Higher input means the water heater can heat more water faster when needed. Natural or propane gas input is expressed in BTU’s (British Thermal Units) per hour, and State gas inputs range from 30,000 to 75,100 BTU’s.
Do you want higher or lower BTU water heater?
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. Two lower-kilowatt elements will heat much faster than one higher-wattage element.
How many BTU water heater do I need?
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.
What does higher BTU on water heater mean?
A BTU is the quantity of heat needed to raise one pound of water by one degree Fahrenheit. More BTUs mean more heating power.
Does higher BTU use more gas?
Natural gas and LP are sold by the BTU so the more BTU’s a burner uses per hour the more it will cost to burn the appliance.
What should I look for when buying a hot water heater?
When selecting the best type and model of water heater for your home, consider the following: Fuel type, availability and cost. The fuel type or energy source you use for water heating will not only affect the water heater’s annual operation costs but also its size and energy efficiency. Size. Energy efficiency. Costs.
How many BTU does it take to heat a gallon of water?
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.
What does Ultra Low NOx mean?
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 many BTUs do I need for a shower?
The typical gas heater has an energy factor of around 0.6, so you’d need about 17,000 Btus of gas input to warm your shower. If you used a typical electric water heater, with an energy factor of around 0.9, the same shower would consume 12,000 Btus of electricity.
How do I calculate BTU for water heater?
BTU = Flow Rate In GPM (of water) x (Temperature Leaving Process – Temperature Entering Process) x 500.4*Formula changes with fluids others than straight water.
How many BTU stove do I need?
For most users, one power burner (12,000 BTUs or higher) is more than adequate—especially when paired with two medium-strength burners and one low burner for simmering. If you do a lot of cooking that requires quick high heat, such as stir-frying or searing, you may want to push the power up.
Is a 40 gallon water heater enough?
Typically, the rule-of-thumb is that you want a 40 gallon tank for 1 to 4 people, a 50 gallon tank for 4 to 6 people, and a 50 gallon high recovery or 75 gallon tank for 6 to 8 people.
Is there a big difference between a 40 gallon and 50 gallon water heater?
The Energy Factor The cycling losses measure how much heat is lost as the water circulates through the system. With the energy factors being equal, the difference in cost of running a 50-gallon heater over a 40-gallon heater is essentially insignificant.
Is 15000 BTU enough for cooking?
For home cook, in an example of 4 burner gas cooktop, one power burner of 15,000 or a little higher, paired with 2 mid strength burners and one low burner for low temperature cooking and simmering is good enough. The design, the body, parts and features are all important factors while shopping for the best cooktop.
Is the higher the BTU better or worse?
A heater with a higher BTU rating is more powerful — that is, it has a higher heat output — than one with a low BTU rating. It can do more to raise the temperature in your room each hour, so you can either heat a room more quickly or heat a larger space.
Is 18000 BTU enough for cooking?
Middle: 2,000–10,000 BTUs. Mid-range BTUs are good for everyday cooking like sauteing and frying. High: 12,000–18,000 BTUs. These high BTU burners are meant for high heat cooking like searing and stir-frying.
