How to choose a tankless water heater?

It can be difficult to choose the right model for you home. O’Connor Plumbing’s team of experts can help you make the right choice. To ensure that your unit is sufficient to meet your individual home needs, there are many factors to be aware of.

What devices are you using your hot water supply? Include washing machines, dishwashers, sinks, and showers. Add up the flow rate of each unit to determine how much power is needed.

It is also important to determine the type of heating element that you require. A gas-heated tankless water heater is not the best choice if your home does not have a gas line. The cost of installing a gas line to your home will most likely exceed any savings that you may have made by going tankless. A gas-powered unit will work faster and meet GPM requirements better than an electric one if your home uses gas.

An electric tankless water heater is a great choice if you are willing O’Connor Plumbing to wait a little longer for the heat to reach your home. These heaters are cheaper than gas, but they work better with smaller floor plans.
