FAQs about industrial water boiler hire
Hot water boiler hire periods are highly flexible and can be tailored to your operational needs. Many customers hire a boiler for short-term use, such as emergency heating, planned maintenance or seasonal demand, which can range from a few days to several weeks. For longer projects, industrial sites, district heating networks and commercial buildings often rent boilers for several months or multiple years.
We can scale packages up or down as your site needs change, and we offer complete flexibility to extend, shorten or modify the rental period at any time.
The right boiler size depends on your heat demand, flow temperature, system design and the type of application you’re supporting. As a guide, you’ll need to consider:
- Heat load (kW/MW: the amount of energy required to maintain process or space temperatures.
- Flow and return temperatures: higher temperature lifts require more capacity.
- System volume and distribution losses: long pipe runs, poor insulation or large heating networks may require additional output.
- Application type: process heating, district heating, building heat and hot-water production all have different demand profiles.
Rather than estimating, we recommend a site survey or technical consultation. Our specialists will assess your heating demand, network characteristics and operational goals to specify the most efficient solution – whether that’s a 250kW unit, a 2.5MW boiler or a multi-MW modular package.
Our industrial hot water boilers can operate on diesel, gas or sustainable fuels such as HVO. This fuel flexibility allows us to match your operational requirements while helping you meet environmental and compliance targets.
- Diesel is a reliable and widely available option, suitable for most temporary and emergency heating applications.
- Gas offers low NOx emissions and can support sites with existing gas infrastructure.
- HVO is a renewable, low-carbon alternative that can reduce greenhouse gas emissions compared to conventional diesel, helping organisations align with sustainability strategies and environmental regulations.
Whichever fuel you choose, our engineers optimise burner configuration, combustion control and system efficiency to achieve stable performance and minimise emissions. All equipment is maintained to ensure safe, compliant operation throughout the hire period.
All our hot water boiler rental packages come with comprehensive maintenance and continuous performance oversight to keep your system operating safely and efficiently throughout the hire period.
- 24/7 technical support – our engineers are available around the clock to respond to any issues or performance concerns.
- Proactive maintenance – routine servicing, inspections and compliance checks are included as standard, reducing the risk of unplanned downtime.
- Aggreko Remote Monitoring – every boiler is connected to our remote monitoring platform, giving us real-time visibility of performance, fuel use, temperatures and system alarms. This allows our specialist to identify faults early and take corrective action before they affect your operations.
- On-site engineering support – if needed, our team can be deployed quickly for troubleshooting, optimisation or component replacement.
Together, these services ensure your temporary hot water system run reliably, safely and at peak efficiency for the entire duration of the hire.
Our hot water boiler hire service is designed to support urgent, unplanned and emergency situations. With a nationwide fleet and 24/7 technical support, we can mobilise equipment and engineers at short notice to restore heating and hot water quickly. Our priority is keeping your operations safe, compliant and running – even in the most challenging conditions.
At the end of the hire period, we manage the entire off-hire process to ensure a smooth and disruption-free transition. Once you confirm that the boiler is no longer required, our team will carry out a controlled shutdown, disconnect all temporary connections, arrange collection and removal of the boiler and any supporting equipment, and restore the site to its original condition.
