EcoSmart ECO 27: What you need to know
The ECO 27 tankless water heater is a compact model, measuring 18 x 17 x 3.75 inches and weighing 13.75 pounds. It will therefore fit in tight spaces, but is still not as small as the Chronomite SR-20L/240 (opens in new tab), if room really is at a premium. What this water heater also has is a sleek, contemporary design and a low-maintenance copper and stainless steel construction for longevity and simple replacement.
The ECO 27 requires a 240-volt electrical system and has thermal auto protection to prevent overheating and overloading. This model also has three 9-kilowatt elements and an amperage draw of 112.5. For correct installation and operation, you need 0.75-inch NPT pipe fittings. EcoSmart also includes a lifetime warranty on the water heater’s electronics, exchanger, and elements, which is outstanding. However, to qualify for warranty coverage you'll need to employ a professional to install it - also note that only the cost of the heater is covered, and not any labor.
EcoSmart ECO 27: Energy efficiency
The ECO 27 comes with a digital control panel that allows you to adjust the temperature of the water output in 1-degree increments, giving you precise control. With a maximum flow rate of 6.5 GPM, it is also capable of running up to four showers and a sink at the same time.
However, the flow rate and energy efficiency the ECO 27 achieves will depend on the climate in which you live and the temperature at which water enters the heater. The warmer the water at the inlet, the more energy-efficient the model and the higher the flow rate, as it can reach the desired temperature faster. While it doesn't have an Energy Star certification, the ECO 27 promises 99.8 percent energy efficiency.
The ECO 27 is also self-modulating, which means that this electric tankless water heater adjusts the amount of energy it draws based on how much water you're using and the temperature at which it is set. This feature ensures the temperature of the water meets your needs without wasting excessive energy.
EcoSmart ECO 27: Features
The EcoSmart ECO 27 is a great space saving option compared to a water heater that requires a huge tank and takes up loads of room. Tankless water heaters obviously don't have a tank to keep hot water in, and instead, models including the EcoSmart ECO 27, heat water as it passes through the machine.
What's more, the EcoSmart ECO 27 is only on when you need hot water, it doesn't waste energy by keeping water hot when you're not using it.
The components in this electric tankless water heater are made with copper and stainless steel to ensure they last as long as possible.
