Supercharge Your Water Heater - Add a Hot Water Pump For Faster Hot Water!

!: Supercharge Your Water Heater - Add a Hot Water Pump For Faster Hot Water!

Have you ever had to stand shivering in the cold morning air waiting for hot water with your arm outstretched, fingers extended into the cold stream of water. It seems to take forever for the water to get hot. Speed up it up with a circulating system.

Traditionally, if you had a circulating system, it meant that you had a hot water pipe that ran in a big loop from the outlet of the heater to each fixture one after the other, and then back to the inlet of the water heater through a small pump. By continuously pumping water through the loop you have instant hot water at every fixture.

This is very convenient. Hotels and motels have circulating systems; otherwise it could take hours to get hot water with such long pipes as they have.

However, instant hot water is also very expensive. Not only do you have to pay for the energy to run the pump continuously for long periods of time or even full time, but you also have to pay for the heat energy being radiated into the environment from that big loop of piping. The cost of heating the water is considerably more than the cost to run the pump.

There are a number of manufacturers producing circulating systems that utilize the cold water line as the return line.

Some of these pumping systems use small pumps that pump water very slowly, and are temperature controlled. The pump turns on when the water temperature drops below a set point, and then shuts off when the water temperature in the pipe reaches another set point. This keeps the water your entire piping system luke-warm . The water is warmer near the heater and colder the further you get from the heater, but it is tepid through out the piping system.

Most folks don't really want the cold pipe full of warm or tepid water. You don't get "Instant Hot Water" as the manufacturers claim. I think they should be honest and call them "Instant Tepid Water Systems". The Lang Auto-Circ and The Grundfos Comfort System are two such systems, and the Hot Water Lobster is another. The Hot Water Lobster doesn't have a pump, but relies on the fact that heated water rises, and the Lobster valve has to be substantially higher than the heater for the system to work.

Unfortunately these systems consume much more energy since you are heating that big loop of piping and return line and its surroundings. The cost of the energy will far outweigh any monetary savings from the water conservation aspect.

Another class of systems that use the cold water line as the return line is the "Hot Water Demand Systems". These systems only pump the water to the fixture when hot water is "demanded" by the user. The pumping costs are small; typically demand systems use less than .00 per year in electricity costs. This is because they run for such a brief time, typically less than 1 minute per use.

When the user turns on the pump it runs until hot water reaches the fixture and then the pump automatically shuts off. The cold water line does not end up full of warm water.

With the demand system the energy consumed is no more than if the user just ran the tap as normal. And since the water is not being circulated it does not affect the life of your tankless heater or the warranty.

The water is pumped more quickly than if you ran the faucet full throttle. You save time, water, energy, and money!

There are at least three manufacturers of demand systems, Metlund, RedyTemp, and Chilipepper. The Chilipepper will run any tankless water heater. Some models of the Metlund system will run tankless water heaters, and some won't, so be sure to inquire before you make a purchase.

Drains and the Discharge System

!: Drains and the Discharge System

Your myriad sinks are drained into the drainage or discharge system, which receives the liquid discharge created through the food and beverage preparation region. The first component of the discharge program is on the sink itself: the trap. It is really a curved section of pipe, where the lowest part of the pipe "traps" (or retains) some drinking water.

The trap is known as a P trap when the drain pipes go into the wall; it is known as an S trap when the drain pipes go into the ground. In addition to these traps, it's a great idea to have floor drains located directly beneath your larger sinks. The drains inside a commercial kitchen area should have a dome strainer (or sediment bucket), much like a perforated sink stopper that traps bits of dirt and food as liquids go down the drain.

For the heaviest-duty jobs, a ground drain having a a lot larger strainer compartment (called a sump) is suggested. The sump is at least eight inches square. Kind 304 stainless steel is the preferred material for drain fabrication, and coved corners make them easier to clean. Drains ought to not be flush using the ground, but recessed slightly (about 1/16 of an inch) to prompt water to flow toward them.

The drain pipe should be three to 4 inches in diameter, and its interior walls must be coated with acrylic or porcelain enamel that's both nonporous and acid resistant. A nonslip ground mat, with slats for drainage, ought to be a standard accessory beneath every sink.How many floor drains should you've in your kitchen? Let's count the locations in which drains are a must to catch spills, overflow, and dirty drinking water from ground cleaning:

1. Hot line region
2. Prep and pantry region
3. By the pot sinks
4. Dishwashing area
5. Dry
Storage region
6. Outside the walk-in refrigerator
7. Wait stations/service locations
8. Near steam equipment
9. Through the bar sinks
10. Under the ice maker

The ice maker has an additional unique drainage requirement: a recessed floor. One smart concept is to install several drains, inside a trench that's from a single to two feet wide and a number of feet long, covered having a rustproof metal grate. This is really efficient along the length of the hot line area or in the constantly wet dishroom.

When we talk about draining away waste materials, we're not just discussing water. The water often contains grease, and grease disposal is an enormous (and messy) problem in foodservice. A grease interceptor is needed by law in most towns and cities. It's commonly recognized as a grease trap, even though the professional plumbing industry discourages the use of this terminology.

Your area's building code will list which kitchen fixtures must be plumbed to the interceptor; usually, the water/waste output of the garbage disposal, dishwasher, and all sinks and ground drains must pass via the interceptor prior to it enters the sewer. Employee restrooms and on-premise laundry appliances generally do not have to become connected to the interceptor.

The role from the grease interceptor would be to prevent grease from leaving the restaurant's drainage program and clogging the city sewer system. Foodservice wastewater is really a large problem for sewers designed primarily for residential waste. Thus, fines and surcharges might be imposed on restaurants if their effluent (outflow) exceeds the local standards for its percentage of fats, oil and grease (FOG, in industry jargon).

As waste materials enters the interceptor, it separates into three layers: The heaviest particles of food and dirt sink towards the bottom; the middle layer is mostly water, with a little bit of suspended solids and grease in it; and the best layer is grease and oil. The interceptor "traps" the top and bottom layers whilst allowing the middle layer to flow away into the sewage system. Interceptors come in different sizes, and you ought to select a single based about the gallons of water that may run via it per minute, the number of appliances connected to it, and its capacity to retain grease.

Cleaning the interceptor regularly is necessary simply because the bottom layer can clog pipes if allowed to build up, and also the top layer can mix with, and pollute, the middle layer too much. Most restaurants hire a trap-cleaning service organization to handle this unpleasant task. It is really a costly activity, and not without legal ramifications. The support organization should be licensed to haul the grease waste to specially approved treatment areas.

It's not enough anymore for a restaurateur to trust that the grease is being taken care of. The smart ones take a proactive approach. Once in a whilst you'll see news reports about such support businesses that skirt the law by dumping waste materials into creeks or unapproved locations. You would be wise to thoroughly research your area's grease removal requirements and to interview a number of service businesses. Ask for, and contact, their references.

There are two kinds of interceptor cleaning: skimming (removing the best layer) and a full pump-out of the tank. For most foodservice operations, skimming isn't sufficient. The heavy, lower layer of particles must also be filtered away. You may decide on a combination of services-frequent skimming, with a full pump-out at normal intervals.

The types of foods you serve and your volume of business should be your guidelines, along with a scientific measurement of the effluent to see how much FOG and/or chemicals it contains. In some cities, the penalties are so strict that restaurateurs include a pretreatment step, adding fat-dissolving chemicals or filtering the waste materials prior to it even gets towards the grease trap. Undercounter units operate using electricity to recover grease for discarding as trash, not sewage.

Outside installation from the grease interceptor is suggested, at a level that is a number of feet below the kitchen area to use gravity in your favor in grease elimination. Constructing inspectors seldom permit an interceptor to become located anywhere inside the constructing, but if it happens to be within, it ought to be flush using the kitchen floor. Early in the building process, a call to your local plumbing inspector will supply the particulars for your city, and probably save you a lot of trouble.

We should also discuss the "dry" component of the discharge program, which is recognized as the venting system. Its main purpose is to avoid siphoning of water from the traps. Vents (known as "black vents") on both sides of the grease trap equalize the air pressure throughout the drainage program, circulating sufficient air to decrease pipe corrosion and help remove odors. Vent pipes extend up and via the roof, for kitchens and restrooms.

The auto circ pump is installed under the sink or faucet farthest from the water heater - where hot water usually takes the longest amount of time to arrive.

A built-in temperature sensor automatically turns the autocirc pump on when the water temperature in the hot water supply line cools down to 85º F. This cool water in the hot water supply line is then pumped into the cold water line and back into the water heater.

The autocirc pump turns off automatically when the hot water supply line to the faucet reaches a temperature of 95º F, ensuring the instant availability of shower warm water with maximum temperature hot water only seconds behind. When the pump is automatically turned off by the built-in thermostat, an auto closure device prevents hot or cold water from mixing in either supply line.

Another beneficial feature is that hot water will also be instantly available at all other faucets in the supply line between the water heater and the faucet where the autocirc pump is installed.
