Tag: tankless water heater

Water heaters are central to many of our daily tasks, from showering to washing dishes. But when they break down, it can be difficult to know what to do next.

If you’re experiencing hot water troubles, start by ensuring the circuit breaker or high-temperature cutoff isn’t tripped. Then, try relighting the pilot light (but only after following safety instructions). You can also drain the tank and flush it to remove sediment. Contact Water Heater Repair Tampa for professional help.

The heating elements on an electric water heater, especially older ones, can corrode over time and need to be replaced. When one or both of them go bad, you’ll experience insufficient hot water from the faucets. The water in the tank will also be dirty because it will contain sediment that has accumulated over time. Fortunately, the replacement process is simple and quick once you have the right tools.

Turn Off Power and Drain the Tank

First, turn off the water heater power by turning off the circuit breaker at the breaker box. Then, run a garden hose from the drain valve on the bottom of the water heater to a floor drain or bucket. Next, open the drain valve and drain the water from the tank.

Once the tank is empty, close the drain valve. Then, remove the access panels that cover the heating elements. Use a socket wrench to remove the old element. Be sure to use a non-contact circuit tester to ensure the element has no power before loosening the terminal screws and disconnecting the circuit wires.

The upper and lower heating elements are threaded in with a gasket behind the flange on the front of the tank. Most of the time, the lower element goes first, because it’s more exposed to sediment buildup. It’s also typically cheaper than the upper one, so it makes sense to buy two at the same time and cut down on future repair costs.

When installing the new element, coat both sides of the new gasket with pipe-joint compound. Slide the gasket over the new element and screw it in place. Be careful not to over-tighten, which can result in leaking and water damage. Once you’ve installed the new element, connect the black and white circuit wires to each of the terminal screws on the element. Once the element is secure, you can fold down the insulation and screw the access panel back in place over it. Reconnect the water supply valve and open a hot water faucet to start refilling the tank.

Thermostat Replacement

The thermostat on your car is responsible for regulating the amount of coolant that runs through your engine so it doesn’t overheat. If your radiator hoses are leaking fluid or the temperature gauge on your engine is constantly rising, it’s time to replace your thermostat.

The good news is that it’s pretty easy to do and you can save yourself the cost of a professional repair service by doing it yourself. Just make sure you turn off the power and water supply before you start. You’ll also want to have a bucket nearby to catch the fluid that will flow when you loosen the bolts holding the thermostat housing in place. Drain the old fluid into a clean two-gallon bucket and pour it back into your radiator when you’re finished.

Sometimes, your water heater will stop working exactly when you need it most. If you’re in the middle of a shower or washing dishes and it suddenly goes cold, that’s a sure sign that something is wrong with your heater. You can try a few things to troubleshoot the problem yourself, like checking if it’s a tripped breaker or blown fuse. If you’re unable to find the cause of the problem, it’s definitely time to call a plumber for more advanced troubleshooting.

It may be possible that your water heater is simply a little undersized for the size of your home or family, which could cause problems with rumbling or gurgling noises. If the problem isn’t caused by a mechanical issue, it might be best to upgrade your tank to a larger size.

If your water heater has a strange smell or discolored water coming out of the faucets, it’s likely a sign that it is rusting inside. This can be a serious health hazard, so you should contact a professional water heater repair company as soon as possible.

It’s a good idea to drain your tank on a regular basis to prevent sediment buildup. If you’re unsure how to do this, or would prefer not to deal with the hassle, you can always call Oliver for a hot water heater flush. We’ll figure out the problem and get it fixed fast.

Dip Tube Replacement

No matter your water heater’s age, a dip tube is important to a good supply of hot water. It’s a long plastic piece that fits into the cold water inlet of the tank and stops about eight inches above the bottom of the tank. The purpose of the dip tube is to keep cold water from entering the tank until the gas burner or primary electric heating element is able to heat it up. The dip tube also keeps cold water from mixing with the hot water coming out of your hot water heater. A faulty dip tube leads to lukewarm water from your faucets, and it may lead to rust in the bottom of the water heater.

A dip tube can be replaced as part of a Water Heater Repair. This is a relatively simple job that can be done at home with some common tools. The first step is to shut off the circuit breaker that supplies power to your water heater. Then, disconnect the cold water inlet valve. After the water heater is completely drained (you can help this along by opening a few hot water faucets in your house), you should be able to see a small amount of plastic flakes floating in the bottom of the tank.

You can then disconnect the drain valve on the bottom of the tank and connect a garden hose to it. Allow the tank to drain thoroughly, and you’ll be ready to replace the dip tube. Make sure that you use a dip tube that is made of cross-link polyethylene, as this is more durable than other types of plastic tubing. After the old dip tube is removed, simply insert the new one into the inlet and drain line connection and tighten it.

This is a relatively easy job for a homeowner, but you should always contact a professional when dealing with gas water heaters. There are real dangers associated with playing with a gas water heater without the proper knowledge, experience and equipment.

Pressure Valve Replacement

The pressure-relief valve is an often-overlooked but important safety feature on a water heater. It releases excess hot water when the pressure in the tank reaches dangerous levels, mitigating the potential of an explosion or a burst that can flood your home.

The PRV works by opening whenever the temperature or pressure in the water heater reaches its preset limit—usually 150 psi and 210 degrees Fahrenheit. It’s an important part of your home’s plumbing system, but like all parts, it will eventually wear out. If your PRV has worn springs, a gummed-up drain valve, or is experiencing corrosion, it will need to be replaced. The type of repair kit you need depends on the material your pipes and valve are made from, such as PVC, bronze, brass or copper.

In addition to checking the pressure-relief valve for damage, you should also test it periodically to ensure it’s functioning properly. Start by positioning a bucket underneath the valve to catch any released hot water. Then, while wearing safety goggles and rubber gloves to reduce scalding, turn the valve switch to the on position. If it’s working correctly, you should hear and see water gurgling from the drain pipe.

If you don’t have a water pressure reducing valve installed in your home, we recommend having one installed as soon as possible. Water pressure that is too high can cause appliance, faucet and fixture damage as well as waste energy. A PRV will prevent unnecessary strain on your plumbing system and eliminate that annoying screching sound you sometimes get with household appliances when using them.

Water Heater Denver is often located in the garage or basement. It is important to elevate them above the floor to reduce moisture, which can cause leaks and other problems. This also makes it easier to access for maintenance and inspections.

Water heaters use electric resistance heating elements to heat water. These are contained in a metal sheath and surrounded by insulation. When the element fails, it must be replaced.

The thermostat of a water heater regulates its temperature to prevent it from overheating. It also keeps the water hot enough to kill bacteria that could cause disease, such as Legionnaire’s disease. It’s recommended that the temperature be set to 120 degrees F. This helps prevent scalding accidents in younger children and the spread of dangerous bacteria that thrives in warm water.

The heating element in an electric tank water heater converts electricity into heat by passing it through a metal sheath that allows the current to pass but protects the elements from direct contact with water, thus minimizing corrosion and increasing its lifespan. The element is controlled by a thermostat and safety switch, which shut off the power supply if it exceeds a safe temperature.

Most gas and propane tank water heaters use an intermittent pilot together with an automatic flue damper or baffle blowers to help control their temperature. Because they are so efficient, these types of water heaters typically have energy factors of 67% or higher and meet ENERGY STAR standards.

A water heater that’s powered by natural gas or propane is also required to have a pressure relief valve in the plumbing line to prevent excessive, potentially explosive pressure buildup within the plumbing system. It’s important to have a properly installed pressure relief valve because it can save you time and money from having to replace broken pipes, water heaters and other appliances in your home.

Some newer tankless gas and propane water heaters have an integrated temperature control. However, since these units are located closer to the point of use, they can be subject to temperature fluctuations from varying flow conditions. This is why a downstream ASSE 1017/1070 temperature-actuated mixing valve is still recommended for these applications.

The temperature controls on tank-style gas and electric water heaters use relay outputs (also called solid state relay drivers) to energize the coil of a larger heating contactor that’s used to turn on and off a large amount of heating power. The temperature controllers also have hysteresis bands to help maintain accurate temperatures, and they can test for a broken output device such as a heating element.

Safety Features

Thermostats, heating elements and safety switches are built into State water heaters to ensure that they don’t overheat. A thermostat controls temperature and a safety switch monitors water temperatures and shuts off the electricity to the element if it goes above a safe limit. This feature protects against scalding accidents and electrical problems.

Another safety feature is the venting system that directs gas fumes out of your home. This helps prevent carbon monoxide build-up, which is a dangerous and deadly gas that may leak from a broken or malfunctioning water heater. Inadequate or faulty venting can cause fumes to go back into your house, so it’s important to keep the vents clear and free of dips or drafts.

If you have a gas water heater, it’s also important to elevate the unit at least 18” from the floor in a garage or area where gasoline containers or vehicles are stored. This will minimize the risk of combustion, which can occur if gasoline fumes come in contact with the pilot flame or any other combustible materials.

While not as common, fires can also be triggered by combustible objects like canisters of gas, garbage or clothing that are kept near the water heater. This is especially a concern for gas water heaters, which operate with an open flame. Fires can also be triggered by a tripped high-limit switch, which is another safety feature built into State water heaters.

When you hire a plumber for installation and maintenance of your water heater, make sure that they’re certified and understand the proper safety precautions. This is especially important if you have gas connections, which should only be handled by certified technicians to avoid gas leaks and other dangers. Additionally, when working on electrical wiring, always disconnect the power to the unit and use a circuit tester to verify that it’s off before touching any wires. It’s also a good idea to keep a fire extinguisher nearby, in case of an emergency.

Energy Efficiency

The old days of bulky, inefficient water heaters are fading into history, thanks to advancements in energy efficiency and environmental sustainability. Today’s models are sleek and powerful, and offer a range of features to save homeowners money on utility bills.

Traditional electric and gas storage water heaters use substantial amounts of energy, contributing to high utility bills and excessive carbon emissions. By comparison, demand or instantaneous water heaters use only the energy needed to heat incoming water as it flows through the system, resulting in lower operating costs and a smaller carbon footprint.

When selecting a new water heater, look for an ENERGY STAR model with an energy factor of 0.67 or higher, reflecting an estimated gas usage of 214 to 230 therms per year. In addition, ensure your water heater is properly sized to meet your household’s peak demands for hot water. Oversized units waste energy through excessive cycling and higher standby losses, while undersized units can cause problems with delivering sufficient hot water.

If you choose a natural gas tank water heater, look for one with a first hour rating of 82% or higher, reflecting the unit’s ability to deliver 82% of its total capacity in the first hour of operation. In addition, new standards for natural gas water heaters require that all units be tested using updated procedures to determine if they meet the new UEF rating, which takes into account the impact of tank size on efficiency stats.

On the other hand, a new generation of environmentally friendly heat pump water heaters (HPWH) uses free, renewable energy to heat your water. They don’t produce any direct emissions, and use as little as one-half to a third of the energy of conventional electric resistance and gas storage water heaters.

For eco-conscious homeowners, there are even solar-powered tankless and combination water heaters that generate electricity from sunlight, providing a sustainable solution to both space heating and domestic hot water needs. It’s important to note that, in many cases, solar water heaters cost more upfront than gas- or electricity-powered models, and the payback period varies by geographic location and local incentives. Additionally, acquiring rebates may require specific maintenance and monitoring and adherence to usage guidelines.

Maintenance

While a water heater may seem to be an innocuous appliance, it is actually one of the most complex appliances that your home or business will have. It has a number of safety features, such as the pressure relief valve, that help keep scalding water from spraying out of the unit and causing serious burn injuries.

It also has heating elements that are heated by electrical current to heat the water. If these elements get dirty or worn out, it can cause the appliance to work harder than usual to heat your water, which will result in higher energy bills for you. It is important to perform regular maintenance on your water heater to avoid any major problems.

Water heater maintenance typically involves checking the power supply, examining the heating elements for signs of damage and testing the thermostat and high-limit switch. While you can do some of these things yourself, it is a good idea to contact a professional to ensure that your water heater is properly maintained and functioning correctly.

The most common problem with electric water heaters is element burnout. This occurs when the resistance wire on the element becomes too hot, causing it to fail and require replacement. It can be caused by mineral buildup on the element, which insulates it and forces it to work harder than necessary, or by age. Performing regular element flushes can help prevent this from occurring.

Another common issue with electric water heaters is rust and sediment buildup on the bottom of the tank. Draining the water heater by connecting a garden hose to the spigot on the bottom of the tank can help eliminate this problem. It is best to drain about two or three gallons of water to fully flush the tank. This will help reduce the amount of sediment that builds up in the tank and shortens its life.

It is also a good idea to periodically check and replace the anode rod on the tank. This helps prevent the rust of the inside of the tank and extends the life of the water heater.
