## How many BTU’s do I need for my hot water heater?

Input ranges from about 32,000 on a 30-gallon unit to 88,000 on a 100-gallon tank. A common input is 34,000 BTUs on a 40-gallon tank and 36,000 BTUs on a 50-gallon tank. The higher the BTU input and efficiency, the faster the recovery. Electric water heaters typically have one 5,500-watt or two 4,500-watt elements.

## Is 40000 Btu good for a water heater?

At Home Depot, a 40,000 Btu/hr. input, 50-gallon water heater is considered quick recovery. They consider 36,000 Btu/hr. to be standard recovery. If your hot water needs are greater than what a 40,000 Btu/hr.

## What is the difference between 38 000 BTU and 40000 BTU?

A 36,000 BTU water tank is likely to be in the 30- to 40- gallon range. This is the standard in most homes today. The 40,000 BTU water heater is in a 50-gallon tank size. The larger tanks can be slightly more costly to run in the long-term but come with the benefit of more consistent and longer-lasting water heating.

## How many BTU water do I need?

A British Thermal Unit (BTU) is a measurement of heat energy. One BTU is the amount of heat energy required to raise one pound of water by 1ºF. Water weighs 8.33 pounds per gallon so we can calculate that one gallon of water requires 8.33 BTU to raise the temperature 1ºF.

## Are higher BTUs better?

BTU basics A measure of an air conditioner’s power is its BTU rating. BTUs are the energy used to remove heat from a room. Therefore, the more BTUs an air conditioner unit has, the better equipped it is to cool a larger space.

## Is a 50 gallon hot water heater enough for a family of 4?

It’s recommended you have 10-15 gallons of hot water per person in your household. For a family of four, a 50-gallon water heater should be sufficient. Look at the water heater’s capacity, the First Hour Rating (FHR), and your personal Peak Hour Demand calculation.

## Does higher BTU water heater use more gas?

These HE units are so efficient because they extract a high level of heat energy (BTUs) without a lot of waste. They may use the same amount of fuel for the combustion process but they do more with the fuel in less time, which means less fuel consumption overall.

## Does higher BTU use more gas?

The higher the BTU capacity of a gas burner, the hotter the burner can get; the hotter the burner, typically the faster the cooking times. But while BTU measures heat production, it doesn’t necessarily translate into better cooking performance. Some ranges “cycle” heat for low-temperature cooking.

## Is Rheem better than AO Smith?

Both AO Smith and Rheem are great names in the water heater industry. Rheem has a better overall product offering with a higher reach in the industry. But AO Smith is known to have a better customer experience. Regardless of what type of water heater you choose, both options will provide you with excellent longevity.

## Is Home Depot water heater good?

The water heaters available on the shelf at your nearest big-box retailer such as Home Depot, Lowe’s or Menards are a consumer-grade quality, not professional grade. Because the only thing that prevents those 40 or 50 gallons of water from leaking out into your house is the quality and thickness of the steel tank.

## What is the difference between a 6 year and 12 year water heater?

Longevity and Efficiency If you were to buy a 12-year-warranty heater, likely the only difference between it and a 6-year-warranty one would be extra anodic metal: either a larger-diameter hex anode, or a normal one along with a half-length outlet rod in the hot port.

## What is a low NOx water heater?

An Ultra Low NOx gas water heater is one that emits a lower level of nitrogen oxide than a standard gas water heater. Some states and municipalities have requirements and standards to limit the maximum amount of NOx emissions for gas water heaters – particularly certain counties in California and in the state of Utah.

## How do you calculate BTU for a room?

Step 1: Measure The Square Footage (Length, Width, Height Exact To 0.25 Ft)

- Square Footage = Measured Length x Measured Width.
- Square Footage = 16 3/4 ft (Length) x 14 1/2 ft (Width) = 243 sq ft.
- BTU Requirement = 500 sq ft x 20 BTU per sq ft = 10,000 BTU.
- Accurate BTU Calculation = 20,000 BTU * 1.1 + 600 BTU = 22,600 BTU.

## How do you calculate BTU for a house?

For example, a 300 square foot room typically requires 7,000 BTUs to maintain a comfortable temperature, while a 1,000 square foot room requires 18,000 BTUs. A simple formula to determine your heating needs is: (desired temperature change) x (cubic feet of space) x. 133 = BTUs needed per hour.

## How many BTUs Do I need to boil 5 gallons of water?

There are 8.35*5=41.75 lbs in 5 gallons. To take water from 75 to 212 therefore requires: (212-75)*41.75= 5720 BTU.
