Flexiheat UKCommercial Electric Boilers
Commercial electric boiler / Industrial electric boilers – are compact electrically powered heating devices designed for heating anything from large residential properties to commercial and industrial buildings, with a three phase, 400 Volt electricity supply. The boilers heat water, just like a gas or oil boiler, and this water is pumped around the building giving off its heat via heat emitters such as radiators, underfloor heating, unit heaters or trench heating, in what is normally referred to as a traditional ” wet ” heating system or a hydronic heating system. Needing no flues, these powerful electric commercial and industrial boilers are highly efficient solutions being over 99.5% energy efficient to suit many diverse heating needs.
Our commercial electric boiler range are efficient, reliable, and provide environmentally conscious central heating and domestic hot water (if so required) in large residential buildings,commercial spaces, commercial buildings or even industrial spaces with larger heating demands.
With the continual push to reduce carbon emissions and to accelerate sustainability within the commercial and industrial heating sectors, a commercial electric boiler, when coupled with a zero emissions electric source such as wind, tidal or solar generated environmentally friendly electricity, they are the perfect solution for a commercial or industrial heating system that is emission free, with green energy and not reliant on fossil fuels, helping businesses to manage carbon emissions.
There is also an argument for nuclear generated electricity to be classed as zero emissions or green energy, as no CO2 is added to the environment whilst producing the electricity to.
We have two ranges of commercial electric boilers –
- The Thermo Max range – this range has full BMS compatibility (ModBus or 0 to 10 Volt control) and is easy to cascade without any additional controllers – just a simple 2.5mm cable between boilers. We can cascade these units up to 5MW in heat output.
- Our Thermo Extra range, from 28kW to 96kW outputs, which can be wall mounted, or floor mounted and can also be cascaded, and has full BMS compatibility just like our Thermo Max range. This commercial electric boiler range can also be cascaded up to 10 boilers being ideally suited for large commercial applications.
Thermo Max Industrial & Commerical Electric Boilers Range – 120 kW to 500 kW
Thermo Max Electric Boilers
The Thermo Max range of industrial electric boilers are 100% efficient central heating boilers suitable for wet heating systems such as radiator, unit heaters or underfloor heating. The power output of this range is from 120kW to 500kW, with 8 models covering this range. They are suitable for heating demands with a maximum temperature of 90 Degrees C, and a maximum working water pressure of 6 Bar. The Thermo Max range of commercial and industrial electric boilers is designed to operate in sealed heating systems only – not open vent, and subsequently you should ensure that an adequate heating expansion vessel is installed.
The boilers are well made, for example the water heating chamber is manufactured from 4mm steel and tested to a hydraulic pressure of 8 Bar. The immersion heaters or heating elements used in these boilers are manufactured from stainless steel Incoloy 800, which ensures a long product life cycle. The outer casing is manufactured from 1.5mm steel and is finished with an electrostatic plastic coating,this robust construction ensures good durability and lower maintenance costs.
Features –
- 8 models within this range of commercial electric boilers- consisting of either a 120 kW electric boiler, 150 kW electric boiler,180 kW electric boiler, 210 kW electric boiler, 255 kW electric boiler, 300 kW electric boiler, 400 kW electric boiler, and finally a 500 kW electric boiler. They can also be used in cascade for large kW outputs. For example, two 500 kW electric boilers can be used to make as such “one” 1,000 kW electric boiler to heat large spaces.
- Cascading electric boilers has some benefits of redundancy and also better heat load matching to the heating system requirements to name just a few.
- They do not come with a heating pump or expansion vessel, and these should be sized according to your wet heating system requirements for your site.
- These commercial electric boilers can be used in a cascade installation – ensuring that larger power requirements can be satisfied – there is no actual limit of the number of boilers that can be connected together but we recommend a maximum of 10 boilers – thus up to 5 MW of output per cascade.
- These electric boilers have cutting edge specifications with either 7 step heating output control for the 120kW model or 15 step heating output control from the 150 kW to 300 kW models and 30 step heating output for the 400kW and 500kW models . This is referred to as PID regulation, and ensures that automatic modulation of the boilers power to improve heating system performance
to suit the heating systems requirements.
Technical Data for Thermo Max Electric Boilers
Please note as standard these boilers are suitable for continual running at a flow temperature of 90C maximum.
Electric Boiler Output Modulation
These Themo Max electric boilers have either 30,15 or 7 power output stages or heating output levels depending on commercial electric boiler model.
This is important to know – for example – the 400kW boiler can be set to a maximum output of 399 kw but also as low as 15 kW – as you can see from the below chart – Page 11 of the manual – in essence the boiler covers many different output requirements – thus you can set the maximum output of the boiler to say stage 25 – i.e. 339 kW maximum output, and the boiler will ramp up and down these heat output stages to suit the heating system requirements
kW output steps of our Thermomax commercial and industrial electric boilers for hydronic heating systems – 120kW to 500kW in single piece boilers or up to 5MW in cascade).
The boiler will also ramp up and down the above power levels to your set kW output , according to the heating system requirements
Thus, our 400kW and 500 kW electric boilers have a 30:1 turndown / modulation ratio , the 150kW to 300kW models have a 15:1 turndown / modulation ratio whilst the smalller 120kW commercial electric boiler has a 7:1 turndown ratio.
This means our maximum recommended cascade configuration of 5MW – would have an incredible 300:1 modulation ratio, which ensures close heat load matching and reduced energy consumption of the heating system.
Ultimately this electric commercial boiler range can cover many kW output requirements.
Control Panel
Our “X” panel is a “one and all” control panel – with all the options of weather compensation (an external temperature sensor is required) to improve heating system performance, and control of a DHW indirect cylinder all in one panel.
The electronic control panel has a frost protection system, that ensures if the temperature of the water in the boiler drops below 7 degrees C , then the boiler will automatically switch on the immersion heaters to ensure the water temperature is increased to 7 degrees to prevent freezing .This frost protection system works even if the boiler control panel has been switched off.
The control panel is conveniently situated on the front of the boiler, with no user controls are situated withing the boiler casing. Pump seized/ lock protection is also standard on this controller.
It is a touch screen panel (lcd display), that has various language options – English, German, etc

They are as standard wall mounted units; however, we can supply a floor mounting kit to make these electric boilers free standing floor mounted.
Floor mounting boiler frame kit for our 28kW to 96kW Wall hung electric commercial boilers, which converts the boilers into free standing floor standing electric boilers.
Whether it be for heating a larger home or when used in a commercial heating system, electric boilers are prized because they are easier to clean and service than gas or oil-fired boilers and normally benefit from lower installation costs and are often easier to install in small boiler rooms or hard to reach spaces.
They are also safer, as no carbon monoxide or any other combustion by products are produced by electric boilers and have silent operation when in use.
Commercial electric hot water boilers
There are always discussions with regards to – At what output does an electric boiler become a “commercial electric boiler” and should be referred to as a commercial electric boiler. There is no hard and fast rule for this, but generally in the boiler market any boiler with an output above 50 kW is generally referred to as a commercial boiler. At what point they stop being commercial electric boilers and become industrial boilers, is really down to your opinion, as yet again there are no hard and fast rules for this either.
Ultimately commercial electric hot water boilers , use electricity to produce efficient, clean and safe water heating for a central heating system via heating elements. This heating method is preferred by many because, since it lacks the element of combustion, it poses no potential complications or dangers with regards to gas piping (and the inherent dangers of a gas leak), venting of the products of combustion and thus the elimination of carbon monoxide poisoning. In the case of water heating for a wet heating system, recent developments in electric water heating technology has allowed for more rapid heating and more consistent temperatures for the heating system.
This range of Thermo Extra electric commercial boilers have seven power outputs, or steps, meaning the boiler will modulate 7:1 to suit the demands of the heating system.
You can also set the boiler to a maximum output level, and it will adjust its output up or down to match your desired setting.
Technical Specification –
Firstly the 28kW to 52kW models – so for example if you want a 50kw electric boiler, you have the option of just under at 48kW or just above at 52kW
Our 28kW to 52kW electric boiler range power output modulation steps – each boiler has 7 power output levels or steps.
Then the 56kW to 96kW models – so for a 100kw electric boiler demand, then either use the 96kW unit below or one of out Thermo Max 120kW units, set to a maximum output of 105kW ( stage 6) , so a “tad over” in output.
