The Importance of Water Heater Tune-Ups

The Importance of Water Heater Tune-UpsYour water heater works 24/7, 365 days a year to provide hot water whenever you need it. This demanding work schedule takes its toll on parts and expected service life. If you have noticed hot water issues, such as water discoloration, your water heater needs some TLC. Have you had a water heater tune up recently? Read on to learn why you should!

Why Tune Ups Are Important

Like your refrigerator, HVAC system and plumbing, your water heater provides an essential service to make life more comfortable and productive. Treat your water heater right, and it will pay off.

  • Energy efficiency: Water heating accounts for approximately 17 percent of the average home’s energy usage. When parts wear out or become overly dirty, you lose efficiency and energy dollars.
  • Safety: Water heater parts should be inspected each year to prevent safety issues regarding gas lines, burners, high pressure, water leaks and tank ruptures.
  • Avoid repairs: Regular service and parts replacement saves you an extra service call. Replace parts as manufacturer suggested during water heater tune up time, and save money and time.
  • Service life: Water heaters typically last anywhere from 8 to 15 years. That’s quite a gap. Take care of your appliance to get as many years out of it as possible. Catastrophic water heater failures and replacement are not cheap!

Water Heater Tune Up

Make home maintenance easy. Schedule water heater tune ups in the spring and fall when your A/C and furnace are serviced. Following are the basics of water heater TLC:

  • Inspection: Your technician inspects the flue to insure efficient flow of dangerous gases. Flex hoses and gas lines are inspected. The storage tank is checked for water leaks and rust.
  • Cleaning: The water heater is drained and cleaned to remove sediment.
  • Parts replacement: The anode rod, which is designed to rust instead of your steel water heater, should be replaced every 2 to 4 years.
  • Evaluation: You’ll receive an itemized list of services and the overall health of your water heater.

When You Should Schedule a Water Heater Tune-Up

When You Should Schedule a Water Heater Tune-UpThe centuries-old axiom, “an ounce of prevention is worth a pound of cure,” still rings true today when it comes to taking care of your home’s essential systems. Why wait for something to break down before you call a professional? It doesn’t make sense. What does make good sense is scheduling regular water heater tune ups in the spring or fall to keep your hot water flowing efficiently year-round.

Prevent Corrosion

Water heaters are susceptible to corrosion because they are manufactured of steel. To help prevent the storage tank from rusting, an aluminum or magnesium anode rod is installed. The aluminum and magnesium metals rust before the steel storage tank does.

Anode rods last about three to four years before they have corroded beyond the point of usefulness. So, it’s very important that your plumber replaces the anode rod every few years to prevent the storage tank from rusting and leaking water in your home.

Water Heating Efficiency

Water heaters warm up cold intake water with an electric heating element or a gas burner. Three common situations that occur with water heaters that reduce heating efficiency are:

  • The electric heating element or the combustion components age and falter.
  • The heating components become dirty and heat water less efficiently.
  • Sediment on the bottom of the storage tank inhibits efficient heating.

During annual preventive maintenance, your plumber drains the tank to remove deposits, cleans the combustion chamber, and inspects the heating element — saving you energy and helping your water heater last longer.

Schedule Pro Maintenance or DIY?

Modern home comfort systems, such as your water heater and HVAC systems, are sophisticated equipment that requires a knowledgeable pro to service. There are electrical parts to check, combustion parts to test and inspect, and much more.

As a homeowner, you can help maintain your storage tank between service visits by draining a gallon of water from the drain bib of the tank every few months. This helps keep sediment and deposits to a minimum.

Should You Invest in a Tankless Water Heater?

Should You Invest in a Tankless Water Heater?The most common reason most homeowners cite for choosing a tankless water heater is to save money on water heating costs and to save indoor space. As valid as these reasons are, there are other factors to consider before going ahead with a tankless upgrade.

How big is your family?

An average-sized tankless water heater won’t have trouble keeping up with a family of four, but if it’s larger, you may need to stagger bathing schedules or install a larger unit.

How’s the water pressure?

Homes with low water pressure might experience sudden drops in hot water volume, resulting in brief spurts of cold water while bathing. Before ruling out a tankless heater, ask a plumber to help you identify the cause of poor indoor water pressure and find solutions.

Is storage space at a premium?

  • Tankless water heaters use much less space than storage tank heaters. Depending on where you put it, you might be able to add storage or closet space.
  • Tankless systems are an alternative to a new storage tank heater that might require home modifications, especially if you need a large heater. New water heaters use more space because they require more tank insulation, need more venting, or are substantially taller.

How far away are the bathrooms from the water heater?

If the bathrooms are a distance from the water heater, you may want to install point-of-use heaters for the bathrooms. Not only will a separate tank deliver immediate hot water, it cuts water waste.

What kind of electrical service do you have or does gas run to your property?

A standard tankless system requires 200 amp service, but if you need a larger unit, you’ll need to upgrade the wiring to 300 amps, which will add to the installation costs. If you have natural gas running to your property, you can select this fuel for the water heater.

A tankless water heater uses less energy than a storage heater and may be the ideal choice for your home. For more expert advice, contact Roth Heating & Cooling, your plumbing experts for the greater Portland area.

Prevent Water Heater Damage This Winter

Prevent Water Heater Damage This WinterPortland winters can take a toll on your water heater, leaving you with cold showers and icy baths when temperatures plummet. The good news is that you can take steps now to lower the risk of water heater damage this winter. Keep the following prevention tips in mind to protect your water heater.

Flush Sediment From Your Water Heater

Sediment can build up inside your water heater as minerals accumulate in the bottom part of it. Over time, this sediment can make it more difficult for your water heater to work properly, since it needs more energy to heat your water. Have a technician inspect your water heater for sediment buildup and flush it as needed. This helps prevent you from running out of hot water this winter.

Insulate Your Water Heater

Just as you can insulate your pipes to stop them from freezing, you can also insulate your water heater to help save energy and protect it from damage. If you have an electric water heater, consider covering it with neoprene foam to insulate it this winter. For gas water heaters, you’ll most likely need to use fiberglass pipe insulation, along with aluminum foil tape to secure it. Insulation helps prevent water heater damage and also keeps the water in your heater warmer than usual. This reduces wear and tear on your water heater and lowers your energy usage.

Schedule an Inspection

Having your water heater checked for faulty parts helps lower your risk of losing hot water this winter. A technician can check your gas or electric water heater parts for any signs of damage and replace or repair them as needed.

Watch for Rusty Water

If the water coming out of your sinks and other fixtures has a rusty color, this can indicate a problem with your water heater. Have a technician check your water heater to determine if it needs to be fixed or replaced.

If your water heater needs maintenance or repairs this winter, please contact Roth Heating & Cooling. We offer dependable heating and cooling services for homeowners in the Portland area.

Benefits of Installing a Tankless Water Heater

Benefits of Installing a Tankless Water HeaterIf you’ve been thinking about switching to an on-demand or tankless water heater from a storage tank model, you might be put off by the heftier price tag and higher installation costs. To make an informed decision on which type is the right option, be sure to weigh the upfront costs against the following benefits you’ll gain from going tankless.

Prolonged Lifespan

On-demand units have the longest lifespan of all the different types of water heaters, providing an average of 20 years of reliable service. If you’re replacing a storage tank model with an expected lifespan of just 10–13 years, be sure to factor in these additional savings for a more accurate cost comparison.

Operating Cost Savings

Switching to a tankless water heater can reduce your household energy consumption and utility bills. Water is heated on demand, so the appliance doesn’t need to cycle continuously to maintain the temperature of 40 or 60 gallons of hot water. Over the years, this can add up to substantial savings that more than offset the higher initial cost.

Flexible Placement Choices

Tankless units are typically hung on a wall, and their compact size that’s comparable to a small suitcase provides a lot of flexibility in where they can be placed. The only constraints on the choice of location are the necessary connections to the gas and electrical lines.

Cleaner Hot Water

When you have a tank-type appliance, there are accumulations of sediment, scale and rust inside the tank, so the hot water that flows from your fixtures contains minute bits of all three. With an on-demand model, the water gets heated right in the piping, so it’s free from such particles.

Continuous Supply

Turning on a faucet or shower activates an on-demand heater, and it typically takes a few seconds for hot water to begin flowing. Once it does, there’s a limitless supply, so you won’t run out or have to wait for long periods while a tank full heats up.

During Cold Spells, Don’t Forget to Bundle Up Your Water Heater

During Cold Spells, Don't Forget to Bundle Up Your Water HeaterThe costs of water heating ranges from 14 to 20 percent of the average household’s energy budget. That’s plenty of incentive to keep your water heater in good working order — especially during cooler weather. Use these tips to keep a tight lid on your hot water bill this winter, help your system run better and to enjoy uninterrupted hot water service.

Signs of Wear

Take a look at the storage tank. Do you see any rust spots or water stains? These are signs of leaky gaskets. Ask your service provider to inspect the unit.

Another sign that your water heater needs professional maintenance is fluctuating hot water temperatures. Common causes for this are a failing heating element, sediment buildup inside the tank, a broken dip tube or faulty thermostat.

Temperature Check

If your water heater is heating up water greater than 120 degrees, you’re wasting energy. Use a thermometer to check hot water temperature at a faucet. Turn back the temperature dial a notch and wait a few hours before checking water temperature again.

Insulation

Inefficient water heaters lose more heat energy through the sides, top and bottom of the tank. This is called standby heat loss, and makes your system work harder — use more energy — to keep stored water at a consistent temperature. Insulation jackets and sleeves for the storage tank help reduce standby heat loss, reduce wear, and save you money.

You should also insulate the pipes at the storage tank, under sinks and at your clothes washer. Insulating pipe sleeves increase water temperature, reduce waiting time and save you money, too.

Drain the Tank

If you don’t flush out your storage tank once a year, you are flushing money down the drain. Mineral and sediment buildup inside the tank reduce heating efficiency and shorten the lifespan of your water heater. Your service provider should flush the tank during preventive service. However, you should drain a gallon of water at the temperature pressure and relief valve every couple of months.

Water Heater Sizing: Does Your Home Need More Than One?

Water Heater Sizing: Does Your Home Need More Than One?If you have a long wait between turning on your faucet or showerhead and getting hot water, you may think that there’s nothing you can do about it. It just takes as long as it takes, right?

The truth is, there is a solution that many homeowners aren’t aware of – installing multiple tankless water heaters near the points of demand is the solution.

What is a Point of Demand?

Any point where you need hot water to come out is called a point of demand. This includes your kitchen sink, washing machine, showers, and bathroom sinks.

How Does a Tankless Water Heater Work?

First, let’s think about a traditional water heater. With this type of water heater, water fills up a large tank. The water is heated up, then kept at the same hot temperature while it waits to be used. When you turn on a hot water tap, the water flows from the tank to your point of demand.

This system has pros and cons:

  • Pro: Stores a lot of hot water
  • Con: Uses energy to keep the water hot all the time
  • Con: Can be susceptible to rusting out and flooding your home

A tankless water heater is a much smaller unit that’s installed on a wall along the path of the pipe. When you turn on the hot water tap, water flows through the pipes and also through the tankless heater. Inside the tankless heater, the water is warmed up before it finishes its journey to your faucet.

Because tankless heaters are not as large as traditional models, it’s possible to place one near each main point of demand in your home. This allows hot water to get to your tap faster, reducing the wasted water that runs down your drain while you wait for it to heat up.

Additional Pros and Cons:

  • Pro: Requires less energy because they are not keeping water hot at all times
  • Pro: Avoids the “rusted out” problem of traditional models
  • Con: Higher initial investment

How to Understand Energy Star Guidelines

Lowering Bills with Lower Water Heater Temperature

How to Understand Energy Star GuidelinesFinding ways to save energy is on the minds of many homeowners these days. One area of your home that you may need to take a second look for savings is your water heater. After all, energy consumed for water heating in the average home is second only to the HVAC system. Use these tips and information for how and why you should lower your water heater temperature.

Lower Energy Bills and More

According to the U.S. Department of Energy (DOE), water heating accounts for approximately 18 percent of the energy consumed in the average home. By turning back your water heater’s factory temperature of approximately 140 degrees, or higher, to 120 degrees, you may expect to save 10 to 12 percent of water heating costs.

Additionally, water temperatures in excess of 140 degrees can cause scalding in a matter of seconds — especially in the very young, elderly, and physically or mentally impaired populations.

A lower water heater temperature reduces or slows corrosion and wear on your water heater and pipes, too. The higher the temperature, the faster that mineral deposits accumulate, which reduces efficiency and additionally increases energy bills.

Lower Your Water Heater Temperature

It may take a few tries and a few hours to adjust your water heater temperature just right. Here’s how to do it:

  • Use a thermometer to measure the temperature of hot water at the tap most distant from the water heater.
  • For gas models, turn back the thermostat dial located on the gas valve to the “low” setting.
  • For electric models, remove the bottom and top panels that cover the thermostats (some models have only one thermostat located on the bottom). Turn back the thermostat dial a few notches.
  • Give your water heater four hours for the temperature to fall.
  • Using your thermometer, measure hot water temperature again at the most distant tap.
  • Repeat as necessary until the temperature is at 120 degrees.

If you haven’t scheduled water heater maintenance in more than one year, contact Roth Heating & Cooling for an appointment, and we’ll take care of adjusting your water heater temperature for you!

Discolored Hot Water: Here’s What it Means

Discolored Hot Water: Here’s What it MeansTurning on a faucet in your home and seeing a flow of discolored hot water can be worrisome. There are several possible reasons why water discoloration occurs, and knowing how to identify the cause can help you decide whether you need to call a professional plumber.

  • Disturbances in the municipal supply — You can experience occasional water discoloration when fine sediment in the mains gets stirred up by hydrant use, routine maintenance, breaks or construction/repairs. Disturbed sediment normally settles within a few hours, and you’ll know this is the culprit if the flow from the faucet clears up on its own. To get rid of any remaining sediment, open all your faucets and let them run for several minutes.
  • Mineral sediment in the water heater — When water is heated, naturally-occurring minerals like calcium and magnesium form into scale particles that collect in your water heater tank over time. A severe sediment buildup not only discolors the hot water arriving at the faucets, it can block the gas burner or electric elements, reduce heating efficiency and eventually ruin the appliance. You can prevent these problems by draining and flushing the tank annually.
  • Decaying galvanized pipes — If you’re seeing orange or rust-colored water at both the hot and cold faucets and your home’s water pipes are galvanized steel, corrosion is the most likely cause. Galvanized pipes are protected on the outside by a zinc coating, so they deteriorate from the inside out. Before leaks start to occur, have your home’s water lines inspected by a licensed plumber to determine if they need replacement.
  • Water heater deterioration — If your cold water supply is clear, but the hot water flow has a brown or rusty tinge, the problem may originate in your water heater. If the appliance is more than 10 years old and you see evidence of rust on the exterior of the tank, there’s likely significant corrosion inside as well, and the unit should be replaced before it fails.

Here’s How to Know if You Need a New Water Heater

Here’s How to Know if You Need a New Water HeaterA reliable supply of hot water in your home is a necessity, so don’t wait until your water heater fails and you’re facing an emergency replacement. How can you tell if you need to invest in a new water heater? Pay attention to the following signs, then get the advice of a professional plumber.

Appliance Age

The average lifespan of a water heater is between six and 10 years. Exactly how long your heater lasts depends on whether its gas-fired or electric, its workload, whether it’s well-maintained and if you have hard water. If your heater is getting older, you can avoid the headaches of serious age-related problems by replacing it now.

Rust Development

If your water heater has started to deteriorate, you may see rust developing around the tank seams, the temperature and pressure (T&P) relief valve, the water supply lines, or the drain valve. If the hot water coming from your faucets has an orange or rust-colored tinge, the inside of the tank is starting to corrode.

Water Leaks

Even minor water leaks are a serious cause for concern, especially if they occur around the bottom of the tank. Replacing a leaking water heater promptly can let you avoid the mess of a sudden flood and the expense of water damage repairs.

Tank Noise

As water is heated, certain minerals it contains form into solid sediment that settles to the bottom of the water heater and causes popping and rumbling sounds inside the tank. Accumulating sediment gradually decreases your water heater’s energy efficiency, and will eventually cause it to fail.

Water Temperature Issues

Neglecting to flush your water heater to remove sediment allows it to build up and insulate the elements or burner. This makes it more difficult for the appliance to heat water to the temperature setting on the thermostat. If your hot water faucets are producing only a lukewarm flow, you have a serious sediment problem.

If you’re unsure whether it’s time to have a new water heater installed in your Portland home, contact us at Roth Heating & Cooling for expert advice.
