Residential Water Heaters

Residential water heaters provide one basic, but essential service – they heat water! In the Baltimore – Annapolis metropolitan area the average life of a water heater tank is 11 years. When the tank begins to leak the water heater must be replaced. Until then parts on the water heater can be replaced. But just because your water heater is not leaking does not mean you shouldn’t replace it. Water heaters today are much more energy-efficient than their predecessors. Not only that, but over the life of the water heater it gradually declines in efficiency. An energy inefficient water heater could be costing you more to keep than a new energy efficient water heater would cost to install and operate.

Electric Residential Water Heaters

Select Electric Water Heater

Select Electric Water Heater

Electric residential water heaters typically come in 30, 40, 50, 65* and 80* gallon nominal sizes and generally require a 240 volt electrical circuit. Most make use of two heating elements which are each controlled by an individual thermostat. When the water heater begins to heat the water, first the upper element comes on and when it reaches the set temperature the thermostat turns that element off and then the lower thermostat triggers the lower element to heat the remaining water. They never heat at the same time. The water heater also has a dip tube that allows cold water to enter from the bottom of the water heater and not cool the hot water in the top of the tank as it enters.

*65 and 80 gallon electric water heater sizes are no longer available as of April 16, 2015 in order to comply with NAECA III guidelines.


Electric Heat Pump (Hybrid) Residential Water Heaters

State Premier Hybrid Electric Heat Pump Heater

State Premier Hybrid Electric Heat Pump Water Heater,A new, more energy-efficient type of electric water heater is a heat pump or hybrid water heater. These water heaters use their heat pump to heat the water at a lower operating cost. They also make use of standard electric elements when necessary. Because the heat pump water heater draws energy from the ambient air, in order to function efficiently they require either a 750 cubic feet space or a 128 cubic feet space and the addition of a duct kit. Heat pump water heaters are available in 50, 65 and 80 gallon sizes and generally cost about three times more than their conventional electric water heater counterparts. There may be tax and energy company credits available.

Gas Residential Water Heaters

Select Atmospheric Vent Gas Water Heater

Select Atmospheric Vent Gas Water Heater

Residential natural gas water heaters and propane residential water heaters come in 30, 40, 50 and 75 gallon nominal sizes. The difference between these and the electric models is the gas burner at the bottom of the tank in lieu of electric elements. Gas water heaters also need a way to vent the exhaust fumes from your home. The most common method is to use an atmospheric vent making use of galvanized piping that connects to a chimney. Another method is to use a power vent water heater and PVC pipe to vent the gases typically through an outside wall. Still another method is to use a direct vent water heater that uses concentric vents to both bring fresh air in and allow exhaust gases to be expelled.

Tankless Residential Water Heaters

State Indoor Tankless Water Heater

State Tankless Water Heater

Electric tankless water heaters are designed according to the amount of hot water required at peak use times. The water heater has a series of heating elements that are activated based on the demand. As water demand increases more elements are activated. This is different from an electric tank water heater where the elements are never on at the same time. As a result, the electric tankless water heater requires a 240 Volt circuit for each element in the water heater so an electrician will also need to be involved in the project.

Gas tankless water heaters operate by heating the water as it passes through the natural gas or propane heat exchanger.


Solar Residential Water Heaters

Solar water heaters use the heat of the sun to heat water. We don’t install solar water heaters.
