Expert Answer

Usually, it can be done within two hours. If you have to do any draining, though, it might take just a little bit longer, because part of the hot water heater can be a little calcified.

Where should I install a water heater in my home?

Question

Which rooms are unsafe for installing a water heater?

Community Answer

A room with carpeting is unsuitable because it can be difficult to clean if the heater leaks. The attic is also unsafe as it can cause significant damage if flooding occurs. Bedrooms and playrooms pose risks, and installing a water heater behind a locked door is problematic if access is needed in an emergency.

Question

Why does the water heater have to be on blocks?

Community Answer

Placing a water heater on blocks is needed for safety reasons. If a water heater is installed in a garage, it has to be elevated at least 2 feet (61 cm) above the ground to prevent cars from driving into it. This rule doesn't apply to laundry rooms or outdoor areas.

Question

Why is a vent shaft necessary for a water heater installation?

Community Answer

A vent shaft allows harmful gases like carbon monoxide, produced by the water heater, to safely exit the home. It’s essential for preventing gas buildup in enclosed spaces, especially if the heater is installed in a confined area like a closet.

Question

Why are certain rooms more suitable for installing water heaters?

Community Answer

Water heaters are best installed in areas like the garage, basement, or outdoor cabinets, as these locations typically have hard flooring or concrete, which is easier to clean in case of leaks. Additionally, water will more likely flow outside or below ground in these areas, minimizing potential damage.

Question

Should the water heater and washing machine be installed close to each other?

Community Answer

Yes, the water heater and washing machine can be installed close together if desired. The water heater supplies water to all devices that use water, including sinks, washing machines, and baths. Whether they are close or further apart depends on your house's layout, but both setups can work effectively.

Question

Which room should be on the opposite side if a water heater is installed outside the house?

Community Answer

It doesn't matter which room is on the opposite side, but having a water-using room like a bathroom, laundry room, or kitchen nearby is more convenient. Typically, water heaters are placed near the garage or laundry room.

Question

Why are water heaters typically installed in laundry rooms rather than bathrooms?

Community Answer

Water heaters are usually installed in laundry rooms because it is safer and more convenient. The risk of hot water contact and burns is lower in a laundry room, and the proximity of water pipes to the washing machine makes installation easier. Additionally, locating the water heater away from bathrooms helps to manage water flow and prevent overloading.
