Existing heat pump support
When your ASHP needs more than a quick visual check
Heat-pump problems can come from hydraulics, flow, filters, controls, weather compensation, cylinders, pumps, valves or system settings as well as the heat pump itself. Our approach considers the complete wet heating and hot-water system.
Fault investigation
For fault codes, poor heating, loss of hot water, unusual noise or repeated problems, send us the make, model, postcode and symptoms so we can assess the appropriate next step.
Performance problems
We can investigate wider system factors such as circulation, emitter performance, control settings and hydraulic issues where these form part of the problem.
Proof, not stock claims
