Home Heating Guide

All homes feature different heating systems—some of them are more efficient than others. As time passes more advancements are made in home heating, allowing us to heat a space efficiently while making as small an impact on natural resources as possible. Regardless of what heating system your home uses, there are ways to maximize efficiency. And if you’re in the market for a home heating system upgrade, the following information will help you choose what direction to take.

Here is a quick sampling of heating methods, old and new, available in today’s homes.

1. Fireplace

The oldest method of heating devised by humans, the hearth fire is mesmerizing and warms both the heart and the body. However, its disadvantages can be considerable. It uses trees as fuel and contributes to air pollution. It is also fairly inefficient at heating large spaces and can be hazardous if regular cleaning is put off for an extended period of time.

2. Pellet or wood burning stove

As an improvement on the fireplace, stoves can burn pelletized wood scraps or smaller pieces of wood and generate more heat. Pellet stoves produce an insignificant amount of air pollution, and the fuel is made from wood waste created by the lumber industry. A stove can heat a large room, but it’s still relatively ineffective at heating an entire house worth of space.

3. Central heating

Central heating generally involves either gas-burning or electric furnace. Colder air is pulled in thru a return vent to be heated by the furnace, filtered and then distributed thru a ducting system thru the entire home. Central heating keeps all rooms evenly warm, but related utility bills can be high depending on usage and fuel type. The furnace and ducts must be checked and maintained regularly. Newer central heating furnaces can have efficiencies of up to 98% and are far quieter than older 80% models.

4. Space heaters

Space heaters are small, portable heaters designed to heat a small area such as a bedroom, bathroom, or office. They can be electric, propane, or kerosene-fueled. They are an excellent option for occasional use in a space that can’t be efficiently heated any other way, but they can be costly to operate; especially if they are of the electric variety.

5. Solar heating

Solar power generators use energy from the sun to either create electricity, which is then used to power traditional central heating, or heat water, which may be used to operate a radiant heating system. Although sometimes expensive to install and not practical in all areas, solar power has the potential to drastically cut a household’s utility costs if managed well.

6. Radiant heating

Radiant heating, often used in conjunction with other methods, circulates hot water in pipes built into the flooring of a home. It is an excellent choice for bathrooms and bedrooms, providing gentle warmth rather than the high temperatures of space heaters or central heating. Radiant heating can be expensive to install and may not be a practical addition to older buildings, but it can lower the monthly heating bill in some building configurations.

7. Heat pumps

Heat pumps are a popular method in milder climates like San Diego’s. These come in several varieties: air-source pumps use electricity to transfer heat between the house and the outdoor air; geothermal pumps pull heat from underground sources and can work well even in very cold climates; and absorption heat pumps can be powered by several heat sources, including natural gas, wood, and coal. Because this is a relatively new technology that requires installation of pipes underground or into walls, the initial cost can be high, but the day-to-day operating costs are very low—even when the primary energy source is electricity. Some heat pumps use a variable-speed compressor to reduce wear on the unit and save energy. Many homeowners use ductless mini-split heat pumps to create zones of different temperatures in their house, further increasing energy efficiency.

The best heating method for any home will depend on several factors, including climate, subsoil, how the house was built, and how the home is used.

Stay Safe, Stay Warm

There are a lot of different ways to heat your home in the wintertime, and all of them can lead to fire and other safety hazards when the proper precautions aren’t taken. These precautions include learning the correct operation and maintenance best practices for each type of heating used in your home, as well as an gaining an understanding of the common hazards associated with those heating sources—and how to prevent them.

Many homes have more than one type of heating installed, and homeowners often supplement those sources with space heaters and other forms of localized heat. Here we’ve discussed the most common types of home heating, the hazards associated with each, and maintenance tips for optimal performance and safety.

But first, some basic precautions that every homeowner should take:

• Learn the system. Become more familiar with your heating system so you know when it’s working properly and when it’s not. Learn how to perform basic maintenance on your system to keep it running at optimal efficiency to prevent fire and other safety hazards.
• Schedule detector tests. It only takes a few minutes each month to check all the smoke and carbon monoxide detectors in your home. Hold a detector test at the same time of every month and show each member of your household how to check them. Keep extra batteries on hand so the ones that stop working can be replaced immediately. Carbon monoxide dangers are associated with all types of combustible heating, including fireplaces and wood stoves, so consider installing one in your home even if you don’t have gas or oil heat.
• Install fire extinguishers. Keep a fire extinguisher on each level of the home in an easy-to-access location and in places where a fire is more likely to occur, such as the kitchen.
• Create and practice an evacuation plan. Every home should have a fire and emergency evacuation plan and it should be practiced on a regular basis to keep it fresh in everyone’s minds. Make sure you hold fire drills at different times of the year during both the day and night.

Gas Furnaces/Central Heating

Gas heating burns fuel and produces carbon monoxide as a by-product. Carbon monoxide detectors warn us about leaks, but regular cleaning, filter replacement, and professional inspections will keep the system running at top efficiency and safety so that leaks never happen in the first place.

Carbon monoxide sinks, so install detectors low to the ground. Be cautious of installing combined carbon monoxide and smoke detectors too close to the ceiling, or use separate units for optimal safety. Carbon monoxide poisoning will often affect children and pets before adults. Unusual lethargy and sleepiness are two of the first signs to look for.

To avoid fire hazards with central heating, replace filters once a month during daily-use months and have your ducts inspected regularly for leaks. Leaky ducts cause systems to work harder and run longer, increasing the risk of fire. Vacuum in and around the entire unit twice a year to remove dust and flammable debris. Keep intake and output registers clean and clear from furniture, debris, and flammable materials.

Woodstoves and Fireplaces

Burning wood for heat is common but comes with a number of special fire hazards and precautions. Have your chimney inspected and cleaned once a year. Do not use excessive amounts of paper or any liquid flammables to start a fire, as hot, roaring fires can cause a chimney fire. It’s more efficient to keep a smaller, sustained fire anyway. Remember, there’s an art to starting a fire—it’s not just igniting a pile of fuel. Keep your woodpile dry and away from your home’s perimeter. Don’t decorate your hearth and mantel with flammable materials and plant debris.

When burning wood in a fireplace, keep a protective screen around the opening to keep sparks and embers contained. Keep flammable materials well away from the fireplace, hearth, and mantel. Keep a fire extinguisher within arm’s reach of the fireplace, and do not leave a fireplace fire unattended.

Woodstoves should be double checked for proper installation and correct clearance from combustible surfaces. Wood stoves should be burned hot for 15-30 minutes a day to prevent creosote buildup in the stove and chimney.

Woodstoves and fireplaces should be cleaned regularly and ashes should be disposed of properly. Scoop ashes into a metal bucket with an inch of water in the bottom. Wet ashes can be added to a compost pile or applied directly to a garden or other outdoor plants. Do not dispose of ashes indoors or keep ash containers indoors.

Space Heaters

Space heaters are available in many shapes, sizes, and designs these days, and they are often electric. Standalone oil-burning units can also be used but require proper ventilation. Portable units should come with an emergency shutoff in case the unit tips over.

Choose a space heater that suits the space you’re trying to heat, for optimal performance, energy use, and safety. Keep space heaters in a safe area away from children, pets, furniture, and flammable household items.

Stay warm this winter, and remember to put safety first. Contact an HVAC professional like Bob Jenson Air Conditioning and Heating if you need help preparing your home’s heating system for the coming months.

As the weather shifts to cold and rainy here in San Diego, it’s time to start thinking how to get ready for it. Before you turn on your furnace, central heating or even light your fire place, take a look at our helpful checklist:

Get your home prepped for winter

Winter is coming, and even in temperate San Diego, we have to prepare. The weather cools down, we experience storms and wet weather, the trees lose their leaves. We crank up the heat, break out the blankets and coats, and make hot tea a regular evening ritual.

Did you know your home needs some special attention during the colder months too? Winterizing your home is an important part of keeping it in good shape, and the best time to do it is now. See 5 home winterizing tips described below.

1. Clean your windows.

It’s not the most fun job, but washing your windows works two-fold to keep your home warm and comfortable for winter. First, cleaning the dust, dirt, and grime off your windows offers unobstructed light. More sunlight entering your home means more natural warmth and illumination. A good wash also gives you the opportunity to check for cracks in the glass, damaged caulking, and any other punctures in the window’s surrounding structure. Cracks and holes let in drafts and allow warm air to seep out of your home.

While some homeowners will hire professional window cleaners, you can do it yourself quite easily. Purchase a commercial window cleaner or make your own by mixing a quarter cup of white vinegar with a gallon of water. If you don’t have a soft cloth on hand, wipe your windows using newspaper, which is absorbent but won’t leave lint (wear gloves if you do this—the ink does bleed).

2. Get your furnace/heating system inspected.

Your heater is your main line of defense against the winter cold, so it’s a good idea to do the important maintenance now, while the weather’s still nice. Call an HVAC professional like Bob Jenson Air Conditioning and Heating to take a look at your heater. A professional can oil the bearings, check the fan belt, remove any dust and debris—both of which can significantly decrease your heater’s efficiency—and make sure that everything is in working order.

One thing that you can do without professional help is checking and replacing the filter. A dirty filter prevents the heater from operating efficiently, forcing it to work harder and leading to a bigger dent in your wallet. You should replace the filter once a month for best results.

3. Insulate.

Insulation keeps the warmth in and the cold out, so make sure that all parts of your home are properly insulated. One of the most ignored parts of the home is the attic. As heat naturally rises, you need to make sure your attic has plenty of insulation. Otherwise, all that precious warmth will just rise up and out of your home. Experts recommend about a 12-inch depth of insulation in your attic. There are several different types of insulation to choose from, so contact HVAC experts like Bob Jenson if you need help selecting an insulation that works best for your budget.

If you live in the mountainous regions of San Diego like Pine Valley or Julian (but last winter we had freezing temperatures countywide), you should consider insulating your pipes as well. Frozen water will cause the pipes to burst, warp, or otherwise prevent them from delivering water to and from your home. Most hardware stores offer foam insulation tubes that are affordable and fairly easy to secure to your outdoor pipes.

4. Clean out your gutters.

Okay, San Diego sees maybe seven days of rain in the entire year, but you still have to be prepared. Even a small storm can cause water damage to your roof, walls, and foundation. Gutters are designed to move the moisture away from your home to prevent leaks and damage, but that’s assuming they’re not clogged up with dead leaves and dirt.

Scoop out any debris in your gutters then flush them out with a spray from your garden hose. Patch up any cracks and repair other damages. Your gutters should fit snug against your home, not hanging loose and crooked.

5. Reverse your ceiling fan.

Turning on your ceiling fan is probably the farthest thing from your mind when you’re shivering under a blanket. Hark! Your ceiling fan is actually more helpful than you think. See, most ceiling fans have a reverse function that allows the blades to move clockwise. As mentioned earlier, heat naturally rises, so it tends to hover closer to the ceiling than down at the carpet. The reverse motion of the fans forces the warm air around your ceiling back down while drawing the cold air up and away. The constant movement also keeps the air from feeling stagnant.

Make sure you and your home stay warm and cozy this winter with these tips and you won’t have to worry about winter utility bills that are harsher than Jack Frost.
