Water Heater Toilet: How It Works and Benefits

A water heater toilet, also known as a tankless toilet, is a game-changer for water efficiency.

These toilets use a combination of a cistern and a heat exchanger to warm the water before it's used for flushing.

This innovative design can save up to 80% of water compared to traditional toilets, which is a significant reduction.

The tankless design also eliminates the need for a separate water heater, making it a more compact and space-saving option.

Bidet seats with tank type water heaters have an internal reservoir of stored water that's heated to the user's desired temperature. This type of heater has been on the market for decades and is extremely reliable.

The warm water from tank type heaters lasts about 30 seconds before it starts turning cooler. It usually takes about 5 minutes for the bidet seat's water tank to fully re-heat.

Bidet seats with tankless water heaters don't keep a reservoir of stored water, instead heating the water stream instantly when the wash is activated. This type of heater is more energy efficient since it only activates during wash.

Bidet seats with tankless water heaters tend to be more slim and low-profile since they don't have internal water tanks in the rear. However, the initial 1 second of wash will be room temperature before the water heats up.

Bidet seats with hybrid water heaters are a combination of tank and tankless types, utilizing a smaller reservoir of pre-heated water while continuously heating the water during a wash. This style of heating provides unlimited warm water.

Hybrid heated bidet seats can have higher spray pressure than tankless models, but this is not always the case. They're also more energy efficient than tank type bidets.

Bidet seats with tank type heaters have higher spray pressure due to internal water pumps and the ability to build up pressure inside the tank. This usually provides a quicker wash.

The peak wattage of tankless bidet seats is around 1400W, compared to tank type bidets which draw a lower peak wattage of roughly 600W.

There are several bathroom heating options that can be paired with a water heater toilet, including electric floor mats.

These mats can be placed under the floor and can be controlled by a thermostat, providing a warm and cozy feeling underfoot.

Some water heater toilets come with built-in heating elements, such as hydronic heating systems.

These systems use hot water from the water heater to warm the bathroom, providing a consistent and even heat.

Electric towel warmers can also be installed in the bathroom to provide a convenient place to dry off after a shower.

They can be placed on the wall or on a countertop and can be controlled by a thermostat or timer.

Some water heater toilets also come with a built-in drying function, which uses hot air to dry the user after a shower.

This can be a convenient and energy-efficient way to dry off after a shower, especially in colder climates.

The water heater toilet is a game-changer for small bathrooms, but it's not without its technical considerations.

The water heater unit is usually installed under the toilet tank, which can take up valuable floor space.

You'll need to ensure the toilet and water heater are properly vented to prevent moisture buildup and ensure safe operation.

The water heater toilet typically uses a tankless design, which can be more energy-efficient than traditional tank-style water heaters.

Some water heater toilets come with built-in thermostats, which can help regulate water temperature and prevent scalding.

The water heater unit usually has a flow rate of around 1.6 gallons per minute, which is suitable for most residential uses.
