In a special guest episode with Artisan Electrics, Heat Geek’s Adam Chapman answers the big homeowner question: are heat pumps worth it in 2025?
From cold weather performance to running costs, design myths to bad installs, this is a full breakdown for anyone on the fence about ditching their boiler.
Why This Video Matters
This was a proper sit-down with an electrician and a heating engineer, looking at how heat pumps work in real homes and what can go wrong when they’re not installed properly.
They covered:
- What a heat pump actually is (and how it works)
- Common install mistakes and how to spot them
- Do heat pumps work in old houses?
- Do you need solar or batteries?
- How to control heat pumps properly
- How to make sure your heat pump actually saves money
Key Takeaway: Good Design = Good Outcome
Adam breaks it down: bad installs make heat pumps look bad.
- The #1 thing that makes or breaks a heat pump install? A quality design.
- That means accurately calculating heat loss and matching the emitters (radiators) to the heat pump.
- Oversizing = wasted energy. Undersizing = cold home.
Heat Geek's LiDAR-powered survey app cuts this process from 3 days to 1 hour and feeds into their AI tool, ZeroDisrupt, to design installs that are fast, efficient, and lower cost.
What About Cold Weather?
Short answer: yes, they work.
- Heat pumps are widely used in Scandinavia and designed to run in temps as low as -15°C.
- If they fail in cold weather, it’s usually down to bad designnot the technology.
Adam also covers power cut concerns, noise myths, and installation flexibility.
You Don’t Need Solar...But It Helps
- You can run a heat pump without solar panels.
- Even on a standard or heat pump-specific electricity tariff, you can save money.
- Add solar or battery storage, and you amplify those savings—but they’re not required.
This flexibility means more homes can switch, even without roof space.
What Does a Good Install Look Like?
The team walks through multiple systems including a not-so-great install in a new build.
Telltale signs of a bodge job:
- No insulation on external pipes
- Metal-on-metal clips (lose heat fast)
- Condensate pipe not connected (leads to mould)
- Poor control setup (running at full power, short cycles)
Good installs are tidy, efficient, and well-insulated. You can spot them by the attention to detail.
So... Are Heat Pumps Worth It?
Yes, when they’re installed right.
That means:
- Accurate heat loss calculation
- Smart emitter selection
- Good control strategy
- And the right installer
With tools like Zero Disrupt, Heat Geek installs start at ~£3K (after grant), making them cost-comparable with boilers—but more efficient and future-proofed.
Final Word from Adam
"It’s not just about the hardware. It’s about the thinking. The best system in the world doesn’t work if it’s bodged in."
