Water Heater Buying Guide

فکر های نادرست درباره لوازم خانگی
جولای 24, 2017

If your water heater has a 12-year warranty and it’s been in service for 15, it might be time to get a new one. In homes with soft water, which can be tougher on water heaters because of its corrosive effect on the sacrificial anode, a water heater may fail within the warranty period

If you haven’t replaced your water heater in a few years, you’ll find more choices—and more energy-efficient regulations—so do your homework. You may have to spend more up front for a model that will save you money over time

Water heating amounts to nearly 20 percent of a home’s energy costs. As the result of new efficiency standards, water heaters under 55 gallons will see about a 4 percent boost in efficiency, while water heaters 55 gallons or more may cut your utility bills by 25 to 50 percent depending on the technology used

It’s wise to consult a professional or a manufacturer to fully understand the new regulations. Note: We don’t currently have Water Heater westinghouse Ratings, but are able to offer this buying guide, which contains helpful tips and advice

Consider Capacity

Most water heaters are sold on the basis of how many gallons they hold. A family of four, for instance, might take several showers, run the dishwasher, and wash a load or two of laundry in an average day, totalling 100 gallons of hot water or more. But that doesn’t mean they need a 100 gallon storage tank

It’s more important to consider the first-hour rating (FHR) for storage-tank water heaters and the gallons-per-minute rating (GPM) for tankless water heaters because that’s what tells you how much hot water the heater can deliver over a set period of time, i.e., the first hour

After that, depending on how quickly you’re using up hot water, it could either become less hot or actually cool. It would then take a certain amount of time (variable by model and capacity) to return to its full FHR. A pro can help you calculate how much capacity you’ll need.

And while an on-demand water heater doesn’t “hold” any water (unless it has an auxiliary tank), it has a rating of how much hot water it can produce in a given period, known as the GPM (for Gallons Per Minute). You get continuous hot water unless you draw from multiple sources at once, e.g., a shower and the dishwasher. If you frequently do this, you might consider two units
And don’t assume a new water heater will fit where your old one was. Because of increased insulation and other efficiency improvements, some newer models may be wider and/or taller than your old water heater
