I just replaced my hot water heater. I stumbled across this company online and read the good reviews. Price was much better than other companies, so I was skeptical. I called Saturday afternoon, confirmed online Saturday night, and the work was completed Sunday afternoon. I have been so impressed with the service from my phone conversation with Juan to the installation by Alireza. Now I can only hope that the product is as good as the price, technicians, and customer service.

Finally, purchased today, scheduled installation over the weekend. For comparison I have checked with Home Depot and they quoted $2200 +tax. Rheeem 50 Gallon power vent $1489 is the item they will install, so roughly $700 installation fees. They won’t return the old one. Not sure about Costco pricing, they have $300 Gift Card. I don’t think anyone else would sell less than Go Lime. Thanks.

I just had Go Lime install my new hot water tank, and everything went great. No issues at all, and you can't beat the price. Some people complained about the fan on the hot water tank being super loud, but I don’t have that issue at all. In fact, it’s quieter than my old tank

A tankless water heater doesn’t store hot water. Instead, it heats water on demand as it flows through the unit. This means you get an endless supply of hot water and don’t waste energy keeping a tank full. To explore which system is better for your home, check out our blog on Tank vs Tankless Water Heaters
The right size depends on how many bathrooms or hot water appliances you’ll be using at the same time. Our experts can help you select a unit that matches your home’s peak hot water demand based on your usage and lifestyle.
Yes, tankless systems are typically 20–35% more energy-efficient because they only heat water when needed. Both Navien and Rinnai offer ENERGY STAR® rated models that help lower your utility bills.
