All water heaters that burn natural gas or propane require a venting system. The process of burning of the gas is called combustion and it creates heat, exhaust gases (including highly poisonous carbon monoxide), and moisture. The water heater's ventilation system removes these byproducts from the home, making it a critical safety feature. In most cases, the type of ventilation system depends on the type of water heater.

All water heater venting systems use a vent duct or pipealso called a chimney or flueto bring exhaust gases from the water heater to the outdoors. The duct may be metal or plastic, depending on the type of vent system. Water heater ducts may lead directly outdoors, or they may tie into a larger vent duct that also serves a gas or propane furnace or boiler in the home. This is called a common vent configuration. In many cases, the exhaust from the larger appliance heats up the common vent, improving the flow of the water heater vent.

In addition to venting, gas and propane water heaters need an air supply for combustion. This may come from the atmospheric air in the house, or it can come through a vent pipe that pulls air from the outdoors.

The most common problem associated with water heater venting is a condition called backdrafting, in which exhaust from the water heater fails to exit the home via the vent and instead ends up in the house. Backdrafting can have many causes, but it is most commonly due to poor vent design or installation and/or an imbalance of air volume in the home. The latter is often a result of ventilation fans, such as bathroom or kitchen vent fans, that pull air out of the house and create a vacuum effect that draws exhaust downward and into the home from the water heater vent.

Some water heater venting systems remove the possibility of backdrafting with fan-assisted ventilation or direct venting technology.

Standard water heatersthe most common typeuse atmospheric venting. The vent consists of a vertical or upward-sloping vent duct that typically ties into a common vent. The system works solely through natural convectionbased on the principle that hot air rises. Hot exhaust from the water heater naturally rises up through the vent and into the air outdoors, creating a draw that promotes this upward airflow. The power of the draw increases as the vent duct heats up.

Atmospheric vent systems work well (and without electricity) if they are properly designed and the home does not have backdraft issues. Poorly designed vents commonly have insufficient draw and/or are highly susceptible to backdrafting.

Water heaters with power ventingcome with an electric blower fan (often very quiet) installed on top of the water heater and can have either vertical or horizontal vent ducts. Since the vent does not rely on the buoyancy of hot air it can be run horizontally to the outside of the house. The blower cools the air so the vent can be runin PVC pipe(rather than metal, as is required with atmospheric venting) and is easy to assemble. The water heater must have a nearby electrical outlet for powering the fan.

With a direct-vent system, air for combustion is drawn from a vent pipe that runsthrough an exterior wall or the roof. Exhaust gasses are vented outdoors through a separate vent duct or through a separate chamber of the same pipe (this requires a double-wall vent duct). Direct-vent systems essentially "breathe" outdoor air, so they are not subject to the effects of backdrafting in the home. They also reduce the risk of accidental fires caused by flammable vapors around the water heater.

Water heaters in mobile homes are similar to those used in standard homes, but they must be designed for this application.Manufacturers often will not warrant a water heater if it is installed in amobile homeand is not specifically approved for that use. Standard atmospheric water heaters in mobile homes often require an outside access panel. If a water heater is located inside of a mobile home without outside access it is most likely a sealed-combustion unit with direct venting.

On average, water heaters last seven to ten years. Of course, this number is subject to many variables. Without maintenance and prompt plumbing repairs, a water heaters lifespan can be as short as four or five years.

I have had a lot of experience with these. There are several brands. I assume that you are going to use gas or propane, but there are electric models as well. Installation is not for the beginner. Gas piping usually takes special tools for threading, tests, and knowledge of what can go where and what cannot. Plumbing is the same, and there are locations that will not be approved for a water heater by code. Check with several licensed plumbers, see what brand that they use, and installed prices. Go for a direct-vent or sealed combustion type unit. They are much more efficient and eliminate additional holes being cut into the house. Rinnai is the brand that seems to have achieved the best reputation, but there are other brands out there. Check warranties and if the installer will do any warranty work without additional cost. Here's the upside: Endless hot water at a fuel-efficient rate, smaller footprint in your house. No tank constantly holding water. Here's the downside: Hot water diminishes in QUANTITY as opposed to reduction is heat, as with traditional water heaters. If you have several faucets on at once, the flow will be reduced, but the temperature will remain constant. They are expensive. Expect to pay up to five times or more the price of a tank water heater, but it MAY last twice as long. They are difficult to repair. You won't find parts at Home Depot, like you will for regular water heaters. I've seen hundreds go in and about half of the people are pleased, half say there is lifestyle adjustments to using them and they wouldn't do it again.

Tankless water heater install - possible DIY job? | Yahoo Answers

So I've been shopping for a new water heater for about 3 months... i really would like to order one ASAP. I've spent hours reading manuals, and just finished speaking with 2 different installer companies, the manufacturer and the vendor.. none of them would give me an answer. So here I am. I will be getting ALL of my work reviewed by a licensed installer before actually using the unit.

Current setup:

40 gallon natural gas water heater - flute moves over 30" then goes direct up in a dual walled flute through to the roof. This seems to be the normal way of doing it in my area.

Want:

relocating to corner of house (no chimney right now) 60 gallon gas water heater - direct vent - non powered unit will have flute move across about 36" and will have about 40" of rise. I want to vent out of the side of the house rather than putting in a new chimney.

Essentially the flute would go > straight out top of water heater > immediate 90 degree turn to horizontal> straight(ish) horizontal for 30ish inches > 90 degree turn to vertical (up to main level) > 90 degree turn to horizontal (out to the exterior of house) > 90 degree turn to vertical > vent cap on top

This is the unit I was looking at:

https://www.homedepot.ca/product/rheem-rheem-performance-platinum-60-gal-gas-water-heater-with-12-year-warranty/1000792889

I like dealing with home depot because my fam had one break at 11 years and they replaced it no problems.

I was comparing it to this unit here:

http://www.gsw-wh.com/en/products/direct-vent

this unit doesn't seem to have any issues with venting out the side, and I was wondering if I can essentially do the same thing with the rheem 60 gallon and a similiar 90 degree vent.

I'll add that non one in my area was really familiar with venting a NON powered water heater out of the side of the house, is there another issue I should be concerned about?

Forgot to add, I'm in Ottawa, ON - cold climate winter / hot humid summer.

My current water heater is 22 years old

Is this idea safe with the 60 gallon water heater?

Would this install (which also has an additional vertical + horizontal elbow) be safe with the GSW 50 gallon? (rather than manufacturer who shows it just venting straight out)

Water Heater Install - Vent out side of house - Safe?

Nationally, the average water heater repair cost ranges between $120 and $200, although prices can range up to $400 or more. Water heater repair costs will depend on the type of water heater you have (tankless, electric, natural gas, etc.), the source of the problem, the cost for new parts, and labor rates in your area. Common water heater issues include problems with the thermocouple, thermostat, heating element and leaks. Most standard electric water heaters have two thermostats and two elements. One example for the cost to replace a bad thermostat is $185 for parts and labor. Replacing both the thermostat and the heating element could cost approximately $150-$200. The thermocouple is a safety device that senses when the pilot light is burning and signals the gas valve to close if the pilot light goes out. If your thermocouple is bad or corroded, the average cost to clean and repair it could be between $350 and $400. If your water heater has started to leak, it is usually more cost-effective to invest in a new water heater than to repair it, unless youre covered by a warranty.

How much does it cost to install a tankless water heater?

Water heaters are an integral part of the plumbing systems in residential homes and commercial buildings. Increasingly, consumers are turning to tankless water heaters for their many benefits. These tankless models use heating elements that are placed in close proximity to where the water will be used. As opposed to a traditional tank storage water heater which uses a steady supply of electricity to store and constantly heat water, the tankless models only heat water as necessary.

The average cost for a propane poweredsingle-point tankless water heater system will be$1,500 - $2,000.

Tankless units can be installed on the interior or exterior of the building near the water use point and no more than 50 ft. from an adjacent power source (typically requiring 220 volts). This means that you will need a tankless heater for every water source. For example, if you have two bathrooms and a dishwasher, you will need three units, unless all three locations are fairly close to one another.

It's important to keep in mind the amount of water that can be heated via a tankless system (2 to 5 gallons per minute for a tankless unit, compared to the capacity of hot water in a traditional system). This is important when considering which system might be right for a building. For example, in a home with multiple people bathing, a washing machine running and perhaps a dishwasher running, all of these items cannot be used together off one unit. You must either install multiple units, or run one water source at a time.

For most single family homes, a whole house water heater will be sufficient, allowing you to have multiple bathers or a washing machine and dishwasher running at once. Both options should be considered to determine which is right for your needs.

Another important aspect to factor in is the expected lifespan of the unit. While traditional water heaters will typically have a lifespan of anywhere between ten and fifteen years, most tankless units can be expected to be in use for over twenty years.

While there are two main types of water heaters, as we've discussed, there are also varying methods for fueling them. The following table lists the costs for each type:

Once the type of unit and fuel have been selected, the plumber remove the old system, if existing, then a new gas line or heat source access and new water lines will be installed. This may include opening some walls or a ceiling, depending on where in your home the pipes run, and where you unit will be located. Ideally, you want the unit fairly close to where the hot water will be used in order to deliver the water in a timely way. Finally, the new tankless water heater is mounted and connected to the previously installed lines.

The average hourly rate for a plumber to complete the installation process is $45-$65, with installation running two to three hours for a total of $90 to $195 for labor alone. Additional costs include other materials needed for installation (heat pumps2, water pumps3, pipes, etc.) and the costs associated with permitting. These may add $250 to $500 to the final cost.

If walls need to be opened, you may need to also include the costs of drywall4 and finishing to the job, as much as $200. Most traditional water heaters sit in a closet for easy access; tankless models may need to have an access door added nearby in case of future issues to allow quick repair. This may need to be installed by a carpenter at a rate of $70 an hour, or a handyman at a rate of $100 to $300 for the project.

The average cost of a tankless water heater installed is around $1,500-$2,000. The cost of a gas-powered tankless water heater costs around $430 without installation.

Tankless water heaters are installed near the point of use, or place where the hot water is needed. A heating element heats the water as it passes through the heater, rather than continuously heating the water like a traditional tank.

Tankless water heaters heat approximately 2-5 gallons of water a minute, which is sufficient for most uses at each point. They typically last around 20 years - about 5 years longer than a traditional heater.

A tankless gas water heater lasts around 20 years, while a traditional gas water heater lasts about 15.

A tankless hot water heater is a heating element installed near the point of use. Water passes through the unit and is heated as needed, rather than continuously, saving on energy bills.

A new tankless water heater costs between $1,500 and $2,000 installed, while a whole house tank costs between $600 and $800. A tankless hot water heater costs around $430 without installation and a traditional heater costs around $440.
