The Stiebel Eltron DHC is an electric tankless heater that runs on 120 volts of power. Compact and light, the DHC promises to save up to 50% power consumption compared to storage type heaters. It generates hot water almost instantly so you don’t have to sit around in the shower waiting until the water gets warm enough to use. It also comes with a scald-guard thermostat, which ensures that the water is always at the right temperature for showering. This is one neat feature that we loved the most simply because it offers more control in terms of adjusting the temperature of the water.
The DHC is designed to be installed at the point of use. This means the water heater will not be able to heat water all around the home. It gets the water hot via a copper heating coil, which we found durable enough to last years of use. A flow switch helps maintain even heating while the manual reset switch allows you to control the water temps even more. There’s a flow reducer switch that you can use if you’d like to limit the volume of water you use when you shower. Although this product is designed for commercial and office use, we think the DHC is best for home use.
As for the downside, this water tank – though powered by electricity – does not come with an electric plug. Unless you are a handyman, you’ll have to hire someone to install the heater for you. Some users say the heater does not generate hot water, but warm water at best.
