Tankless Water Heater Flow Rate, Heaters, Flow Rates

If you want to buy a tankless water heater for your home, there are several aspects you should look out for. You need to choose the type of the water heater, which usually means either electric tankless heater or gas tankless heater. More importantly, you need to know what you need the tankless heater for. It is very important to know if you need it for a single appliance, for a kitchen or a bathroom or for the entire home. That’s why I’m going to tell you what flow rates require the most common type of appliances and I’ll give you some examples of the temperature rise of some tankless water heaters.

It is very important that you know, approximately, what flow rates the appliances in your home need, because then you can calculate the total flow rate you need and at what temperature rise. A lavatory fixture type needs a flow rate of 0.5 gallons per minute.

The dishwasher should be provided with a flow rate of 1 to 3 gallons per minute. A shower requires a flow rate of 1.5 to 3 gallons per minute. The kitchen sink needs a flow rate somewhere between 1 gallon per minute and 1.5 gallons per minute. The pastry sink should have a flow rate of 1.5-2.5 gallons per minute. A laundry sink needs the flow rate to be somewhere between 2.5 and 3 gallons per minute. The appliance that requires the highest flow rate is the bathtub, the flow rate is required is between 2 and 4 gallons per minute. Another reason why the flow rates are important is because the tankless water heater can raise the temperature of the water based on the flow rate. That means if the flow rate is low, the temperature is high and if the flow rate is high, the temperature is low.

The flow rates of tankless water heaters depend on the type of tankless water heaters. The flow rate of a point of use tankless water heater is somewhere between 1 and 2 gallons per minute. Multiple appliance tankless water heaters can have a flow rate of 3 to 5 gallons per minute. The whole house tankless water heaters can reach a flow rate of 8 gallons per minute or even more. Knowing all these facts will make choosing a tankless water heater very easy. So, do all the calculations before you decide what tankless water heater you buy.

Bathroom Remodelling Plan and Information in 2017

When putting together a plan for your bathroom remodel these are some of the things you need to take into consideration:

Shower Stall

Reserve at least 34 square inches for a shower enclosure. An enclosure 42 x 36-inches is even better to ensure sufficient elbow room. Ensure at least 30 inches of clearance in front of the shower stall.Install the shower head at a height that best accommodates all users. The showerhead height for a 5-foot, a 3-inch person, is 71 inches; for a 5-foot, 10-inch person, it’s 78 inches. To accommodate both people, use the average of the two measurements by adding them together and dividing by two. Other options include mounting two showerheads, installing a handheld sprayer, or buying a showerhead that can be adjusted for height.


Allow 36 x 36 inches of clearance in front of the toilet or bidet, and reserve 16 inches from the center of the fixture to an adjacent wall or other fixture.

The toilet enclosure should measure at least 36 inches wide and 66 inches deep. Learn more about best toilets here.
