What to Know Before Making the Switch

Before investing in a tankless hot water heater, it’s important to understand how these systems work and what to expect once installed. From installation requirements and ongoing maintenance to performance differences and local factors in Vernon, knowing the basics upfront will help you choose the right system and avoid unexpected costs or limitations.

Pros & Cons: What You Should Consider

Advantages

  • Energy efficiency & savings
    Because they only heat water when needed, tankless heaters can reduce energy use. For many homes, that means 8–14% less energy usage versus a tank heater.

  • Endless hot water
    As long as demand doesn’t exceed its capacity, a tankless unit can provide continuous hot water.

  • Compact size & space-saving
    Tankless units mount on walls and take far less space than bulky tanks.

  • Longer lifespan
    A well-maintained tankless system may last 15–20 years or more, outlasting many storage tanks.

Disadvantages / What to Watch Out For

  • Higher upfront cost & installation complexity
    Buying and installing a tankless unit often costs more initially. You may need upgrades to gas lines, venting, or electrical capacity.

  • Flow / simultaneous use limitations
    If multiple fixtures (e.g. shower + washing machine) run hot water at once, a single tankless unit might struggle to keep up.

  • Maintenance requirement
    Mineral buildup and scale can reduce performance over time. Regular descaling and upkeep are essential.

  • Delay in getting hot water & cold-water sandwich effect
    Because the system must activate before heating, you may notice a brief delay or a “cold shot” during transitions.

  • Dependence on utilities Electric models require sufficient power lines; gas models need proper venting and gas supply. In power outages, you won’t get hot water.

Is a Tankless Hot Water Heater Right for Vernon Homes?

Here are several local considerations that influence whether a tankless system makes sense in Vernon:

  1. Cold Incoming Water
    Colder supply water means the heater needs more energy to raise temperature, which may demand a stronger unit.

  2. Water quality & mineral content
    Hard water leads to buildup. If Vernon’s water has minerals, you’ll want a model and maintenance plan that handle scale.

  3. Household hot water usage patterns
    If your home frequently uses several hot water appliances simultaneously, you’ll want a system sized accordingly, or possibly multiple units.

  4. Ventilation & installation spaces
    Wall mounting and proper venting must be planned, especially in existing homes.

  5. Utility rates & energy savings
    Check your local gas and electric rates. The energy savings must justify the higher upfront cost over time.

Brown Mechanical Services in Vernon offers consultations to evaluate your home’s specific needs, plumbing layout, and usage patterns to see if tankless is the right fit.

Addressing Common Concerns & Objections

“Will I run out of hot water?”
No, as long as your usage doesn’t exceed the heater’s capacity. But if many fixtures use hot water simultaneously, plan for that demand or consider multiple units.

“What about the higher cost?”
Yes, upfront costs tend to be higher. But many users recoup that through lower energy bills and longer lifespan if the unit is well matched and maintained.

“Is maintenance difficult?”
With regular descaling and filter checks, it’s manageable. Many units offer service valves that make maintenance simpler.

“Will the water ever turn rusty or discolored?”
Occasionally, sediment in pipes or oxidation of iron salts can cause discoloration. Flushing, filtration, and proper installation help avoid this.

“What happens during power outages?”
Electric tankless units won’t function in outages. Gas units may still work if gas and venting remain intact, though they might require electricity for control systems.

Installation & Maintenance Tips

  • Work with licensed professionals (like Brown Mechanical) to size & install correctly.

  • Descale regularly (once or twice a year depending on water quality).

  • Use a filter or water softener if local water is hard.

  • Flush piping occasionally to clear sediment.

  • Check venting, gas, or electrical connections annually.

  • Monitor performance (flow, temperature) so issues are caught early.
