Q: Is it better to vent a gas water heater out of the wall or roof?

• <div><p>Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you&rsquo;re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.</p></div>

Q: When should I replace my water heater?

• <div><p>Replacement should be considered when repair costs exceed half the price of a new unit, if the heater is more than 10-15 years old, or if consistent issues hinder its effective functioning despite multiple repairs.</p></div>

Q: Can you vent a gas water heater out the side of the house?

• <div><p>You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. </p><p>Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.</p></div>

Q: How long should a water heater last?

• <div><p>How long a water heater lasts depends on the type. A conventional tanked water heater has an average lifespan of eight to 12 years. Tankless models typically last a little longer, anywhere from 10 to 15 years. Regular maintenance can help you extend the life of your water heater and keep operating costs in check.</p></div>

Q: What is the most efficient type of hot water heater?

• <div><p>Heat pump water heaters, also known as hybrid water heaters, are the most efficient types of water heaters&mdash;both in terms of carbon emission and energy efficiency. This type of water heater utilizes as little as half of the energy of a traditional water heater while releasing no direct emissions. Tankless water heaters are also extremely efficient, although slightly less so than hybrid heaters.</p></div>
