What are some other benefits of switching to an electric tankless water heater?

Lower energy costs: Electric units use less gas or oil than natural gas and propane models which means they save you money in the long run.

Less maintenance: Since these units don’t store enough heat like traditional tanks do, there’s no need for routine draining or cleaning out sediment that can build up over time. They’re typically more efficient too since they produce only as much power as needed at any given moment – so there’s less excess energy and heat loss.

Space efficiency: Tankless models are smaller in size, so they’re a great option if you have limited space at your home or apartment.

Quiet operations: You won’t hear any loud noises or rattling with electric units like you may with gas ones – which can be really helpful for those who live close to bedrooms during the night time hours when families tend to sleep more deeply.

They use less energy: The best electric tankless water heaters are up to 80% more efficient than the best gas units, in some cases.

Less maintenance: Since they don’t need any filters or other parts changed out like you would with a traditional heating system, there’s much less upkeep required. This can help save money on service costs and even potential replacements down the road since these systems just work so well.

They work better in cold weather: Electric tankless water heaters have an “on demand” system that will only turn on when it needs to warm up the incoming tap water. This makes them perfect for homes with pipes and radiators that freeze during colder months because there’s no need to constantly run hot water through those lines.

It’s best as a whole house heater if you live in areas where winters are extremely cold or summers exceptionally hot – instead of having your energy go unused all winter long (and costing more than necessary), electric tankless systems provide instant access to hot water.

They are more efficient: Tankless units work by constantly pushing fresh, cold water through a heating element that never runs out of energy. This means they can heat up the incoming supply of tap water in as little as three seconds – and don’t need to use any power for standby purposes because there’s no tank sitting around waiting to be heated up when you want it.

Electric tanks have an infinite lifespan: Unlike gas or propane systems, which eventually run out if fuel, electric tankless models will last forever so long as you keep them plugged into their power source (and maintain proper maintenance). With this nonstop supply of electricity these devices won’t “run down,” giving off unpleasant odors or emitting heat.

Lower operating costs: Tankless water heaters are more expensive to purchase, but they save money on your utility bill in the long run because of their “instantaneous” heating system and lack of a tank. The average electric tankless unit can cut up to 30% from your monthly energy consumption by just replacing an old gas water heater with one that’s finely tuned for efficiency.

Quiet operation: In contrast with standard power tanks like those found in conventional models, these units don’t have any moving parts – which means no loud humming when you want silence while trying to sleep or concentrate on something else!
