| DHC 3-1 low volume single sink 110V tankless water heaters |
|
|
This point of use tankless water heater is the only option when you are running at 110V or 120V. It comes with a pressure 1/2 GPM compensating flow reducer/aerators that fits on most faucets. Trying to get more flow from this low voltage is not possible and would just lead to disappointment.
If you are having difficulty determining how much of a flow you get…. This 1/2 GPM is the recommend flow rate for a public lavatory and would fill the average bath tub in about 1.1/4 hours.
But that said, this is the simplest option if you are needing to replace a currently cold faucet with some nice running hot water and tankless is cheaper to run and cheaper to install than a tank type unit.

| DHC 6-2 medium volume single sink 220V tankless hot water heaters |
|
|
This is a more versatile point of use tankless hot water heater than the smaller 3-1 unit, and is designed for use at one sink location. It requires a 220V connection, but will work out cheaper to install than a tank type system.
Output flow is not restricted on this hot water heater. It has a theoretical working range of 1/2 GPM to 2 GPM but a more practical range is 1/2 GPM to 1 gallon per minute. You get an 82 degree temperature rise in the water at 1/2 GPM, 41 degree rise at 1 GPM but would shrink to just 20 degrees if you turn on a 2 GPM faucet to full speed. 1 GPM is double the recommended flow rate of a public lavatory.
Flow rate not recommended for a kitchen sink.

| DHC 10-2 medium to high volume single sink 220V tankless water heaters |
|

This is the most powerful model in the DHC range. Designed for use at one sink location, but this model provides a much better flow of hot water. It requires a 220V connection, but will work out cheaper to install than a tank type system.
Output flow is not restricted on this hot water heater. It has a theoretical working range of 1 GPM to 2 GPM but a more practical range is 1 GPM to 1.1/2 gallon per minute. You get an 83 degree temperature rise in the water at 0.79 GPM, 63 degree rise at 1 GPM but would shrink to just 33 degrees if you turn on a 2 GPM faucet to full speed. 1 GPM is double the recommended flow rate of a public lavatory.
Flow rate is about the minimum recommended for a kitchen sink.
