Central Heating Systems and Boiler Rooms
Installation of central heating plant with condensing boilers, cascade systems, cylinders and pump sets.
The boiler room is the space in a building that consumes the most energy and is neglected the most. Set up correctly, it delivers the same comfort with noticeably lower fuel consumption.
Several small boilers connected in cascade instead of one large boiler run far more efficiently at part load and do not leave the building without heat in the event of a fault. In mid-season, a single boiler coming on is enough.
For condensing boilers to deliver their promised efficiency, the return water temperature has to be low enough. In an installation running at high temperature a condensing boiler is not much more efficient than a standard one. That is why we assess boiler replacement together with the operating temperature of the installation.
The flue, the ventilation and gas leak safety are not negotiable in a boiler room. We do not commission a plant without ventilation openings that comply with the regulations and a gas detection system.

How we work
Calculation
The heat loss of the building and the hot water demand are calculated.
Design
The number of boilers, the hydronic schematic and the flue solution are determined.
Installation
Equipment, pipework, flue and safety devices are installed.
Commissioning
Combustion is adjusted, efficiency is measured and control scenarios are trialled.
Training
Operating personnel are trained in use and emergency procedures.
Common questions
Is switching to a condensing boiler always worthwhile?
If the return water temperature of the installation is low, yes, the gain is clear. In old radiator installations running at high temperature the gain remains limited. That is why we address boiler replacement together with system temperature and control strategy.
What does a cascade system mean?
It means operating several small boilers together instead of one large one, bringing them on in sequence as demand requires. Efficiency is high at part load, and heating continues even if one boiler fails.
What is weather compensation?
It is the automatic adjustment of the flow water temperature according to the outdoor temperature. In milder weather cooler water is circulated; comfort is more stable and fuel consumption falls.
Which safety measures are mandatory in a boiler room?
Adequate ventilation openings, gas detection with automatic shut-off, a suitable flue solution and safety valves are the essentials. All of these are checked before commissioning.
