Why Do I Need an Indoor and Outdoor Unit for Heat Pump Installation?

Friday, January 2nd, 2015

At first glance, the components involved in heat pump installation may seem a bit odd. The indoor heating unit fits right in, occupying much the same spot as any other central heating system. The outdoor unit, however, can be installed as far as 100 feet away from the house. It can be difficult to understand why that outdoor unit is necessary, as it certainly doesn’t seem to be helping to heat the home from that far away. Once you understand how a heat pump works, however, it all makes sense. Let’s examine the heat pump system, and why it needs both units.

Heat Pump Construction

As you may or may not know, a heat pump is not a combustion-based heating system. Unlike furnaces and boilers, which largely burn fuel to create heat, a heat pump merely moves heat from one place to another. This is part of what makes heat pumps so energy efficient. They only need electricity to operate, and consume no other fuel to work.

The way that a heat pump moves heat involves the indoor and outdoor units working together. Though they can be installed quite far apart, the two units are connected by a conduit that contains power and refrigerant lines. The refrigerant line is connected to a coil in each unit, which is vital to the operation of the entire system.

When the heat is turned on, the outdoor unit begins to evaporate the refrigerant in its coil. This turns the gaseous refrigerant into a heat sink, drawing thermal energy out of the air around the unit and into the coil. The refrigerant gas then carries that heat to the indoor unit, which converts the refrigerant back into a liquid. This process releases the heat, which is used to warm the air in the home.

So you see, the outdoor unit is the unit that actually provides the heat to your home. Without it, the heat pump would be a fan and not much else.

How Does Heat Pump Installation Differ From a Central Air System?

Friday, May 16th, 2014

You may have heard the term heat pump used in conjunction with home heating and air conditioning, and you may have wondered what exactly it entails. A heat pump is no different from an air conditioner in most respects, save one. A normal central air conditioner generates hot air as well as cool air: that air is vented outside your home while the air conditioner is running. A heat pump uses that hot air to warm your home in the winter the same way it cools the home in the summer. Here in land O’ Lakes, heat pump installation can be performed by the same services that provide air conditioning repair. How does heat pump installation differ from a central air system? That depends.

In some cases, a heat pump can be installed in the same place your old central system was located. The technician simply fits the heat pump to the existing duct system and ensures that the various lines and vents are clear. In many ways, this is the ideal situation for installing a new heat pump, since it doesn’t involve any radical changes to your house. In other situations, you may need to retrofit your ducts and air handlers to handle the new system, which requires a little more work.

In cases where you don’t want to use a centralized systems, heat pumps can be installed as ductless mini split units. In these cases, your duct system is rendered inert and multiple individual heat pumps are placed in the various rooms throughout your house. This requires opening line connections between indoor and outdoor components, ensuring electrical connections are secure and similar installation steps. It may not be the right choice for your home, but if you lack the space for a centralized system it could be just what you need.

We work throughout Land ‘O Lakes, heat pump installation is part of our core service and we can discuss your options with you to determine the best choice for your home. Pick up the phone and give us a call today!

Heat Pump Guide: Benefits of Installing a New Heat Pump

Monday, October 22nd, 2012

If operating your Land O’ Lakes home’s heating or air conditioning system causes you concern about utility costs or environmental impact you may want to consider the installation of a new heat pump. Heat pumps offer you the ability to both heat and cool your home in an efficient, eco-friendly way. Here is some basic information about heat pumps from the Land O’ Lakes heating and air conditioning professionals at Ierna’s Heating and Cooling.

How a Heat Pump Works

Heat pumps work on the principle of heat transfer. This means that, rather than consume a fuel to create energy, they absorb ambient heat from the air, water or ground surrounding your home for use inside. Only a small amount of electricity is used in the heat transfer process, meaning that energy use is greatly reduced and utility bills along with it. The process is easily reversed, too, so you can use your heat pump to transfer heat outdoors from your home when temperatures are high.

Types of Heat Pumps

There are few different types of heat pumps. Air-source heat pumps absorb heat from the air for use in your home or transferal out of your home. Water source heat pumps take energy from or return it to the ground or water on your property. There are a number of factors to take into consideration before having any type of heat pump installed on your property. Not all types of heat pump installations may be available in your area, so be sure to do your research before deciding which is right for you.

Offset Purchase and Installation Costs

An air source heat pump installation from a qualified service provider such as Ierna’s Heating and Cooling  is a great choice for many homes. It all comes down to efficiency. A high-efficiency furnace will cost more than a lower efficiency model, and the same is true of home comfort systems in general. The fact of the matter is that you can offset the initial costs of your heat pump heating and cooling system by reducing energy consumption.

When you’re ready to start exploring your heat pump options, call the professionals at Ierna’s Heating and Cooling. We’ll help you decide if a heat pump is right for your Land O’ Lakes home.

HVAC Question: What is a Heat Pump Reversing Valve?

Monday, July 23rd, 2012

Did you know that heat pumps can be used for both heating and cooling in your Tampa home? The reversing valve is what makes this possible, read on to learn more!

In General

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.
