What is a Ventless Tankless Water Heater?

A ventless tankless water heater is a compact and energy-efficient alternative to traditional water heaters. Unlike traditional models, which store hot water in a tank, a ventless tankless water heater heats water directly as it passes through the unit.

– Energy-efficient: As hot water is only heated when needed, there is no standby heat loss like with traditional models. This results in significant energy savings.
– Cost-effective: While the initial cost of a ventless tankless water heater may be higher than traditional models, the energy savings over time make it a cost-effective choice.
– Hot water on demand: With a ventless tankless water heater, you’ll never run out of hot water as it heats the water as it flows through the unit.

Factors to Consider before Buying

Before purchasing a ventless tankless water heater, there are some important factors to consider:

– Size and Flow Rate: It’s essential to choose the right size and flow rate for your household’s needs. The size will depend on factors such as the number of bathrooms and appliances that require hot water.
– Fuel Type: Vent-less tank-less heaters are available in both electric and gas options. Consider which fuel type is readily available and most cost-effective in your area.
– Installation Requirements: While vent-less heaters do not require ventilation systems, they do need access to gas or electricity and proper drainage.
– Cost: The initial cost of purchasing a vent-less tank-less heater may be higher than traditional models; however, consider the long-term savings on energy costs.

Some top brands that offer high-quality vent-less tank-less heaters include Rinnai, Rheem, Bosch, Noritz and Takagi.
