Will You be in Hot Water in 2015?

You may be in 2015 since the Department of Energy’s new water heater efficiency rules go into effect on April 16^th, 2015. Most customers in this area have a gas fired hot water heater. A few have an electric hot water heater where natural gas is not available in their home. Both types will be affected. Check out our 99+ energy saving tips here.

A Side Note for Customer’s who had basements flooded

All manufactures strongly recommend you replace any water heater, furnace or boiler that has sustained flood water to any of the controls or moving parts. If the water level do not reach controls but did enter some part of the unit, there may be issues with mold. An immediate inspection by a qualified technician should be done.

New Gas Hot Water Heater Standards for 2015

Let’s first take a look at the new standards for gas hot water heaters since it will have the biggest effect on a home in the Metro Detroit area. These rules also apply to propane fired hot water heaters for those who do not have a natural gas option. The old rule stated that a gas-fired hot water heater between 20 gallons and 100 gallons of storage capacity must have an energy factor of .67. All residential heaters and residential units used in commercial applications have been meeting this standard for a number of years. The new rules breakdown those heaters into two classifications. The first classification is 20 to 55 gallon storage capacity and the other is over 55 to 100 gallon storage capacity. The 20 to 55 category efficiency has increased slightly from .67 to .675. This will have little if any effect on the average home with a 40 or 50 gallon hot water heater. On large homes, homeowners who have a whirlpool tub with a large capacity, or small commercial applications there is a major change in the energy factor. It moves from .67 to .8012. This will require a much more expensive tank with the need for an electrical circuit and a condensate drain. Standard residential tanks of 65 gallons to 100 gallons will no longer be available. Residential heaters used for commercial applications will be far more expensive and there may be issues with venting since a conventional flue pipe system will not work with the new tanks.

New Tankless Gas Water Heater Standards for 2015

You may be thinking I’ll just install one of those tankless water heaters and then I won’t have a problem. Well, there are changes with tankless water heaters also. The rules require all new tankless water heaters to have an energy factor of .82 which was raised from .62. These will also be more expensive for the unit and for installation. Dozens of energy saving tips here.

New Electric Hot Water Heater Standards for 2015

Now let’s check out the electric water heater changes. Once again the old standard for residential tank type water heaters was an energy factor of .97 for any residential electric tank with a storage capacity from 20 gallons to 120 gallons. The new standard breaks down the storage sizes to 20 to 55 gallons and over 55 to 120 gallons. The energy factor for the 20 to 55 gallon tanks actually drops from .97 to .96 energy factor. Really nothing will change for these sizes. But for tanks greater than 55 gallons of storage capacity the energy factor increased to 2.057. This will require a heat pump type of water heater or perhaps a solar powered water heater to meet these requirements. These are far more expensive than a standard tank type of electric water heater. The heat pump heaters may also create a noise issue since they have a compressor and fans in them.

Suggestions for Consumers

If your hot water heater is more than 8 years old, you should look into replacing it before the new standard takes effect April 16^th, 2015. Don’t wait too long because the supply of today’s standard tanks may be scarce as we approach the deadline for the changeover. You can also expect the price of those tanks without significant changes to go up to help manufacturers spread the cost of design, engineering, testing, and production of the higher efficient tanks.

Ouch! It’s Too Hot!

There is no easy answer to the how hot your water should be. It depends. It depends on the makeup of the family, the usage of the family, and safety for the family.

When I say safety, this is a two way street. If you look at the chart below, you can see it does not take a high temperature to cause burns especially for the elderly and the young. On the other hand water that is too cool can cause Legionnaire’s disease to form in the water. When a person is exposed to the vapor or water droplets the disease can form in their lungs as pneumonia. Each of these consequences are dire for a family. So what is the best option for the average family?

Let’s look at what the maximum temperature at a faucet where a child, an elderly individual or an adult may be scalded. These would be shower, bathtub, and combination bathtub/shower faucets. Very few faucets with separate hot and cold handles can be set for a maximum temperature so the solution for these would be to replace the faucet with a single handle faucet with a temperature limit built into it. The temperature limit must be set for each home since the incoming water temperature to the faucet can vary. The maximum temperature should be set below 120° F, preferably at 115° F. The faucet should also have at least a pressure balance feature. This feature reduces the flow of hot water when it senses a reduction of flow from the cold water supply. This could be caused by a toilet flush, a faucet turned on to cold, or a sprinkler operating.

Sinks do not require a maximum temperature on residential applications since higher temperatures may be desired and the thought is that a person could quickly remove their hands from the flow of water if it was extremely hot. In commercial application the code requires a maximum temperature of 120° F at sinks to protect handicap individuals. If you have a concern or a need to control the hot water temperature at a sink, there are controls which can be installed at individual sinks.

If you keep your water heater at 130° F or lower you are increasing the chances of Legionnaire’s Disease developing within the tank or piping. A water heater set at 120° F can have water inside of it as low as 100° F. The Department of Energy recommends 120° F set point but OSHA recommends 140° F to minimize the formation of the Legionnaire’s Disease bacteria.

Table of Hot Water Scalding Temperatures & Times
Water Temperature Setting	Exposure Time	Effects of Exposure to Hot water at These Temperatures
Water at 100°   F or below	See safety   note.	Most   water heaters are unlikely to scald an adult occupant;
Water at 120°   F	5 minutes	2nd & 3rd   degree burns on adult skin
Water at 130°   F	30 seconds	2nd & 3rd   degree burns on adult skin
Water at 140°   F	5 seconds	2nd & 3rd   degree burns on adult skin
Water at 150°   F	1 1/2 seconds	2nd & 3rd   degree burns on adult skin
Water at 160°   F	1/2 second	2nd & 3rd   degree burns on adult skin
Safety Note:   Hot Water Scald Burn Warning for Infants, Children, Elderly: great care must be taken when   exposing infants or children to warm or hot water as they can be badly burned   quickly and at shorter exposure times.
Source: A.O. Smith

Our recommendation is to set you tank at a temperature no higher than 140° F also be sure your shower and bathtub faucets are set at 115° F as the maximum temperature. This will provide reasonable protection from scalding and Legionnaire’s Disease. As stated above, if you still have concerns about sink faucet temperatures, a control can be added to the sinks in your home.

OH-Oh! No Hot Water!

We often receive calls from homeowners with gas hot water heaters who are without hot water. Like many appliances, your water heater will need occasional servicing to maintain peak performance. Sufficient air flow is crucial to the proper operation of your water heater. If the water heater is in a small tight area, a source air for combustion is needed. If the area around the water heater is large and a source for combustion air is available from the space, there may be other causes. The signs of restricted air for combustion are yellow flames, pilot outage, soot, unstable flame, or no hot water. Before starting any service or repair, consult the sections of your owner’s manual dealing with condensation, air requirements, gas supply, venting, and cleaning the air intake screen. Also, make sure that your heater is properly sized for your home. An undersized heater may result in condensation which can drip onto the flame causing a pilot outage.  Your water heater is built to the current industry safety standard and meets all FVIR (flammable vapor ignition resistant) requirements. This assures that any flammable vapors drawn into the combustion chamber and ignited cannot ignite remaining flammable vapors on the exterior of the heater causing a fire or explosion. This design includes a flame arrestor and one or two air intake screen(s). These screen(s) prevent larger particles of dust or lint from entering the heater, thus restricting air flow and causing improper combustion.  The owner’s manual asks you to visually check and clean the screen(s) as necessary.  Smaller particles may pass through these screens and lodge in the flame arrestor.

A second cause of many of these calls is a direct result of the hot water tank corroding and a leak developing in the tank. The appearance of water on the floor around the hot water heater is a visual symptom of a leak. It’s just time for a replacement.

Tankless heaters also require periodic maintenance. This includes deliming of the internal heat exchanger. This will be a more significant issue if you have a water supply with a high mineral content.

If you have an electric hot water heater, the answer could be a burned out heating element. There would not be water on the floor around the tank if an element has burned out.  There may also be a circuit breaker tripped or malfunctioning.

We are so used to just turning on the faucet and having hot water, that it’s a real surprise when the water flow is only cold. Most of these Issues require training and expertise to properly repair so be sure to call a professional. Our Technicians are factory trained to service all types of hot water heaters.
