Benefits of Installing a Tankless Water Heater

Benefits of Installing a Tankless Water HeaterIf you’ve been thinking about switching to an on-demand or tankless water heater from a storage tank model, you might be put off by the heftier price tag and higher installation costs. To make an informed decision on which type is the right option, be sure to weigh the upfront costs against the following benefits you’ll gain from going tankless.

Prolonged Lifespan

On-demand units have the longest lifespan of all the different types of water heaters, providing an average of 20 years of reliable service. If you’re replacing a storage tank model with an expected lifespan of just 10–13 years, be sure to factor in these additional savings for a more accurate cost comparison.

Operating Cost Savings

Switching to a tankless water heater can reduce your household energy consumption and utility bills. Water is heated on demand, so the appliance doesn’t need to cycle continuously to maintain the temperature of 40 or 60 gallons of hot water. Over the years, this can add up to substantial savings that more than offset the higher initial cost.

Flexible Placement Choices

Tankless units are typically hung on a wall, and their compact size that’s comparable to a small suitcase provides a lot of flexibility in where they can be placed. The only constraints on the choice of location are the necessary connections to the gas and electrical lines.

Cleaner Hot Water

When you have a tank-type appliance, there are accumulations of sediment, scale and rust inside the tank, so the hot water that flows from your fixtures contains minute bits of all three. With an on-demand model, the water gets heated right in the piping, so it’s free from such particles.

Continuous Supply

Turning on a faucet or shower activates an on-demand heater, and it typically takes a few seconds for hot water to begin flowing. Once it does, there’s a limitless supply, so you won’t run out or have to wait for long periods while a tank full heats up.

Water Heater Sizing: Does Your Home Need More Than One?

Water Heater Sizing: Does Your Home Need More Than One?If you have a long wait between turning on your faucet or showerhead and getting hot water, you may think that there’s nothing you can do about it. It just takes as long as it takes, right?

The truth is, there is a solution that many homeowners aren’t aware of – installing multiple tankless water heaters near the points of demand is the solution.

What is a Point of Demand?

Any point where you need hot water to come out is called a point of demand. This includes your kitchen sink, washing machine, showers, and bathroom sinks.

How Does a Tankless Water Heater Work?

First, let’s think about a traditional water heater. With this type of water heater, water fills up a large tank. The water is heated up, then kept at the same hot temperature while it waits to be used. When you turn on a hot water tap, the water flows from the tank to your point of demand.

This system has pros and cons:

  • Pro: Stores a lot of hot water
  • Con: Uses energy to keep the water hot all the time
  • Con: Can be susceptible to rusting out and flooding your home

A tankless water heater is a much smaller unit that’s installed on a wall along the path of the pipe. When you turn on the hot water tap, water flows through the pipes and also through the tankless heater. Inside the tankless heater, the water is warmed up before it finishes its journey to your faucet.

Because tankless heaters are not as large as traditional models, it’s possible to place one near each main point of demand in your home. This allows hot water to get to your tap faster, reducing the wasted water that runs down your drain while you wait for it to heat up.

Additional Pros and Cons:

  • Pro: Requires less energy because they are not keeping water hot at all times
  • Pro: Avoids the “rusted out” problem of traditional models
  • Con: Higher initial investment

What’s the Best Location to Put Your Tankless Water Heater?

What’s the Best Location to Put Your Tankless Water Heater?Where you put your tankless water heater affects how convenient and efficient it is to use. Finding the ideal location helps ensure you’ll have plenty of hot water even during the chilliest Portland winters.

Installing a Whole-House System

If you’re replacing a conventional storage tank water heater, the new tankless water heating system can usually be installed where the old system was. This is optimal because the gas and water pipes are already in place. In some cases, however, larger gas lines will have to be installed to meet the water heater’s demand.

The venting needs of a tankless system also affect its placement. If the system will be vented through the wall, the vent must be at least 3 feet from any operable window. If the system will be vented through the roof, you’ll need to make sure it’s possible to install a vent that’s long enough. For example, it may not be possible to place a large water heater in the basement of a two-story home and vent it through the roof.

Installing Point-of-Use Water Heaters

For a tankless system intended to supply only a few applications, the system is usually best placed as close as possible to the appliance or faucets it will supply. Keeping the water heater close ensures you’ll get hot water quickly and reduces the amount of heat lost from the water as it travels through the lines. That said, your home’s plumbing configuration and the location of the electrical panel also influence where you can install a tankless water heater.

For safety reasons, don’t place the water heater under pipes or air conditioning lines that could drip. Likewise, don’t put the water heater above an electrical box, which could catch fire if the water heater drips.

Get familiar with your local building codes as they pertain to water heaters. Systems installed on a second floor or in a finished attic may be subject to additional regulations.

The Ins and Outs of Tankless Water Heaters

Tankless water heaters are a great way to improve energy efficiency in your home. Traditional units heat and store hot water regardless of how much you use. This creates two problems: either you don’t have enough hot water, or you have too much and energy is wasted reheating the water. A tankless water heater solves both of those problems by providing hot water only when you need it.
