Tankless Water Heater Basics
Tuesday, December 8, 2009
If you are remodeling your Jacksonville home or thinking about replacing a hot water heater, you might be considering tankless or instant water heating. There are many good reasons to consider either a whole-house tankless water heating system or several strategically placed “booster” tankless hot water heating units. To help you with your decision, here are some of the basic facts about tankless water heaters.
Whole-house tankless units can range in price from $199 to $4000.
Storage water heaters usually last 10 to 15 years; tankless units last 20 years or more.
Jacksonville tankless water heaters are 8% to 50% more energy-efficient depending on the amount of hot water used in a day and placement of the unit(s).
Tankless heaters can reduce your water heating cost by as much as 60%.
Tankless water heaters heat 2-5 gallons of water per minute.
There are two main types of tankless water heating units: electric powered and gas-fired. Gas-fired units are able to generate a higher flow than electric units.
Tankless water heaters produce hot water by heating an element which heats the water as it passes across the element on its way to the tap. Because no water is actually stored in a tank and constantly heated to keep it at a standard temperature a significant energy savings is achieved by changing to tankless water heaters.
Tankless water heaters do not cause leaks and flooding due to cracking of the storage tank or a leak in a key pipe because no water is being stored.
Because tankless heaters only process 2 to 5 gallons of water per minute, they can reach capacity at times of heavy use, such as running the dishwasher and the washing machine at the same time or running an appliance while showering. This can be avoided by installing a booster unit or by installing separate units for certain appliances.
Tankless water heaters are small and self-contained. They are ideal for such uses as:
- Garage sink
- Gardening or potting shed
- Outdoor barbeque or cooking area
- Pool Shower
- Pool House
- Garage or workshop bathroom
- Hot Tub
- Soaking Bathtubs
- Auxiliary bathrooms
- Second or third bathrooms some distance from the hot water heater
- Pet bathing area
- Hobby room
- Guest bathroom
- Guest house
- Vacation house
- Beach house exterior shower
Tankless water heaters make a great deal of sense in low-use areas of your Jacksonville home or detached structures. They also make a great deal of sense in structures that are not monitored constantly, such as a vacation house, in which a broken storage tank could cause a great deal of damage.
