How does an indirect fired hot water heater work?

Have you tried setting down the temperature on the aquastat and circulator control that use hot water from the steam boiler to heat the water in the indirect-fired hot water tank?

What should be first hour rating of indirect water heater?

Most indirect manufacturers rate their tanks at varying BTU/Hr inputs. For example, a 30-gallon tank paired with a 160K boiler may yield the same first hour rating as a 60-gallon tank and a 90K input boiler. Manufacturer’s specs are the place to start. Every water heater should have a mixing valve, correct? Absolutely!

Is it safe to drain an indirect water heater tank?

Watch out: what you describe may be unsafe; that is, if you drain the indirect water heater tank but leave its heating coil hooked up to the heating boiler and the boiler running, the tank may be damaged; I would not do that without first checking with the manufacturer.

Do you need a vent for an indirect water heater?

As the tank itself uses no power, the heater doesn’t need any sort of venting. An indirect heater can use just about any type of power, from gas to solar, as it uses an external device to heat the water. You will need to set the boiler up as a separate zone when connecting it to a heat source.

Can a boiler be used as an indirect water heater?

If you’re using a boiler to heat your home, you can use it to efficiently heat your water too. Bradford White’s indirect water heaters use many of the same technological advances and quality features of our electric and gas water heaters to produce a very efficient, effective hot water solution for your home.

Where are indirect fired hot water heaters located?

Indirect fired water heater tanks for domestic hot water, such as the SuperStor TM are usually located close to the heating boiler and will have both cold and hot water lines leaving the tank to supply the building with domestic hot water and a loop of piping that runs between the [usually the] bottom of the tank and a nearby heating boiler.

What’s the difference between a direct heater and an indirect heater?

Meanwhile, an indirect heater can provide unlimited hot water per minute up to as many gallons as the tank can hold. In both cases, you will have to rely upon an energy cost to maintain water temperature. This cost largely depends upon water demand and how well insulated the indirect heater’s tank is.

How does an indirect water heater reduce heat loss?

Reduced heat loss — An indirect water heater is very well insulated and loses very little heat during long stand-by periods (at night or while you’re away). A gas water heater is always losing energy up the chimney. High performance — The performance of an indirect water heater is a direct result of the boiler it’s connected to.
