Wall mounted electric commercial boilers -18kW to 96kW from Flexiheat UK

 

Our wall hung commercial range of electric boilers are 100% energy efficient and require a three-phase electrical supply at these sizes, with a wide range of outputs from 28kW to 96 kW. These commercial electric boilers can be used as the primary heating source for the hydronic heating system, or as reserve or top up heating for heating pump systems etc. They are not equipped with a pump or expansion vessel; these are by others. They can be used in a cascade boiler configuration for large output requirements.

Our electric boiler is a 100 percent energy efficient, intelligent modulating boiler that combines established commercial technology in a one-of-a-kind design to provide the client with one of the most advanced and efficient electric boilers on the market.

These  3 phase electric boilers can heat an indirect hot water calorifier / cylinder and a wet central electric heating system, whether they be radiators, underfloor heating, or a combination of the two, with the same simplicity and control as an oil or gas boiler.

These electric boilers have numerous advantages because they do not vent fumes from a combustion process and thus a flue or chimney system is not required, installation is inexpensive and easy to get done. The units are extremely quiet in operation, come with a three-year warranty, require very little maintenance, and more importantly require no annual safety check unlike gas and oil boilers do.

Wall mounted commercial electric heating boilers

These wall hung or wall mounted electric boilers are to commercial electric boilers for hydronic heating. On the control panel, the flow temperature can be regulated to a wide temperature range (20-90 ° C for radiator heating or 15-45 ° C for underfloor heating) in 1 ° C increments.

Technical features of the wall mounted electric boiler:

Top mounted flow and return heating system connections – 2 ” (50mm)  for the 64kW to 96 kW and 1 1/2″ (40mm) for the 28kW to 60kW output boilers

Bottom design fill / drain connection and valve

Boiler water temperature sensor (with electronic, digital display)

Boiler overheating safety thermostat, connected to circuit breaker / FI relay (manual boiler restart required)

Boiler body air presence sensor (automatic boiler restart after the air has been removed)

Low voltage safety switch (automatic boiler restart)

Boiler body with 4 mm thick  steel and high density thermal insulation – 20mm for the 28-60kW models and 50 mm 64-96kW output models

316L stainless steel electric immersions heaters with the possibility of switching in groups

Boiler control based on the PID principle, which ensures precise power control

Outdoor temperature-corrected operating temperature with the possibility to select and shift to pre-defined heating curves (with outdoor temperature sensor)

Boiler flow heating water temperature control

Indirect DHW tank temperature control, DHW tank with frost protection (switches on below 7 ° C)

Manual limitation of boiler maximum power in 3 power steps

Automatic boiler and heating system frost protection when switched off (switches on below 8 ° C)

Construction of the total output of the boiler as a power step with time offsets of 15 seconds- can be adjusted to 220 seconds depending on the system requirements

Boiler body pressure test during production, even after welding the boiler body and complete assembly of the boiler

Boiler electrical insulation test (500 V) at the end of the boiler manufacturing process

10-year warranty on boiler body welding quality or water leakage

36-month warranty on the boiler’s built-in electrical components

Digital and modular heating power control between 0-100%, according to which the number and power of the heating groups and / or heating inserts are switched on or off automatically according to the current heat demand. Thanks to the intelligent PID control, the electric boiler only operates at maximum output for higher heating or domestic hot water capacity requirements.
