General FAQ

What is a tankless water heater?

Tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only as it is needed. They don't produce the standby energy losses associated with storage water heaters, which can save you money.

What are the benefits of a tankless water heater?
  • Tankless water heaters are compact in size, taking up less space than conventional tank type water heaters.
  • They can virtually eliminate standby losses - energy wasted when hot water cools down in long pipe runs or while it's sitting in the storage tank.
  • By providing hot water immediately where it's used, tankless water heaters waste less water. You don't need to let the water run as you wait for hot water to reach a remote faucet.
  • A tankless water heater can provide unlimited hot water as long as it is operating within its capacity.
  • Expected life of tankless water heaters is 20 years, compared to 10 to 15 years for tank type water heaters.
What should I look for in a tankless water heater?

One of the first things you should do is find out exactly what size tankless water heater you will need. Take a Look at Warranties, and efficiency ratings to make the best selection for your job.

Should I upgrade to tankless water heater?

Using a tankless water heater can reduce these costs by up to 50 percent, for an average annual savings of $80 per 50 gallon tank replacement. They are durable and less likely to fail, causing potentially catastrophic flooding in your home. Tankless units have an average lifespan about twice that of conventional water heaters — 20 years or more

Can you run out of hot water with a tankless water heater?

With a tankless system, there isn't a supply of hot water that can be depleted. Instead, the water heater heats up water as there is a demand for it. ... It will keep doing this as long as there is demand—and that means you won't run out of hot water.

Intellihot FAQ

When/why should I cascade my units?

We recommend cascading units when you have a common exhaust system. This is a system where multiple units terminate through 1 pipe, to prevent back pressure from locking out your units on a Blocked Flue Fault.

What is the difference between a fault and a service alert?

How do I determine warranty? Is my unit still under warranty?

We have two separate warranties. Heat Exchanger warranty and Parts warranty.

Warranty information is found in sections 18 &19 in your owner’s manual. 

 

To determine either warranty, refer to your units serial number. The first 6 digits of your serial number are the year we go by when determining warranty. However, if your unit was purchased earlier with a manufacturing date of say, 2018 but installed in 2019 or 2020, we would need documentation from the installation and that would suffice.

What does the, "inadequate flow," screen mean?

You'll only receive this prompt while in combustion mode. While in this mode your unit does not modulate, so you'll need to simulate the amount of BTUs required for it to fire. This entails opening any/all nearby faucets. You may also open your pressure relief valve on top of the unit to force flow water and increase your GPMs(gallons per minute). Please be careful when opening your pressure relief valve though, you'll want to make sure you're not within distance of the hot water.

Is there a remote/emergency shut-off?

No, to shut off the unit you'll need to either unplug it or directly hit the rocker switch located behind the front door in the upper left corner.
