Hot Water Heaters

There are two types of water heaters: tank and tankless.

What’s The Difference? Conventional Gas Hot Water Heaters Vs. Conventional Electric Hot Water Heaters

Tank Water Heater

Tank heaters are just what they sound like. Large containers, with a heat source that raises the temperature of the water until needed. There are 3 common types of gas heaters and 2 common electrical heaters.

Tankless Water Heater

奇米影视第4色Tankless heaters are just as they sound too. Instead of storing hot water, they create hot water on demand. You can find more information on this below.

Conventional tank heaters come in 5 common types; 3 of these heaters are fueled by gas and 2 by electricity. Conventional gas tank heaters either use liquid propane (LP) or natural gas in most cases you find LP where there is not a natural gas provider. They have a tank, burner and gas valve that works with a thermostat to control the amount of hot water. Most gas heaters have a thermocouple or thermopile to keep the pilot assembly safe. Thermocouple repairs are the most common problem with conventional heaters.

奇米影视第4色Because these heaters are burning fuel, they require venting to release the toxic gases. The 3 types of heater are distinguished by their method of venting

1) Atmospheric Vented (62-67% efficiency):奇米影视第4色 this is the most common heater in residential homes. The reason it’s called ‘Atmospheric Vented’ is because the exhaust from the heater exits the home through the rooftop. Life expectancy is 12-15 years.

Pros:奇米影视第4色 Inexpensive, parts commonly available, simple and reliable design, stores hot water during power outages.

Cons:奇米影视第4色 Least efficient option, short lifespan compares to tankless.

2) Direct Vented(62-67%): this is a specialty heater, designed for applications where the venting can not be vented through the rooftop for some reason (second story), but can be vented horizontally directly behind the heater. These heaters have many similar parts to the atmospheric vented heater. Their life expectancy is 12-15 years. Based on cost, most people consider tankless as an alternative.

Pros: These heaters offer the least expensive solution to vent directly horizontal.

Cons:奇米影视第4色 These are expensive, they are inefficient, they no longer make 75 gallon

3) Power Vent (75-85% efficiency):奇米影视第4色 These heaters are designed for applications where the exhaust must be pushed further away… either vertically or horizontally. They use a fan to push the exhaust and bring up the heat for better efficiency. They require a 110 outlet to drive the fan and electronics.

Pros:奇米影视第4色 These heaters are an option for 75 direct vent replacement. They are more efficient than the atmospheric and direct vent option.

Cons: These are expensive, with a modest 12-15 yr lifespan. For coat vs performance, the tankless heater should be considered.

4) Electric Tank:奇米影视第4色 Electric tank heaters use an electric element and the voltage passes through to create hot water. Typically, the residential whole house heater runs on a 220 volt, 30 amp power source to energize one or two elements controlled by a thermostat mounted to the tank. Electric heaters are seen in homes that do not have any gas service or no way to ventilate exhaust gas.

Pros:奇米影视第4色 Typically less expensive, simple design, inexpensive parts,

Cons:奇米影视第4色 Expensive compared to gas options, tank size limited to 50 gallons in residential setting and some jurisdictions will not allow them if gas is present at the home.

5) Hybrid Electric (3.74 efficiency):奇米影视第4色 Hybrid electric heaters have two types of electrical heating; they use heat pump technology to create hot water, similar in principle to how a refrigerator makes our food cold… only in reverse order. The heater also has an electric element, like the conventional electric heater, to meet demands.

Pros:奇米影视第4色 Much more efficient when operating in heat pump mode (5x better than standard Electric) and power company incentives (SMUD rebates $3000) when converting from gas to Hybrid.

Cons:奇米影视第4色 Much slower recovery (most cases suggest increasing tank size), expensive equipment, retrofitting adds cost, lifespan is 12-15 years.
