Lochinvar electric water heater

Lochinvar offers two series of electric units for hot water production; small, point-of-use electric heaters, with the sizes from 2 to 30 gallons, and large, high efficiency residential electric models for the whole-house application.

Point-of-use electric water heaters are known as Junior Electric group, designed in five different tank sizes; 2, 6, 12, 20 and 30-gallon capacity.

The other group covers models with the capacities from 30 to 120 gallons, which are designed in tall and short sizes, where some of them are energy efficient.

Features of the point-of-use models (POU)

Lochinvar electric water heaters for point of service applications are designed for small hot water delivery and installation in the close proximity of the water fixture.

POU models are equipped with the durable fused glass lining to provide longer tank life, and together with the magnesium anode rod are protecting the steel tank from aggressive water action, corrosion and potential leak and damages.

Quality engineering and design allow high thermal efficiency and first-hour rating, and reduced standby heat loss.

For easier and precise temperature control, the thermostat on Lochinvar water heaters is adjustable. Before adjusting the thermostat, the power has to be turned off, cover removed and use the screwdriver to adjust the temperature. As all the Lochinvar water heaters are shipped with the pre-set temperature of 120 F, it can be noted that a simple change of the temperature of hot water is actually inconvenient.

In order to use it for different applications, Junior Electric heaters are equipped with a variety of heating elements, voltages, and wiring. The minimum power used is 1500 W for 2-gallon model JRC002E which works on 120 V, the maximum wattage for 6 and 12-gallon models is 3000 W and for 19 and 30-gallon models is 6000 W.

As the energy factor is available only for capacities of 30 gallons and up, EF is provided for only one model, and it is 0.93. This is the largest point-of-use model and its recovery rate is 62 GPH with the 40 F temperature rise.

Hot and cold water connections are standard 3/4" and for 6 and 12-gallon models, they are found on the side of the heater with an alternative option, on the top. The temperature and pressure relief valve is included, and it is required as the safety element.

Lochinvar offers a standard 6-year warranty on the heater’s tank, while the 10-year extended warranty has to be purchased.

Features of the high-efficiency models

Lochinvar manufacturer designs the high-efficiency residential water heaters from 30 gallons and up to the 120-gallon tank capacities, and in two sizes: tall and short.

Short models are available in sizes from 30 to 50-gallon tanks.

As the previous series from Lochinvar, high-efficiency electric models are equipped with the thick NON-CFC foam insulation to protect the unit from significant heat loss through the tank wall. The factory installed heat traps are added to reduce the heat loss through the piping.

High-efficiency Lochinvar water heaters are using the screw-in, immersion type heating elements, upper and lower, which are designed for easy installation and longer life, even in hard water.

To control the temperature of hot water, use the adjustable thermostat which is a standard component of the Lochinvar water heaters. This is what allows you to change the temperature of hot water, and the automatic overheat safety limit allows safe operation of the unit.

The inner surface of the metal tank is protected with the fused glass lining and sacrificial anode, and even with such a protection, the heater tank is subjected to corrosion. This is why Lochinvar provides six or ten-year limited warranty on water heaters.

All the water connections are using the standard 3/4" size, brass drain valve at the bottom of the heater so you can drain the water when needed. Water inlet, hot water outlet, and T&P valve are all located on the top of the heater, while the side connection for T&P is optional.

Summary

If you have decided to choose one of the Lochinvar electric water heaters, you won't mistake choosing either type, as long as you have selected the correct size. They are much cheaper than gas and easier to install. They do not need a gas line and venting system making them safer. If the demand for hot water is low, or house is small, go with the water heater with the smaller capacity (POU) models, while for larger homes, go with the capacity of 50-gal and up.

All the electric units meet or exceed the NAECA and ASHRAE energy efficiency standards. They are all triple-tested during fabrication so you are getting the water heater that meets the highest standards, quality, and performance.
