Commercial Water Heater & Residential Water Heater Questions & Answers

(Residential Questions below)

Q. Every time my water heater is heating, I hear a loud rumbling noise and popping sound. What is this and how do I get rid of it?

A. The loud rumbling and popping noise can be caused by the following:

1. Low water pressure: Normally the water pressure should be around 65-75 PSI. If your water pressure is low (35-50 PSI) you may hear a rumbling noise. Contact your water department for clarification on your water pressure and what it should be.

2. Sediment Build up: Sediment is caused by a mineral caused calcium carbonate.

When calcium is heated, the deposits fall into the bottom of the tank. This causes a rumbling noise when water sits between the sediment and the tank and turns into to steam bubbles. Sediment creates a barrier between the main burner and the water which causes more gas consumption (energy) to heat the water to the desired temperature. This also over heats the metal tank which over ea period of time can weaken the steel tank and damage the glass lining which will cause premature failure of the water heater. The hotter the desired water temperature the more calcium deposits fall into the tank.

Q. I have no hot water. How do I reset my water heater?

A. There are multiple ways to reset/relit your water depending on the model number of your water heater.

1. If you heater is an Electronic Ignition water heater then it requires an electrical supply of 120 volts. Simply unplug or interrupt the power to the water heater, wait about 10 seconds and reconnect the power supply to the water heater. After about 15 seconds you should hear a ticking noise. You can then look underneath the water heater to see if the main burner is on. If nothing happened then try to plug some other type of equipment into the outlet to see if there is power at the outlet. If there is no power try hooking an extension cord to the water heater to an outlet that has power to see if the water heater works. Call for service.

2. If you have a standing pilot water heater follow the instruction on the front of the water heater to relit the heater. If it does not work then call for service.

Q. What is the purpose of a recirculation pump?

A. The purpose of a recirculation pump is to get hot water within about 5 seconds to all faucets supplied by hot water. The recirculation pump is attached to a secondary supply line that is connected to the hot water supply line at the farthest fixture away from the water heater. The recirc pump then circulates the hot water thru out the entire building so every fixture has hot water within about 5 seconds of opening the faucet. A recirc pump and recirc line can save you on your energy bill because the pipes are constantly hot and you have warm water returning to the water heater.

Q. How long is my warranty?

A. All commercial grade water heaters have a manufacturer’s three year limited warranty. These water heaters consist of three years for tank leakage and one year for parts and labor. All water heater manufactures have an optional five year warranty at an additional cost.

Q. What type of maintenance can I do to my water heater?

A. Water Heater Man, Inc. offers a Preventative Maintenance Program for all water heaters and boilers. Please call for details.

Q. Can I down size my water heater to a smaller one for my property?

A. In some circumstances you can, but the job site would have to be properly sized with a water heater sizing guide. Most applications are sized to accommodate the usage of hot water at peak periods during the day. We don’t recommend downsizing your water heater unless all measures are followed and the application is sized properly. Please call for further assistance.

 


RESIDENTIAL GAS

Q. How do I know when I need a new water heater?

A. Unless your water heater is leaking, your water heater is repairable by a qualified technician at Water Heater Man, Inc. If your water heater is over 8 years old it is recommended to replace your water heater rather than to repair due to the costs affiliated with it.

Q. How long does a residential water heater last?

A. On an average the life expectancy of a residential water heater is about 8-10 years depending on the following circumstances:

1. Is there a water softener installed? If the answer is yes than the life expectancy of the water can be reduced. Water softeners are utilized for to reduce the hardness of the water coming into the water heater. The salt used in the water softener deteriorates the anode rod rapidly causing no protection for the water heater after about a year to two years.

2. “Thermal Expansion”. Thermal Expansion is created when the water in a tank heats up and expands. When water is heated it expands. When there are no faucets open to release the excessive pressure caused by the water being heated up, the T&P (temperature and pressure relief valve) will start to drip to release the excessive pressure. Thermal Expansion can be evident immediately upon a new installation or years in the future. If Thermal Expansion is present a properly sized expansion tank can be installed to cure this problem.

Q. What is an Anode Rod?

A. An Anode rod is a sacrificial rod made of either aluminum or magnesium. Residential water heaters will have one or two anode rods installed by the factory depending on the warranty the tank has when purchased. An anode rod is placed into a water to protect the tank from corrosion. The anode rod reacts to substances in the water and undergoes an electrochemical reaction and draws corrosion to itself rather than the glass lining of the water heater (tank).

Q. Should I flush out my water heater every six months to a year?

A. Sediment builds up in a water heater based on the hardness of your water. By opening the drain valve and flushing the heater will not drain the big particles or rocks of sediment. The opening in a drain valve is not big enough to let them pass through. We don’t recommend drain your heater. Once you open the drain valve sediment particles and get into the rubber seal and not allow the drain valve to close properly and your drain valve will be leaking until you call for service.

Q. My water is not hot enough when the weather gets colder?

A. When the weather gets colder the water temperature get colder. After using a large volume of hot water, it will take longer to heat up the cold water coming into the tank. Over night the water in your pipes cools off as the weather gets cooler. In the morning when running the hot water to take a shower, prior to the hot water getting to the shower the hot water has to heat the pipes as the cooler water is pushed out. You can give us a call and we can give you different options on saving water and getting hot water right away.
