Hello. What is the minimum flow required to switch this heating unit on? I have not been able to find this spec. Thanks.

I have to open my faucets all the way to start it. There is a small amount of water in the unit that gets extremely hot all at once and heats the water exiting the unit. When there is enough water exiting the unit to ensure safe operation, it will turn on and do what it was designed to do. If the incoming water is very cold, or the faucet you want to use is far from the unit, you may need to turn it to maximum power (5).

I measured .75gpm on the lowest flow that activates the unit. Ours is on the highest setting.

My unit is about 6 feet from my shower head. Unit turns on at about .5 gal. Per min.

The hot water that it outputs depends on the hot water that is needed. If one is taking a shower at 2 GPM, he will get 2 GPM out of the water heater, as long as the maximal heating capacity is not reached. The hotter the input water, the higher the maximum flow rate will be (up to the capacity of the pipes). The question is linked with the minimal flow rate of 0.26 GPM this unit has. Below this, the water heater shuts off. 1. What happens if I need 1 GPM at 120F and that my input is at 115F. Will it shut off or will it output water above 120F ? 2. Shouldn't the minimal flow rate be expressed based on the temperature rise (0.26GPM at 50 degrees rise, 0.52 GPM at 25 degrees rise, 2.6 GPM at 5 degrees rise) ?

this unit requires 240 volts, which requires running a dedicated circuit from electrical panel and a line voltage thermostat to control temperature. I strongly recommend that this only be installed by a qualified electrician.

The product is rated to switch 120/240VAC up to 22A. So, it can handle a fairly large load. I would, however, NOT generally recommend switching an A/C at the power supply side, as it could cause stress to the appliance. Use the built-in thermostat instead or refer to the manufacturer's instructions.

Hi talked to tech guy at Liberty they recommended 2" for best flow but suppose min. Would be 1.5" ...for code think they will require 2" upc Hope that helps

Yes u can wire it with a switch, but i had it wired into the box. The thermo on the heater is adjustable and can be shut off easily. In my opinion having 2 switches would be stupid. No idea on length of time but i can say it will heat an 800 square foot room from freezing temps to about 65 in a day. If u are planning on it being quick, either turn it on the night before, or have a smaller area. It is effecient and quiet, but does not put out as much heat as a salamander.

One switch, but the heat is maybe a 'little' lower along w/the air flow on low.

It recommended that it be a 20 amp. As to whether that has to be dedicated or not, I don't know, but I know that on my breaker, it is on its own circuit. I think the heater takes a fair amount of energy so it should be on its own.

I don't know what that means. To activate, this unit requires a minimum flow rate of 0.15 gpm. The only effect of this for us has been on our dishwasher, which fortunately, has an internal heater. Otherwise, we have noticed no performance difference between this heater and our previous, tanked, heater. Except, of course, that we never run out of hot water anymore and our gas bill has gone down by about 10%.

Just one switch.....turn it on, regulate how much heat you want, turn it off......I have a small bathroom and if I wait 15-20 minutes, it is great versus a cold tile floor! Hoo RAH!

Susan,I just installed my today.I wish I could have a pic to show you. Since I bought this to replace an old Intertherm heater.I had to purchase an adapter plate to avoid re frame my wall.This unit has the fan case of about 3" deep this case have to go inside your frame.The pic that you see on Amazon will be on top of your wall. It is just a cover of the actual fan and heating. I will pass on to you the e-mail of the Steve. he is the Cadet technical help. He was very helpful to me prior I purchase It. selhart@cadetheat.comIt is a great unit. You will like It. Good luck.They make It in 110 volts and 220 volts.I got the 110 v because that is what I had before. Susan,I just installed my today.I wish I could have a pic to show you.

According the the spec sheet this units runs 8.6 amps when cooling and 11.1 when heating. I ran its own 20 amp 12awg line and it works perfect.

Most systems must be installed by a licensed contractor and have a permit to collect the rebates. This insures that the inspector has verified that the system was installed correctly. If you must have a 14 SEER, then getting a 15 SEER would be best to make sure that you at least meet the standards. 16 SEER will meet those standards, and save even more energy, yet is much more expensive. Sometimes a 14 SEER system will not meet the 14 SEER rating due to smaller air ducts, or other problems. Also how many square feet are you trying to heat and cool? What state are you in? This will help verify if the system is sized properly. Also do you plan on installing back up heater? If so what size? I disconnected my 20 KW electric heater when installing my 4 ton heat pump. For back up heat, I will use one section of the 20 KW, and disconnected 1/2 of that, giving me a primary 5 KW electric heat back up. Then have a 10 minute time delay, so that the other 10 KW heater contactor will energize to provide another 34,000 Btu's of heat when it is calling for heat more than 10 minutes. I could have wired the 5 KW heater to run at the same time as the heat pump is in defrost, however I decided I would rather have 5-7 minutes of cold air and save the energy. My 4 ton heat pump makes about 48,000 BtuH of heating, at 55F outside air temp, then will defrost for about 2-3 minutes per hour (at 55F outside air temp). During defrost, it reverses to cooling cycle, and will blow out cold air (if it is 70F inside the home, it will blow out 50F air for a few minutes). By running a 5 KW electric heater ($0.50 to $0.75 per hour - depending on local electric costs) this can warm the air to about 65F while in defrost. I am just cheap and want to save the money! If my family complains to much, I might have to run the 5 KW heater during defrost.

Sorry, I'm afraid I don't have the answer. I ordered this part for a family member who gave me the info for the order from a heating professional ( and I have no idea who that was) and he installed it. Sorry again.

I don't believe the GPM is sufficient enough for the water heater to turn on! check the manufacturers minimum requirements for GPM (gallons per minutes)

request a new inspector, he dont know what he is talking about!!! i have this unit in a 3 bed room house with 2 adults living here showering everyday, washing machine, dish washer, 2 full bathrooms and 2 grandchildren here 5 days a week.as long as you have 2 gallon a minute shower heads everything will be just fine. i have had this installed for 5 months now with great electric use savings and NO complaints about the hot water production at all, the unit works very well for us here in breckinridge county kentucky 40152 i have, like the directions say 1/2 inch pipe. 3 foot on each side of the unit. and my water flow is 5-6 gallons a minute

The only on - off switch is built in the unit. When you run water it heats when off it stops ....... Look at the speck sheet !!!!!!!
