How much for instant hot water at the NB kitchen sink?

Adding instant hot water at your kitchen sink in New Brunswick typically runs $500–$1,500 installed, depending on the system you choose and the electrical work required.

There are two main ways to get near-instant hot water at the kitchen sink: a point-of-use (POU) electric water heater mounted under the sink, or a hot water recirculation system that keeps your existing hot water line primed and ready. Each has different costs, installation requirements, and trade-offs worth understanding.

Point-of-Use Electric Water Heater

A small tank-style or tankless electric unit installed directly under the sink delivers hot water in seconds without waiting for your main water heater to push hot water through the pipes. Tank units (2–7 gallon) run $150–$400 for the unit and are straightforward to install — they connect to your existing cold supply line and drain. The catch in NB is electrical: these units require a dedicated 120V or 240V circuit, and if you don't already have one at the sink location, you're looking at an electrician running a new circuit. That adds $300–$700 depending on panel distance and whether your panel has capacity. In older NB homes with 60-amp panels — very common in homes built before 1980 — a panel upgrade may be needed before adding any new circuits.

Hot Water Recirculation System

A recirculation pump installs at your water heater and keeps hot water continuously (or on a timer/sensor) moving through your supply lines so it's always ready at the tap. Units like the Watts or Grundfos systems run $200–$500 for the pump, plus $300–$600 for a plumber to install it properly. This is the better choice if you're frustrated with waiting 30–60 seconds for hot water throughout the whole house, not just the kitchen. The downside is slightly higher energy use year-round, though timer-controlled models minimize that.

NB-specific consideration: In many New Brunswick homes — especially those built in the 1960s through 1990s — the water heater is in the basement and the kitchen is on the main floor with long pipe runs. This is exactly the situation where recirculation systems shine. If your home has galvanized supply pipes (common pre-1980), a plumber should assess their condition before adding a recirculation system, since corroded pipes reduce flow and can cause pressure issues.

Practical tips before you start: Check your electrical panel capacity first — this is the most common surprise cost. If you're already planning a broader kitchen renovation, this is the ideal time to add a dedicated circuit since the walls may already be open. For recirculation systems, a timer set to your morning and evening routines keeps energy costs minimal.

Both options require a licensed plumber for the water connections and a licensed electrician for any new circuit work — both of which require permits in NB if new circuits are being added. Don't skip the permit; electrical inspections protect you and your home insurance coverage.
