80kw Boiler – gas fired condensing
Our gas fired 80kW boiler is available in natural gas or for LPG applications. They are a high performance “A” rated ErP condensing boiler, and offer enhanced performance that exceeds the Part L building regulations for seasonal energy efficiency requirements.
This unit can be used for space heating, central heating, and domestic hot water production via a plate heat exchanger or indirect hot water cylinder or water heaters
Efficiency features: with a modulation ratio of 20:1, the automatic part load adjustment offers superb outputs down to 3.5 kw of heating output, which leads to better heat load matching of the system and lower fuel consumption and energy bills.
This energy efficient commercial boiler also has two stainless steel heat exchangers in one boiler as such, which ensures redundancy for your heating system; if one heat exchanger module fails, you still have up to 50% of your duty available. This feature can be vital in a commercial specification for a building that can’t be without some heat.
Wall Hung Gas Commercial Boiler
With the option of installing the boiler as a wall to wall solution or arranged inline on a free standing frame kit to offer enhanced performance.
We can provide a solution for every commercial specification, as we can cascade these high performance gas boilers up to 960 kW with automatic part load adjustment if so required.

80kW commercial wall-hung boilers
As each boiler (heat exchanger) has its own flue non-return valve, you can service either boiler heat exchanger module without shutting the space heating system down.
Our energy efficient gas boilers are fitted with fully modulating low NOx burners (Class 6 combustion levels) and fan for low carbon solutions.
R1K75 gas condensing boiler output and energy efficiency figures – Part L building regulations
The latest revisions to Part L of the Building Regulations that came into force on June 15, 2023, mean that all new wet central heating systems should be sized for a maximum heating flow temperature of 55°C (previously 75°C plus boiler flow temperature were allowed), as required by Part L1A, and preferably lower if possible to achieve the maximum condensing effect of boilers.
Thus, our gas boiler will produce 79.35 kW ( close enough to 80 kW for us) when the heating system flow and return temperatures are 50/30 °C. However, should you require more kW output, please look at the next size boiler up our 100kW boiler which again is available in natural gas or for lpg applications and offers superb outputs up to 106.8 kW.
The unit will also provide 72.83 kW at 80/60 °C if you have a process heating application that is not covered in the Part “L” building regulations.
Full Data is shown in the following –
This is detailed in our full manual which can be downloaded here –
Should you require a larger output gas boiler (we do up to 240 kW in a single boiler), then we do a full range, which is listed here.
“A” rated wall hung boiler – for commercial use or very large home heating applications.
Energy efficient condensing boilers up to 105.8 % at 100% heat input at 50/ 30°C
Stainless steel heat exchanger with 28mm diameter water ways that ensure the boiler from very low pressure drops, guarantees lower risks of clogging (more resistance to fouling up), greater thermal efficiency, and greater ease of cleaning.
Intelligent fault system: if the boiler has a fault, it will tell you exactly what has gone wrong, i.e., if the heating system pressure is too low, etc.
Pressure sensor to monitor system pressure as part of the intelligent fault system
Maximum heating operating system pressure = 3 Bar
Maximum heating operating system pressure = 0.3 Bar
Can be controlled by an “Opentherm” controller, such as a “Hive” or “Nest” type, which means you can control the boiler on the go from your mobile phone, tablet, or PC, just like our full range of smaller domestic counterparts that we supply.
BMS compatible with our 0-10 Volt free contact kit

80kW gas system boiler
Are these an 80kW gas system boiler? Yes, in that they have a pump (two actually, i.e., one for each heat exchanger module), but at this size of system boiler, we can’t fit an expansion vessel within the boiler casing, so one needs to be fitted to the pipework external to the boiler to make the unit a full system boiler.
Each heat exchanger module has its own flue exit. You can either individually flue each unit with a co-axial flue (80mm/125mm) should you wish to go room sealed up to 10 metres vertically or horizontally. However, if you use a split flue system, you can go up to 40 metres vertically or horizontally.
The last option is a common flue header for the boiler.
