Heat Pump Guide
Is the Dimplex Edel Worth It?
With energy prices remaining high and more UK homes moving away from gas, air source heat pump hot water cylinders like the Dimplex Edel have become increasingly popular. But is the Edel actually worth the investment?
In this guide, we'll take a detailed look at the Dimplex Edel range (170L, 200L, and 270L models), how it works, real running costs, pros and cons and how it compares to traditional hot water systems.
How the Dimplex Edel works
The Dimplex Edel is an integrated air source heat pump hot water cylinder. Unlike traditional systems that generate heat directly, the Edel extracts free heat from the outside air through ducting and upgrades it using a compressor mounted on top of the cylinder.
This process delivers over 300% efficiency (COP up to 3.43). It also includes a backup immersion heater for high-demand periods and smart app control via the Dimplex Hub for scheduling and solar PV optimisation.
Key advantages of the Dimplex Edel
- Exceptional energy efficiency — up to 70-75% lower electricity use than immersion heaters
- Significantly lower running costs
- Reduced carbon emissions and better EPC ratings
- Quiet operation (as low as 36 dB(A))
- Compact design suitable for cupboards and utility rooms
- Eligible for the Boiler Upgrade Scheme grant (£7,500 in many cases)
Dimplex Edel vs traditional hot water cylinders & immersion heaters
Here's how the Edel compares to common alternatives:
| System | Efficiency | Running Cost | Upfront Cost | Best For |
|---|---|---|---|---|
| Dimplex Edel | 300%+ (COP 3.43) | Low | Higher | Off-gas homes |
| Standard Immersion Heater | 100% | High | Low | Small households |
| Gas Boiler + Cylinder | ~90% | Medium | Medium | Gas-connected homes |
Dimplex Edel model comparison
Not sure which size you need? Here's a quick breakdown:
| Feature | 170L Model | 200L Model | 270L Model |
|---|---|---|---|
| Best For | 1-3 bedrooms | Most 3-4 bedroom homes | Larger families |
| Capacity | 170 litres | 200 litres | 270 litres |
| Diameter | 520mm | 630mm | 630mm |
| COP | Up to 3.43 | Up to 3.43 | Up to 3.43 |
| Noise Level | 36 dB(A) | 36 dB(A) | 37 dB(A) |
Running costs in 2026
With a COP of 3.43, the Edel typically uses around one-third of the electricity of a standard immersion heater. Many households report substantial savings, especially when combined with solar panels or off-peak tariffs.
Installation & grants
The Edel is designed for straightforward installation by a qualified plumber. In 2026, many properties still qualify for the Boiler Upgrade Scheme, which can provide up to £7,500 towards installation.
Is the Dimplex Edel worth it?
"For most off-gas homes, yes — especially if you can access the grant and pair it with solar PV. The combination of high efficiency, smart features and long-term savings makes it one of the best hot water solutions currently available."
