Your questions answered
Boilers 4 Essex - Electric Boilers– FAQs
What is an electric boiler and how does it heat my home?
An electric boiler uses electrical elements to heat water for radiators/UFH and domestic hot water. There’s no flue or combustion, so it’s quiet and 100% efficient at the point of use.
Which type should I choose—combi, system or regular?
Combi: flats/smaller homes; instant DHW; no cylinder.
System: 2–4 bed homes; uses an unvented cylinder for stored hot water.
Regular: suits older systems with tanks.
Cylinder with immersions: great for high DHW demand.
Are electric boilers expensive to run?
Electricity is pricier per kWh than gas, but installs are simpler (no flue), servicing is minimal, and pairing with solar PV/off-peak tariffs can significantly cut running costs.
What sizes (kW) do electric boilers come in?
Typical UK ranges are ~4–15 kW for most homes, with some models higher for larger loads. Your heat-loss survey determines the exact size.
Do electric boilers work with existing radiators and underfloor heating?
Yes—modern units (e.g., Amptec, Elnur, EHC) are compatible with standard radiators and UFH when correctly specified.
Can I get hot water from an electric boiler?
Yes. Choose an electric combi for instant DHW, or a system/regular boiler with an unvented cylinder for higher DHW volumes.
What are the best electric boilers right now?
Heatrae Sadia Amptec, Elnur Mattira, EHC Fusion Astro, Ferroli LEB and more—picked for reliability, efficiency, support and warranty.
How long does installation take?

Is there any grant support?
Hybrid heat pump setups (e.g., Vaillant AroTHERM with electric backup) can be eligible via the Boiler Upgrade Scheme; we advise on options during survey.
What maintenance is required?
Very little compared to gas—no combustion, fewer moving parts. Periodic safety/pressure checks and cylinder servicing (where fitted) are recommended.
Are electric boilers noisy?
They’re noted for quiet operation—no burner or fan.
