"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet. I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."
When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.
In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.
There are pros and cons to tankless water heaters. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact. On the other hand, they cost about twice as much to install as traditional tank water heaters and are more limited in terms of flow rate.
While a water heater explosion is rare, it is a serious danger. Be aware of these critical warning signs:
Sulfur or Rotten Egg Smell: This is a major red flag, especially for gas water heaters. It can indicate a gas leak, which could ignite and cause an explosion.
Leaking Pressure Valve: If the temperature and pressure (T&P) relief valve is leaking, it may not be able to properly regulate internal pressure, creating a risk of bursting.
Shaking or Rumbling: Loud rumbling or shaking from the tank can be a sign of extreme pressure buildup.
Excessive Heat: If the exterior of the water heater feels unusually hot to the touch, the unit may be overheating dangerously.
Rust-Colored Water: This can be a symptom of severe internal corrosion that compromises the tank's integrity.
If you notice any of these signs, especially a gas smell, you must act immediately. Shut off the gas supply to the water heater and call a professional plumber right away to prevent a potential disaster.
It’s important to find the type of water heater that fits your needs and budget. Depending on the type of water heater, size, brand, and the type of energy you use to heat the water, costs range from a few hundred dollars to several thousand.

Electric: $600–3,500
Gas: $700–$2,700

High efficiency: $1,500–$3,000
Indirect: $1,200–$3,500
Hybrid heat pump: $1,200–$3,500
No state requires you to vent an electric water heater. Other installation requirements for water heaters will vary, though, depending on the state and local jurisdiction in which you live. Some places require permits, while others don’t. Some may force you to place the appliance a certain distance from any walls or other appliances, while others don't.
