Domestic Hot Water Heating

Gas hot water heaters are efficient and effective. You now have the choice of traditional or tankless hot water systems. We would like to provide you with some information to help in the decision making process of your new water heater system.

Tankless Water Heaters

Tankless water heaters are compact heating units that provide hot water as it is needed, and do no store hot water like traditional tank-type water heaters. When a hot water tap is turned on, water enters the tankless water heater. A sensor detects the water flow, and activates an electric or gas heating device, which quickly raises the water temperature to a preset level. When water flow stops, the heating element shuts off. Thermostatically-controlled tankless water heaters vary their output temperature according to water flow rate and inlet water temperature.

Enjoy up to 40% energy savings, endless hot water, and significant space savings.

Unlike traditional storage tank water heaters, tankless water heaters do not store a reservoir of hotwater. As a result, standby losses are reduced, which makes them an energy-efficient alternative to traditional water heating. When water flow is detected, they begin heating water, making them highly efficient and cost effective. When the demand for water ceases, they shut down and use no energy.

There will always be hot water. Endless hot water - for bathing, cooking, dishes, laundry, and all the other countless ways hot water enriches our lives.

Tankless water heaters consume a fraction of the space consumed by a tank heater. They can be mounted inside or outside.

Because tankless heaters do not store water, they are less subject to corrosion than tank-type heaters. As a result, their expected equipment life is possibly longer - more than 20 years, compared with 10 - 15 years for traditional heaters. Also, because they are not heating 40 - 50 gallons of water 24 hours a day, tankless water heaters are less susceptible to leakage than tank-type water heaters.

Conventional Storage Type Water Heaters

Conventional storage water heaters remain the most popular type of water heating system for the home. A single-family storage water heater offers a ready reservoir from 20 to 80 gallons of hot water. It operates by releasing hot water from the top of the tank when you turn on the hot water tap. To replace that hot water, cold water enters the bottom of the tank, ensuring that the tank is always full.

Conventional storage water heater fuel sources include natural gas, propane, fuel oil, and electricity. Natural gas and propane water heaters basically operate the same. A gas burner under the tank heats the water. A thermostat opens the gas valve as the water temperature falls. The valve closes when the temperature rises to the thermostat's set point. Oil-fired water heaters operate similarly, but they have power burners that mix oil and air in a vaporizing mist, ignited by an electric spark. Electric water heaters have one or two electric elements, each with its own thermostat. With two electric elements, a standby element at the bottom of the tank maintains the minimum thermostat setting while the upper demand element provides hot water recovery when demand heightens.

Because water is constantly heated in the tank, energy can be wasted even when a hot water tap isn't running. This is called standby heat loss. Only tankless water heaters such as demand water heaters and tankless coil water heatersavoid standby heat losses. However, you can find some storage water heater models with heavily insulated tanks, which significantly reduce standby heat losses, lowering annual operating costs. Look for models with tanks that have a thermal resistance (R-Value) of R-12 to R-25.

Gas and oil water heaters also have venting-related energy losses. Two types of water heaters a fan-assisted gas water heater and an atmospheric sealed-combustion water heater reduce these losses. The fan-assisted gas water heater uses a draft-induced fan that regulates the air that passes through the burner, which minimizes the amount of excess air during combustion, increasing efficiency. The atmospheric sealed-combustion water heater uses a combustion and venting system that is totally sealed from the house.
