How long do indirect water heaters last?

15-20 years
How long does an indirect water heater last? Indirect water heaters typically last 15-20 years.

Do indirect water heaters run out of hot water?

An indirect system is able to provide a high volume of hot water, so if you are running short it may be that the thermostat is set too low or is broken. It may also be the result of a bad circulator or circulator relay, or the unit could be air-bound and in need of purging.

What are the main advantages of an indirect hot water system?

The greatest advantages of the indirect water heaters are the significant reduction of flue losses. Less maintenance – no additional burners to maintain. Less cost – no additional venting required or fuel lines to run. Better performance – more available hot water with quicker recoveries.

Which type of water heaters save the most energy?

Tankless heaters can be 24-34% more energy-efficient than regular water heaters for households that use 41 gallons or fewer of hot water daily. Tankless heaters can be 8-14% more energy-efficient for households that use around 86 gallons daily.

How much does it cost to install an indirect hot water heater?

Indirect Water Heater Installation Costs Indirect water heaters cost $800 to $1,500 on average. An extremely efficient choice, they consist of a tank that pulls heat from a nearby boiler or furnace, rather than relying on an independent heat source.

How much does it cost to replace an indirect water heater?

Indirect water heaters cost $800 to $1,500 on average. An extremely efficient choice, they use a tank that pulls heat from a boiler or furnace rather than having an independent heat source. They’re basically just a tank you place next to your furnace.

How much does it cost to install an indirect water heater?

How do I size an indirect hot water heater?

Measure the GPM for each point of use, so you know how many gallons will be required during that peak demand time period. Total gallons × 0.85 will give you the quantity of hot water from the tank itself (on average for 120°F storage and 40°F inlet-temperature).

What is the difference between a direct and indirect heating system?

Quite simply, direct heating technology involves a bulk solid material coming into direct contact with a heating gas to change the final temperature of the material. Indirect heat transfer uses conduction, radiation or convection to achieve temperature change. …

What are the disadvantages of an indirect cold water system?

The main disadvantage of an indirect system is the risk of stagnation and contamination that comes with keeping a large quantity of water open to the atmosphere. Current water regulations require cisterns to be fitted with a set of components to ensure the water remains potable, i.e. drinkable.

What are the advantages of an indirect water heater?

Here are some of the advantages of using these heaters. When using an indirect water heating system, you can save a great deal of energy. Thanks to the system vastly reducing the amount of standby heat that is lost, an indirect heater proves to be far more efficient. This is also seen in the reduced running of the boiler or furnace.

How does an indirect heater use a furnace?

The fluid in the coil is heated and then cools off in the water tank, cycling back through to the heat source. Note that there is some confusion on how an indirect heater can use a furnace as its heat source.

Can a tankless water heater be used as an indirect heater?

Indirect water heaters have a limited hot water supply and require flushing, two issues a tankless heater is less prone to. Tankless water heaters can provide a certain number of gallons per minute (based on their rating) indefinitely.

How does a water heater work when connected to a heat source?

You will need to set the boiler up as a separate zone when connecting it to a heat source. The exchange piping usually contains non-potable water, which remains separate from the tank’s potable water supply. The water turns to steam at the heat source, with temperatures as high as 200 degrees Fahrenheit.
