Answer first
The strongest opportunities combine moderate delivery temperatures, long predictable run hours, usable heat sources or recovery, and a building that can accommodate emitters, plant and electrical demand. High-temperature processes or sharp peaks need separate analysis.
Start with interval energy data, existing plant, temperatures, occupancy, ventilation, hot-water demand and business-critical constraints. A domestic-style floor-area quote is not a commercial feasibility study.

Tell FLO about the building, present heat source, use pattern and project stage. The first conversation can identify the surveys, data and decision-makers needed for a credible proposal.
Characterise the loads
Separate space heating, ventilation, domestic hot water and process heat. Record temperatures, hours, seasonal variation and simultaneous peaks rather than one annual fuel total.
Half-hourly electricity, BMS trends, gas or oil data and temporary metering can reveal baseload, morning warm-up and avoidable control waste.
Find the best heat source and sink
Air source is widely applicable, while ground, water or waste-heat recovery may offer steadier source temperatures where the site permits. The sink may be radiators, air handling, underfloor, fan coils, hot water or process preheat.
Using a heat pump for a suitable low-temperature load while retaining a specialist high-temperature process can be better than forcing one system to do everything.
Check infrastructure and operations
Electrical capacity, plant-room space, external noise, planning, condensate, pipe routes, structural loading and maintenance access all influence feasibility.
Business continuity determines phasing, redundancy, temporary plant and controls. A building that cannot lose heat for an hour needs a different design and contract from an ordinary office.
Build an auditable business case
Compare net capital cost, grants or finance, energy scenarios, service, replacement, carbon and operational impacts. State measurement boundaries and do not count the same saving twice.
Define how post-install performance will be metered and reviewed. The project is not finished when equipment starts; it is finished when the building achieves the agreed outcome.

Questions people also ask
Can a heat pump supply high-temperature process heat?+
Some specialist systems can, but efficiency and equipment choice depend on source and delivery temperatures; assess each process separately.
Can existing commercial radiators stay?+
Possibly, after heat-loss, output, flow and control checks at the proposed temperatures.
Should the boiler always be removed?+
Not automatically. Redundancy, peaks, process needs and staged transition may justify retention, but annual heat share and exit strategy should be explicit.
