A tankless water heater heats water only when a faucet or fixture calls for it, rather than keeping a tank of water hot around the clock. For many households, that on-demand approach can reduce standby energy use and free up space where a storage tank once sat.
McVay Plumbing, Heating, Cooling & Electrical provides tankless water heater installation in Gibsonia, PA. Our team evaluates your home's hot water needs, fuel source, and existing plumbing before recommending equipment and planning the installation.
When to Consider a Tankless Water Heater
A tankless water heater is not the right fit for every home, but certain situations can make it worth considering. Common reasons homeowners explore tankless installation include:
- An existing storage tank that needs to be replaced
- Interest in reducing the energy used to keep stored water hot
- Limited space in a basement, utility room, or closet
- A remodel or addition that changes the home's hot water needs
- Running out of hot water with a storage tank that is undersized for the household
Hot water demand, fuel type, and existing connections all affect whether tankless is a good fit, so McVay evaluates the home before recommending equipment.
Tankless Water Heater Installation Services
Every home is different, so the right installation depends on how much hot water the household uses at once, the available fuel source, and where the unit will be located.
Sizing and Equipment Selection
Tankless water heaters are sized in part by how much hot water they can deliver at one time. Because each unit has a specific flow capacity, simultaneous use of several showers, faucets, or appliances can affect performance.
McVay reviews how many fixtures may run at the same time and recommends equipment based on the household's hot water demand.
Replacing a Storage Tank With a Tankless Water Heater
Switching from a storage tank to a tankless unit can require changes to gas lines, venting, electrical connections, or water piping. The exact scope depends on the existing setup and the equipment being installed.
McVay explains what the conversion involves and provides pricing before approved work begins.
New Tankless Water Heater Installations
Tankless units can also be installed as part of new construction, home additions, or larger plumbing renovations. Planning the location and required connections early can help the installation fit the home's layout and plumbing needs.
What to Expect During Tankless Water Heater Installation
McVay starts by evaluating the home's hot water demand and existing setup before recommending equipment. From there, we explain the installation scope and any changes required to accommodate the new unit.
- Initial evaluation: We review your household's hot water use, current water heater, fuel source, and installation location.
- Recommendation and pricing: We explain the recommended equipment, discuss the scope of any connection or venting changes, and provide pricing before we begin approved work.
- Removal of existing equipment: When replacing a storage tank, our team disconnects and removes the old unit.
- Installation: We mount the tankless water heater and complete the approved water, fuel, venting, and electrical connections.
- Final review: We test the unit, check its operation, and review the finished work with you.
The exact process depends on the equipment, fuel type, and existing connections.
Tankless vs. Storage Tank Water Heaters
Both types of water heaters have advantages, and the better fit depends on the household's hot water needs, available space, fuel source, and existing setup.
A tankless water heater heats water on demand and takes up less space, but its flow capacity limits how much hot water it can deliver at one time. A storage tank keeps a set amount of hot water available and is often simpler to install, but it uses energy to maintain the stored water's temperature.
If a storage tank is the better fit, water heater installation may be the right next step. McVay can explain the trade-offs based on your home, or you can review our other water heater services.
