Frequently Asked Questions

Many homeowners have questions about tankless hot water heaters, an energy-efficient alternative to traditional storage tank systems. Understanding these aspects will help you determine if a tankless hot water heater is the right choice for your home.

Tankless water heaters are designed to conserve energy and water alike, and many people upgrade to a tankless model to save money and to promote a healthier environment.

With a traditional tank-style unit, the water is heated in a tank and stored until it is needed. When water is needed, cold water must pass through to the bottom of the heater until the hot water pushes out from the top into the pipes. Comparatively, a tankless water heater goes into action the moment you require hot water, which is heated instantly and this saves energy. The process is triggered when the tankless unit senses the demand for hot water. This occurs when you use water in the shower, kitchen, or bathroom sink, or in the laundry room.

A tankless model will heat the water as it goes through the heat exchanger, which is activated by the incoming water as it flows through. When you turn the hot water tap off, the heat exchanger shuts down, saving energy and money. This is very different from more common tank-style hot water systems, which store large quantities of heated water in a tank.

Not only will a tankless heater save you money on your energy bills, but it will also save valuable space within your home since these systems do not require large holding tanks as their traditional counterparts do. This can free up some space in your garage or closet for extra storage.

Another feature that makes these new, more modern heaters very popular is the fact that it is virtually impossible to run out of hot water with a properly sized model for your needs. It only takes a few consecutive showers to deplete a traditional heater’s tank. Afterward, it is necessary to wait up to an hour before the tank’s contents are fully heated again so you can access hot water. With a tankless system, the supply is endless.

Tankless water heaters have benefits and drawbacks, depending on what is most important to you as a homeowner. Generally speaking, tankless heaters are more expensive to install but last longer, whereas traditional heaters may have a more economical up-front cost.

Absolutely! We can tie into your existing recirculation line or run what’s called a crossover install. If your home doesn’t have a dedicated return line you can install our crossover valve at the furthest fixture of your home and take advantage of our crossover mode.

You want to ensure your tankless heater is at 100% with all the hot water you need. That’s why it’s essential to have your tankless system tuned up with an annual maintenance service.

This detailed tune-up has three primary benefits:

Increased Efficiency & Money Saved
Minimize the Risk of Breakdown
Ensure Hot Water All Year Long

Tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only as needed. They primarily differ by the energy source they use. The main types are:

1. Gas Tankless Water Heaters

These heaters use either natural gas or propane as fuel.

2. Electric Tankless Water Heaters

These heaters use electricity to heat the water.

3. Propane Tankless Water Heaters

These are a subtype of gas heaters that use propane as the fuel source.

4. Hybrid Tankless Water Heaters

They combine the technology of tank and tankless water heaters.

The performance and energy efficiency of these heaters can vary based on factors such as fuel type, climate, local building code requirements, and safety issues.
