Signs You Need a New Boiler

Not sure if your boiler needs repair or full replacement? Here are some common signs that it might be time for a new unit:

  • Rising Energy Bills: Older boilers lose efficiency over time, causing your energy costs to spike.
  • Uneven Heating: Cold spots or inconsistent warmth may mean your boiler can no longer circulate heat properly.
  • Frequent Repairs: If you’re calling for boiler service more than once a season, replacement may be more cost-effective.
  • Visible Leaks or Corrosion: Leaking valves or rust on your boiler body or piping is a clear warning sign.
  • Strange Noises: Banging, whistling, or gurgling sounds often indicate major internal wear or circulation problems.
  • Inadequate Hot Water: Boilers that double as water heaters can lose hot water capacity as they fail.
  • Age Over 15–20 Years: Even a well-maintained boiler can decline in performance after 15–20 years of use.
  • Pilot Light Issues: Constantly going out or yellow/orange flames may point to combustion problems.

A One Stop Shop for Boiler Installation & Replacement

Replacing your boiler is a major investment—but one that pays off with lower energy bills, better comfort, and peace of mind. We walk you through every step, from choosing the right unit to making sure it’s installed cleanly and safely
  • Professional System Sizing

    When it comes to boiler performance, size matters. A system that’s too small won’t keep you warm. Too large, and you’ll waste energy and money.

    We perform a full heat load calculation to determine exactly what your home needs. That includes square footage, number of zones, insulation quality, and your domestic hot water use, if applicable.

    No guesswork. No upselling. Just the right fit for lasting comfort.

  • High-Efficiency Boiler Options

    Modern boilers offer more than just heat—they offer smarter energy use and better long-term value.

    Available options include:
    • Gas condensing boilers
    • Combination units for heating and hot water
    • Compact wall-mounted systems
    • Multi-zone compatible models
    • Upgrades from oil to gas

    We’ll help you compare features and qualify for any local or utility rebates available.

  • Removal of Old Boiler

    Before a new system goes in, the old one has to come out safely. We disconnect the boiler, cap utility lines, and dispose of the unit in accordance with local regulations.

    We’ll prep the area for the new install and make sure the transition is smooth, minimizing downtime for your household.

  • Complete Boiler Installation

    Installing a boiler is a precise job, and we take care of every connection—water, gas, venting, and electrical—to meet both code and manufacturer requirements.

    Our process includes:
    • Installing expansion tanks and valves
    • Connecting baseboards or radiators
    • Programming thermostats and zones
    • Testing for safe combustion and system pressure

    Before we finish, we’ll explain how to use your new system and answer any questions.

  • Permits, Rebates, and Final Inspection

    We manage the entire backend of your install. From pulling permits to submitting rebate paperwork, you don’t have to lift a finger.

    We’ll handle:
    • Local permit filings and inspection scheduling
    • Final pressure and combustion testing
    • Warranty registration and rebate documentation

    We ensure your new boiler is not only efficient, but also fully code-compliant and ready for years of dependable use.

Karen Helsel

We found Crystal Water Plumbing when our well pump stopped working. They came out, diagnosed and gave us an estimate, and then repaired the two-fold problem (both the pressure switch and the pump itself had failed) within the day. They also noticed other items, and quickly addressed all of the issues, and now we have a well that should give us decades of worry-free service.
