A tankless water heater is a good way to go in your home. For starters, the hot water that is produced is endless.
When you turn on your system, it’s heating the water before it gets to your faucet. Whether you're filling your
bathtub or whether you have a family that is having three or four showers one after another, you can count on having hot water on demand.
A brand we recommend is the Navien high efficiency, condensing water heater. It’s one of the best tankless condensing water heater systems and has one of the highest efficiency condensing combination wall hung boiler units available. They hang on the wall, they vent directly out of your home through a wall. And they bring in combustion air from the outside, which makes it much safer, and you're not storing 40 to 50 gallons of water all the time. It's just 1 gallon, which is ready to go immediately on demand.
