How do I select a water heater?


Picking the wrong water heater can become a costly mistake. You might pay too much in the beginning for more water heater than you need. Or you might pay too much when it comes to your monthly utility bill if you choose a water heater that’s not efficient enough for your life. Let us walk you through the different things to keep in mind when you’re looking for the perfect water heater.


So you need a water heater. It’s a good thing you’re doing your homework. Picking the wrong water heater can prove to be a costly mistake in the long run. And that’s the first thing you need to know about water heaters: as a general rule of thumb, cheaper water heaters cost more to operate. Trying to save a few dollars at the cash register generally results in paying more in utilities every month.That’s the first thing you should consider, but it’s only one consideration. When you’re choosing between water heater models, pay close attention to the Energy Factor and the Energy Guide label. The Energy Factor is simply a number that tells you how efficient a water heater is. The higher the number, the more efficient the heater. The Energy Guide label will give you the first-hour rating. This tells you how much hot water a heater can supply per hour. Don’t buy a heater that’s going to give you more hot water than you need. You’ll waste money on the heater itself, as well as the monthly utility costs. A 3 bedroom, 1 and one half bath home, for example, needs a 40 gallon water heater. When it comes to the kind of water heater you want, conventional storage water heaters can run on electricity, gas, propane or oil. But you might want to consider a space-saving gas or electric on-demand system. These heat water as it’s needed, which means there’s no wasted space, because there’s no storage tank. And there’s no wasted energy, because you’re not paying to heat water that you’re not using at that moment.There is also solar water heaters. They cost more than conventional water heaters, but what you save in operating costs could make it worth the purchase price.And there are electric heat pump water heaters. They’re also more expensive and need a little more room than a typical water heater, but they do save money on monthly utility bills.When it comes to buying a water heater, look at all the options before deciding what’s right for your home and budget.
