Q.I am opening a quick service restaurant and need a new hot water heater. Very small - less than 1,200 sq. ft. mostly carry out. 40 seats max. Two rest rooms, 3 compartment sink and one hand sink in kitchen. No dishwasher. Health Department more interested in recovery gallon per hour. Must be 105 degrees min.
Is there a difference between commercial and residential in hot water heaters? Does Home Depot sell both?
A.50 gallon should be more than enough. most heaters are now energy efficient and quick recovery. Most home water heaters run at 120 degrees so that is not a problem. Unless you own the building, I would go with a tank since you will not be able to remove an expensive tankless if you move out.
1.00Are tankless water heaters really worth the investment?
Q.I'm needing to replace my hot water tank and was looking into the tankless water heaters? Has anyone used one and are you satisfied with the results?
A.Please read the following Consumer Reports article that states that while the tankless water heaters were 22 percent more efficient on average than gas-fired-storge-tanks but they are more expensive and could take up to 22 years to break even:

Personally, I really like them. In Japan, where they are very common, I used my tankless water heater every day to shower and to wash my dishes. It was excellent and I always had instant, plentiful, hot water available. I often wondered why we didn’t use these in the United States more often than we do. If you are interested I would recommend the following sites for some excellent models:

1.00Can anyone give me a recommendation on electric tankless water heaters.?
Q.I am specifically interested in the SETS and American Home brands and would like to know if anyone has them and how they do or do not like them. Also, I am interested in information on other brands if you have them. Thanks. I NEED THIS INFO ASAP AS OUR WATER HEATER BROKE THIS WEEKEND AND NEEDS IMMEDIATE REPLACEMENT.
A.Eemax is a widely used electric tankless water heater in the commercial industry. They are refered to as IWH or Instantaneous Water Heater.
However
1. If you are replacing an existing electrical instantaneous water eater, make sure the power and voltage match the existing one you are removing.
2. If you are working on your primary residence or a high hot water usage and you are trying to replace a tank style water heater - stop. Stay with the tank style. Really, only instantaneous gas water heaters are recommended for the primary residential environment.
1.00Does anyone know anything about tankless water heaters?
Q.Are they safe? Are they efficient? Do they save money? Is there anything you don't like about them?
A.As a builder, people are starting to request tankless water heaters moreoften, especially in more expensive homes. They are definitely safe, very efficient, which is why people want them because they save money. They cost more up-front but pay for themselves in the long run because they use less energy than traditional tank water heaters. The on-demand capacity of the heaters makes them especially friendly from an environmental perspective.
1.00Are tankless water heaters better for hard water areas?
Q.I live in an area with very hard water, and have had to replace two water heaters in 6 years due to sediment buildup. Would I be better off with a tankless water heater, or would that succumb to buildup, too? Thanks.
A.The prob is hardness in the water . Anything that heats water will collect minerals from the water on the heating surfaces that get hot. The only cure is to put in a water softner. But thay take a lot of mantainance also.
1.00How do I make it so my electric water heater heats the water in my new house?
Q.We just moved into our home, and it is not brand new, so we know this heater has worked in the past. Do electric heaters have pilot lights? I can hear some activity when the water is running upstairs, but no heating occurs.
A.Make sure the breakers on the main electrical panel are turned on. There is also an overload/reset breaker on most water heaters. Remove the cover and reset this as well. If it still doesn't heat, the electric coil or coils are probably defective. These can be purchased for about $20-$25 each at Home Depot. Some water heaters only have one - some have two. Good luck.
1.00Tankless water heaters, good or bad investment?
Q.Whats your opinion on the tankless water heaters?
Pros and cons?
A.Pros:
-They are much more energy efficient. You don't have a giant tank of water that is constantly being heated up. (think of all of the hours you are not using any water; sleeping, working, vacations.. and how much energy and money you now spend keeping water hot.)
-You never run out of hot water.
-You will save so much money in energy bills.
-If you go to sell your house, you will get your money back. People love new technology.
-They are much smaller and are wall mounted. This will free up space in your house.
Con:
-High initial cost, they are much more expensive than traditional heaters.
1.00How do Tankless Water Heaters work?
Q.I know they cost twice as much,are they worth the money.
A.Tankless heaters have a gas burner with a coil of water pipe above it. When you turn on the faucet, the water moves in the pipe and this movement is detected by a flow sensor, which turns on the burner. When the flow stops, the burner shuts down.
The device heats water in the pipe, on the way to the faucet.
The advantages are that they do not have to keep water hot that is being stored, and they take less space. They have different models depending on the capacity you need, just as tank heaters do. They do cost more, about $600 for the equivalent to a 30 gal unit. However they are less costly to operate. and properly installed they have a longer life.

Commercial Water heaters
Commercial water heaters are large scale industrial size water heaters that supply hot water to hotels, resorts, office buildings, industries and other commercial locations. In any commercial building, the water heater accounts for a big chunk of the total energy bill. In fact, n an average, a commercial water heater will take up to about 11% of the energy bill of the facility. This energy usage is markedly increased in the case of hotels and resorts, and other high use facilities where the percentage of the energy bill can be as high as 40%. Therefore, improving energy efficiency through an optimized commercial water heating system must be on top of every company's list.
The energy efficiency of commercial water heaters can differ based on the fuel type and the design of the water heating system. Typically, a commercial gas water heater has a thermal efficiency between 80% and 95%. In the case of commercial electric water heater, the energy efficiency depends on the amount of stand by heat loss. The lesser the standby heat loss the higher the energy efficiency. The design of the water heating system must also promote greater energy efficiency. For instance, buildings that have large peak water heating loads will need a storage system to store hot water. Large buildings also require pumps and valves to pump hot water throughout the facility.
A commercial tankless water heater is ideally suited for a building which has a more or less uniform requirement of hot water in a day. If the demand is greater at specified hours in the day, then a storage water heater works best. To find reputed commercial water heater installers or repair companies in Seattle, all you have to do is fill out the easy to fill form, and we will find reputed contractor matches for you.
