Heat Geek ZeroDisrupt: What It Does and What It Does Not

How does Heat Geek ZeroDisrupt work?

The process starts with a proper design consultation, not a photograph of the old boiler and a hopeful guess at the new heat pump size. Heat Geek says its consultation normally includes a full room-by-room heat loss, checks of the radiators, pipework and electrical supply, outdoor positioning and a noise assessment.

We use the iPad LiDAR scanner to capture room geometry and build a digital model. The survey also records the construction, windows, doors, radiators, pipework, cylinder and the practical route for new equipment. A beautifully scanned room with the wrong wall construction is still the wrong calculation, so the surveyor has to verify the inputs.

ZeroDisrupt then uses those property details with Heat Geek's real-world installation and monitoring data to compare system configurations. The result is a proposal showing the heat pump, heat loss, cylinder and location options, likely radiator changes, running-cost estimate and other work identified during the visit.

Does ZeroDisrupt mean you can keep every radiator?

No. It means each radiator has to earn its replacement.

An existing radiator may stay if its output is enough for that room at the selected design temperature. Another may need upgrading because it cannot meet the room heat loss without pushing the whole system hotter. Heat Geek's homeowner guidance puts the choice plainly: retaining more radiators can reduce the installation price, while changing more may support greater annual savings.

The same principle applies to pipework and hot-water equipment. Some existing parts can be retained when the calculations and condition support it. Others need changing because of flow, capacity, condition, compatibility or access. “Keep what works” is sensible; “keep everything whatever the maths says” is not.

The real trade-off: upfront work versus designed efficiency

Lower heat-pump flow temperatures mean better efficiency. That direction is not in doubt. The design question is how much emitter area and system work the home needs to stay warm at the chosen temperature.

ZeroDisrupt makes that choice easier to see. One option may keep more existing radiators and cost less to install. Another may replace more radiators, run cooler and reduce estimated annual electricity use. The point is that the customer can compare heat pump installation costs and proposed changes instead of receiving one long list of upgrades with no explanation of what each one achieves.

Heat Geek currently says a typical ZeroDisrupt installation costs around £3,000 after available grants, but also says price varies with property size, heat loss and specification. That is a national Heat Geek guide, not a promise that every Vector Heat quotation will be £3,000. The current Boiler Upgrade Scheme guide explains which grant may apply before any after-grant figure is compared.

What the software cannot know on its own

Software can compare the information it is given. It cannot see every concealed tee, crushed pipe, historic blockage or inventive bit of plumbing below a floorboard. It cannot judge access, workmanship or the condition of a component unless somebody records that evidence accurately.

This is why ZeroDisrupt does not replace an experienced heating engineer. The designer still has to check:

• whether the room measurements and construction assumptions are right
• whether the existing radiators, pipework and cylinder match the recorded data
• whether the proposed flow rates are practical through the real system
• whether the outdoor unit, electrical work and hot-water equipment can be installed properly
• whether renovation plans or future fabric improvements change the design

Heat Geek also says its AI does not replace engineers. That matters more than the letters “AI” on the quotation.

Why Vector Heat uses ZeroDisrupt

I have worked in plumbing and heating for 23 years, spent 14 years surveying more than 5,000 properties and have six years of heat-pump design and installation experience. The best use of software is to make that survey work clearer and more consistent, not to pretend the property has stopped being physical.

We use ZeroDisrupt because it helps us show what each proposed change is doing. That fits our approach: design first, install second, and do not replace useful equipment just because it is easier to put every possible item on the quotation.

If you want Vector Heat to handle that route in Lincolnshire, our Heat Geek consultation follows the same survey-led process. For the wider design and installation service, see heat pump installation in Lincolnshire.
