Bespoke prefabricated heating solutions

Heating has been identified as a natural target for improvement as we work towards our 2050 net zero emissions target. While great strides have been made in well-insulated commercial buildings, finding suitable solutions to meet the requirements in the UK’s older building stock is a greater challenge. To address this, we are innovating with longer-term green gas retrofit solutions, including hydrogen boilers. But our condensing boiler range provides immediate opportunities for significant energy savings right now – and will likely continue to do so for the next decade.

Replacing any old or inefficient boiler plant with highly efficient low NOx condensing boilers remains one of the most practical, achievable and cost-effective means of driving down energy consumption, costs and emissions associated with heat. As a core component of the commercial plant room, the highly efficient operation of our condensing boiler range will continue to play a vital part in improving building energy performance and help make significant strides along the path to net zero.

Bespoke prefabricated heating solutions

Space and access limitations combined with time constraints are frequent hurdles to boiler installation. More recently, the need to prioritise on-site safety has presented new challenges. We have addressed all these concerns with our bespoke prefabricated heating systems.

These are essentially mini plant rooms systems with a bespoke configuration of either wall hung or floor standing boilers, pumps, and other components designed to address all site and project requirements. Fabricated off-site in quality-controlled conditions, the turnkey solution is then delivered on a wheeled frame, with insulated pipework set, ready for rapid connection.

Time & space savings

A Remeha bespoke rig was identified as the best time and space saving solution to boiler replacement at Bridgemary School.

Ridge and Partners LLP specified six Remeha Quinta 115 wall hung boilers on a bespoke rig to overcome space constraints and meet the tight installation schedule.

“Our experience of working with the Remeha team over the years has been consistently good, as they provide continued support from the initial selection through to commissioning,” said Ridge.

The boilers were arranged in a compact back-to-back layout on the wheeled rig unit. Pumps specifically selected for the duty required for plate heat exchanger operation, an expansion vessel, a pressurisation unit, and a dosing pot were integrated into the design.

To achieve hydraulic separation, a Plate Heat Exchanger (PHE) was selected to meet the specified boiler output and temperature, and oriented on the rig for non-disruptive future servicing. Air-dirt separation was installed to protect the PHE from the older retained secondary pipework. Controls were pre-wired to enable faster connection to the new Building Management System control panel.

M&E contractors IDWE said, “The bespoke rig solution was great – it was wheeled straight off the tail lift and into place, saving us a lot of valuable time.”

Minimising disruption

When Nottinghamshire Police refurbished the heating systems at a series of its stations, the critical challenge was the tight schedule as all sites needed to be fully completed within three months. Additionally, there could be no disruption to the hot water service throughout this period as all police stations were to be kept operational during the works.

Consultant CJR Midlands selected Remeha Gas 220 Ace floor standing boilers “due to Remeha’s excellent service and support, including assisting with surveys, and good availability of spare parts”. The ability to use prefabricated cascade arrangements floor-standing range was a major advantage on this extensive refurbishment project.

Working with CJR and M&E contractors ABSN, we prepared 3D drawings of the boiler cascade arrangement to the specified layout for each site and integrated LTHW and gas headers, pump sets and a PHE into the design. The project went smoothly with the challenging delivery dates successfully met.

ABSN said: “Early engagement with Remeha was central to the success of the scheme. Having the detailed co-ordinated dimensioned designs for each plantroom allowed us both to procure and to preinstall pipework in readiness for the boiler delivery. This helped speed up the installation process considerably.”
