Overall, investing in a gas tankless hot water heater can provide energy savings and lower utility bills over time, and taking advantage of available rebates and incentives can make this upgrade even more cost-effective.
How do gas tankless hot water heaters compare to traditional tank-style heaters?
Gas tankless hot water heaters and traditional tank-style heaters have a few key differences in how they operate and perform.
First and foremost, tankless heaters do not store hot water in a tank like traditional heaters do. Instead, they heat water on demand as it flows through the unit. This means you never run out of hot water, but you also may not get the same consistent temperature throughout your shower if hot water is being used elsewhere in the house at the same time.
Another difference is in energy efficiency. Tankless heaters are generally more energy efficient than tank-style heaters because they only heat water when it is needed. Traditional heaters have to constantly keep a large tank of water hot, even if you're not using it, which can waste energy.
However, tankless heaters can be more expensive upfront than traditional heaters. They also may require more maintenance, such as regular descaling to prevent mineral buildup in the unit.
Overall, the decision between a gas tankless hot water heater and a traditional tank-style heater will depend on your specific needs and priorities. If you want an energy-efficient and space-saving option, a tankless heater may be the better choice. But if you have a large household with high hot water demand, a traditional tank-style heater may be more practical.
How much maintenance is required for a gas tankless hot water heater?
Gas tankless hot water heaters generally require less maintenance compared to traditional tank water heaters. However, some basic maintenance is still necessary to ensure the efficient operation and longevity of the unit.
The primary maintenance task is to regularly clean the unit's filter to remove any debris or buildup that may have accumulated. This can typically be done by removing the filter, rinsing it with water, and reinserting it. The frequency of filter cleaning will depend on the manufacturer's recommendations, but it's typically recommended to clean it every 6-12 months.
Occasionally, the unit's heat exchanger may also need to be flushed to remove any mineral buildup that can affect the heater's performance. This should be done by a professional plumber or HVAC technician.
It's also important to have the unit professionally inspected and serviced annually to ensure all components are functioning properly and to catch any potential issues before they become major problems.
