Tankless Water Heater Buyer’s Guide

Overall Size

It may seem strange that you need to consider the size of your tankless water heater, but this is actually a very important thing to look at. You want to make sure that it’s going to have enough of a flow rate to run everything you need it to. You need to know all of the flow rates for your devices in order to make sure that your water heater is going to be able to manage it. This may require a little bit of effort on your part to make sure you’re finding the right rates and the right unit that will help you with it.

Temperature Rise

Next, you want to make sure that you’re going to get the right amount of temperature rise from your water heater. The temperature rise is how much the water heater warms up the water that is coming into it from the ground since you’re getting water directly from the ground to the source that you’re using (like a washer or shower). You need your water heater to be able to increase the temperature quickly and to the right temperature for your use or you’ll end up with cold water instead.

Energy Savings

Next, look at how much it’s going to save you over time and how much you would be spending with a traditional water heater. You’ll spend more on average for a tankless water heater than you will for a traditional one so you want to make sure that you know what you’re actually going to get in return. The energy savings from your tankless heater should be a decent amount, but you definitely want to know what that amount is going to be before you jump in and choose one.

Ease of Repair

Finally, make sure that you’re going to be able to repair your unit quickly and easily. You never know when something could go wrong and you don’t want to need a completely new water heater rather than just fixing a couple pieces that might be broken. Make sure the water heater you choose is going to be simple to repair and that it’s not going to require too many repairs as well. After all, you don’t want your brand new water heater to suddenly start needing everything replaced soon after you buy it.

Overall, a tankless water heater is definitely going to be a great choice and is going to provide you with a whole lot of benefits. By lowering your energy costs and increasing your efficiency you’re definitely going to notice the difference in your bills and with the increased floor space you’re going to love your house even more because you can do more with your own space. There are plenty of reasons that you should be checking it out and making sure that you get one installed for yourself, as soon as you possibly can.
