Gas Tank Water Heaters
A common, cost-effective choice for homes already set up for gas. They recover quickly and run cheaply where gas rates are favorable. We confirm the venting and gas line are right for the new unit.
Need a new water heater? We install properly sized tank and tankless systems with upfront pricing, code-compliant installation, permits included, and same-day replacement available.
This is the first decision, and the right answer depends on your budget, your space, and how your household uses hot water. A tank heater costs less up front and suits most homes well. A tankless unit costs more to install but heats water on demand, never runs out, lasts longer, and frees up floor space. Here is how they compare.
| Tank | Tankless | |
|---|---|---|
| Upfront cost | Lower | Higher |
| Hot water supply | Limited by tank size | Endless, on demand |
| Lifespan | About 8 to 12 years | 15 to 20 years with care |
| Space | Takes floor space | Wall mounted, compact |
| Energy use | Heats and reheats a tank | Heats only what you use |
| Best for | Lower upfront budget | Long term value, space saving |
Neither is universally better. A larger family on a tighter upfront budget is often well served by a right-sized tank, while a household that hates running out of hot water, or wants the longest service life, tends to prefer tankless. We walk you through the trade-offs for your specific home before you commit.
Sizing is where a lot of installs go wrong. Too small and you run out of hot water; too large and you pay to heat water you never use. For a tank unit, size is about capacity in gallons and the first-hour rating, how much hot water it can deliver during your busiest hour. For tankless, size is about flow rate, how many fixtures can run hot at once.
As a rough guide:
| Household size | Often well matched to |
|---|---|
| One-to-two-person home | 30 to 40 gallon tank |
| Three-to-four-person home | 40 to 50 gallon tank |
| Larger household | 50 to 80 gallons or a high-flow tankless |
But the right size also depends on your peak demand, two showers and a dishwasher at once is a different number than a single bather. We size it to how your home actually runs, not a generic chart.
We install every common type, and help you match the unit to your home's existing setup.

Simple, reliable, and a good fit for homes without a gas line. They cost less to install than gas but can cost more to run depending on rates. We confirm the circuit can handle the new unit.
Gas or electric units that heat water on demand for endless hot water and a longer lifespan. They need the right gas line size or electrical capacity and proper venting, which we verify before installing so the unit performs as it should.
Highly efficient electric units that pull heat from the surrounding air. They cost more up front but can cut water heating bills significantly in the right basement setting. We will tell you whether your space suits one.
Tankless installation is more involved than swapping a tank, which is exactly why it pays to use a plumber who installs them regularly. A tankless unit needs:
An undersized gas line is the most common reason a tankless unit underperforms after a cheap install. We verify each of these before we quote, so the unit delivers the endless hot water it is supposed to.
Done right, a tankless heater runs 15 to 20 years and frees up the floor space a tank takes.
Replacement, rather than repair, is usually the right move when you see these.
If the unit is newer and the fault is a part, a repair may be the smarter spend, and we will tell you so; see our water heater repair page. When replacement is the better value, we give you the honest numbers and the options.
A standard replacement is usually a half-day job, and you get one local plumber start to finish.
Type, size, and a flat price in writing before the day, so there are no surprises.
And haul it away, so you are not left with it.
Venting and gas line on gas, circuit on electric, and bring anything up to code that the new unit needs.
Set the temperature, and pull the permit for inspection.
Confirm it heats correctly, then clean up and leave the space tidy.
Installation cost depends on the type and size of the unit and what your existing setup needs, venting, gas line, or electrical work to bring it up to code. A standard tank replacement sits at the lower end; a tankless install with line and venting work sits higher. We give a flat price in writing before the day. The table below shows typical ranges so you know what to expect.
| Service | Typical cost in the Harrisburg area |
|---|---|
| Water heater installation, tank (gas or electric) | $350 to $2,000 |
| Water heater installation, tankless | $2,000 to $4,500 |
| Water heater repair (when a fix makes more sense) | $150 to $600 |
These are typical ranges, not quotes. Your final price depends on the unit you choose and any code work your setup needs, and we put it in writing before installation day. If a repair would serve you better than a replacement, we will tell you that too.
A water heater installation is permitted, inspected work in most cases, and skipping that is a problem when you sell the home or file an insurance claim.
We pull the right permit and install to code, which matters more than usual in Harrisburg's older housing stock, where venting on a gas unit, an aging gas line, or an undersized electrical circuit can all need attention on a replacement.
For landlords and flips, code-compliant installation with the paperwork handled keeps the unit legal and the property rentable.
We handle the permit so you do not have to think about it.

A tank water heater installation typically runs about 350 to 2,000 dollars, and a tankless install about 2,000 to 4,500 dollars, depending on the unit and any code work your setup needs. We give a flat price in writing before installation day.
A tank costs less up front and suits most homes. A tankless costs more to install but heats water on demand, never runs out, lasts longer, and saves space. The right choice depends on your budget, space, and hot water habits, and we help you weigh it.
Roughly, a 30 to 40 gallon tank suits one to two people, 40 to 50 gallons suits three to four, and larger homes need 50 to 80 gallons or a high-flow tankless. But peak demand matters too, so we size it to how your home actually uses hot water.
A standard tank replacement is usually a half-day job. A tankless install, or one that needs venting, gas line, or electrical work, can take longer. We confirm the timeline when we quote.
In most cases, yes, especially a tank-for-tank replacement. If your old unit has quit, we keep common sizes available so you are not without hot water for long.
Most water heater installations are permitted, inspected work. We pull the right permit and install to code, which keeps the work legal and protects you when you sell the home or file a claim.
It can be, if you value endless hot water, a longer lifespan, and the floor space back. Tankless costs more up front and may need gas line or electrical upgrades, so we confirm your setup and give you the real numbers before you decide.
Yes, all of them, in tank and tankless form. We help you match the unit to your home's existing gas or electrical setup and your budget.
Replace if the tank is leaking, the unit is past ten to twelve years, or repairs are adding up. Repair if it is newer and the fault is a part. We give you the honest math either way.
Yes. A standard installation includes draining, disconnecting, and hauling away the old unit, so you are not left to deal with it.
