Tankless systems provide hot water on demand without the need for a storage tank.
For the right home, they deliver consistent hot water, improved efficiency, and a compact footprint. The key is making sure your home is properly suited for one.
Straight Up Mechanical helps homeowners determine whether this type of system is the right fit for their household, installs it correctly when it makes sense, and services it properly over the long term. Every recommendation is based on assessment first, not upselling.
Replacing a traditional tanked unit with an on-demand system is a smart upgrade for many homes. When installed correctly, it delivers consistent hot water, improved efficiency, and long-term reliability.
Straight Up Mechanical approaches installation with a clear focus on proper system matching and performance. Each project begins with an evaluation of household hot water demand, including bathrooms, fixtures, and peak usage, to ensure the system is correctly sized.
During installation, Straight Up Mechanical addresses the details that make these systems perform as intended:
By treating the replacement as a full system upgrade rather than a simple swap, Straight Up Mechanical ensures the new setup integrates seamlessly with the home and performs reliably from day one.
When an on-demand system is not working properly, accurate diagnosis is essential. Straight Up Mechanical provides professional repair and service focused on identifying the cause of the issue and restoring reliable hot water.
These systems include built-in diagnostics, and many problems can be resolved through proper servicing rather than replacement. Common issues include no hot water, inconsistent temperatures, error codes, or shutdowns during peak use.
Service typically includes:
In many cases, performance problems are caused by maintenance or configuration issues rather than system failure. Professional service helps extend system life and ensures safe, efficient operation in the home.
Regular maintenance is essential to keep on-demand systems operating efficiently and reliably. Skipping service can reduce performance and shorten system lifespan.
In Metro Vancouver, mineral content in the water can lead to scale buildup inside the heat exchanger. Annual flushing and inspection help prevent:
Ongoing maintenance helps ensure consistent hot water, protects internal components, and safeguards the homeowner’s investment.
The cost of installing an on-demand hot water system reflects how well it is matched to the home. Each installation is tailored to household demand, ensuring consistent performance and long-term reliability. At Straight Up Mechanical, pricing is clearly explained in advance, with no surprises during installation.
Pricing is influenced by factors such as:
While these systems often have a higher upfront cost than traditional tanks, many homeowners choose them for the long-term benefits of efficiency, performance, and extended lifespan when professionally installed.
Homeowners often choose on-demand hot water systems for the consistent performance and efficiency they provide. When properly installed, they deliver hot water without the limitations of a traditional storage tank.
These systems are a good fit for homes that value:
For households with higher demand or overlapping hot water use, this type of system offers a practical and long-term solution when matched correctly to the home.
We recommend Navien and Rinnai tankless water heaters.
We chose these brands primarily because of their exceptional customer support. When customers need hot water restored quickly, having reliable manufacturer support is critical. Both brands provide:
With Navien and Rinnai, you can count on us to quickly resolve any issues, and we have established relationships with local reps who can help locate parts or provide solutions even when standard suppliers might have delays. This level of support ensures your tankless system gets back up and running as quickly as possible.
A tankless system heats water only when it is needed rather than storing hot water in a tank. When a fixture is turned on, water is heated on demand and delivered directly.
With proper installation and regular maintenance, these systems typically last longer than traditional tank units. Lifespan depends on water quality, usage, and ongoing service.
They can be a good investment for homes with higher hot water demand or where efficiency and space savings are priorities. They are not the best option for every household.
A properly sized system can support multiple fixtures at the same time. Undersized systems may struggle during peak demand, which is why correct sizing is critical.
They can work well in condos, but electrical capacity, venting options, and strata requirements must be reviewed before installation.
Most residential systems should be serviced and flushed once per year, especially in areas with mineral-heavy water.
Most systems require electricity to operate, including gas models. During a power outage, hot water is typically unavailable unless backup power is provided.
We provide tankless water heater services in Vancouver and across the Lower Mainland / Greater Vancouver area, including:

Straight Up Mechanical came exactly as booked, did not make a mess, the price was reasonable and the technician was concerned that the job was done right. I would definitely call them for future jobs and not even think twice. Roy SargleppTrustindex verifies that the original source of the review is Google. I had a leak in my washroom. I talked with Willem, and he booked an appointment with his business partner for the same day. I don't remember his name, but he was very polite and professional and did a great and fast job. Not only did he fix the leaking, but he also had time to install a faucet. Excellent service and a great price, and I highly recommend it.
