Why Is The Shower Water Not Hot Enough?

Problems of hot shower temperatures are prevalent irrespective of the type of shower you are using. Also, the problem could be with the shower or other parts making the hot water system.

Below are various reasons why your water is not getting warm enough.

1. Water Heater Related Issues

The hot water from your shower is a result of a water heater. Over time the water heater can develop issues that might result in the shower providing cold water. Below are some water heater related problems you should look out for:

a) Faulty Parts

A water heater is a complex machine with different parts and components, which must work in synch to ensure that you get hot water. If any of the components are not working, the shower will probably give you cold water.

For instance, if there is a buildup of dirt on the burner, the water heater will no longer generate enough heat to warm your water. Also, if the machine’s thermostat is damaged, you will never set the proper water temperature because it is inaccurate.

b) Leaking Water Heater

Leaking is another common problem with water heaters and results in the heater pouring water that is not warm enough.

Your water heater could be leaking because it is poorly maintained or due to the accumulation of dirt and debris that result in spring leaks.

Also, the water heater might be leaking because some of the parts are broken down or due to old age.

c) Wrong Sized Heater

The water from your shower might also not be hot because the hot water tank is not the right size for your house. To make the right decision on the correct size of water heater for your home, seek the services of a professional.

Also you shift to the tankless water heater. This way, you will get instant and on-demand hot water all through.

2. Pipe Related Issues

Water in your house runs through pipes, and the wrong setup or blockages along the lines could cause the water heater to malfunction. Below are some common pipe related issues that can make shower water not hot enough:

a) Cross Connected Pipes

Cross-connected pipes are used to allow for the flow of cold and hot water from the shower. This technology, however, was used back in the day before the invention of mixing valves.

Today, they are rendered obsolete after the invention of other technologies that make hot water easily accessible. However, if your house has cross-connected pipes, you cannot conclude right away that they are the cause of cold water from your showers.

Look at the other causes and go through the process of elimination and consult a plumber to make the final diagnosis.

b) Corroded Pipes

Corroded pipes reduce the flow of water, which affects the shower and general water flow around the house.

With reduced pressure, water will have a hard time reaching the water heater or flowing from the storage tank and, therefore, poorly heated water.

3. Mixing Valve Related Issues

The use of mixing valves is the technology that came to replace the cross-connected pipes. The valves are built inside the shower handle to ensure that the water does not get too hot or too cold water. However, the valves run into problems as discussed below:

a) Improperly Installed Valves

If the valves are not installed correctly, you will either get too hot or too cold water. The common installation mistake occurs when the valve is installed incorrectly, the top side down, or vice versa.

To get the right amount of hot water, ensure that the valve is installed in the proper position.

b) Clogged Valves

The valves are prone to clogging with continuous usage. To unclog a blocked valve, flush it with clear water. If you are still getting cold water after this, consider replacing the valves.

c) Valve Is Not Set Correctly

If the anti-scald valve is not set correctly, you will receive cold water from time to time. Therefore, check the calibrations on the valve and ensure that they are set at the right temperature.

To set it at the right temperature, turn it to the right and test the water until you get to the preferred temperature. The anti-scald valve is plastic part under the faucet cover.

d) Mixing Valve Is Not Working

The rubber parts of the mixing valve get worked up and damaged over time, which could be why your water is not hot enough.

Also, the rubber parts burn down, break, and cause blockages in the shower pipes due to the hot temperatures. In both cases, the mixing pipe should be replaced, and this should be left to a professional plumber for the best results.

e) Plumbing Crossover

The mixing valve ensures that cold and hot water mix in the right proportions to give comfortable hot water. However, in some instances, too much cold water mixes with the hot water, a malfunction known as plumbing crossover.

If this is happening in your pipes, you will never get hot showering water. The best you can get is lukewarm. Diagnosing the mixing valves for a plumbing crossover is complicated and can be solved by a professional plumber.

4. Other Causes

The causes highlighted above are directly related to the plumbing system. However, the water supply system and the shower can be working perfectly fine but still experience cold baths.

With that said, other possible reasons why your shower water is not hot enough include:

a) The Water Being Supplied To The Heater Is Too Cold

Sometimes the temperature of shower water is affected by the climate. If your water was warm enough in summer, and this changes during winter, it might be because the water is colder than usual.

Therefore if the issue is climate-related, adjust the thermostat to higher temperatures in winter and change it to standard settings when the sun is out.

b) High Demand Of Hot Water

If you live in a household with high demand for hot water, the water heater tank might not be able to supply enough. Therefore, you will be forced to shower before anyone else to enjoy the hot water.

c) Showering At The Wrong Time

Some water heaters adjust with time, and a change in your routine or schedule could see you showering with cold water. If you take your shower as the heater is switching off, the water will be cold. In that case, a change or adjustment in your routine will solve the cold water issue.

How To Make Your Shower Water Hotter

The solution to making your shower water hotter depends on the cause. Below are some possible solutions:

1. Fix Or Adjust The Thermostat

To get hot water, start by ensuring that the thermostat is at the correct setting. During colder months, adjust the thermostat to a higher temperature reading. Also, ensure that the thermostat reading is accurate and, if not, have it repaired.

2. Unclog And Replace Broken Parts Of The Heater

If your heater or water pipes are clogged, the only solution is to have them unclogged. This way, the water will be flowing at the correct pressure to you.

Also, if the valves or any other part of the heater is broken, you will need to replace them ASAP for you to enjoy hot water. Always contact a professional plumber for such repairs.

3. Upgrade Your Water Tank

If you have used your water tank for more than ten years, it might be too old to give you hot water, and it is best to get a replacement.

Also, if there is a high demand for hot water in your household, consider getting a bigger tank to meet the needs of everyone.

What’s more, you can switch to the tankless heating unit so that your shower water is heated on demand.
