What is an indirect water heater ?
An indirect water heater is a type of water heating system that operates in conjunction with a separate heating source, typically a boiler or a solar thermal system. Instead of directly heating water, an indirect water heater uses the heat generated by the primary heating source to indirectly heat the water stored in the tank.
Here are some key features and benefits of indirect water heaters:
Operation: Indirect water heaters feature a heat exchanger within the tank. The heat exchanger transfers heat from the primary heating source (boiler or solar system) to the water stored in the tank. The heated water remains separate from the heating source fluid, providing clean and safe domestic hot water.
Efficiency: Indirect water heaters are known for their high energy efficiency. By utilizing the heat generated by the primary heating system, they can efficiently heat the water while minimizing energy consumption.
Versatility: Indirect water heaters are compatible with different heating sources, including gas boilers, oil boilers, and solar thermal systems. This versatility allows homeowners to integrate them into their existing heating systems seamlessly.
Ample Hot Water Supply: Indirect water heaters typically provide a large storage capacity for hot water. This ensures a continuous and abundant supply of hot water for multiple faucets, showers, and appliances within the household.
Space Saving: Indirect water heaters are often designed to be compact and can be installed in small spaces, such as utility rooms or basements. They do not require a separate burner or fuel supply, saving space compared to traditional standalone water heaters.
Longevity: Indirect water heaters are known for their durability and long lifespan. Since they don't have a burner or fuel combustion within the tank, there is less wear and tear on the unit, contributing to extended durability.
Cost Savings: By utilizing the primary heating system, indirect water heaters can help reduce energy costs compared to standalone water heaters. They are particularly beneficial when paired with energy-efficient boilers or solar thermal systems.
Indirect water heaters are popular choices for homeowners who already have a boiler or solar system in place. They offer efficient, reliable, and ample hot water supply while utilizing the heat from the primary heating source. When considering an indirect water heater, it's important to consult with a professional plumber or heating specialist to ensure compatibility with your existing system and proper installation.

How Many gallons of hot water does a regular household use ?
Shower 20 gallons
Bath 20 gallons
Shaving 2 gallons
Hands and Face Washing 4 gallons
Hair Shampoo 4 gallons
Hand Dish Washing 4 gallons
Automatic Dish Washing 14 gallons
Food Preparation 5 gallons
Wringer Clothes Washer 26 gallons
Automatic Clothes Washer 32 gallons
Notes:
a) Estimate unusual peak draw demand. Whirlpool baths, hot tubs, and mutltiple head showers require large
quantities of hot water in a short period of time. Contact fixture manufacturer for quantity of water required.
Generally speaking, these circumstances can only be met with larger storage volumes.
b) Domestic Water Temperature. Most residential usage will be satisfied with 119ºF water, the temperature
setting recommended by the Consumer Product Safety Commission. Some applications such as laundry and
dishwashers may require a higher temperature.
Ratings can be improved by increasing Techtanium thermostat setting and using a mixing valve to temper the
hot water to the proper temperature. When temperatures greater than 119ºF are required, use a mixing valve at
the outlet of the water heater or anti-scald fittings at point of use.

Maintenance of new Techtanium water heater :
To ensure efficient and safe operation, DHT recommends the servicing of the heater by a competent service technician.
Lime or Sediment Buildup (Every 6 months)
To reduce the buildup of lime or sediment it is recommended that the tank be flushed every six months.
1. Drain the tank through the drain valve at the bottom of
the tank until the water is clear.
2. Inspect the tank for any deposits of lime or sediment.
3. Remove lime, scale or deposits using care not to damage the tank lining.
Temperature & Pressure Relief Valve (Every 12 months)
1. Before manually testing theT & P valve, make sure the valve is piped in a manner that will not cause harm or
damage any surrounding area.
2. Manually open the relief valve and allow it to flush out any lime or sediment deposits.
3. Allow the relief valve to snap shut, making sure the seal closes properly.
Magnesium - Anti-Corrosion Anodes (No longer than every 12 months)
The Techtanium Water Heater is provided with two magnesium anti-corrosion anodes, an upper and a bottom anode. Assessment of the condition of the bottom anode can be made by judging the condition of the upper anode. Removal of the anodes:
1. Shut off all power to the heater.
2. Close the domestic cold water supply valve.
3. Open the household hot water taps.
4. Attach a hose to the drain valve located at the bottom of
the heater and allow the heater to drain.
5. Unscrew the anodes.
EXAMINE THE ANODES AND REPLACE IF THE DIAMETER
IS LESS THAN .40 inches.
6. Replacement of the Anodes -- The use or P.T.F.E. tape is
recommended to ensure watertight connection of the
anodes.
Failure to inspect the anodes may result in premature
failure of the heater.
Benefits of having Indirect water heaters
Having an indirect water heater offers several benefits, including:
1. Energy Efficiency: Indirect water heaters are highly energy efficient. By utilizing a separate primary heating source, such as a boiler or solar system, they harness existing heat and transfer it to the water. This results in lower energy consumption and reduced utility bills compared to standalone water heaters.
2. Ample Hot Water Supply: Indirect water heaters typically provide a large storage capacity for hot water. They can store a significant amount of heated water, ensuring a continuous and abundant supply for multiple faucets, showers, and appliances throughout the household.
3. Cost Savings: By utilizing an existing heating system, such as a boiler, indirect water heaters can save on installation costs. There is no need for a separate burner or fuel supply, which can be a cost-effective solution for homeowners.
4. Versatility: Indirect water heaters are compatible with various heating sources, including gas boilers, oil boilers, and solar thermal systems. This versatility allows homeowners to integrate them into their existing heating systems seamlessly.
5. Safety: Indirect water heaters provide a safe and clean source of hot water. Since the water is heated indirectly through a heat exchanger, there is no direct combustion of fuel within the water heater, reducing the risk of gas leaks or other hazards.
6. Durability and Longevity: Indirect water heaters are known for their durability and long lifespan. Since they don't have a burner or fuel combustion within the tank, there is less wear and tear on the unit, contributing to extended durability.
7. Space Saving: Indirect water heaters are typically compact and do not require a separate burner or fuel supply, saving valuable space in utility rooms or basements.
8. Environmental Friendliness: Utilizing a primary heating source, such as a solar thermal system, for an indirect water heater promotes sustainability and reduces greenhouse gas emissions.
It's important to note that indirect water heaters require a compatible primary heating source, such as a boiler, for operation. Consult with a professional plumber or heating specialist to ensure compatibility with your existing system and proper installation. They can provide guidance on selecting the right indirect water heater for your specific needs and ensure optimal performance.
