adequately heat your home, which will waste more and more money. Undersized ducts will also shorten your heater’s lifespan, as it won’t be getting enough air circulating through it to work properly.

Can a Ductless System Heat Enough?

Monday, January 5th, 2015

When using heat pump technology, as you will with a ductless heating system, there can be some concern that the heat pump may not be enough to sufficiently heat your home during very cold weather. This has to do with the way a heat pump works, which we’ll explain more about below. Heat pumps are great systems no matter what season you need them, and when it comes to heating, you can always supplement a heat pump with a back-up heating system. The experts at APC Plumbing & Heating have been helping Denver residents with their heating needs since 1984 and we can help you, too. Have concerns about using a heat pump during winter? Let’s take a look at how they work.

How Heat Pumps Works

Heat pumps work by transferring heat from one location to another. They do this with the help of refrigerant. During the winter months, heat pumps absorb heat from the surrounding air, concentrate it, then disperse it to your living spaces; heat pumps can use ducted or ductless systems to do this. The concern during the winter months come when the air temperature drops below 32 degrees for an extended period of time. This is because the available heat in the air decreases, and can force your heat pump to work harder to achieve the heating you need. We certainly see our fair share of cold temperatures during the winter, so one of the best ways to maintain your indoor heat is to augment your heat pump with a back-up heating system.

Working With a Back-Up Heating System

When you use a back-up heating system with your heat pump, the heat pump remains your main source of heating, but can switch to a back-up source of heating, such as a gas furnace, during the colder days of winter. This allows you to have the benefits of a heat pump system while ensuring that you have the heat you want on the coldest days.

A heat pump can be sufficient for your heating but if you have concerns, speak to your APC Plumbing & Heating expert about the installation of a back-up heating system. We offer professional heating services throughout Denver.

Is it Time to Replace My Heater?

Friday, November 28th, 2014

This is a pretty common question among homeowners who have had their heaters for a decade or more, and it’s a good thing to ask. There are a number of different things we could point to in different systems that would indicate the need to replace your heater. In the interest of keeping things simple, however, we’re going to cover the three factors that every homeowner should consider regardless of what kind of heater he or she has.

Increase in Heating Bills

Now, you can always expect a slight variance in your heating bill from month to month. You don’t use your heater the exact same amount of time each month, after all. It’s when you start experiencing consistent increases that you should be concerned. As a heater gets older, wear and tear begins to build up on the various parts of the system. This will eventually cause the parts to break, but before that happens they will slowly lose efficiency. This will cause your system to have to work harder to achieve the same results, which will lead to the increased heating bill.

Increase in Repair Frequency

A consequence of the aforementioned wear and tear, the various parts in your heater will wear out until they eventually break. Different parts wear down at different rates, which will stagger the effect a little. However, there will come a point where it seems like you have to call a repair technician every couple of months. At that point, it is very likely that your heater has reached the end of its lifespan. Once this happens, it tends to be much cheaper to replace your heater entirely than to keep paying to replace individual parts.

Age

One of the easiest things to measure, the age of your heating system serves as a good indicator of whether or not to replace it. The rule of thumb is: if your system is over 15 years old, it might be time to consider replacing it. If it is under 15 years old, ask a professional if it is viable to keep it for a few more years.

If you think you need to replace your heater, call APC Plumbing & Heating. Our HVAC technicians provide professional heating services in the Denver area.

Why It’s Important to Correctly Size Your Heating System

Friday, October 31st, 2014

When you first go shopping for a home heating system, one of the first things you’ll likely notice is that there are many different sizes of heating units. At first, you may be tempted to buy and install the largest unit you can find. Larger units generate more heat, which is better for your home, right? Well, yes and no. Yes, a larger unit can generate a lot more heat. However, this is not always the best option for your home. Read on for an explanation of why it’s important to correctly size your heating system.

Short-Cycling

When your heating unit turns on and off rapidly throughout the day, that’s called short cycling. This is one of the most common side effects of installing an oversized heating unit. When a heating unit that is too big for your home is turned on, it very quickly exceeds the recommended heat output for your home. This leads the system to think that the central unit is overheating, which trips a safety feature and shuts the heater down. A short time later, the unit restarts and the whole thing starts over again.

Long periods of short-cycling are not only annoying, but damaging to several parts of your heating system. The constant stopping and starting causes vastly increased wear and tear on the burners and heat exchanger. This severely shortens the life of your system, as well as increasing the likelihood of major problems like a cracked heat exchanger.

Expense

Installing an oversized heater in your home is much like trying to outfit a car with a jet engine: they’re just not designed to work together. Along with problems like short-cycling, an oversized unit will burn more fuel and breakdown more frequently over time. This will lead to more expense, both in terms of higher heating bills and increased repair costs. The heater will also be less efficient at actually heating, due to its irregular heating cycle.

If you aren’t sure what the optimal size is for a home heating system, call APC Plumbing & Heating. We provide professional heating services throughout Denver.
