Water Heater Sizing: Does Your Home Need Multiple?

Water Heater Sizing: Does Your Home Need Multiple?When the time comes to replace a water heater or look at water heater placement in new construction or renovations, it’s worth asking the question: “Should we install more than one?”

With new construction, you have more choice about where you place your water heaters. When you’re just replacing your existing model or working with your old floor plan on renovations, your options may be more limited, especially when you’re considering traditional “storage” model water heaters.

Storage models are the old-fashioned water heaters that come with a tank. With this model, you have to dedicate a specific amount of floor space to the water heater. It functions by filling the tank with water and warming it to the set temperature. The water heater continues to keep the stored water warm until it is needed. Then the water travels from the water heater’s location to the point of demand.

Problems With the Traditional Model

There are a few disadvantages to this setup. One of the biggest problems is that any point of demand that’s far away from your water heater results in a wait before you get hot water.

Another issue is capacity. Your water tank can only hold so much hot water. Once it’s used up, you have to wait to get more.

Solutions That Fit Your Home

Tankless water heaters were invented to solve the problems with traditional storage models. Some advantages of the tankless model include:

  1. Installs in different locations. Tankless water heaters are compact and can be placed almost anywhere along a water pipe’s route. They attach to the wall, freeing up floor space. In fact, they can go in attics and crawlways if needed.
  2. Proximity. Since you have more options on installation location, you can place tankless water heaters near your home’s points of demand, reducing wait time.
  3. Energy savings. Tankless heaters “heat as you go” instead of maintaining gallons of heated water for long periods of time. This saves money on your energy bill.

Your Tankless Water Heater Doesn’t Heat as Fast — What’s Going On?

Your Tankless Water Heater Doesn't Heat as Fast -- What's Going On?Tankless water heaters are very reliable, but on rare occasions there may be a problem that needs to be investigated and repaired. Temperature fluctuation is the most common complaint. There are electrical, gas, and water connections involved with a tankless heater and special tools may be required. In most cases a professional should handle this type of repair.

Problems With Tankless Water Heaters

  • Check setting – The temperature setting may have been changed be mistake
  • Worn seal – If the seal is worn on the crossover water supply, there may be insufficient hot water. You can check this by shutting off the cold water supply to the heater and opening a hot water faucet. The water should stop flowing after a short while. If the water flow continues, the seal is worn.
  • Failed sensor or computer board –  The tankless water heater uses a sensor to monitor flow of water and change firing rate to supply enough hot water. A sensor that is not working correctly may fail to add the required amount of hot water.
  • Water leaks – It is possible that the problem is not in the unit itself. A water leak in your plumbing may be causing hot water to be lost in transit to the appliances.

Even though tankless water heaters are said to produce instant hot water, it does take a few seconds to heat the water to the desired temperature. The water must then travel through the pipes to reach your faucet. Some modern appliances today have a low flow feature which can add even more time for the water to become hot. Taking a few minutes to reach the desired temperature is not uncommon.

However, if you suspect a problem with the heater equipment, a professional should diagnose the problem. Depending on whether you have an electric, gas, or propane heater, a technician will perform the necessary tests to check your heater.

Why Sizing Is Critical When Choosing Your Tankless Water Heater

Why Sizing Is Critical When Choosing Your Tankless Water HeaterHome owners in San Diego and the surrounding areas are becoming more and more energy conscious as utility bills keep going up. A tankless water heater can give great energy savings, but since it only heats water on demand, its important to know you’ve picked the right capacity to keep up with your home’s hot water needs.

So how do you figure out which ones are the right size when looking at what’s available?

Tankless water heaters are rated by the maximum heat increase for a specific flow rate. In order to figure out which one will fit your needs, you first need to figure out the flow rate of any devices you want to be able to run simultaneously, and then how much you need the unit to heat that water. Most tap water requires a heat rise of around 70 to 90 degrees, but that can vary depending on individual circumstances.  So your combined flow rate plus your desired heat rise will give you the optimum size rating for the tankless water heater you’re looking for.

If you add up the flow rates of all your devices, and the flow rate is too fast for your temperature rise, you can buy special low-flow rate aerators and fixtures to put on your faucets to cut down the flow rate. For really high usage households, where multiple people are going to be taking showers at once, or several appliances will need to be using hot water at the same time, you can consider putting in multiple heaters.

One example would be putting one tankless water heater directly next to high usage appliances such as the dishwasher or washing machine, and having another parallel heater that provides the hot water for showers or sinks. If you are considering putting in multiple tankless water heaters, it is best to consult with a professional first to make sure that they will be positioned correctly and able to meet your households needs.
