First check for plumber's tape
Experts modified the procedure for strapping water heaters following the 1989 Loma Prieta and 1994 Northridge earthquakes. Prior to this, a single strap of plumbers' tape was commonly used. Because so many tanks burst through this strapping, experts now recommend:
Second, secure tank with heavy-gauge metal straps, top and bottom
Commercially available strapping kits make this a relatively easy process. These can be found in many hardware stores on the aisle displaying the water heaters. These kits come complete with the strapping, lag screws, washers, spacers and tension bolts.
An emergency source of water
Water can easily be accessed by connecting a garden hose to the drain spout, and by opening a faucet somewhere in the house.
What is an anode rod?
The anode rod produces a low resistance electrical current to establish an electrical circuit in the water heater that controls corrosion through cathodic protection. Cathodic protection can be defined as a means of protecting a surface from corrosion by making that surface cathodic through the use of a current derived from an anode.
Why do water heaters have anode rods?
This naturally induced voltage is created due to the potential difference between various metals (batteries are based upon this same principle). Anode rods help protect your water heater's glass lining and water heater tank from the corrosive characteristics of your incoming water.
Why do water heaters switch off?
Each water heater has a differential temperature range to keep your water heater at your desired temperature. In the rare case that the water temperature vastly exceeds this temperature range, it will switch off to keep your home safe. If you experience overheating within your water heater, we recommend that you consult a professional plumbing ...
Why does my T&P valve leak?
In the unlikely case that the water temperature vastly exceeds the nominal temperature or the pressure is substantially higher than nominal, the T&P valve may open to release excess pressure and hot water. Water expands during the normal water heating process, creating higher pressure inside the tank. We generally recommend the use of an expansion tank to keep the pressure in the tank at a reasonable level. If an expansion tank is not used, then the expanded water has nowhere to go and it will increase the pressure in the system. A leaking T&P valve may indicate an unsafe temperature or pressure situation. If this occurs, we recommend that you consult a professional plumbing contractor for assistance.
Why do you line the inside of a water heater with glass?
By lining the inside of the water heater with glass, heat stays within the tank and protects the steel exterior from rusting and becoming a safety risk.

What is an instant hot water heater?
An instant hot water heater is a heating system that warms water on-demand, rather than storing hot water in an insulated tank. That means instead of measuring the volume of hot water produced by the unit, as we might with a storage water heater, we measure flow rate in gallons per minute. Typical units can heat between 2 and 5 gallons of hot water per minute. Instant water heaters use either electricity or natural gas to rapidly heat water as you use it. That means your water heater sits idle until you need it to work. Storage water heaters, by comparison, heat a large volume of water and store it for instant access as needed.
Why use an instant heater?
Another benefit of an instant heater is the speed with which they can heat your water. In many cases, you’ll have hot water within seconds of turning on the tap. This reduces wasted water and improves home comfort and convenience — no more standing around waiting for the shower to heat up!
Is instant hot water cheaper than storage water heaters?
Instant hot water heaters are typically cheaper to operate over the span of their existence than storage heaters. They use far less energy than older storage units per gallon of water heated. Since many tankless heaters need to be replaced half as often as a traditional storage water heater, the increased up-front cost of installation will usually be offset over the life of the unit. Instant water heaters are also safer. There is less risk of flooding or water damage since these units don’t have a tank that could spring a leak. They’re also easy to shut off if you leave for vacation and don’t require draining if you plan to be away for a long time.
Is a gas water heater better than an electric water heater?
Gas instant hot water heaters are typically less efficient than electric, but usually provide more gallons of hot water per minute. Electric models are extremely efficient — up to 99% of the electricity gets converted directly to heat. Compare that to older storage heaters that can operate at as little as 67% efficiency, and you start to get an idea of why many families are interested in switching to tankless instant heaters!
