What is a Tankless Water Heater

As the name suggests, tankless water heaters have no storage capacity. They have a powerful heater that quickly warms the water when it senses circulation. There are electrical tankless hot water heaters readily available, but most are gas or propane-fired systems with a burner or heating elements, heat exchanger, controls, and a venting system. The unit’s heater fires up the burner when it senses water circulation. The heat exchanger then warms the water as it heads to whichever fixture called for it.

Are Tankless Water Heaters Gas or Electric

On-demand water heater systems can be both. You can purchase systems that can operate on either gas or electricity. You will want to install any electrical on-demand style water heaters near a 220V power source and are best run on an electrical circuit with a 200amp main breaker.

Tankless gas water heaters can operate efficiently on either natural gas or propane and are typically more powerful in their water heating abilities than electric tankless water heaters, providing you with instant hot water.

How Tankless Water Heaters Work

Tankless water heaters heat water directly without the usage of a storage tank. When a hot water tap is turned on, non-heated water enters through a pipe into the water heating system. Either a gas burner or an electrical component heats the water. Because of this method of heating water, tankless hot water heaters provide a continuous supply of warm water.

With a tankless water heater, you don’t need to wait for hot water anymore; you can get it on-demand. Nevertheless, the lower output from a tankless water heater tends to restrict the flow rate to your fixtures (which usually is not an issue as many systems have one heater per fixture or component).

Are Tankless Water Heaters More Energy Efficient Than Traditional Water Heater Systems for the Home

Electric tankless water heaters tend to have very high efficiency, with greater than 98% of the energy provided to the devices utilized to heat the water. Over time, this can add up and save on energy and expenses for many years to come! On the other hand, tankless gas-fired water heaters typically have an energy score of much less, with an energy utilization of less than 85%.

It’s essential to bear in mind the quantity of water that can be heated up utilizing a tankless system (0.5 to 2 gallons per minute for a single point heating unit as well as 5 – 10 gallons per min for a whole-house device). When thinking about which system might be ideal for a building, this is essential.

In cool environments, with cold outside temperatures, it’s even more difficult for the heater to supply the warm water into your home requires. Customers in cold climates will require a tankless gas water heater since electric kinds do not carry out successfully in freezing temperature levels.

What Are the Costs Associated with Owning a Tankless Water Heater

The upfront costs of a tankless hot water heater are above that of a conventional storage water heater. However, tankless water heaters will generally last considerably longer and also have reduced operating and also energy costs, which could offset its greater price point.

Buying an on-demand or tankless water heater today in the year 2020 will cost you anywhere from $1,500 to $3,000 for installation costs. The cost of a tankless water heater does go beyond $3,000, but that starts to get out of range of the average price.

When to Service your Tankless Water Heater

The upkeep and maintenance of an electric tankless water heater is extremely straightforward. Apart from making sure that the inlet filter that protects against big particles from going into the system, is clear of obstructions every couple of months, no other upkeep is typically called for.

Also, if you have a leaking water heater, maintenance and repair are suggested as soon as possible as well. It is always in your best interest to have the situation analyzed by a professional if you have a water heater leaking or think you may need to repair or replace your water heater for whatever reason!

One of the really nice things about a tankless water heater and doing maintenance on or replacing it is; opposed to other types of water heating systems, you don’t have to drain the water heater tank! Which, if you have ever tried to drain a water heater tank with your standard garden hose (which is the only option most people have as the water heaters are indoors and need to be drained to the exterior of the home), you know it can take some time and be problematic if you’re unlucky enough to have any trouble while draining it.

On the other hand, propane and natural gas tankless water heaters need an annual inspection and servicing to ensure safe fuel combustion and that the unit is still running correctly. On the occasion of a breakdown, electric tankless water heaters tend to be a lot easier to diagnose, repair, and also to troubleshoot.

Tankless Water Heater Sizing Guide

For the unit to adequately and effectively satisfy your hot water needs, a tankless water heating system only needs to be large enough to satisfy your house’s hot water peak demands based on what fixtures need to be supplied such as running the dishwasher while taking a shower. Getting one that is too large will only result in needless energy expenditures.

Having a water heater that is too small will lead to not being able to generate sufficient hot water for your home’s needs. If a unit is too small for a system’s needs, you could get a blast of icy cold water if someone tries using a second or third fixture while someone is already showering. Many of you have probably also experienced this when the toilet flushes in the bathroom when you’re showering.

On the other hand, a water heater that is too big will end up being more expensive than necessary, given that you will likely be paying much more for the larger unit and it’s increased operating costs (although maybe helpful if you intend to upsize your house later).
