The manufacturers of tankless water heaters are marketing intensely to get people to believe that going “tankless” for hot water is the greatest thing since sliced bread.
The idea of “instant and unlimited hot water” is attractive to many homeowners, especially those with families and high water usage.
But the truth is, going “tankless” is not for everybody — nor is it appropriate for every type of home.
You may be able to find a deal on the actual equipment, but you will pay high rates for installation and incidental material for the installation.
Why? Here are just some of the major reasons:
- Most existing houses are simply not set up for this type of water heater. If your current hot water tank is in the attic or under the house or in a corner of your garage, you may have to move it to accommodate the tankless water heater — and that means moving all the piping and wiring that goes with it.
- Your existing pipes may be inadequate (read “too old”) to handle the output from the tankless water heater. And they may not be made of the proper material.
- If you currently have a gas water heater, the gas supply line may be too small for the tankless water heater, meaning the gas supply will be insufficient to actually heat the water as it should.
- Your electrical wiring may be insufficient to handle the requirements of the tankless water heater.
If you are building a home, generally your contractor can design the home to accommodate this type of water heater, but you will likely pay extra for that design. Most contractors prefer the easy method of installation — the one they have done hundreds of times before.
Because, you see, not all plumbers or contractors are qualified to install (or even repair) tankless water heaters. An installer should maintain a gas fitter’s license since gas piping, sizing, and installing may be required. If an unqualified technician works on yours, it could invalidate the manufacturer’s warranty on the product.
Before deciding on a tankless water heater for your home, get all the facts. Get someone to come out to your home and evaluate it to see if it is feasible. Learn about the various models available, and the pros and cons of each. Make sure this assessment includes:
- Cost of the water heater
- Plumber’s fees
- Incidental material for installation (pipes, clamps, valves, etc.)
- Electrician’s fees (if needed)
- Are you on well water?
