A water heater is a perfect choice to face cold weather. There are some options, such as indirect water heaters or tankless water heaters. However, what is an indirect water heater? This water heater is a good investment when it comes to comfort. It has some good advantages and also disadvantages. Here is the complete guide on indirect water heaters that you should know.
What is an Indirect Water Heater
Indirect water heaters have been used for decades now. People have been using these units to gain comfort from their homes. It might cost slightly more than the other kind, but the advantages are far greater.
With the growing concern about energy savings and cost, using an indirect water heater is gaining popularity.
This phenomenon happens because using an indirect water heater proved to be a cost-saving and energy-saving action. The unit will provide valuable service while using less energy.
This water heater is insulated storage that holds a spiral heat exchanger. It is easier to say that this is a tank-in-a-tank water heater.
Indirect water heaters use your home’s main heating system to heat the water. They differ from regular water heaters because they don’t heat water directly. Instead, they use a boiler or furnace to heat water, warming up the water in the tank.
This way, the same system that keeps your house warm can also give you hot water, making it a smart choice for saving energy.
These water heaters are connected to a boiler, which does the hard work of heating the water. This setup can be really efficient, especially if you already have a heating system. It’s like getting two uses out of one machine – heating your space and water.

Indirect systems are great because they use less energy and can last longer. From my experience installing these systems, I’ve observed that they often outperform traditional models in terms of durability.
Stainless steel tanks, for instance, resist corrosion better than other materials, leading to fewer replacements over time, which means more savings in the long run. As an installer, I can attest to these systems’ added reliability, especially in homes with existing heating systems.
Disadvantages of Indirect Water Heater
Indirect water heaters have many advantages, such as energy and long-term cost savings. However, as someone who has worked with these systems extensively, it’s essential to be aware of their potential inefficiencies.
For instance, when the heating system is less active in summer, these heaters may become less efficient since the boiler must still operate at a fraction of its full capacity. In one instance, I had to advise clients to adjust their boiler’s summer settings to avoid excessive energy consumption.
- Inefficiency of its Heat Transfer
The indirect water heater system relies on an efficient heat transfer mechanism between the boiler and the tank. However, in my experience, even well-insulated tanks can lose efficiency during extreme cold spells.
This inefficiency stems from the boiler’s struggle to maintain a consistent temperature across the heating system and the water supply, which I’ve observed can result in higher operating costs during winter.
- Complexity
The indirect water heater uses two tanks in its components. This makes it difficult to install the unit easily. An expert is required for the installation.
- Difficult Setting
The water in both cold and hot tanks is not mixed. This fact will make the water control difficult since it has a different thermostat setting.
| Indirect Water Heater Considerations | Description |
|---|---|
| Cost Efficiency | Generally cost-effective if you already have a boiler, but installation can be expensive. |
| Durability | Stainless steel tanks tend to last longer, reducing replacement frequency. |
| Summer Operation | Less efficient during warm months when the heating system is underutilized. |
| Maintenance Needs | Reduces overall energy consumption by using a single heating and hot water system. |
| Environmental Impact | Reduces overall energy consumption by using a single system for heating and hot water. |
Why are Indirect Water Heaters so Expensive
Indirect water heaters cost far more than the other kinds. This happens because this water heater needs to be appropriately installed, which is complicated work done by the contractor and installer. Hence, usually, the water heater is installed by a professional.
Before using the unit, you must prepare the water heater’s spot. This will include the work of the contractor. The installation itself will include the complex work of trained installers. This is what makes the cost relatively high.
In addition, the cost of the unit itself is not cheap. This will add to your bill if you use an indirect water heater. However, it is said that the maintenance of the unit will not cost much since it could last longer than the other kind of heater.
You need to consider these things before buying and installing the unit at your home. You will get the best results, but at a fair price too.
Conclusion
Hence, the information regarding what is an indirect water heater. It is an excellent option to use in cold weather. It will bring comfort to your house. Be mindful that in purchasing or using this unit, you need to understand it first. Therefore, you will get more advantages than disadvantages.
