How to Turn On Hot Water Heater in Apartment: Tips from an Expert

Many apartments come with a water heater that is not accessible to residents. This can be especially frustrating on those cold winter mornings when you want a warm shower or a cup of tea, but no hot water comes out of the faucet. Luckily, there are some steps you can take to make your apartment’s hot water work for you! In this blog post, we will discuss how to turn on hot water heater in apartment from an expert in the field.

How to Turn On Hot Water Heater in Apartment?

In some apartments, the hot water heater is not accessible to residents. However, you can make your apartment’s hot water work for you!


  • If you live alone and don’t have a roommate who would be affected by this change, simply go into your unit’s breaker box and flip off all switches that might affect your tankless heater or water heater.
  • If you live with someone, talk to them about this and make sure they agree before turning off the breaker for your unit.
  • Once all of the switches are turned off, or if no switches were affecting your hot water tank, leave it like that overnight – at least eight hours but not more than twenty-four hours.
  • After your time is up, go back to the breaker box and turn all switches on again.
  • Wait a few minutes for any hot water that may have been lost during this process to come back into your faucets.
  • Then, test out your shower or sink – you should be able to get hot water from these appliances now!

When should you call the plumber?

When you’ve tried out these steps, and your hot water still doesn’t work, don’t panic.

There may be some bigger issues with the boiler or other things that could lead to a faulty unit, as well as problems within your tankless heater. If it’s been more than twenty-four hours since turning off all switches in your breaker box and trying out these steps, you should then contact a local plumber.

Why the hot water heater in your apartment goes out?

Some apartment buildings’ industrial-sized hot water units are not designed to run constantly or provide hot water for real-time usage.

It runs only around the clock, but when all of your neighbors in a building take showers at once and fill up their sinks with boiling water – it can lead to the unit running out of hot water really fast!

The best way to avoid this problem is to not use your hot water heater unit for anything but cooking and drinking.


  • Never leave the faucet on when you’re brushing your teeth or shaving because that can cause a lot of unnecessary strain to be put on the system all at once!
  • It’s okay if it takes a few minutes longer for your shower to get hot water because the hot water heater will recover.
  • It’s not okay if you’re constantly turning on the faucet to fill your sink with hot water because that will be overworking the system, and it could lead to a complete shut-off of hot water for everyone in the building.
  • Don’t panic, but don’t waste time either – turn off all unnecessary appliances or switches that could lead to hot water being wasted.

With these tips on how to turn on your apartment’s hot water heater from an expert in the field, you’ll never have a cold shower again!

FAQs: Turning On Hot Water Heater in an Apartment

How do I turn on my hot water heater?

This is typically done by turning the temperature knob to 90 degrees. If it’s turned off, there should be a little arrow pointing up. If it’s turned all the way down to 60 degrees, the temperature control is probably in “vacation” mode and will need to be switched back.

Where is my hot water heater located?

Your unit should be near your main gas valve, which is usually in your basement. If it’s not there, it might be in your furnace room, usually in the same area as your basement.

Why won’t my hot water heater turn on?

The most common reason for this problem is that the main gas valve is turned off. If this is the case, then you’ll need to contact your landlord or property manager for assistance.


A hot water heater that is not accessible to residents can be frustrating on those cold winter mornings. The first thing you need to do is call a plumber and have them come out to inspect the problem–don’t try anything else until they determine what needs fixing or replacing!

After calling a professional service provider, it’s time for step two: turning up the temperature inside the tank at night so that when people wake up in the morning, there should already be plenty of warm water waiting for them.
