12kW vs 15kW:

12kW boiler is best suited to smaller, well-insulated homes with lower heating and hot-water demand. A 15kW boiler provides extra capacity for larger properties or homes with higher usage.

System vs Combi:

A combi boiler provides heating and hot water on demand from a single compact unit, making it ideal for smaller homes. A system boiler works with a separate hot water cylinder, making it better suited to larger properties.

Electricity Running Costs:

A typical 1–3 bedroom home using an ECA Arceus electric boiler can expect annual electricity costs of £800–£1,800, depending on insulation, usage and tariff rates. Running costs are slightly higher than gas, however require no flue, no gas safety checks and minimal servicing costs.

Fitted a few of these now. Have been impressed so far. First one I fitted was a few years back and not had a single issue. Customers are very happy with them also.

We just purchased a 12Kw electric Combi- Marco (MD) contacted me directly to offer some really helpful Tech support and professional expertise with the new installation of an electric combi boiler on one of our projects.

I had Gledhill Pulsacoil for water heating and storage. Since I changed it to an ECA system boiler, I don’t have any issues with hot water. Thanks Arda for the detailed information about the products. I recommend it to everyone!
