Cost factor #1: Type & severity of repair needed
This may seem obvious, but the type of repair needed will have the biggest impact on the overall cost of your tankless water heater repair. Typically, this is due to the part that needs to be repaired and the length of time a repair will take, which translates into the cost you pay a plumber for labor.
A few common tankless water heater repairs (in order of least to most expensive) are:
- You’re noticing low water pressure $
- Your water heater isn’t producing hot water $$
- Your water heater is leaking $$$
If you’re noticing low water pressure, the fix could be as simple as using less hot water appliances at a time. However, if your water heater is leaking, this is usually a much more expensive issue, and will usually result in the complete replacement of your water heater.
Cost factor #2: The age of your water heater
If you have an older water heater (20+ years old), the cost to repair it will likely be more expensive.
This is because a damaged part in an older water heater will likely need to be replaced rather than repaired. Additionally, if you need a repair on an older system, there’s a good chance that there are several parts that need to be repaired/replaced, which will increase the overall repair cost.
If you have an older water heater and are needing a repair, our advice would be to speak with a technician about whether it would be more cost-effective to replace your water heater rather than repair it. You don’t want to continue to pour money into a heater that is going to break down or need more costly repairs in the near future.
Cost factor #3: The plumber you hire
In general, the more experienced a plumber is, the more they will charge for a hot water repair. However, this is not a cost you want to compromise on, as hiring an inexperienced plumber could result in more repairs or an entire replacement down the road.
When looking for a quality plumber, our advice is to find someone who:
- Has a verified license and insurance
- Has great reviews on sites like Facebook, and Google
- Will provide upfront pricing before any work begins
- Has solid guarantees on their work
This way you can ensure that your hot water heater repair will be done correctly and safely.
Cost factor #4: Whether or not you have a valid warranty
If your warranty is still valid, the cost of your water heater repair could be significantly less expensive.
Manufacturers usually cover the cost of any parts that fail due to a manufacturer error, called a parts warranty. Typically, parts warranties last anywhere from 2–10 years, depending on the manufacturer and whether or not you purchased an extended warranty.
However, a few things can void your parts warranty outside of that timeframe. Below is a list of things that can void your parts warranty:
- You have not invested in annual maintenance on your water heater by a licensed plumber
- Your water heater wasn’t installed according to the correct plumbing codes
- Your water heater was never registered with the manufacturer
- Your water heater has been repaired with off-brand parts
You can check to see if your water heater parts warranty is still valid by visiting your water heater manufacturer's website or calling the plumber who installed your water heater.
