How to Install a New Boiler

How to install a new boiler are one of the most expensive appliances in a home but they can also save energy costs and reduce environmental emissions by running more efficiently.

When you’re ready to install a new boiler, consider having it done in the summer as this is a less busy season for HVAC professionals and can be more affordable. You’ll want to talk to a few different contractors to get cost estimates so you can compare options. Be sure to ask about any rebates and incentives your home may be eligible for and what tax credits you can take advantage of.

How to Install a New Boiler: A Step-by-Step Guide

Once you’ve hired your contractor, they’ll start by shutting off gas at the meter and possibly disconnecting water valves (depending on the type of system being replaced). Then, they’ll remove the old boiler and drain down the existing systems. Once the pipework is prepped, your new boiler will be delivered and installed. They’ll re-connect the gas and water pipes, as well as connect the thermostat and electric power cables.

Your contractor will test the water pressure and the boiler to make sure everything is working as it should. They’ll also walk you through how the new system works and demonstrate some basic maintenance like topping up the pressure, bleeding a radiator and general safety. You’ll also need to register your new boiler with the manufacturer so you can receive any applicable warranties and support.
