A planned water heater install is different from a rush job. You have time to pick the type, check the space and ask what the work involves. Our dispatch line is open 24/7 to book a licensed plumber for installs in Holly Springs, and we tell you the price before work starts.
If your current heater has already failed and the floor is wet, jump to our water heater replacement page instead. This page is for the planned side of the job.
Installs we plan with you
Most planned installs fall into four groups. Each one raises slightly different questions, so it helps to know which one is yours.
- New construction: a heater set while the walls are open, with the fuel and venting planned from the start
- Remodels: a heater moved or upgraded because a kitchen, bath or laundry layout is changing
- Upgrades: a working but aging tank swapped for a larger, tankless or heat pump unit before it fails
- Relocations: a heater moved from a cramped closet to a garage, or from an attic to the ground floor
Larger projects, such as adding a bathroom or rerouting pipes around the heater, may overlap with plumbing installation work, and we scope them together.
What each kind of install changes
The word install covers a lot of ground, so this table sets out what usually changes for each situation.
| Install type | What changes | What to sort out ahead of time |
|---|---|---|
| Same type, same spot | New unit, new connectors, new relief valve | Confirm size and check the old vent and drain pan |
| Gas tank to electric tank | Gas supply capped, vent removed, new dedicated circuit | Electrical panel capacity and breaker size |
| Tank to tankless | Larger gas line or heavier electrical service, new vent, wall mount | See tankless water heater service for what to ask |
| Tank to hybrid heat pump | Condensate drain, clearance for airflow, 240 volt supply | Open space around the unit and a place for condensate to drain |
| Moving the heater | New water, gas or electrical runs, new vent path | A permit conversation and a plan for the old hookups |
Tell dispatch what you have now, what you want and where it sits. We will book a visit and explain the price before any work begins.
Choosing capacity for your household
Capacity is about how much hot water you can draw in a busy hour, not just the gallon number printed on the tank. Count the people in the house, note any large soaking tub, and think about how often a shower, dishwasher and washing machine run at once.
The first-hour rating on the EnergyGuide label gives you that busy-hour figure. A family that showers back to back in the morning needs a high first-hour rating. A household of two with one bathroom may do well with much less. We compare your usage to the unit before recommending it, and we are happy to say a smaller heater is enough.
Space sets the upper limit. Ceiling height, door width and the floor area around the unit may rule out a tall tank, and a wide hybrid heat pump model may not fit a narrow closet.
Parts that belong with a proper install
A heater is more than a tank. These are the items we check or replace on a new install.
- A new temperature and pressure relief valve with a discharge pipe routed to a safe, visible spot
- A drain pan with a drain line where a leak could damage finished space below or beside the heater
- New flexible connectors or properly installed rigid piping on the hot and cold lines
- A shutoff valve on the cold inlet within easy reach
- A gas shutoff, a drip leg or sediment trap where required, and a leak test on every gas joint
- An expansion tank if your home has a closed plumbing system
- A vent that matches the unit and rises to the outside as the manufacturer's instructions require
Expansion tanks and relief valves
Water expands when it heats. In a home with a check valve or pressure reducing valve at the meter, that extra volume has nowhere to go, so pressure climbs. An expansion tank is a small pressurized vessel that absorbs it.
Without one, the relief valve has to do the job, and it may drip or discharge on a regular basis. We can tell you whether your system is closed by checking for a backflow device and measuring static pressure with a gauge on a hose bib. Not every house needs a new tank, but many installs do.
The relief valve is the last safety line. It must have a full-size discharge pipe with no valve, plug or cap, and it must stay accessible for testing.
Venting and combustion air for gas heaters
A gas heater burns fuel and needs two things: air to burn and a path for exhaust. A heater in a tight closet may not get enough air, and a vent with low spots or loose joints may let exhaust spill into the room.
Atmospheric vent systems rely on warm exhaust rising by itself. Power-vent and direct-vent models use a fan and plastic or special pipe to move exhaust out through a wall or roof. Which one you need depends on the model and the location, and we check the manufacturer's instructions for every unit we set.
A carbon monoxide alarm near the bedrooms is cheap protection for any home with gas appliances. Test it when we are finished.
Moving a water heater to a new location
People move heaters to free a closet, shorten the pipe run to the kitchen or get the unit out of an attic that is hard to reach. The move often costs more than a plain swap because the water lines, the vent, the gas or electrical supply and the drain all follow the heater.
A shorter run to the fixtures that use the most hot water means shorter waits for hot water at the tap, which is the common reason people give for relocating. We look at the proposed spot and tell you honestly if the cost is worth the benefit.
Permits and inspection
Georgia's minimum plumbing code is based on the International Plumbing Code (IPC) with Georgia amendments. Who issues permits depends on where the house sits.
- 1
Confirm the jurisdiction
Permit rules vary, so ask the City of Holly Springs at 770-345-5536 if your address is inside city limits. In unincorporated Cherokee County, the Development Service Center at 770-721-7810 handles it.
- 2
Have a licensed plumber pull the permit
In unincorporated areas, permits are issued only to state licensed technicians. Ask any plumber for their license details and verify them at the Georgia Secretary of State licensee search.
- 3
Install to the plan
The work follows the permit scope, including vent, relief valve and gas or electrical connections.
- 4
Schedule the final inspection
An inspector confirms the work before the permit closes. Ask the plumber when to expect the inspector.
Gas smell before or after any install
If you smell gas at any time, leave the building with everyone in it and call your gas utility or 911 from outside. Do not turn lights on or off and do not use appliances. Gas line inspection and new gas line work are separate jobs from a heater install, and we will not start either until the utility confirms it is safe. Dispatch cannot promise a response time on a gas smell.
What affects the cost of a water heater installation
We give a clear price before work starts. Insurance does not usually pay for a planned upgrade or a new install, so budget for it as home improvement.
Type and size of the unit
A standard tank, a tankless unit and a hybrid heat pump differ widely in cost, and capacity changes the number within each type.
New or changed connections
A new gas line, a larger gas line, a new circuit or a new vent path adds parts and labor.
Location
A moved heater needs new water, drain and vent runs. An attic install takes longer than a garage floor.
Required extras
Expansion tank, drain pan, a platform stand and updated shutoffs vary by house.
Permit and inspection
Where a permit applies, its time and fee belong in the plan.

Installs in Holly Springs and nearby towns
Cherokee County Water and Sewerage Authority (CCWSA) reports that its water is very soft, at 16 mg/L as calcium carbonate. That means scale is a smaller worry for a new tank here than for homes in hard-water areas. If your water comes from a different utility or a well, check that source's water report before assuming the same.
We install for homes in Hickory Flat and the surrounding area as well as in town. If a heater problem is part of a wider repair, see our water heater repair page.
Water heater installation questions
How long does a water heater installation take?
A like-for-like tank swap can often be finished in a single visit. Moves, fuel changes, tankless conversions and new venting take longer, and we tell you what to expect before work begins.
Do I need an expansion tank?
If your home has a check valve or pressure reducing valve at the meter, thermal expansion has nowhere to go, and an expansion tank is usually the right answer. We check the setup with a pressure gauge before recommending one.
Why does a gas heater need a vent?
Burning gas makes exhaust, including carbon monoxide. The vent carries it outside. A damaged or poorly sloped vent can let exhaust enter the home, so we inspect it on every gas install.
Can you move my water heater to another room?
Often yes. The move involves new water, drain, vent and fuel runs, and a permit conversation. We visit first, then give you a price.
What should I do if I smell gas near the heater?
Leave the building with everyone in it and call your gas utility or 911 from outside. Do not switch anything on or off. We schedule a licensed plumber after the utility says the home is safe.
Does my new installation need a permit?
Permit rules vary, so ask the City of Holly Springs at 770-345-5536 if your home is inside city limits. In unincorporated areas, call the Cherokee County Development Service Center at 770-721-7810.
