What Sets DiBacco Plumbing, Heating and Cooling Apart for Tankless Installation
Choosing an installer is as important as choosing the unit itself. Forty-one years of plumbing and heating field experience shapes how we approach every tankless installation, from sizing the unit to match your household’s simultaneous hot water demand to confirming the gas line has the capacity the new unit requires. Our team operates with Master Plumber precision, and all work meets or exceeds current New Hampshire building codes.
Gas line hookups for tankless units get the same rigorous treatment as any gas piping project we take on. We perform pressure testing on all gas work and follow strict local utility regulations, so the installation is safe and code-compliant from day one. Southern NH water can carry enough mineral content to accelerate scale buildup inside tankless heat exchangers, and we can walk you through water quality considerations during the assessment.
Every installation with us includes:
- A pre-installation evaluation of your home’s hot water demand, plumbing layout, and gas or electric supply
- Arrival in a clearly marked vehicle with the tools and parts needed to complete most jobs in one visit
- A clean, protected workspace throughout the job
- A final walkthrough so you understand how to operate and maintain your new system
- Honest estimates with no jargon and no pressure
- Senior citizen and military veteran discounts on all service calls
NHSaves Rebates & Financing for Nashua Homeowners
Nashua homeowners who are customers of Liberty or Unitil may qualify for the NHSaves rebate program, which currently offers up to $500 on qualifying high-efficiency tankless water heater models. Rebate amounts and funding availability are subject to change, and installation by a licensed contractor is required to qualify. We’ll review your eligibility as part of the free estimate so you know what savings may apply before any work begins.
If you’d rather spread the cost over time, we offer financing and flexible payment plans to fit a range of budgets. Current program details are available on our rebates page at dibaccoplumbing.com/hvac-plumbing-rebates/. Between potential rebates and financing options, a tankless upgrade is more accessible than many homeowners expect.
