Is a Tankless Water Heater Right for You?
Why homeowners choose tankless
- Hot water on demand instead of a limited tank
- Compact, wall-mounted unit that frees floor space
- Often a longer lifespan than a tank heater
- No standby heat loss from a stored tank of water
What to consider first
- Higher upfront cost than a tank heater
- Gas line, venting or electrical upgrades may be needed
- Each unit has a limit on how many fixtures it can run at once
- Hard water means regular descaling

Gas Line & Venting: Why It Matters
Tankless heaters burn more gas at once than a tank unit, so switching often means more than a like-for-like swap. Before we quote a job, we check:
- Whether your existing gas line is large enough for the unit
- Venting route, material and clearances required by the manufacturer
- Combustion air, condensate drainage and power supply for the unit
- Water supply, shutoff valves and service valves for future flushing
- Permit and code requirements for the work
Hard Water & Descaling
Where water is hard, minerals build up as scale inside the heat exchanger of a tankless heater. Scale makes the unit work harder, can cause error codes and cold water bursts, and shortens its life. A regular flush and descale, usually once a year or as your manufacturer recommends, is the simplest way to protect your investment.
If hard water is a problem in your home, we can also talk to you about a water softener or treatment system. See our water softener installation page.

Tankless Water Heater FAQs
Is a tankless water heater worth it for my home?
It depends on how much hot water you use and what your home needs for gas and venting. Tankless units give hot water on demand, save space and can last longer than tank units, but they usually cost more to install. Our guide on tankless vs traditional water heaters compares both.
Do tankless water heaters really give endless hot water?
They heat water as it flows, so they do not run out the way a tank can. Each unit still has a limit on how much water it can heat at once, so it has to be sized for how many fixtures you run at the same time.
Why does my tankless water heater need descaling?
Minerals in hard water form scale inside the heat exchanger. Scale reduces efficiency, can trigger error codes and shortens the life of the unit. Regular descaling, often once a year or as the manufacturer recommends, helps prevent this.
Can you install a tankless water heater in place of my tank?
Usually yes, but the job often includes more than swapping the unit. A tankless heater may need a larger gas line, new venting or an upgraded electrical circuit. We check all of this before we quote.
My tankless water heater shows an error code or gives cold bursts. What should I do?
Error codes and cold water bursts can come from scale buildup, a blocked vent or air intake, low gas supply or flow problems. Check your manual for the code, then call us for a proper diagnosis. If you smell gas, leave the house and call 911 or your gas utility.
Do you repair and service all tankless brands?
We work on most common tankless water heaters. Tell us the brand and model when you call, and we will confirm before we come out.
