High Bills? Time for a Water Heater Replacement or Maintenance

Signs include bad taste or smell in the water, cloudy water, and limescale on fixtures. You might also see stains on dishes and laundry, have plumbing problems, or suffer from health issues like water-borne illnesses or dry skin and hair.

‍

Tankless water heaters, also known as on-demand water heaters, heat water as it flows through a heat exchanger. They deliver hot water directly to your faucets or shower without storing it in a tank. Storage tank water heaters, on the other hand, have an insulated tank that holds 30-50 gallons of water. They heat and store the water until it's needed.

Water heater noises can come from sediment buildup, water hammer, loose parts, blocked valves, or electric heating element problems.

Common reasons for HVAC leaks include issues with the condensate pipe or pump. Other causes might be a clogged air filter, poorly insulated ductwork, or a boiler drain leak.

There are many types, like water softeners, reverse osmosis, mechanical filters, and absorption filters. These systems aim to remove certain contaminants and are often NSF certified for their effectiveness.

‍

On-demand (tankless) water heaters use less than 41 gallons of hot water daily. They offer 24 to 34 percent more energy efficiency than storage tank water heaters. If you use a lot of hot water, you might save an extra 8 to 14 percent. Installing a tankless water heater at each outlet can save you 27 to 50 percent in energy costs.

Popping or crackling sounds often mean there's sediment in the water heater. This sediment forms steam bubbles that burst as the water heats up.

HVAC leaks often stem from a clogged condensate pipe. Other causes include a faulty condensate pump, frozen evaporator coils, or a damaged drain pan.

Check your annual water quality report from the city for high contaminant levels. If you notice bad taste, smell, discoloration, or limescale buildup, your water quality is likely poor. You might need a filtration system.

‍

Tankless water heaters cost more upfront and installation can be complex and expensive. But, they last 20 to 30 years, twice as long as storage tank heaters. They can save homeowners over $100 a year on energy costs compared to gas-fired storage tank models. Electric tankless models save around $44 annually.

Banging or hammering sounds usually happen when water hits valves too fast, known as water hammer. Sediment buildup can also cause these sounds.

First, try to clear the drain line with a wet/dry vacuum. If that doesn't work, call an HVAC expert. They can use a specialized vacuum to clear the blockage.

Poor water quality can lead to illnesses like E. coli, Salmonella, Giardia, and Hepatitis A. It can also cause more general health issues, such as colds, flu, and nausea. Infants, pregnant women, and the elderly are at higher risk.

‍

Storage tank water heaters are cheaper to buy and operate more simply. This means less costly maintenance and repairs. They are easy and affordable to fix if they're not working right, unlike tankless models which are more complex and expensive to repair.

Whistling or high-pitched sounds come from water under pressure going through a small opening. This is often due to a valve not fully opening.

A broken or faulty condensate pump can cause water to build up and leak from the HVAC unit. An HVAC technician can test and replace a faulty pump.

For accurate water quality assessment, have it tested by a professional. Companies like EPA Water offer free testing. They will identify contaminants and their levels.

‍

Storage tank water heaters have higher utility bills because they constantly heat and reheat water. They take up more space and need to be replaced more often, after 10 to 15 years. This can be a challenge in small homes.

A hissing sound in an electric water heater means the lower heating element is covered in sediment. Flushing and draining the heater can fix this.

Look out for water pooling around the unit, dripping sounds, and a decrease in cooling performance. Fixing HVAC leaks quickly helps prevent further damage and keeps your system efficient.

Hard water signs include limescale buildup and reduced efficiency in appliances. A water softener can help solve these problems.

‍

Tankless water heaters are smaller and can fit in tight spaces or even on outside walls. They're ideal for homes with limited space. But, installing them can be complex and costly, especially when replacing an existing tank.

A humming noise usually means a loose heating element is causing the water to vibrate. Tightening the element should stop the humming.

Frozen coils can happen due to restricted airflow, low refrigerant, or dirty coils. When the ice melts, it can overflow the drain pan and cause leaks.

Bad smells, like rotten eggs or sewage, often come from high hydrogen sulfide gas levels. Installing a water treatment system can remove these odors and improve your water quality.

‍

Tankless water heaters provide continuous hot water but struggle with high demand, like multiple showers at once. Storage tank water heaters can handle high demand better but may leave the last person with a cold shower.

Vibrating or rumbling noises often come from sediment at the bottom of the tank. This trapped boiling water causes the bubbling and vibration.

A drain pan can wear out and develop cracks or holes, leading to leaks. If it's rusted, it might need replacing. For minor cracks, a water sealant solution might help.

Tankless water heaters are more complex and costly to maintain and repair than storage tank models. Storage tank heaters are simpler and cheaper to fix when problems arise. Both types need regular maintenance to work well and last long.

Listen to the noise type and try to find where it's coming from. This can help you figure out the cause, like sediment buildup or loose parts.

A clogged air filter can restrict airflow over the evaporator coils, causing them to freeze. This can lead to water overflow. Change your air filters every 1-3 months to avoid this.

Homeowners should think about the initial cost, energy efficiency, hot water needs, space, and maintenance and replacement costs. Tankless heaters are great for saving energy and space but may cost more upfront. Storage tank heaters are cheaper but use more energy and need replacing more often. A professional plumber can help you decide what's best for your home.

Call a professional plumber if the noises don't stop or you don't know the cause. Fixing it yourself could lead to water damage or injury.

Low refrigerant can cause the AC to cool poorly and make hissing or bubbling noises from the lines. An HVAC technician can check and recharge the system if needed.

Top water heater brands include Bosch, Navien, Noritz, Rheem, Rinnai, Tempra, and Trutankless. These brands offer both tankless and storage tank models for different needs and preferences. It's smart to compare their features, efficiency, and customer reviews to find the right one for your home.

Regular maintenance, like draining the tank and flushing the heater annually, can prevent noises. Using a water softener also helps.

Poor installation or a wrong setup of the condensate drain line can cause drainage issues and leaks. It's important to hire a skilled professional for installation and maintenance to avoid these problems.
