Modular boiler gives 1mW in 1m2
Contractors working in city centres, particularly in London, often have to negotiate cramped plant rooms which are not easily accessible. This means any solution that can make their job simpler, is welcome. Simply put, the more compact the boiler, the better
L
ast month British-based manufacturer, Hamworthy Heating launched a product that could
provide a solution. The Upton boiler, so named after a town
in Dorset (which coincidentally is how all of Hamworthy’s boilers are named) is a modular floor-standing boiler with 1mW output in a footprint of just 1m2
.
Stuart Turner, Hamworthy’s national sales manager, told guests at the launch: “The Upton can be transported in a van, so it’s clearly an ideal solution for inner cities and district heating installations.” The Upton, which has been in development for four years has taken into account responses from a target audience to gauge what they wanted to see in the boiler. And just how compact is it? Well, let’s just say you can fit 245 Upton boilers in a tennis court or 9,175 in Wembley stadium.
The features and benefits
The 6-bar rated floor-standing condensing boiler range has a gross seasonal efficiency of 97% and is available in 18 different models with outputs ranging from 100 to 1050kW.
A modulation of 5:1 per module
increasing to a total of 15:1 in a 3-high stack allows closer control of the output, saving on fuel bills and reducing
emissions.The vertically stackable design of the boiler modules allows flexible options where space is a challenge such as in new builds, city centres and packaged plant rooms. The precision-engineered sectional aluminium alloy heat exchanger at the heart of the boiler is characterised by a low water content. Heat transfer properties and even heat distribution throughout the heat exchanger allow a quick and efficient response to changes in heat demand. The Upton’s pre-mix burner enables

further fuel savings and environmentally- friendly low NOx emissions of <40mg/kWh. With low noise output, it is also an option for plant rooms adjoining quiet areas such as hospitals, offices and classrooms. Edward Swift, product manager at
Hamworthy Heating said: We’re pleased to see the outcome of years of development and testing. We’ve incorporated a lot of customer feedback to bring the features our customers need. To aid the design, the Upton boiler has water and gas connections in the same position across the range, regardless of output. This means that even if a project’s requirements change, models can be easily swapped with minimal effect to pipework and plant room design.” Delivered fully assembled, the Upton also benefits from an air inlet filter to maintain particle free air for clean combustion, providing long-term protection.
Condensate traps connect from each boiler module to simplify pipework and servicing, as condensate only gathers in one spot that needs to be drained. The combustion analyser point is at the front of the boiler for accessibility during maintenance.
The boiler also has a Siemens LMS
controller allowing close control of the individual boiler modules. This enables sequencing of an additional 15 boilers in a

the complete solution in mind. They can be installed before the boiler is put into place and come with new features such as a connection for pressurisation units and flushing point. All dirt collects in one spot and can be easily flushed from the pipe kit, reducing servicing time. Along with the integrated non-return valve to stop combustion gases entering non-firing boilers, they facilitate cascade arrangements for installations up to 4.2mW. An optional low loss header with
integrated air and dirt separator specifically designed for the Upton boiler can provide further benefits in terms of system water flow, cleanliness, circuit separation and performance.
