How to maintain your hot water tank (for both Gas and electric)

So [00:00:30] today I'm in the basement of a home with Harman Dhillon, with Brookfield Residential and today we're going to talk about how to maintain your hot water tank, specifically how to maintain both a gas and electric hot water tank.

Similarities between gas and electric

Karl Yeh:                              So Harman, can you tell us about the similarities between both?

Harman Dhillon:               

We've got a lever here that can be closed and that allows water not to enter the tank anymore.

On the spout, you can attach a garden hose and place it into the drain and you can take a flathead screwdriver and open up the valve, draining the tank.

Harman Dhillon:               

Both tanks will also have a pressure relief valve on them, [00:01:00] so if you see a little bit of water on the floor, it's just releasing some of the pressure in the tank.

Karl Yeh:                              Okay, and

What are the differences between the two?

Harman Dhillon:               

This tank is a gas tank, so this one will be powered by gas.

It will have a regulator, which also has a setting knob on it that changes the heat value inside the tank and then also a on off switch on it.

We're an electric tank will be powered by electricity.

Karl Yeh:                              So Harman, do you have anything else add?

Harman Dhillon:               


For the gas tank for winter maintenance, there's a chance that the tank could shut off.

A lot of the [00:01:30] times it's the vents outside that are blocked with snow and ice from the extreme cold that we have.

What you want to do is come back, come down in here, unplug your tank, go outside, clean off the snow and ice that is preventing it from exhausting, come back in and just plug it back in.

The tank should re-light itself and you should be good to go. Perfect.

Karl Yeh:                              Let's go check out the electric.

So we're in a new house, a new basement talking about an electric hot water tank.

So Harman,

What's the first thing we need to do in terms of maintenance?

Harman Dhillon:               

You want to come to your breaker box and you want to find your hot [00:02:00] water tank breaker, and we're just going to flip it off.

Karl Yeh:                              Perfect. Let's go over to the hot water tank.

Harman Dhillon:               

So now that we've turned off the breaker, what's the next step? Just like your gas tank, you want to shut the lever off up here.

This prevents any water from filling up the tank. You can now put a garden hose on your spout here and place it on your furnace drain.

You can then take a screwdriver and open up the valve. This allows the tank to drain completely.

Once the tank is completely drained, you can shut the valve off here.

You can disassemble your garden hose [00:02:30] off of your spout and open up the lever up here.

Give the tank about five minutes to fill back up, and then turn your breaker back on.

Karl Yeh:                             

So what's the difference between this one and the gas one that we just saw?

Harman Dhillon:               

Well, the obvious difference is the gas one is powered by gas and has a regulator. This one is powered by electricity and has two elements that heat up the cold water, just like a light bulb does.

Karl Yeh:                              Perfect. Do you have anything else to add?

Harman Dhillon:               

Yeah, just remember, just like light bulbs burn out, your elements can burn out and eventually will burn out and will need replacing.

Karl Yeh:                              [00:03:00] Perfect.
