Temporary Boiler Hire

Our fleet of temporary boilers boast impressive energy efficiencies and reliability. Combined with experienced, accredited and certified engineers, delivering a reliable, excellent service comes as standard with every hire we undertake.

We offer our clients a complete full turnkey hire solution, from surveying through to commissioning a temporary boiler. Our team of engineers and project managers will become an extension of your team and project. And because our packaged boilers come equipped with BMS, we’re able to have complete visibility and controllability of each boiler on hire. Fuel Management is also a service provided to clients that hire a packaged boiler from Rapid Energy.

Our team provides industry leading response times too. In an emergency, we can specify, deliver and commission a temporary boiler within 24 hours of receiving your call. Rapid Energy operates nationwide, 24/7.

Plate heat exchangers and calorifiers can be supplied for temporary hot water requirements. We can also supply and utilise FDA approved hoses.

Packaged boilers are available to hire on Gas, Gasoil and a sustainable fuel option called Hydrotreated Vegetable Oil (HVO). We also offer a range of temporary electric boilers which are trolley mounted, making them easy to manoeuvre and position (see full range below).

Boiler Capacity Range

Browse our range of boilers by capacity. We stock a wide range of boiler capacities to fulfil temporary heating and hot water requirements. Our smallest capacity packaged boiler plant starts at 150kW, rising to the largest packaged boiler within our fleet, the 2000kW (2MW).

Our smaller packaged boilers (150kW and 300kW) use a single phase 16a connection. Larger capacity packaged boilers utilise a three phase 32a connection.

We also stock an impressive capacity range of mobile electric boilers that can provide temporary heating for your project. Electric boiler capacities start with the single phase 15kW boiler, rising to the 40kW electric boiler which uses a three phase connection. Our electric boilers can be modularised to meet a higher capacity, if required.

Low Temperature Hot Water (LTHW) and Medium Temperature Hot Water (MTHW) packaged boilers are two distinct systems designed for different temperature requirements in heating applications. Here's a breakdown of their key differences:

  1. Temperature Range:
    • LTHW (Low Temperature Hot Water): LTHW boilers are designed to operate at lower temperatures typically ranging from 140°F (60°C) to 200°F (93°C). They are suitable for applications where moderate heat is required, such as space heating in residential buildings, schools, and offices.
    • MTHW (Medium Temperature Hot Water): MTHW boilers, on the other hand, are engineered to handle higher temperature ranges, usually between 200°F (93°C) and 250°F (121°C). These boilers are ideal for industrial processes, larger commercial spaces, and applications that demand higher temperatures.
  2. Applications:
    • LTHW: Common applications for LTHW boilers include space heating, radiant floor heating, and other scenarios where lower temperature hot water is sufficient.
    • MTHW: MTHW boilers are employed in industrial processes, such as manufacturing, chemical processing, and facilities with higher temperature requirements for specific applications.
  3. System Design:
    • LTHW: LTHW systems often feature components designed to handle lower temperatures, including pumps, valves, and heat exchangers optimized for the specified temperature range.
    • MTHW: MTHW systems are designed with components that can withstand higher temperatures and are engineered to efficiently transfer heat at elevated levels.
