All About Gas Tankless Water Heaters

There are many things homeowners can do to update their home.
No matter how nice, big, or new, every homeowner has a wish list of things that want to change in their home.
For homes that use gas for some of their energy, getting a gas tankless water heater will save on energy and create lower bills each month.
Heating water in a tank is usually 30 percent of the average home's energy budget.
Switching to gas tankless heaters will save homeowners on these energy costs.
They use high power burners to quickly heat water as it runs through a heat exchanger.
Savings with a tankless heater is around $70-80 a year.
However, they initially are very expensive to purcesed and install.
Some experts estimate that it can take 22 years to break even.
This number really depends on where homeowners buy the heater from.
There are many independent tankless heater stores which can offer better deals so homeowners get a larger return on investment.
Initially, tankless heaters cost $800 to $1,150 to buy and install.
Traditional tank heaters cost $300 to $480 comparatively.
However, long-term cost savings make the first investment worthwhile.
When installing, tankless heaters need electrical outlets for the electronic regulation system along with upgraded gas pipes and a new ventilation system.
Tankless water heaters produce large amounts of hot water on command.
However, they do not instantaneously provide hot water.
Just like tank heaters, the water is cold at first until the hot water can get to the faucet in time.
There is a science behind this, as opposed to tank heaters which naturally feed in cold.
A tankless heater will send cold water first to gauge what kind of temperature is there.
The hot water may not feed if people just need a little bit of water, such as when shaving.
Since tankless heaters regulates by electric controls, if there is a power outage homeowners will lose hot water.
This problem also occurs in tank heaters.
Tankless units need more care than tank heaters.
To help reduce the amount of care needed, homeowners can get special valves installed and for all the pipes flushed out with vinegar.
Tankless heaters also needs servicing once a year by a qualified technician.
This is because a calcium buildup can cut the efficiency of the heater, along with restrict water flow and damage models.
If homeowners live in a hard water area (a rating above 11 grains per gallon), then a water softener is installed.
Warranties are made void if a water softener is not installed.
Traditional heaters will use between 30,000 and 50,000 BTU of natural gas or propane to heat the water each time the sitting water starts to lose its heat.
Tankless heaters need between 150,000 to 200,000 BTU to heat up water on demand.
These numbers turn some people off from buying a tankless heater.
These numbers seem bad, but homeowners need to realize how often traditional heaters need to be reheated during the day.
Even after insulation, they are constantly losing their heat.
The gas kicks on, heats it, turns off, then the process repeats.
Depending on how often homeowners need hot water, the tankless is a better choice.
