Overcoming Some Of The Drawbacks Of Tankless Water Heaters

If you need a new water heater in your home, then it may be time to install a tankless water heater. These appliances are much smaller than tank units and they also are more energy efficient. However, before you run out to buy your water heater, you should know that there are some drawbacks to the appliances. Keep reading to learn what they are and also how you can overcome them. 

Reduced Flow Rates

Most tankless water heaters are rated in terms of their flow rate. Flow rate is labeled as gallons per minute. When you have a tank water heater, the appliance will put out a good volume of water that far exceeds that of your shower heads or your faucets. Your shower head has a flow rate that is likely about 2 or 2.5 gallons per minute. Your water heater will release enough hot water to handle your shower as well as several other faucets and appliances. In general, you can expect the water heater to release water at least three or four times the rate of your shower head. 

If you purchase a tankless water heater, the flow rate will be far lower. You can expect the rate to equal that of your shower head and another faucet or appliance. This means that you can really only use hot water for one thing at a time. If you need warm water, then you can use two faucets or appliances at once.

You also should know that flow rate will reduce the hotter you want the water. For example, if you turn up the thermostat on the device, then the unit will take longer to heat water for you. It may also take some time to warm up. However, you can reduce these concerns by purchasing a unit that is much larger than your house needs. Also, you can buy two smaller tankless or on demand units instead of one. 

Expensive Units

If you have priced water heaters, then you may learn quite quickly that tankless units are more expensive than tank varieties. A gas variety can cost well over $1,000 dollars. If you want to save money, then you should opt for an electric one that is typically one-third to one-quarter of the cost of a gas appliance. 

While electricity is more expensive than gas, tankless water heaters are far more efficient. This means that you will save money on energy simply by switching to a tankless system, even if it is an electric variety. Efficiency will differ depending on the model of heater you choose, so look closely at the efficiency rating when picking out the unit you desire.
