Tankless Water Heaters Explained: What Homeowners Need to Know Before Making the Switch

We’ve all been there, turning on the tap only to wait what feels like forever for the hot water to arrive, or having the hot water run out just when you need it most. These are the kinds of everyday annoyances that have led many homeowners to reconsider how they heat water in their homes. The solution for many? A tankless water heater. These compact, high-efficiency systems are becoming increasingly popular for their ability to deliver hot water on demand, save energy, and take up less space. But which is better, a tankless water heater or a tank in Kelowna?

To answer that, it’s helpful to understand how these systems actually work. A tankless water heater works by skipping the traditional storage approach altogether. Instead of storing and continuously reheating gallons of water in a tank, the tankless unit heats water only when you need it. When you open a hot water faucet, cold water flows through a heat exchanger, where it’s quickly heated by either a gas burner or electric element. This process provides instant hot water, without wasting energy keeping a supply warm all day.

The Benefits of Hot Water on Demand

The benefits are clear: tankless water heaters provide a virtually unlimited supply of hot water, making them perfect for large households or anyone who hates waiting their turn in the bathroom. Their wall-mounted design frees up floor space, making them a great fit for homes with smaller utility areas. Plus, with proper water heater maintenance, these systems can last up to 20 years, nearly double the lifespan of a traditional water heater.

However, there are pros and cons to consider. The most notable downside is the initial cost. A new tankless water heater and its installation are typically more expensive than a standard storage water heater. If you’re installing a gas tankless water heater, your home may also need upgrades to the gas line or venting system. And choosing the wrong size tankless water heater can lead to poor performance, especially if your household has a high demand for hot water during peak hours.

You’ll also want to be mindful of water quality. If you have hard water, you’ll need to flush the unit regularly to avoid buildup in the heat exchanger. Neglecting this could reduce efficiency or even shorten the life of your tankless heater. Regular descaling is a key part of water heater maintenance, especially in areas with mineral-rich water.

Which Type is Best For You

Choosing the right model comes down to your home’s unique needs. A gas tankless water heater is a powerful choice for larger homes or those already using natural gas, while an electric tankless water heater is simpler to install and more suitable for smaller residences. You’ll also want to consider the types of tankless models, condensing units are more efficient, while non-condensing models are less expensive but may release more heat waste.

What many homeowners appreciate most is the overall efficiency of tankless water heaters. Since these units only operate when there’s a flow of water, they avoid the standby energy loss that plagues traditional tank water heaters. Over time, that adds up to real savings. And because you will know which is better, a tankless water heater or a tank. The tankless types deliver hot water instantly and consistently, they make daily routines more comfortable and stress-free.

Always Consult with a Professional Plumber

If your current hot water heater is nearing the end of its life or simply isn’t keeping up with your hot water needs, now could be the perfect time to explore a new tankless water heater. With proper planning and professional installation, you’ll enjoy all the benefits of hot water on demand while lowering your home’s energy footprint. Whether you're upgrading your entire water heating system or just replacing an aging unit, switching to a tankless could be the long-term comfort upgrade your home deserves.
