Water Heaters questions, answered by experts

You have more options for water heaters than ever before. The best one for your home depends on your hot water usage and budget. Some of the more common types of water heaters are the conventional gas heater, a heat pump water heater, or a tankless heater for smaller homes or those with less water demands. Some uncommon types are solar and point-of-use systems. Some homes may have a combination of two units, such as a large heat pump heater and a backup point-of-use system.

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

There are pros and cons to tankless water heaters. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact. On the other hand, they cost about twice as much to install as traditional tank water heaters and are more limited in terms of flow rate.
