Types of Terminal Units Used with Boiler Installation

Friday, January 2nd, 2015

A boiler is a large unit often installed in the basement or in its own room or area for heating a home or business.

Boilers are quite effective at providing heat, as they distribute heat more evenly than forced-air units like furnaces and heat pumps and can be modified for zone control. Water is heated at the boiler and then makes its way through a series of pipes to allow convective and conductive heat into a room. But in order to do so, it must reach a terminal unit, which is selected by the homeowner and the technician during boiler installation.

Which type of terminal unit is chosen generally depends on your home and family’s needs and your budget. You should always speak with a technician before setting your sights on a particular type of terminal unit, but as a starting point, the following list contains a guide to a few of the most popular terminal units for hydronic heating systems.

  • Baseboard Units: A baseboard unit is installed at the bottom of the wall in each room or zone in the house. These units are highly effective and can blend into the décor of a room so there is little interference with the interior design. These are some of the most common terminal installations.
  • Radiators: A radiator is a fairly outdated terminal unit for heat transfer, but it’s still in use primarily in industrial settings, particularly where a steam boiler is in use. However, some homeowners appreciated the look and feel of cast-iron radiator, and keep it in the home for heating and to add an industrial or vintage feel to the home.
  • Fan Coil Units: A fan coil unit contains a heat exchanger, blower fan, and filter to circulate air in the home from a boiler and/or a commercial chiller. As water moves through the unit, it sprays onto the heat exchanger, allowing for a set of thermodynamic processes to take place so that a fan can blow conditioned air in the home.
  • Radiant Floor Heating: Finally, many homeowners today choose radiant floor heating, which means a set of pipes runs underneath the floorboards in order to provide even heating, warm feet, and all-around comfort.

Rust on Your Furnace: What It Means

Thursday, February 6th, 2014

At first glance, it seems like it couldn’t happen. Your furnace generates heat and it doesn’t use water to do it. So how can rust show up on an operating furnace? In point of fact, rusty furnaces are not entirely uncommon. If you have rust on your furnace, it helps to know what it means before you contact your local  McLean, VA furnace repair service.

Rust is caused by the intermingling of water, oxygen and metal in a process called oxidation. In order for that to happen, all three elements need to be involved. Furnaces use oxygen for the burning process and their metal components are self-evident. So the question becomes, how does water enter the system?

If your furnace is in a damp part of the house such as a basement, then water can creep in from an outside source: dripping from a leaking pipe, for example, or gathering from a breach in the wall. But that’s not the only place it can happen. The natural gases used to fuel the furnace can contain trace amounts of water vapor. When the gases burn, the toxic components separate from the rest of the gases in the heat exchanger and are vented safely out of your home.  This includes water vapor, but if the vapor cools before it exits the flue, it can condense and cause rust damage.

The effects can’t be seen right away and may take years to manifest, but when they arise, they are devastating. Rust will corrode and destroy the metal in your furnace, forcing you to replace the affected components at great cost. In the case of the heat exchangers, rust can create actively dangerous circumstances, since a broken heat exchanger could result in toxic gases being released into your home. If you spot rust on your furnace, call Polar Bear Air Conditioning & Heating Inc. to get it fixed. We can replace the rusty component as well as correcting the problems that created the rust n the first place. Give us a call today to set up your McLean, VA furnace repair service.

Important Air Conditioning Tips for Derecho and other Electrical Storms

Thursday, July 5th, 2012

On June 29, a devastating thunderstorm complex known as a derecho created a State of Emergency in the Washington DC area, producing widespread destruction and leaving more than one million people without power.  Although derechos do not frequently move through our area, severe thunderstorms are common in the summer.  Do you know how to protect your family, home and air conditioning unit?  Here are some simple tips that can save lives and thousands of dollars.

1. Turn off your air conditioning at the thermostat during a thunderstorm.

Electrical control panels in air conditioning systems can be easily knocked out by power surges caused by lightning strikes.  In other words, the lightning does not have to hit your unit directly to damage your unit.

This applies to other electrical equipment as well.  Televisions and computers are at risk if running during an electrical storm.

2.  Don’t take showers or baths during a thunderstorm.

 Electricity can travel through metal pipes into your bathroom.   It is also wise to avoid other sources of water with metal pipes, such as faucets and sinks, until the thunderstorm passes.

3.  Are cell phones safe in electrical storms?

 Electricity will travel through electrical cords and outlets, not radio waves.  So, cordless phones and cell phones are safe inside, as long as they are not plugged in to an electrical outlet.  There have been reports of lightning strikes to cell phone users and iPod users outdoors, not due to radio wave transmission, but because the users are holding a metal object, and that metal attracts and conducts electricity.  It’s best to put away your cell phone and iPod if you are caught outside in an electrical storm.

My HVAC System Has a 10 Year Warranty – Why Do I Need a Maintenance Agreement?

Wednesday, July 13th, 2011

While every new system sold comes with a limited warranty for the unit and parts, it is a good idea to supplement your warranty with a more complete maintenance agreement with your HVAC provider. Why pay for a secondary maintenance plan when you already have a warranty?

For the most part, the limited warranty provided by the manufacturer is meant to cover things like faulty parts, abnormal breakdowns or recalls. However, systems need regular maintenance, such as cleaning and replacing filters, cleaning condensate drains and traps, and if that is neglected, it won’t be covered by your manufacturer’s warranty. Neglected equipment wastes energy, and in extreme cases, can become unsafe to operate.

Help Your System Last Longer

Another benefit of a maintenance agreement for your HVAC system is that the system lasts longer when it is regularly maintained.  Neglected equipment breaks down more often and requires replacement sooner than properly maintained equipment.  Check out our maintenance programs page to read the inspections and services performed in regular checkups.  This service will help your HVAC system last significantly longer than if you were forced to wait until you could afford an extra visit from your repair man.

Imagine how much money you’ll save if your furnace or air conditioner lasts for 20+ years instead of just 10. Any breakdowns after the 10 year mark would require hefty repairs or replacement since your warranty is expired. So, it’s in your best interest to keep your system running smoothly throughout its lifespan.

Ultimately, an HVAC system is only as good as what you put into it. If you’re careful about your investments and are willing to spend a little extra now, you’ll stand to benefit far more in the future from a smoothly operating, efficient heating system.
