Pros And Cons Of Brentwood Tankless Water Heater
Hot water is one of those things we just take for granted. You turn on the shower and it to be hot, until it isn’t. And then you have absolutely no idea what to do. So, you call the plumber, expecting a minor fix, only to be told that it’s time for a new hot water heater.
While you may opt to purchase the standard conventional storage tank type heater, before rushing to do so, consider purchasing one of the newer Brentwood tankless water heaters (also known as an instantaneous or demand water heater). Before rushing out to make your purchase, however, consult with your plumber about your specific circumstances to determine if a Brentwood tankless heater is best for you.
Tankless Water Heater Pros:
While a conventional heater with a storage tank heats water continuously (24 hours a day, 7 days a week) to maintain a certain temperature, a Brentwood tankless water heater only heats water when needed (without storage), thus resulting in substantial energy savings.
Constant Supply of Hot Water.
Brentwood tankless water heaters have an electric or gas heating mechanism activated by the water flow, which, once activated, provide a continuous supply of hot water.
Operational Cost Savings.
Due to their increased efficiency, electric tankless water heaters usually cost 10 percent to 20 percent less to operate per year than the comparable tank type heaters, while gas tankless models usually reduce cost by 20 percent to 40 percent per year.
Higher “life expectancy.”
Since hot water is not stored, Brentwood tankless water heaters are able to handle hard water minerals and sediments better than tank type heaters. Thus, they are less subject to corrosion. As a result, the “life expectancy” of a Brentwood tankless model is approximately 20 years, as opposed to a “life expectancy” of between 10 and 15 years for a model with a tank.
Unlike conventional storage tank water heaters, which, as a result of their large storage tanks, are bulky and take up space, tankless – especially electric – units are compact in size.
Tankless Water Heater Cons:
Flow rate is limited.
While a Brentwood tankless model can provide unlimited hot water, this is only true as long as it does not exceed its maximum flow rate, with the maximum flow rate at a desired temperature being determined by the capacity of the heater.
While gas tankless models typically have larger capacities than electric tankless water heaters, regardless of whether it operates by gas or electricity, where simultaneous, multiple hot water use is common, one Brentwood tankless heater in a house may not be sufficient to produce enough hot water.
Up front costs are high.
Gas and electric tankless units are much more expensive than their storage tank counterparts (except when being compared to the high efficiency storage tank systems). Moreover, installation costs are up to four times higher than tank type heaters.
For electric tankless water heaters, additional wiring, multiple electric circuits and/or a heater cable may be required, and for gas tankless models, gas pipes may need to be upgraded and a new ventilation system may need to be installed.
When considering whether to purchase a tankless unit, it is important to consult a licensed plumber to determine the scope of work needed.
Longer wait time.
Since the Brentwood tankless heater does not begin to heat water until the tap is turned on, it takes longer for the flow to begin than with a storage tank type heater. As a result, some water may be wasted while the user is waiting for it to heat up.
