ACV vs Elnur: Electric Boiler Comparison
Rather than burning fossil fuels, electric boilers generate central heating and domestic hot water using only electricity. Given that burning fossil fuels is bad for the environment and the supply isn't sustainable, electric heating systems look set to become a big part of the future of heating.
As many electric boilers aren't manufactured by the same recognisable names as natural gas and oil units, we've put 2 leading electric boilers head-to-head: ACV vs Elnur.

Is an electric boiler right for your home?
Electric boilers are best suited to smaller homes, as they can't meet the higher heating and hot water demands of larger properties. The best way to work out which output rating you need is by allowing 1.5 kW per radiator in your home. So, if you have 6 radiators then a 9 kW electric boiler should provide enough central heating to meet demand. However, a heating engineer will be the best person to consult when it comes to finding a new boiler for your home.

Compare ACV and Elnur
To find the right electric boiler for your home, it's important to compare electric boilers in a number of areas, including:
- Efficiency
- Warranty
- Potential Cost
And we've done these comparisons to save you from having to do them yourself.
Efficiency
If you're used to gas or oil boilers, then electric boiler efficiency might seem a bit confusing. The reason their efficiency appears so low is because they're hit by a fuel factor as electricity is considered a carbon intensive fuel.
ACV have boosted the efficiency of their E-Tech W boilers with the inclusion of heating elements made from INCOLOY 800 stainless steel and a high-efficiency charging pump.
Elnur boilers are able to achieve 100% efficiency thanks to the TRIAC technology and external chrono thermostat, which work together to weigh up heating capacity with the demands of the home. Doing this prevents the heating system from using more energy than is needed, helping to keep your energy usage and energy bills down to a minimum.
Warranty
When comparing boilers, whether electric, gas or oil, the warranty should always be an important part of your consideration.
ACV electric boilers come with a 1 year warranty as standard, that will see you're covered against any faults that have come about due to poor workmanship.
Elnur boilers come with a 5 year warranty which will see that you're protected against any faulty materials or defective parts as a result of the manufacturing process. Units with an internal hot water cylinder are also covered by a 5 year warranty.
Price
Other than the Elnur Mattira MAC combi boilers, which is the most expensive range in this comparison, there isn't too much between the potential cost of an ACV or Elnur electric boiler. And while you could be parting with a bit more money for an Elnur, their electric boilers can also be found at a lower price than an ACV too.
| Electric Boiler Range | Potential Cost (Before Installation) |
|---|---|
| ACV E-Tech | £1,128 – £1,820 |
| Elnur Mattira MAC | £2,100 – £2,370 |
| Elnur Mattira MAS | £1,025 – £1,200 |
Thanks to having a wider range of outputs to choose from and a lengthier warranty, if you find that you're having to pay more for an Elnur, it's probably worth the extra investment.
ACV vs Elnur: Which electric boiler manufacturer is the winner?
For anyone living in a small home or flat that's either not connected to the gas network or wants more flexibility with where to install the boiler, an electric boiler is a great option.
ACV and Elnur both offer a number of reliable electric boilers but thanks to their extensive range, 5 year warranty and focus on efficiency, we're crowning Elnur to victors of this boiler comparison.
