Tankless Water Heaters

Endless hot water. Less space. Longer life.

Call (203) 823-8992Request Service

Tankless water heaters deliver hot water on demand — no standby loss, no tank to fail, and often a 20+ year lifespan. We install and service Rinnai, Navien, and other leading brands, sized correctly for your home's flow rate and Connecticut's cold winter groundwater. A tankless retrofit is a different job than a tank swap: it usually needs a larger gas line, dedicated stainless or PVC venting, and a condensate drain, and getting those three details right is the difference between endless hot water and a unit that runs cold every February.

What's included

  • Rinnai, Navien, Rheem, Noritz
  • Correct sizing for CT winter groundwater temps
  • Gas line and venting upgrades handled in-house
  • Condensate drainage and neutralizer where required
  • Annual descaling service to protect your warranty
  • Recirculation options for instant hot water
  • Permits pulled and inspections coordinated

Our process

1

Size the load

We calculate your peak simultaneous demand against winter inlet temperature so the unit never runs cold mid-shower.

2

Upgrade what's needed

Most tankless installs require a larger gas line, dedicated venting and a condensate path — we handle all three.

3

Register & maintain

We register your warranty and set you up on an annual descaling schedule.

Why Connecticut homeowners choose Drain Wizard for tankless water heaters

Tankless Water Heaters in an older Connecticut home rarely fits a one-size-fits-all repair. Greater New Haven's housing stock spans century-old cast iron and galvanized systems, mid-century copper and clay laterals, 1970s Orangeburg, and modern PEX & PVC — each behaves differently and each has a right way to service it. Drain Wizard is a family-owned, Connecticut P1-licensed plumbing contractor based in Hamden, and tankless water heaters is core to what our experienced plumbing professionals do every week across Hamden, North Haven, Wallingford, Cheshire, Branford, Guilford, Madison, Milford, Meriden, New Haven and the rest of the region.

Every tankless water heaters call starts with a real diagnosis — not a guess — and a detailed written estimate you approve before any work begins. We show up when we say we will, protect your home with drop cloths and shoe covers, and stand behind the workmanship with the Drain Wizard Guarantee. If a permit or inspection is required, we pull it and see it through.

Frequently Asked Questions

Will a tankless keep up in Connecticut winters?+
Yes — when it's sized for our cold groundwater. Inlet water here can drop near 40°F in February, which cuts a unit's usable flow rate roughly in half compared to its summer rating. Undersized units are why some homeowners have had bad experiences.
Tankless or a standard tank — which should I choose?+
A tank costs less up front and installs in a day. Tankless costs more up front, frees up floor space, and typically lasts twice as long with lower monthly energy use. If your current tank is in a tight utility closet or you routinely run out of hot water, tankless is usually worth the conversion.
How much more does a tankless conversion cost than a tank?+
A tankless retrofit runs meaningfully higher than a like-for-like tank replacement because of the gas line, venting and condensate work involved. We give you a written flat-rate price for both options so you can compare them side by side before deciding.
Does a tankless need a bigger gas line?+
Almost always. A tankless burns far more gas while it's running than a tank does, so the existing branch line is frequently undersized. We size and run the correct line as part of the install rather than leaving you with a unit that can't reach full output.
How often does a tankless need service?+
Annual descaling is required to maintain most manufacturer warranties, especially in areas with hard water. Skipping it is the most common reason a tankless underperforms after a few years.
How long does a tankless water heater last?+
20+ years is realistic with annual descaling, roughly double a standard tank. Most units also have field-replaceable parts, so a single failed component doesn't mean a whole new heater.
Can I get instant hot water at a far bathroom?+
Yes, with a recirculation loop or a dedicated recirculation-capable unit. We'll tell you whether your layout supports it before you pay for it.
Is tankless worth it?+
For most families, yes — 20+ year lifespan, lower energy bills, reclaimed floor space, and no cold showers on holidays.
