Are you thinking about replacing your house’s heating system? Lemax gas boilers, for example, are wall-mounted units that provide effective solutions that are gaining popularity among homeowners. These boilers fit neatly into contemporary living spaces without taking up any floor space, and they are made to reliably provide hot water and heating. It’s critical to comprehend the distinctions between single- and double-circuit Lemax boiler models and to speak with owners who have firsthand experience with these systems if you’re thinking about purchasing one.
Lemax is an expert in providing different types of gas boilers for homes, including single- and double-circuit models. The only purpose of single-circuit boilers is to heat water for hot water supply or home heating. They are perfect for smaller homes or apartments with moderate hot water demand because of their simpler design and frequently lower cost.
Conversely, double-circuit boilers, sometimes referred to as combi boilers, accomplish two things at once by heating the house and producing hot water. By doing away with the requirement for a separate water heater, this integrated system saves installation costs and space. Because they don’t require a storage tank and can provide hot water on demand, they are preferred for their energy efficiency and convenience.
Are you thinking about getting a Lemax gas boiler? Homeowner reviews emphasize a number of features of these boilers, such as their dependability, effectiveness, and simplicity of use. Many users value the small size, which minimizes visual impact and provides reliable heating performance all year long while fitting neatly into kitchen cabinets or utility rooms.
How the gas boilers Lemax are arranged
The Lemax wall boilers’ design is identical to that of every other contemporary gas boiler.
Principal components and nodes:
- Gas-burner.
- Primary heat exchanger.
- Gas valve.
- Three -way crane.
- Circulation pump.
- Turbuslennaya fan.
- Secondary plate heat exchanger DHW.
- Expansion tank.
- Electronic control board with a panel and display.
The coolant, also known as os, gets the most heating when it enters the primary heat exchanger.
The OM flow exits it and then enters the secondary plate heat exchanger, where it transfers some of its thermal energy to the water flow used in the domestic hot water circuit. The coolant is then partially combined with the return flow as it enters the three-way valve, achieving the temperature that the mode has selected.
A circulation pump makes sure that the coolant flows through the system, and the turbocharging fan keeps the combustion mode in the normal range and removes smoke.
A network of sensors controls and monitors the functioning of every structural component; upon detecting any malfunction, the sensors promptly notify the control board. The display shows an error code that can be used to identify the malfunctioning component.
The user manual that comes with the device has a comprehensive list of error codes.
Existing types
Lemax wall-mounted boilers are available in two varieties:
- Single-circuit. Capable only of heating the coolant for the heating circuit.
- Dual-circuit. They have the ability to independently prepare both coolant and hot water for domestic needs.
Dual-circuit units are the best option for residential use, but you should be aware of their limited performance.
It is preferable to select a single-circuit boiler and connect an external indirect heating boiler to it if a sizable amount of hot water is required for household needs.
Advantages and disadvantages
Wall-mounted boilers made by Lemax have the following benefits:
- Ability to provide power to the heating circuit and DHW supply (for dual-circuit models).
- Compact, visually attractive, making installation possible in the kitchen.
- Self-diagnosis system that detects and signals problem nodes.
- Wide range of models, allowing you to choose the optimal design and power of the device.
- Boiler parameters successfully compete with imported analogues.
- Long service life.
- The warranty period for the equipment is 36 months.
Among the drawbacks are:
- Dependence on power supply, it is especially important to protect the boiler from power surges or surges.
- Experts speak unflatteringly about the automatic security system, as well as about the quality of welding of steel heat exchangers.
The benefits and drawbacks of Lemax boilers can both be classified as design elements shared by all gas boilers. Performance is ultimately dictated by the quality of the installation and the operating environment.
What series and models are wall mounted?
The following series comprise Lemax wall-mounted boilers:
- Prime. A series of wall-mounted convection gas boilers. Presented in ten models with power from 10 to 32 kW. The line is a basic series of wall-mounted double-circuit units that allow you to heat your home and supply hot water for domestic needs.
- Prime-C. Wall-mounted condensing boilers. The lineup is represented by a single model with a power of 24 kW. Due to the presence of an additional source of thermal energy (condensation of water steam from the displayed smoke), the efficiency of the unit is considered to be 108%.
- Prime-ho. Single -circuit gas wall boilers that can only provide heating of the coolant for the heating circuit. 5 models are offered with a capacity of 20 to 32 kW. It is possible to connect various peripherals, for example, an external boiler.
Remote control of any series of wall boiler is possible with a smartphone application.

User manual
The owner does not need to take any extra steps in order for the boiler to operate. The control panel’s buttons can be used to change the temperature as needed. It is essential to have the device serviced and cleaned by a specialist at the conclusion of the heating season.
You are not allowed to use active chemical liquids; you can only wipe the exterior yourself.
If an expert from the service center performs any other work, you risk damaging the unit or losing the warranty.
The boiler must be fully disconnected from the mains (unplugged from the socket) prior to cleaning.
Lemax provides single- and double-circuit wall gas boiler models to accommodate varying heating requirements if you’re thinking about getting one for your house. Single-circuit boilers are perfect for smaller spaces or situations where hot water demand is restricted to one source at a time because they are made specifically for heating water. Conversely, double-circuit boilers are more adaptable for larger households because they can produce hot water as needed in addition to heating.
Owners value Lemax boilers for their space-saving compact design because it makes them smaller than conventional floor-standing models. This is particularly helpful in contemporary homes where maximizing available space is essential.
