Moving right along to longevity:

  • a conventional hot water heater lasts approximately 8-10 years
  • a tankless hot water heater lasts approximately 25-30 years

And on to speed and efficiency:

  • a conventional hot water heater may take awhile for the water to heat up
  • a tankless water heater heats water on demand
  • a conventional hot water heater wastes hot water when you run the faucet
  • a tankless water heater can provide unlimited hot water
  • a tankless water heater is up to 34% more efficient than a conventional hot water heater because it heats water as you need it

And finally on to cost:

  • a tankless hot water heater saves you at least $100/year over a conventional hot water heater

Water Heater Wednesday: Tankless Water Heaters

Water Heater Wednesday: Tankless Water Heaters

Last week on Water Heater Wednesday we talked about the benefits of tankless water heaters and how they can save you money. Today we’re going to talk about selecting a tankless water heater.

There are several things to consider when thinking about purchasing a tankless water heater for your home- fuel type,  demand, and purpose.

Fuel Type

Tankless water heaters can be electric or gas. If you’re going to purchase an electric tankless water heater, you have to consider voltage, amperage, and your circuit breaker.

  • Voltage- Most units sold will accomodate 110V, 208V, 220V, and 277V.
  • Amperage- Different units will have different requirements. Make sure you can support the electrical demands of the unit you choose.
  • Circuit breaker- Make sure you have a circuit that will support an electric water heater. You may have to put your water heater on its own circuit.

If you’re going to purchase a gas tankless water heater , there are also a couple of things to consider.

  • Gas type- You need to determine if your gas type is natural or propane. Make sure you have thoroughly checked out your current gas line to determine whether or not it meets the requirements of the new water heater you plan on buying. The requirements of your new gas tankless water heater may exceed those of your old water heater.
  • Venting requirements- Venting is very important and these requirements should not be overlooked. Make sure to purchase Category III stainless stell (UL1738 certified) venting for your new gas tankless water heater. Type B venting accessories are not ok! Its also a good idea to check out your local building code for any specific needs. Some tankless water heater manufacturers sell gas venting kits. While these kits are handy, make sure you’ve checked out the specific installation requirements for the tankless unit you’ve purchased to ensure that kit will meet all your needs. There are many things to consider when installing a gas tankless water heater such as the vent route, where the discharge will go, access to air for combustion, etc.

Demand

When you’re choosing a tankless water heater, its a good idea to think about how many fixtures you’re trying to heat water for. Are you looking for a unit to heat water for just one sink? A whole bathroom? An apartment? A whole house? You may need to do some research on the typical flow rates for all the fixtures you are going to be heating water for.

Purpose

When shopping for a tankless water heater, you may have a specific purpose or need in mind. Here are some examples of the most common purposes and which model may work best.

  • Single Point Application- This is when only one fixture (one sink, one shower, a washing machine, etc.) will need to have water heated by the tankless water heater.
  • Thermostatic- A thermostatic tankless water heater boosts the temperature of the water if it has cooled off due to a long pipe run or for sanitation purposes. These units are great if precise temperature control is needed.
  • Whole House Use- Large tankless water heaters are designed to heat water for whole houses where many fixtures will need hot water.

Water Heater Wednesday: Tankless Water Heaters

Last week we talked about what a tankless water heater is and how it works. Today we’re going to discuss some benefits of tankless water heaters and how they can save you money.

Because of the way a tankless water heater works, it can be installed in a tight space, unlike a traditional water heater. This saves you a lot of space and is less of an eye sore. Also, since tankless water heaters deliver hot water on demand as opposed to storing hot water, they can save you a ton of energy. Another benefit is that they generally last twice as long as traditional water heaters as long as they are properly maintained.

Another great benefit of a tankless water heater is the amount of money you can save! Your up front cost for the purchase and installation can range anywhere from $2,000-$4,000. The price will depend on the size you need and which model you choose. Though initially this may sound like a lot of money, looking long term a tankless water heater will make up this cost and save you extra. Within two years, a tankless water heater will begin to pay for itself because of how energy efficient it is. The average home uses around 41 gallons or less of hot water each day. Based on this number, tankless water heaters can save you up to 34% more energy each day. A properly maintained tankless water heater can last more than 20 years….that’s a lot of savings!

Next week on Water Heater Wednesday we’ll talk about selecting the right tankless water heater for your home!

Water Heater Wednesday: Tankless Water Heaters

Tankless Water Heaters

 

This Wednesday we’re going to begin a mini series on tankless water heaters. Today we’re going to talk about what a tankless water heater is and how it works.

A tankless water heater provides hot water as it is needed instead of holding on to a bunch of hot water that isn’t needed (which costs you extra money). Its a similar concept to running the heat in your home during the winter- if you aren’t home you don’t run it. If you don’t need the hot water, don’t heat it up.

Tankless water heaters work by heating water directly as opposed to heating up a stored tank of water. When a hot water faucet is turned on in your home, cold water travels through a pipe into the water heater unit. Tankless water heaters can be electric (an electric element heats the water) or gas (a gas burner heats the water).

Tankless water heaters provide hot water at a rate of 2-5 gallons per minute. While this is a great rate, some tankless water haters can’t keep up with the demand for hot water in a large household. To circumvent this problem, you can install two or more tankless water heaters to keep up with demand. Since you’re not paying extra money to heat water that isn’t needed, the only additional cost to you is the initial cost of the water heater. You can also install tankless water heaters that are designated for certain appliances.

 

Next week, we’ll talk about more benefits of tankless water heaters and how they can save you money!

 

Quick Tips: How To Drain Your Hot Water Heater

Quick Tips: How To Drain Your Water Heater

Every homeowner should know how to drain a hot water heater. Over time, sediment can build up in the bottom of your tank which can cause problems. Draining your hot water heater is easy. Here’s a quick step-by-step guide on how to drain a water heater.

  1. Turn off the water supply- If its electric, turn off the power at the breaker box. If its gas, turn the thermostat to the pilot setting. Connect a drain hose to the valve near the thermostat and turn off the cold water supply.
  2. Drain the water- To prevent forming a vacuum, turn on one of the hot water faucets in your hosue (the tub, the sink, etc.). Open the drain valve on the hot water heater. Make sure the end of the hose that the hot water is draining out of is far away from anything that could be damaged by hot water.
  3. Get rid of any remaining sediment- Once all the hot water has drained out of the water heater, turn the cold water supply back on to flush out any sediment that remains in the hot water heater. Once all sediment has been washed out, close the drain valve and turn off the faucet inside your house. Make sure to read all the warning labels and instructions that go with your hot water heater- some hot water heaters need to remain full in order to prevent any damage.
  4. Check the pressure release valve- Turn your power supply back on once your tank has refilled. Once the temperature has come back up, check your pressure release valve by using the instructions that came with your hot water heater.
