Choose the type before the brand
Most installs begin with three questions: what fuel do you have, how much hot water do you use at peak, and where will the unit sit. The answers narrow the field faster than a brand comparison does.
Storage tank (gas or electric)
- Lowest purchase price of the common options
- Simplest swap into an existing setup
- Keeps 40 to 50 gallons hot at all times
- Runs short if several fixtures run at once
Tankless or heat pump
- Tankless heats on demand and frees floor space
- Tankless needs higher gas or electric capacity and special venting
- Heat pump uses air heat and needs clearance and a condensate drain
- Higher upfront cost for both types
Our tankless water heater page covers on-demand units in more detail, including descaling and error codes after the install.
Venting and combustion air for gas units
Gas water heaters have to send exhaust outside, and how they do it depends on the model. A natural draft tank rises through a metal flue into a chimney or vent pipe. A power vent uses a fan and plastic pipe through a wall. A direct vent pulls combustion air from outside and exhausts through a paired pipe.
In a tight basement, combustion air matters. A closed closet with no air supply can starve the burner and push exhaust back into the room. We check the space, the vent slope and the clearance to nearby materials before the unit is set.
Gas piping and appliance venting are covered by the National Fuel Gas Code, NFPA 54, and the Township permit page lists water heaters as permit work, along with heating and AC replacement. Call Code Enforcement at (215) 643-3131 to ask who files it for a gas job. If the gas line is undersized or the flue is deteriorated, we flag it in the quote instead of after the old tank is gone.
Gas line caveats we raise before the job
Pipe size
Moving from a tank to a tankless unit often needs a larger gas line because the burner draws far more at once.
Shutoff and sediment trap
A shutoff valve and a drip leg at the appliance should be in place and reachable.
Flex connector condition
An old connector that is kinked, corroded or past its rating gets replaced with the new unit.
Gas odor
If you smell gas at any point, leave the building, then call 911 or your gas utility (for PECO customers, 1-800-841-4141) before you call anyone else.
Electric and heat pump installs: circuits, breakers and clearance
An electric tank pulls substantial power, so the circuit has to match the nameplate. Wire size and breaker rating come from the unit's label and local code, and an older panel with little spare capacity can change the job. We read the label and the panel before quoting.
A heat pump water heater adds a few extra needs. It wants open air around it, headroom for the top-mounted unit and a place for condensate to drain. A basement with an existing floor drain is a good fit, and a tight utility closet usually is not.

What the installer brings and what to have ready
Before install day
- Photograph the old heater's data plate and the area around it
- Clear 3 feet or more around the heater and the path from the door
- Know where the main water shutoff is and that it works
- Note your fuel type and any plan to change it
- Plan for a few hours without hot water on install day
- Call Code Enforcement at (215) 643-3131 (Monday to Friday, 8:30 to 4:30) and ask who files the water heater permit
How the installation goes
- 1
Site visit and sizing
We measure the space, check the fuel supply and vent route, and recommend a capacity that suits your household.
- 2
Remove the old unit
Water and fuel are shut off, the tank is drained and disconnected, and the old unit is hauled away.
- 3
Set and connect
The new unit is leveled, piped with new connectors and valves, vented and fitted with a relief valve and discharge pipe, plus an expansion tank where needed.
- 4
Start-up and walkthrough
We fire or power it, check for leaks and combustion, set the temperature and show you the shutoffs.
What affects the price of a water heater installation
Installation pricing varies for reasons you can see on the job site.
Unit type and capacity
Tank, tankless and heat pump models sit at very different price points, and capacity changes the cost within each type.
Venting changes
Switching vent type, running new pipe through a wall or lining a chimney adds material and labor.
Gas or electrical upgrades
A larger gas line or a new circuit and breaker is separate work from setting the unit.
Location and access
Basements with stairs, attics and tight closets take longer than a ground-level utility room.
Permits and extras
Permit fees, expansion tanks, pans, drains and new shutoffs add to the total.
Utility or manufacturer rebates may apply to some efficient models, so check before buying. Want your real number? Call (215) 714-6692.
Installing in Horsham's mix of home ages
Census estimates for 2020 to 2024 give Horsham Township a median build year of 1980, with about 2,600 of roughly 10,079 housing units dating from the 1980s. About one in five units predates 1960. These figures are survey estimates with margins of error.
What that means for an install: houses from the 1970s and 1980s often have a basement heater on a metal flue. Their copper supply lines are usually in decent shape. Older houses may need new shutoffs and a venting update. Heating data shows about 4,000 occupied homes on utility gas and about 3,700 on electricity, so both setups are routine here.
If you are replacing a heater that has already failed, our water heater replacement page covers the same-day side of things. For new fixtures that change your hot water demand, see our plumbing installation service.
Nearby installs and scheduling
We serve Horsham and neighboring towns, including Maple Glen. Planned installs are scheduled by appointment, and the dispatch line is open around the clock if you want to book at night.
We do not install a gas appliance without checking the vent and shutoff, we do not use undersized wire to match a breaker, and we do not leave without showing you where the shutoffs and the relief valve are.
Questions about water heater installation in Horsham
A standard tank swap in an accessible spot often takes part of a day. Venting changes, a new circuit or a tankless conversion can take longer, and we tell you the expected time before work starts.
Yes, plumbing fixtures including water heaters are on the Township permit list, at 1025 Horsham Road. Ask Code Enforcement at (215) 643-3131 who files it. Inspections need 24 to 48 hours notice, so book the install date with that in mind.
Yes, if a gas line can be run to the heater and a proper vent path exists. We check both before we quote, because venting and gas piping drive the cost.
Size follows peak hot water use, not bedroom count. A 40 gallon tank fits many small households and a 50 gallon suits larger ones. We recommend a size after seeing your layout.
Often yes, if there is open air around it, enough ceiling height and a condensate drain. It also cools and dries the space a little, which some basements welcome.
We can, depending on the vent path, the gas or electric supply and the drain. Relocation is a plumbing and venting project, so we scope it before pricing.
Yes. Disconnecting, draining and hauling away the old unit is part of the installation.
Sources we checked
Local facts on this page come from these public pages. Plumbing work in Pennsylvania falls under the Uniform Construction Code, which adopts the International Plumbing Code (IPC) provisions, so ask Horsham Code Enforcement which edition applies before a permit is pulled. Rules and phone numbers change, so confirm with the office before you act.
