    Why upgrade to a tankless water heater?


    By heating water as it’s needed instead of storing it in a tank, tankless systems use far less energy than standard water heaters. Those energy savings can really add up over time!

    Endless Hot Water

    Tankless water heaters heat water as it’s needed at the tap by running cold water through a series of heating elements. In this way, they can heat as much as water that is needed for the home.


    With some care and maintenance, your tankless water heater will last about twice as long as a traditional water heater. That’s something to consider when weighting the upfront cost of these systems!

    No Risk Of Flooding

    Unlike standard water heaters, there’s no tank or stored water. This eliminates the risk of a tank burst and a flooded garage, basement, or utility closet. It’s one less thing to worry about!

    Quick Hot Water

    Tankless water heaters can go in more places than traditional systems. This means they can be mounted in master bathrooms to provide near-instantaneous hot water to our shower. No more waiting!


    Tankless water heaters are wall-mounted, which saves on space and allows them to easily fit into more places in the home. They don’t need a huge physical footprint like a standard water heater.

    How much do these systems cost?

    We install several different types of tankless water heaters, so you’ll need to contact us to get an estimate. Generally speaking, tankless systems are about twice the cost of a standard water heater. However, as explained in our answer to the next question, these systems can make up for this difference over their lifespan through energy savings. They’re still a good investment for any home here in Buffalo!

    Is a tankless water heater a good investment?

    As mentioned in our answer to the previous question, demand-type systems are generally twice as expensive to install as a standard water heater. Don’t write them off just yet, though. If you’re planning on staying in your home for the foreseeable future, tankless water heater installation here in Buffalo might still make a good deal of sense. Because tankless water heaters are more energy-efficient, they’ll eventually pay off the difference in upfront costs. Plus, they’re convenient!

    What is a “demand-type” water heater?

    It’s just an alternate name used for tankless water heaters. The “demand-type” in the name refers to how tankless water heaters can create hot water on-demand, instead of storing it in a tank like a standard (or “traditional”) water heater. This allows these systems to meet endless demand for hot water instead of running out of it on busy mornings! To learn more about tankless water heater maintenance here in Buffalo, call us today.

    Is there a difference between electric and gas systems?

    As with furnaces and other appliances, electric systems are, from a pure physics standpoint, more energy-efficient. They use less overall energy to convert power to heat. However, that’s not the end of the story. Because natural gas is cheaper than electricity, natural gas water heaters tend to be cheaper to run, overall. In truth, either system can be a good fit for your home. But, if you have existing natural gas connections, a gas water heater just makes the most sense.
