A useful first conversation
Plan the evidence before choosing the equipment.
Tell us about the building, current system, objective and timescale. We will explain the next sensible assessment without promising an outcome before the measurements exist.
For a new system
Design evidence comes before brand selection.
A survey should connect the proposed heat source to room or zone demand, emitters, hot water, controls, electrical capacity, equipment space and service access. The output is a comparable scope: what will change, what remains, which assumptions are provisional and how the finished system will be commissioned.
For renovations and new buildings, coordinate heating decisions with fabric, floor build-up, ventilation and electrical design before layouts are fixed.
For an existing system
Symptoms need operating context.
Record error codes, when the problem occurs, recent changes, pressure or temperature readings and any unusual sound, icing or cycling. Service history and commissioning records help distinguish a failed component from a hydraulic, control or design problem. Repeated resets can remove useful evidence, so capture the code before restarting equipment.
Maintenance, repair and redesign are different scopes; the first diagnosis should make the next one clear.
Maintenance, repair and redesign are different scopes; the first diagnosis should make the next one clear. That distinction prevents a routine service promise from being mistaken for a complete performance redesign.
Service questions
Choosing the right scope.
These questions help separate advice, design, installation, service and repair.
Do I need a heat-loss calculation before choosing equipment?
For a new heat-pump system, measured room or zone heat demand is a core design input. It informs equipment duty, emitters, water temperatures and the changes included in a comparable proposal.
Is a service visit the same as a system redesign?
No. Servicing checks condition and operation within an agreed scope. A redesign investigates whether demand, emitters, hydraulics, controls or equipment selection need to change.
Can you assess an existing renewable system?
Yes, subject to equipment and access. Share error history, commissioning records, settings and consumption data where available so the assessment can begin with evidence.
Do residential and commercial projects follow the same process?
Both need demand, distribution, controls and commissioning evidence. Commercial work usually adds operating hours, resilience, phasing, BMS or metering and more stakeholders.
What makes quotations comparable?
The same demand basis, intended temperatures, enabling work, controls, electrical scope, access, commissioning, handover and aftercare should be visible in each proposal.
