Things to consider before purchasing the tankless water heater with recirculating pump

If you are looking for an energy-efficient way to heat your water, a tankless water heater with recirculating pump may be a good option for you.

However, before purchasing one of these units, there are several things you should consider to ensure that it will meet your needs.

Rheem RTG-70XLP-1 Tankless Water Heater, Grey, Grey

1. The type of water heater

One of the biggest considerations is the type of water heater that is best for your home. Tankless water heaters are either gas-powered or electric, and both have their advantages and disadvantages.

Gas units generally provide more power than electric models, but they may be less efficient. Electric units may cost more to run over time because of the additional energy required to heat with electricity as opposed to gas, but they often have a lower upfront cost.

2. The amount of power you will need

Another factor to consider when purchasing a tankless water heater with recirculating pump is the amount of power you will need. The more power your unit has, the faster it will heat and deliver hot water to your home. However, some models are only rated for certain flow rates and may not actually deliver the amount of power you need.

For example, if you have a large family with several members showering at once or your home has several bathrooms with simultaneous uses of hot water, such as washing dishes and cooking, a tankless water heater may not be ideal because it won't be able to keep up.

3. How much space do you want to devote to a tankless water heater

In addition to considering the type of water heater and power you need, it's also important to think about how much space you want to devote to a tankless water heater.

If you are planning on storing your unit in a closet or cabinet, make sure that there is enough room for it before purchasing one that may be too large for your home.
