Boiler installation & replacement
Boiler replacement in Morristown and the surrounding towns
Replacing a boiler is a bigger decision than fixing one. Here is what the job involves, what changes the price, and how to tell whether your current boiler is worth another repair.

What a boiler replacement actually involves
A replacement is a day or more of work, not a call-out. We look at the whole heating system, not just the appliance, because the boiler you install has to suit the piping, the venting and the way your house is zoned.
We start by sizing the boiler to the house. An oversized boiler short-cycles and wears itself out; an undersized one never keeps up on the coldest nights. Sizing depends on the heat loss of the building, not on the output printed on the unit you already own — houses that have had insulation, windows or an addition done since the last boiler often need a different size than the one being removed.
From there we work out what else has to change. Some replacements are close to like-for-like: the new boiler sits where the old one sat, ties into the existing supply and return, and reuses the venting. Others involve moving to a different venting arrangement, replacing near-boiler piping, adding or repairing circulators and zone valves, fitting a new expansion tank, or tying in an indirect water heater. Old cast-iron systems in the older parts of Morristown, Mendham and Bernardsville frequently need some of the surrounding pipework brought up to date at the same time — that is usually where the difference between two quotes comes from.
On installation day we drain and remove the old boiler, set and pipe the new one, handle the gas or oil connection, vent it correctly, refill and purge the system, set the controls, and fire it up while we are still there to confirm every zone is heating. Permit and inspection requirements vary by town, so ask us what applies at your address before you schedule.
All of this is carried out under NJ Master Plumber LIC# 7857/220. We have been doing this work in Morris and Somerset County for 38 years.

Repair or replace
When replacing is the better spend
Most boilers get repaired several times before they get replaced, and that is usually the right order. These are the situations where another repair stops making sense.
The boiler is old and the repairs are stacking up
One repair on an ageing boiler is normal. A third repair in two winters, on a unit that is near the end of its service life, is money spent on a system you are going to replace anyway.
The failed part is a major one
A cracked heat exchanger or section, or a failure that costs a meaningful share of a new installation, tips the decision. Small controls and pump failures usually do not.
Parts are hard to get
Once a model is out of production, a repair can mean waiting for a part in the middle of a cold week. That is worth weighing if the boiler is already marginal.
The house has changed
Additions, new windows or new insulation change what the house needs. A boiler that was right twenty years ago may be badly matched now.
It cannot keep up or heats unevenly
If some zones never come up to temperature and the system has already been balanced and purged, the problem may be the boiler or the way it is piped rather than a single faulty part.
If you are not sure which side of the line you are on, have it looked at first. We would rather repair a boiler that has good years left in it than sell you a replacement you do not need yet.
Cost
What drives the price of a boiler replacement
We price each installation after seeing the system, because the boiler itself is only part of the cost. These are the factors that move the number most.
Size and type of boiler
Output, fuel type and the class of unit you choose. Higher-efficiency units cost more up front and change the venting requirements.
Condition of the existing piping
A clean like-for-like swap costs less than one where the near-boiler piping, circulators, zone valves or expansion tank need replacing too.
Venting and the chimney
Reusing an existing flue is one job. Changing to direct venting through a wall, or working around a chimney that is no longer suitable, is another.
Domestic hot water
Whether the new boiler needs to feed an indirect tank, and whether that tank is being replaced at the same time.
Zoning and controls
The number of heating zones, and whether thermostats and controls are being carried over or replaced.
Access, removal and permits
How difficult the old unit is to get out of the basement, disposal, and whatever permit and inspection your town requires.
Ask for an estimate and we will look at the system, tell you what your installation needs and what it does not, and price it before any work starts.
Questions we get about boiler replacement
How long does a boiler replacement take?
A straightforward replacement is usually completed in a day. Jobs that involve repiping, changing the venting arrangement or adding an indirect water heater can run longer. We will tell you which one yours looks like when we quote it.
Will I be without heat?
You are without heat while the old boiler is out and the new one is being piped in — that is normally within a single working day for a like-for-like swap. If your boiler has already failed and you have no heat now, call us; emergency service is available.
Do I need a permit?
Permit and inspection requirements are set by your municipality and vary between the towns we cover. Ask us and we will tell you what applies at your address.
Can I put the same size boiler back in?
Not always. If the house has had insulation, windows or an addition done since the last boiler went in, the right size may have changed. We size to the house rather than copying the label on the old unit.
Who does the work?
The installation is carried out under NJ Master Plumber LIC# 7857/220. We have been working in Morris and Somerset County for 38 years.
Should I repair instead?
Often, yes — especially if the boiler is not near the end of its life and the failed part is a minor one. See our boiler repair page, or call and we will look at it before recommending a replacement.
