Our take on the Side Connections Electric Tankless On Demand Hot Water Heater - 240V | 11kW

This is a 240V, 11kW electric tankless water heater with side-mounted water connections. It heats water on demand and holds the set temperature within about 1°F, so it suits a single bathroom, a small sink or an office break room rather than a whole house. The alloy housing and a heating element kept out of the water path are meant to cut scale and corrosion. Against gas and larger electric tankless units it is compact and simple, but its 46-amp draw needs a 50-amp double-pole breaker and 6AWG wiring, which limits it to point-of-use and low-flow jobs. Buyers rate it highly, though the sample of ratings is small.

Best forA single bathroom or small sinkPoint-of-use installs near the tapOffice break rooms and low-flow fixturesTight spaces with no room for a tank
Pros
  • Holds temperature within about 1°F
  • Compact wall-mount design with no tank
  • Element isolated from the water tube to resist scale
  • Self-modulating, so it draws power only while heating
  • Overheat protection and auto shutoff when water stops
Cons
  • 11kW covers only one fixture or low-flow use
  • Needs a 50-amp double-pole breaker and 6AWG wire
  • No tank means no hot water during a power outage
  • Installation is a job for a licensed electrician

About the Side Connections Electric Tankless On Demand Hot Water Heater - 240V | 11kW

This is an electric tankless water heater that heats water on demand. It has no storage tank and mounts on the wall, so it takes up little space. It senses water temperature and flow rate and holds the water within 1°F of the selected temperature.

The housing and water ports are alloy metal. The heating element is separated from the water tube, which reduces scale, corrosion and mineral buildup on the element. Self-modulating power control uses only the energy needed to heat the water, and the unit is rated 99% efficient.

It has overheating protection and stops heating automatically when it detects no water. It is ETL certified. It suits point-of-use and low-flow applications such as a bathroom, a small sink or an office break room.

Questions and answers

Will it run a whole house?
No. At 11kW it is built for one bathroom, a small sink or another low-flow point of use. A whole house needs a much larger unit.
What breaker and wire does it need?
A 50-amp double-pole breaker and 6AWG wire on a 240V circuit. It draws up to 46 amps at full power.
What are the water connections?
1/2-inch NPT male ports on the side of the unit.
Does it work with a standard shower?
Only at low flow. A full-flow shower can outrun 11kW, especially in cold incoming water.
What happens when the water stops?
Heating stops automatically when no water flow is detected, and overheat protection shuts it down if it gets too hot.
Does it need a tank or a vent?
No tank and no venting. It mounts on the wall and heats water as it passes through.
