A water heater is what you’d want when you need a shower on a cold, foggy morning. It’s not surprising that many families havewater heatersinstalled in their homes. If you’re one of those people shopping for one, then you may likely be researching water heater dimensions. This is important because you need to know water heater sizes first before deciding that water heater you’d have installed in your home.

Two Types of Water Heaters and Their Sizes
熱水器分為兩儲罐和無罐。重要的是要知道，因為您需要在確定熱水器的正確尺寸之前確定您想要的熱水器類型。
無油墨熱水器也被稱為按需熱水器。隻有在您呼叫後，它才會產生熱水。這意味著打開龍頭，接通洗碗機，或在洗衣機上啟動循環。它配有內置線圈，設計用於在需要時加熱水。
There are certain advantages of using a tankless water heater. One is that it is more energy-efficient since there is no standby heat loss. It can also provide you hot water on demand. But the problem with this type of water heater is that it can only give you a limited amount of hot water—約9.8加侖每分鍾。此外，安裝它的前期成本可能非常持久。
另一方麵，儲罐熱水器是最常用的和使用的熱水器類型。它配有絕緣罐，其中儲存熱水直至需要。用儲罐熱水器，你不必擔心耗盡熱水。It’s also cheaper and best suited for large households. But the main problem with this type of water heater is that it is not as energy efficient as the tankless water heater.
How to Choose the Right Water Heater Sizes
在市場上提供眾多尺寸的熱水器，您必須確定您的平均用水量，以便您可以為您確定合適的尺寸。此外，您必須記住確定熱水器尺寸的幾個關鍵因素。
Fuel Source
For one, take into consideration your fuel source. Would it be electricity, liquid propane or natural gas? Will the water heater be connected to the broiler? Determining the fuel source will help you in narrowing down your options and enable you to choose the right water heater size.
房子大小
Another consideration is the household size. Do you belong to a large household with more than 10 people? If so you would need a higher-capacity water heater so that multiple people can do tasks at the same time, whether it’s running the dishwasher, doing the laundry or taking a bath.
Or do you live with just a partner and one child? If so then you can settle for a water heater with a lower capacity. These are some of the scenarios that can guide you in determining the right size of a water heater for you.
Now, if you have 1-2 people in your home and you are opting for a storage-tank water heater, you can opt for a unit with at least a 30-gallon capacity. It’s recommended that you get a storage-tank water heater with at least 40 gallons if you live with two to three people.
For families with three to four people, you would be better off with a water heater that has a 50 gallons capacity for the electric model and 40-gallons for those that use natural gas or liquid propane.
Now, if you have a large family with six or more individuals, it is recommended that you opt for at least an electric model with an 80 gallons capacity. If you are opting for natural gas or liquid propane, then you should get one with a capacity of 50 gallons.
You must also remember or know that the sizes of storage tank water heaters are based on BTU input and capacity in gallons. Therefore, the more regularly you need hot water, the higher capacity and BTUs you’ll need for home consumption. Let’s say that that four people in your household would be taking 10-minute showers in an hour.
Therefore, you would be using about 40 gallons of hot water. If you get a storage-tank water heater with a lower capacity than 40 gallons, your tank would be emptied with the third or fourth person not finishing his or her shower. In short, you must take into consideration the daily routine of your household members when selecting the tank size.
Flow Rate and Temperature Rise
但是去無水公司怎麼樣？由於無罐熱水器不儲存水，因此您不必擔心容量尺寸。但是有兩個因素，你必須注意流量和溫度升高。
In determining the water heater flow rate, you should add up all the flow rates of the appliances you would likely be using at the same time. Then subtract the incoming temperature from the outgoing water temperature to determine the necessary temperature rise.
Let’s say that the incoming temperature is 50 degrees Fahrenheit and the desired outgoing temperature is 50 degrees, then you must get a tankless water heater that has a temperature rise of 50 degrees.
Using this temperature rise, below are the sizes you’d need for a tankless unit:
- 同時使用的至少3.5 gpm為1到2個夾具
- At least 5 GPM for 2 to 3 fixtures used at the same time
- 在同一時間使用至少7gpm 3至4個夾具
結論
如果你住在寒冷的氣候國家，熱水器是一個必須擁有的。有兩種類型的熱水器儲存和無罐。儲存熱水器的大小將取決於將使用加熱器的人數。另一方麵，您需要考慮無油桶熱水器的溫度升高和流速，以確定為您家的合適的熱量。
