Boiler Installation in Novato

Signs It’s Time to Replace Your Boiler

Not every boiler problem calls for replacement, but some signs point clearly in that direction. Knowing what to look for helps you make an informed decision before small issues become expensive ones.

• Age over 15 to 20 years: Older units lose efficiency over time, and parts become harder to source
• Rising heating bills: A steady climb in energy costs without a change in usage often means declining efficiency
• Frequent repairs: When repair calls become routine, investing in a replacement backed by a fresh labor warranty is usually the wiser call
• Leaks or corrosion: Visible rust or water around the unit signals compromised structural integrity
• Yellow burner flame: A gas boiler should burn blue. A yellow flame can indicate incomplete combustion and a potential carbon monoxide risk
• Uneven heat: Radiators or zones that never fully warm may point to a system losing capacity
• Short cycling: A boiler that kicks on and off frequently without reaching set temperature is working harder than it should

Boiler Types We Install

The right boiler depends on your home’s size, existing distribution system, number of heating zones, and hot water demand. Here’s a brief look at the main options:

High-Efficiency Condensing Boilers

These units reach AFUE ratings of 90 percent and above, making them a strong fit for radiant floor systems and hydronic baseboard setups common in Marin County homes. Many older homes with cast-iron radiators or existing baseboards can be upgraded to a condensing unit with the right venting and piping adjustments.

Combi Boilers

A combi boiler handles both space heating and domestic hot water from a single compact unit, making them practical for smaller homes, ADUs, or remodel projects where space is limited and simplicity matters.

Boiler with Indirect Water Heater

Pairing a boiler with a dedicated indirect water heater suits larger homes or properties with high hot water demand. The boiler heats the water heater through a heat exchanger, providing reliable capacity without a separate fuel source.

What to Expect During Installation

We start with a site assessment to evaluate your existing distribution system, available space, venting requirements, and fuel access. From there, we perform a heat load calculation to size the new unit correctly. Oversizing and undersizing both create efficiency and comfort problems, and proper sizing helps avoid them.

Boiler installations in Novato require building and mechanical permits. Our licensed team handles permit procurement and coordinates final inspection so you don’t have to manage that process yourself. Installation day covers removing the old unit, setting the new boiler, connecting to gas and electrical feeds, integrating with the existing hydronic distribution, and commissioning the system.

When the work is complete, we can walk you through system operation, thermostat and zone controls, and basic maintenance so you know exactly how your new system works.
