Ever turned on the shower and waited for hot water that never came? It happens often in homes with old water heaters. That is why many people now ask about switching to tankless water heaters. The big question is this: are tankless water heaters worth it?
It has been observed that homes with tankless heaters use up to 34 percent less energy than homes with old-style tank heaters. That can save money every year.
In this blog, Dript Plumbing & Heating is here to help you make the right choice. Let’s take a closer look.
Key Takeaways
What Is a Tankless Water Heater?
It does not store hot water like a regular tank heater. It passes cold water through a heat exchanger to warm it as it flows. These units are also called on-demand water heaters because they only provide hot water when needed.
At Dript, we install and service electric and gas models. We offer our plumbing and heating services in Kitsilano at any time.
How Does a Tankless Water Heater Work?
Here is how the system works.
- Open a hot water fixture like a faucet or shower valve.
- Cold water flows into the unit through the supply line.
- A flow sensor detects water movement and signals the control board.
- The control board activates the gas burner or electric heating element.
- Water passes over the heat exchanger and absorbs the heat.
- Heated water exits through the outlet pipe and reaches your fixture.
There is no standby heat loss because there is no storage tank, making the system more energy-efficient. To plan your full setup, check your guide to the best heating system in Canada.
Types of Tankless Water Heaters
There are different types based on how they heat water and where you install them. Each type has its use and setup.
Electric Tankless Water Heaters
These models use rods to warm the water flowing through the system. These are compact and easy to install in homes with basic electrical service. They work well in small homes or point-of-use setups like a single sink.
Electric units need less maintenance than gas models but require flushing to prevent mineral buildup.
Gas Tankless Water Heaters
These heaters use a gas burner to heat the water. They heat water faster than electric models and work well for large homes with high demand. Proper venting and a gas line with enough capacity are required.
Gas models may need more frequent maintenance. That includes burner checks and descaling if your home has hard water. Regular tankless water heater maintenance can help the system run longer and safer.
Condensing vs Non-Condensing Gas Units
Condensing units reuse heat from exhaust gases. This makes them more efficient. They also use PVC venting which lowers installation costs.
Non-condensing units vent hot gases right away. These need metal venting and may lose more heat. They cost less up front but use more energy over time.
Point-of-Use Tankless Water Heaters
These small units are placed near a single fixture, like a bathroom sink. They supply hot water quickly in areas far from the main system. They are often electric and need low maintenance.
Point-of-use models are a smart pick for upgrades or add-ons. They also help reduce water waste in large homes.
Every system needs care to stay efficient. Contact Dript Plumbing & Heating for maintenance or heating system installations.
Benefits of Tankless Water Heater
Tankless water heaters offer clear benefits for small and large homes. They use less energy and provide steady hot water without delay.
Endless Hot Water on Demand
Tankless units heat water only when you open a tap. This gives you hot water anytime without waiting. It works well for homes with back-to-back showers or large families.
There is no risk of running out since there is no storage tank. At Dript Plumbing & Heating, we set flow rates to match your home’s needs.
Energy Savings Over Time
Tankless models do not store hot water, so there is no standby heat loss. They turn on only when water flows, so you use less gas or power.
This lowers your utility bills month after month. With regular tankless water heater maintenance, the system works efficiently for years.
Longer Lifespan
A well-maintained tankless heater can last over 20 years. This is more than a tank-style system which may fail after 10 to 15 years. Flushing the system and cleaning the inlet screen help prevent scale buildup.
Space-Saving Design
Tankless units mount to the wall. Unlike tank heaters, they do not need a large floor area, which frees up space in basements or utility closets. Electric units are smaller and fit well in tight places.
Cleaner Water and Less Rust
Since there is no tank, there is less risk of rust and sediment mixing with your water. This keeps your fixtures and pipes cleaner. Tankless systems also work better with filtration. That reduces the chance of scale buildup and lowers the need for extra repairs.

Disadvantages of Tankless Water Heaters
Tankless water heaters offer many benefits but a few downsides. It is essential to know these before installing one at home.
Higher Upfront Cost
Tankless units cost more than standard tank heaters. The parts and setup require extra work, such as gas line upgrades or electrical changes. In most cases, you also need venting or wall brackets.
Even though the long-term savings are real, the first price can be hard for some homeowners.
Limited Flow Rate
Tankless heaters supply water as it flows. The unit may not keep up if two showers and a washing machine run simultaneously. You may need more than one unit or a higher flow rate model. A licensed plumber at Dript can help size the unit for your home.
Need for Regular Maintenance
Tankless systems need care to work well. Scale buildup can block the heat exchanger, which lowers efficiency and possibly damages the unit over time.
Slow Hot Water Delivery to Distant Fixtures
Hot water may take time if a faucet is far from the unit. The heater must detect flow, heat the water, and send it through long pipes. To fix this, you can add a recirculation pump, which adds more cost. It is good to plan the location of the heater before the installation.
Is a Tankless Water Heater Right for You?
A tankless water heater is a wise choice for many homes but not for all. It depends on
- How much hot water do you use
- How your home is built
- What type of plumbing system do you have
A single unit may work well if your home has low water demand or uses water at one fixture at a time. If your family uses two or more showers at the same time then you may need a unit with a high flow rate.
You should also check if your gas line or electric panel can handle the load. Older homes may need upgrades before installation.
Conclusion
For on-demand hot water requirements, a tankless water heater can be a great fit. It lasts longer than a tank system when you take care of it and helps save money over time. But it may not work well for every home. You must first check your water needs, plumbing setup, and power supply.
