Water Heater Problems

When your water heater goes out, you’re natural instinct is to call your plumber to get it fixed right away and while this is an excellent idea, take a few minutes before making the call to see if there is a simple problem that you can fix without an expensive emergency plumbing service call for water heater repairs.

Water heaters are relatively simple devices, but there are several problems that can arise.  A standard water heater is just a large tank with a heating element that heats up the tankful of water and keeps it hot and available to satisfy a demand for hot water.

If your water heater has stopped heating water completely, check the pilot light (if you have a gas unit) to make sure the pilot light has not gone out.  If so, re-light it and see if that solves the problem.  If the pilot light goes out often, have it checked out by your plumber.

If you have an electric water heater, check the circuit breaker to see if it has been tripped.  Resetting the circuit breaker may solve the problem, but if the breaker trips frequently you need to have your plumber inspect the unit.

Low water temperature could be a result of an improperly set thermostat or the thermostat could be working improperly.  If re-setting the temperature doesn’t help, replacing the thermostat might do the trick.

Sediment build up in the tank can also cause heating problems and a reduction in the capacity of the tank.  Your water heater should be periodically drained and flushed to maximize efficiency and service life.  This can be a pretty big job so if you don’t want to tackle it yourself, have the tank drained and flushed by your plumber.

Water Heater Insulation Blankets

Up to 25% of the energy used in the average home is spent on heating water.  Most homes have storage-type water heaters that suffer from standby heat losses.  Storage type water heaters heat a tank of water and keep it hot until there is a demand for hot water for showers, dishwashing, laundry, or some other source.  Standby heat loss is the heat lost from a water heater when there is no demand for hot water.  The water in the hot water storage tank loses heat and the water has to cycle on to keep the water hot.

Standby heat loss can be reduced by up to 45% by adding insulation to the water heater.  Insulation blankets specifically designed for water heaters are available at your local home improvement center. Depending on the age and R-value of your water heater and the cost of installation (if any), a water heater insulation blanket will usually pay for itself in  A water heater insulation blanket can be safely installed by a homeowner on an electric water heater.  Installation of water heater insulation blankets on natural gas or propane water heaters is more complicated and should be completed by a professional plumber who handles water heater repair and installation.

Water heater insulation blankets are most effective on water heaters with a low R-value (below R-24).  If your water heater is warm to the touch, you should see some benefit from installing an insulation blanket.  In addition, water heaters installed in unheated space such as a garage, basement, or crawlspace will benefit from an insulation blanket more than water heaters installed in heated spaces.

Winter Water Heater Problems

Have you noticed that your water heater’s performance has not seemed as reliable during the cold winter months as it did last summer?  Maybe it takes longer for the shower to get hot or you run out of hot water sooner than you used to.

Whatever the symptoms are, many water heater problems first show up in the winter.   There are a few things you can do to help your water heater, but it may be a sign that you need to talk to your plumber about a new water heater installation.

If your water heater is located in an unheated space like a garage or basement, you may want to consider adding some insulation, caulking around windows, and weather stripping the doors to help those areas stay a little warmer.  Wrapping the water heater in a special water heater insulating blanket will also help reduce heat loss.

If your water heater is located some distance from your bathrooms and kitchen, you can help matters by insulating the hot water lines, especially if they run through unheated areas such as basements, crawlspaces, and attics.  You can wrap exposed hot water line with foam pipe insulation available at your local home improvement center.

If none of these suggestions do the trick, have your water heater checked out by a reputable local plumber.  You may have other issues such as a failing heating element, a broken dip tube, or an accumulation of rust and sediment in the tank.  Your plumber help you decide if it is time for a new water heater.

Water Heater Replacement

Most homeowners wait to replace their water heater until they have a hot water emergency.  Either the water heater quits working or worse, water starts leaking from the water heater.  For some reason, these water heater emergencies seem to happen at the worst possible time: when you are getting ready for work, at night, and on weekends and holidays.

You can avoid the added expense of an emergency plumbing visit and schedule the interruption in your hot water supply by scheduling your water heater replacement when it is convenient for you.  You can also avoid the damage that can be caused by a leaky water heater.  Most water heaters only last about 10 to 15 years before they rust through and start leaking so if your water heater is getting old, now might be a good time to call your plumber about installing a new water heater.

If you are replacing a conventional storage type water heater, keep in mind that you have other options such as a tankless or on-demand water heater.  There are advantages and disadvantages of each type so be sure to get as much information as you can before making a switch.

If you decide to stick with a storage type water heater, choose a size that fits your hot water usage pattern.  There is no need to move up to a larger water heater if you have not had any problems with running out of hot water.  In fact, choosing too large of a water heater not only wastes money on the appliance, but also wastes energy by needlessly keeping unused water hot.
