What to Look for When Buying Electric Water Heaters
An electric hot water heater is an appliance that, if carefully chosen, can last for decades. Several factors based on projected usage, space, energy sources and investment options require consideration before purchasing a new electric water heater. Does this Spark an idea?
-
Capacity and Recovery
-
Choosing the right--sized water heater and good recovery features ensures hot water needs are efficiently met. Conventional tank water heater needs are based on the home's number of occupied bedrooms and regularly used bathrooms. Tank sizes range between 20 and 80 gallons. For heavy usage, a tank with a fast recovery rate is best. Tankless system needs are calculated on a per-use or flow basis, so the flow rate of faucets and major appliances must be determined to choose the right size.
Dimensions and Location
-
If upgrading a conventional water heater, consider that the extra insulation required for new models demands more space. Tankless systems need placement in properly ventilated areas with easy access to electrical outlets and gas and water lines.
-
Other Factors
-
Self-cleaning tank water heaters generally operate more efficiently and last longer because the systems regularly rid the tank of sediment and lime buildup. Tank systems cost less than tankless ones, but the latter can reduce energy expenditures up to 30 percent.
