Tankless Water Heaters
Hot water is used for a variety of things each day, including taking showers and baths, doing laundry, and washing dishes. All of this hot water is provided by your water heater, and a tankless water heater is a great option that allows instant access to hot water. Tankless water heaters are a fast and effective way to heat the water that feeds your home, and these products can range in capacity, temperature, flow rate, and more.
What are the benefits of having a tankless water heater?
- Energy Usage: Tank water heaters work by heating all of the water in the reservoir and keeping it hot all day long. Tankless units on the other hand, constantly cycle water through the unit but do not heat it until it is needed. When a faucet is turned on, the heating coils inside the tank heat up, instantly warming the water in the pipes. Since tankless heaters do not stay on throughout the day, they conserve energy.
- Endless Hot Water Supply: Since these water heaters work by instantly warming the water running through them rather than preheating it, tankless systems are able to provide an endless supply of hot water.
- Storage Space: Tankless heaters are able to hang on the wall, freeing up floor space beneath them.
What flow rate is required for your tankless water heater?
These water systems measure their capacity in flow rate, which states the number of gallons of hot water per minute that the heater can produce. Different appliances utilize varying amounts of warm water. Showers often use around 2.5 gallons per minute, a dishwasher uses 1.5, and washing machines use 2. To determine what flow rate you require, you must consider how much hot water you will need at a single time, such as for simultaneous showers, running the dishwasher, and more. Adding up the individual flow rates for simultaneous usage will provide you with the overall flow rate that you need for your water heater.
What energy source do tankless water heaters use?
- Gas: Some water heaters utilize gas in the form of kerosene or propane. Gas products are able to heat water quickly and effectively, and they generally offer high flow rates. Some gas water heaters utilize a pilot light, which maintains a small flame throughout the day for rapid response time, while other gas models can utilize intermittent ignition devices, which can save energy and fuel.
- Electric: Electric water heaters are very efficient and reliable, as they do not require combustion for heating. Electric models also do not require any outside ventilation, which can make installation much easier, as there are no piping or vent system additions required.
