Instantaneous Water Heaters
Use Instant Water Heaters to Supply Hot Water to Your Remote Bathroom
Instantaneous or tankless water heaters provide hot water only as it is needed. Another name for the instantaneous heaters is demand.
These systems heat water directly without the use of a storage tank. Cold water flows to the instantaneous system to be heated at the moment the tap is turned on, thus avoiding the standby heat losses associated with storage water heaters.
The choice is yours, whether you want an electric or gas-fired tankless water heater, for your outdoor sink, hot tub, pool house or remote bathroom. If you choose an electric, you will need to consider the electrical requirements. Or, if you are more impressed with gas-fired, you will need to take in consideration the gas type ( natural or propane ) and venting requirements.
Instant Water Heating Drawbacks
These tankless heaters call for a bigger power supply or larger gas lines and vents since the heating elements and gas requirements for these units are much larger than those for storage water heaters.
Since energy is not required for storing the water in the tankless water heaters, they are considered to be energy efficient. But, just a reminder that if the pilot light is left on a gas-powered tankless heater, it will use energy. Another disadvantage is finding a service man and parts if your instantaneous water heater happens to break down, especially if you live a small town.
How Much Instant Hot Water do You Need?
Instantaneous water heaters are very convenient for remote bathrooms, small apartments and even hotel rooms. But, since they limit the amount of hot water that can be supplied, these demand heaters wouldn’t allow you to do your normal everyday chores such as running the dishwasher and showering at the same time.
A few advantages of these tankless heaters are that they provide warm water immediately and they make great back-up systems for appliances that use a great deal of hot water such as washing machines and dishwashers.
If you do decide on using this type in your home, make sure it has modulating temperature control. If not, your water temperature will fluctuate and this will make your shower very uncomfortable. You may even want to consider installing two tankless systems if you have a large family.
Buying and Installation
There are several factors you should consider when deciding what type of Instantaneous water heater is right for your needs. One very important factor is knowing the flow rate of your fixtures. You should also consider how many faucets will require hot water and exactly where you need hot water.
Installing a tankless water heater may be a little more expensive than you planned. New plumbing, gas and electricity lines and flues and vents may be required. It may be best to consult with an electrician and plumber before any decisions are made final.
If you plan to make this a diy remodeling project, check with the manufacturer and local building code agency to guarantee proper installation.
Just keep this thought in mind — An instantaneous water heater will normally last twice as long as a conventional one. This, along with the energy efficiency and lower operating costs, makes it sound pretty incredible. Now, up for a hot shower?
