Gas boiler Navien Ace 24 k
KD Navien, a South Korean company, manufactures gas boilers called Navien Ice 24k (KyungDong NAVIEN).
Their products are widely distributed throughout Russia because they offer the best value in terms of both price and quality.
Units from the Navien concern cost about half as much as European models, while the equipment quality and performance characteristics are nearly identical. The boilers are made to run hot water and heating systems in commercial or residential buildings up to 240 square meters in size.
They pass through heat exchangers to create indirect heating of the hot water and coolant.
One of the model’s unique features is the turbocharging system, which produces air flow in amounts that match the pressure of the gas. A corresponding sensor is in charge of control; it responds to variations in the gas supply and commands the boost mode to be changed.

Boiler technical characteristics
Let’s examine the Navien Ace 24 K boiler’s specifications:
| Boiler type | Wall |
| Purpose | DHW, space heating |
| Type of fuel | Natural or liquefied gas |
| Efficiency | 90-92% |
| Thermal power | 9-24 kW (heating) |
Advantages and disadvantages of the model
The following are thought to be the benefits of the Ace 24 K gas boiler:
- High operating efficiency in conditions of unstable gas and water pressure.
- Based on the readings of the pressure gauge, you can monitor the tightness of the heating system.
- Large serviced heating area, it is possible to meet the hot water needs of a fairly large family.
- Control is carried out from a remote unit, which allows you to place boilers at a distance to reduce noise.
- Long warranty period.
- Power consumption is only 150 W.
Among the drawbacks are:
- High noise level.
- Standard pipe connections are clip-on, which does not provide adequate reliability.
- High price for the boiler itself and components. Despite the fact that it is half the price of its competitors from Europe, the costs of frequent repairs completely offset this advantage.
- It is necessary to use a voltage stabilizer.
There exist additional drawbacks that may be classified as design elements. When the system is installed or operated properly, these can be easily overcome.

Existing types
The Navien Ace 24 K gas boiler comes in two varieties:
The first design type features an open burner that releases combustion products (smoke) into the atmosphere.
Only an active exhaust hood (ideally installed in a separate ventilated room) is compatible with these boilers. The second variety features an insulated chimney and a closed burner with turbocharging.
These models are intended for installation in large-capacity residential or commercial buildings.
Furthermore, there are options for manufacturing:
The only difference between these varieties is the type of body color, which is white, silver, or gold, respectively. Their differences are purely ornamental; there are no structural alterations.

Device
The Navien Ace 24 K gas boiler’s design consists of a casing that houses the structural parts of the boiler:
- Expansion tank with a capacity of 8 l.
- Heat exchanger connected to gas burner.
- Circulation pump.
- Turbocharger fan.
- Three way valve.
- Devices for cleaning coolant, sensors, valves, gas supply control valve, etc.d.
The unit’s functions include heating the coolant and hot water that enter the system and coordinating the heating system’s circulation. Fresh portions of incoming water are heated by the burner, which activates automatically when the hot water level in the expansion tank drops.
The heating system’s coolant volume is increased in a similar manner.
It is feasible to identify leaks and fix them before they become serious by keeping an eye on the pressure.

For which rooms is it best suited??
The Navien Ace 24 K boiler’s power is intended for use in commercial, industrial, or residential settings with up to 240 square meters of space.
Premises are not subject to any particular requirements. Under challenging circumstances, with variable gas and water supply parameters, the units operated effectively.
The boiler itself, the heating system, and an unbroken power source must be installed correctly for the equipment to operate at a high standard.
Devices do not have issues with relatively small voltage fluctuations (up to 30). However, based on user reviews, it appears that the automation is unable to handle these fluctuations and needs a stabilizer.

Connection instructions
Anchor bolts are used to install the gas boiler. This puts unique requirements on the load-bearing wall: it can’t be a temporary partition made of plasterboard or fiberboard; instead, it needs to be able to support a load of roughly 30 kg and be constructed of sturdy building materials.
The installation site ought to be chosen so that maintenance and repairs can be done easily.
This should ideally be a separate, ventilated chamber where all required communications are conducted.
The primary tasks involve setting up a hot water distribution system and heating system; installing the boiler simply entails hanging it on the wall and connecting water, gas, power, hot water, and heating system (direct and return pipelines).
It is advised to use a different outlet that is unplugged from other users.

Homes can rely on the Navien Ace 24k gas boiler, a small, high-efficiency heating system, to reliably supply hot water and warmth. This post will walk you through its construction and functionality and provide detailed usage and installation instructions. Additionally, you’ll hear from homeowners who discuss their actual experiences with this model, emphasizing its functionality, usability, and any possible drawbacks. Our thorough overview and user reviews will offer helpful insights whether you’re thinking about buying this boiler or need assistance with your current unit.
Common malfunctions and their solutions
The control panel’s corresponding codes indicate operational errors with the boiler.
Among them are:
- E01. Boiler overheating. Occurs when the circulation pump fails, less often when the coolant filter is dirty.
- E02. Coolant circulation error. Indicates the formation of leaks in the system or the boiler itself (connections).
- E03. No flame on the burner. Indicates either failure of the ignition coils or lack of gas in the system.
- E04. Parasitic Flame. There is a gas leak or a spark jumps between the flame sensor and the ignition electrodes.
- E05, E06. Open circuit (short circuit) of the extract air temperature sensor (heating water). Occurs when the contacts close, most often due to the presence of condensation or other moisture on the board with the sensor.
- E07. DHW heating sensor failure. It is necessary to check the contact or quality of connection of the sensor.
- E08. Short circuit of the DHW heating sensor. Replacement of the sensor or the entire controller is required.
- E09. Fan failure (failure). Check the contacts and, if necessary, replace the fan.
- E10. Smoke removal system malfunction. Usually occurs due to blockage of the chimney by ice from condensation.
Other error codes appear in response to specific issues. The device’s user manual contains an exhaustive list.
