When you are deciding on a new hot water heater from HVAC Direct, one of the main concerns is size. You don’t want to get too big of a unit because you will waste energy heating water that just sits in the tank. On the other hand, you don’t want to come up with hot water in the middle of a shower, either. The guidelines for purchasing the proper size heater for your home can be calculated by figuring out what FHR or first-hour rating of the water heater you need. To come up with this number, you should figure 12 gallons of water per person in the household, plus one more. If you have five people, then you would take six times 12 to get an FHR of 72.
Most new home construction will take the number of bedrooms and add one to calculate the size of the unit, so if you are buying new construction, you can figure that a four bedroom home was calculated by taking five times 12, giving you an FHR of 60. Where the problem could come in is if you have more occupants that take long showers, you might expect to come up with hot water if you all get up and take showers first thing in the mornings.
When it comes to calculating expenses for energy efficiency, you will want to get the unit with the highest EF rating, or energy factor, for the FHR number you need. The FHR number was created by the National Appliance Energy Conservation Act, as a guideline for contractors, who had minimum building codes they had to follow for HUD before the creation. The FHR is a more realistic number that is tied to usage, yet is not overly generous in capacity to contribute to energy waste.
It used to be that most homeowners would purchase a new hot water heater larger than their previous one, if they ran out of warm water very often, but it might not necessarily be the exact size they need and the energy they waste with too large of a hot water may far outweigh coming up with schedules for the household to shower. This is especially true of households with young children that can waste a lot of hot water in the bath or teenage girls that waste a lot washing hair and messing around in the shower.When you are deciding on a new hot water heater, one of the main concerns is size.
If you purchase a water heater with the proper FHR for your household, chances are that heat is being wasted through other means, or hot water usage is not evenly distributed. Obviously, if you are running the dishwasher, doing laundry and taking showers at the same time, you will come up short on boiling water with any quantity of water radiator. Vitality protection includes good judgment and flexibility, but you can save a lot of money by purchasing the water heater that is the right size for your home, and you will see the savings in the utility bills, as well.
