Brad gets this call a lot: a family keeps running out of hot water. Everyone's showering in shifts. The last person to go in the morning gets the cold one. Sound familiar?
That's actually what happened with one of Brad's customers here in Paso Robles. The existing tank heater simply couldn't keep up with the family's demand. Brad walked them through their options, helped them choose a tankless water heater sized correctly for their household, and installed it without a hitch. No more cold showers. The family now has hot water on demand — as much as they need, whenever they need it.
That's the kind of difference the right water heater installation makes. Not just swapping one unit for another, but actually solving the problem.
Tank vs. Tankless — Honest Comparison
This is the question we get most often, and there isn't a single right answer. It depends on your household, your existing plumbing setup, and how long you plan to stay in the home.
Traditional tank heaters cost less upfront and are simpler to install. A modern tank unit is significantly more efficient than something from 2010. For smaller households or rental properties, a tank often makes the most sense.
Tankless heaters heat water on demand — only when a tap is open — which cuts water heating costs by 20–30% for most families. They also last considerably longer (20-plus years vs. 10–12 for a tank). The upside of unlimited hot water is real, especially for households with three or more people. The trade-off is a higher upfront cost and a slightly more involved installation.
Brad will run through the numbers with you during the service call. He's not going to steer you toward the more expensive option if it doesn't make sense for your situation.
Brands We Install
4G's installs water heaters from Bradford White, Rheem, A.O. Smith, Rinnai, Navien, Noritz, and Takagi, among others. We keep relationships with local supply houses throughout San Luis Obispo County, which means we can typically source your unit same-day or next-day rather than making you wait a week.
One Thing Most Paso Robles Homeowners Don't Think About
Installing a new water heater in Paso Robles without addressing the hard water is a short-term fix. The same mineral deposits that destroyed the last unit will start attacking the new one from day one. A water softener installation paired with your new heater can add years to its life and improve the performance of every water-using appliance in the house.
It's not something we push on everyone, but if your last unit failed earlier than it should have, it's worth the conversation. 4G's installs water softeners and can bundle it with the water heater installation if it makes sense for your home.

Paso Robles Water Heater Installation FAQs
Most tank water heaters last 10 to 12 years in Paso Robles, though hard water can shorten that. If your unit is approaching or past that age and showing signs like inconsistent hot water, rumbling noises, rusty water, or leaking around the base, replacement is worth a serious conversation. Catching it before it fails completely gives you time to choose the right unit rather than making a rushed decision.
A tank heater stores a set amount of hot water and keeps it heated continuously. A tankless unit heats water on demand only when a tap is opened. Tankless units cost more upfront but use less energy, last longer, and never run out of hot water. For families in Paso Robles dealing with multiple people showering in the morning, tankless is often the better long term fit.
Most installations are completed in a single visit. Brad removes the old unit, installs the new one, makes all connections, and tests everything before leaving. You have hot water the same day in almost every case.
Yes. All water heater installations require a permit through San Luis Obispo County. 4G's handles that process for you. Unpermitted water heater work can create problems when you sell your home or file an insurance claim, so we do it right every time.
It does. The mineral content in Paso Robles water accelerates sediment buildup inside tank heaters and scale buildup in tankless heat exchangers. If you are replacing a unit that failed earlier than it should have, it is worth talking to Brad about a water softener installation at the same time. It can significantly extend the life of your new heater.
4G's installs water heaters from Bradford White, Rheem, A.O. Smith, Rinnai, Navien, Noritz, Takagi, and others. Brad will recommend the right brand and model for your household size, existing plumbing setup, and budget rather than steering you toward whatever carries the highest margin.
Yes. 4G's provides a one year workmanship warranty on all water heater installations in addition to the manufacturer warranty on the unit itself. Brad provides all manufacturer documentation at the time of installation so you have everything you need for warranty claims down the road.
