Where more than a single hired boiler is needed to keep a building warm during a full plant replacement, extended works or an unplanned failure, ComGas can assess your site and co-ordinate a broader interim heating strategy alongside the main project. Scope and availability depend on survey and the arrangements confirmed at the time.
A single temporary boiler is often enough to bridge a short gap. But where a building is undergoing a full plant replacement, a longer refurbishment, or has lost heating across multiple zones or buildings, the interim arrangement needs to be considered as a project of its own — covering distribution around the site, connection points, and how the temporary provision will be phased alongside the main works.
ComGas can assess a site facing this kind of situation, discuss what interim heating strategy may be achievable, and co-ordinate the temporary arrangement alongside a planned boiler or plant replacement project. As with a single temporary boiler, we do not operate our own hire fleet and do not guarantee stock, a fixed delivery timescale or continuity of supply — what is achievable depends on a site assessment and the arrangements confirmed at the time.

Temporary heating co-ordination from Farnham, Surrey.
For larger or longer situations than a single hired boiler can cover, we can help plan and co-ordinate the interim arrangement alongside your main project.
Assessing the scale of heating loss across the building or site, and how it relates to the timescale of the main boiler or plant project.
Discussing an appropriate interim heating strategy and co-ordinating it alongside the main installation or replacement project.
Installing and connecting the agreed interim heating provision, carried out by Gas Safe registered engineers.
Removing the interim arrangement and handing back to permanent heating once the main project is complete.
Planned. Professional. Practical.
Before proposing anything, we look at how much of the building or site is affected, how long the main project is expected to take, what distribution and connection points exist, and where interim provision could realistically be sited without disrupting the main works. Where the main project is being delivered in phases, the interim heating strategy is considered alongside that phasing rather than as a single fixed arrangement.
This assessment shapes what is proposed and how it is phased. As with any interim arrangement, we explain honestly what is achievable for the specific project rather than assuming a standard solution will fit every situation.
As with a single temporary boiler, ComGas does not own a hire fleet and does not have an exclusive arrangement with a single hire provider. What interim heating provision can be arranged for a larger project, and how it is phased, depends on a site assessment and on the arrangements that can be confirmed once the requirement is understood. We set this out clearly so it can be planned around realistically, alongside the main project timescale.
Scope, specification and availability for a temporary heating solution are confirmed following a site assessment and depend on what can be arranged at the time. No delivery timescale, stock level or continuity of supply is guaranteed in advance of that assessment.

A 500 kW temporary boiler installation in the adjacent car park kept heating running while the theatre’s permanent plant was isolated, removed and replaced.

Common questions about how ComGas assesses and co-ordinates broader interim heating provision.
Talk to the team about interim heatingA single temporary boiler, covered on our Temporary Boiler Hire page, suits a straightforward gap in provision. This page covers a broader interim heating strategy — needed where more of the building or site is affected, or where the interim arrangement needs to be phased alongside a longer plant replacement project.
We can assess the scale of heating loss across a site and discuss what interim strategy may be achievable, including how any provision would be distributed. What can actually be arranged depends on the site assessment and the connections and access available.
No. As with a single temporary boiler, we do not promise a fixed delivery or continuity guarantee in advance. What is achievable, and how it can be phased, is confirmed once we have assessed your site and the wider project timescale.
Yes. Where a main boiler or plant replacement project is being delivered in stages, the interim heating strategy is planned alongside that phasing, rather than treated as a single fixed arrangement for the whole project duration.
The interim arrangement is removed and normal operation is handed back to the permanent installation, co-ordinated with the team delivering the main boiler or plant replacement project.
Tell us about the building, the scale of the heating requirement and the timescale for the main project. We can arrange a site assessment and discuss what interim strategy may be achievable.
