Buying guides

A condensing tankless water heater is a type of tankless water heater that uses condensing technology to extract more heat from the fuel it consumes. This results in higher efficiency and lower operating costs compared to traditional tankless water heaters.

Condensing tankless water heaters work by burning natural gas or propane to heat water as it flows through the heater. As the water flows through the heater, the heat exchanger captures the heat from the burning fuel and transfers it to the water. The exhaust gases produced by the burning fuel are then passed through a second heat exchanger, where the heat is extracted and used to preheat the incoming cold water. This process helps to extract more heat from the fuel, resulting in higher efficiency and lower operating costs.

Condensing tankless water heaters are a popular choice for homeowners because they offer a number of benefits, including:

Continuous hot water: Tankless water heaters provide a continuous supply of hot water on demand, eliminating the need to wait for a tank to refill.

Energy efficiency: Condensing tankless water heaters are more efficient than traditional tankless water heaters, which means they can save you money on energy costs.

Space savings: Tankless water heaters are smaller and more compact than traditional tank-style water heaters, which means they can save you space in your home.

Long lifespan: Tankless water heaters have a longer lifespan than traditional tank-style water heaters, which means they can save you money on replacement costs over time.

There are a few key factors to consider when buying a condensing tankless water heater:

Fuel type: Condensing tankless water heaters are typically powered by natural gas or propane. Choose the fuel type that is most convenient and cost-effective for your home.

Size and flow rate: Make sure to choose a tankless water heater that is the right size for your home's hot water needs. Consider the number of bathrooms, the type of fixtures you have, and the overall hot water demand in your home.

Efficiency: Look for a water heater with a high energy factor, which indicates how efficiently the heater converts fuel to heat. The higher the energy factor, the more efficiently the heater will operate and the lower your energy costs will be.

Venting options: Condensing tankless water heaters require proper ventilation to function properly. Consider the venting options that are available and choose the one that best fits your home.

Price: Tankless water heaters can vary in price depending on size, efficiency, and other features. Determine your budget and look for a water heater that fits within your price range.

Warranty and customer service: Look for a water heater with a good warranty and strong customer service. This will give you peace of mind and help protect your investment in the event of any issues.

It is also a good idea to do your research and read reviews from other homeowners who have purchased and used the same or similar water heaters. This can help you make an informed decision and choose the best water heater for your needs.
