Why Choose a Daxom Electric Combi Boiler?

Electric combi boilers provide central heating and domestic hot water using electricity rather than burning gas or oil at the property. For homes without mains gas, compact properties or installations where a flue is impractical, a Daxom electric combi boiler may be worth considering. The right choice depends on your property’s heat loss, available electricity supply, hot-water demand and running-cost expectations.

Benefits of Daxom electric combi boilers

1. No gas supply, flue or on-site combustion

An electric boiler heats water without burning gas or oil, so the boiler itself does not produce combustion exhaust gases or require a combustion flue. That can simplify planning in suitable locations. All electrical and plumbing work must still meet the applicable installation requirements, and other fuel-burning appliances in the property may still need appropriate carbon monoxide precautions.

2. Compact heating and hot water in one appliance

A Daxom compact combi boiler can supply both radiators or compatible wet underfloor heating and domestic hot water without a separate hot-water cylinder. Our 12kW Compact Electric Combi Boiler measures 700 × 400 × 220 mm (height × width × depth). The chosen installation position must provide safe access, clearance and an adequate electrical supply.

3. Straightforward temperature controls

Selected Daxom models include a digital control panel, adjustable central-heating and hot-water settings and compatibility with suitable external room thermostats. Smart or app-based control depends on the specific controls installed; it is not automatically included with every boiler.

4. Quiet operation and fewer combustion-related components

There is no gas burner, combustion fan or conventional flue system inside a direct electric boiler. Operation can be quiet, although circulation pumps and normal water-flow noise may still be audible. This also removes some gas-boiler-specific service components, but does not mean the boiler is maintenance-free.

5. Suitable for particular off-gas and space-restricted homes

Electric combi boilers can be an option for smaller or well-insulated properties, flats and certain buildings where a gas connection is unavailable or undesirable. Suitability is not universal: hot-water flow rate, electrical capacity and the building’s heating demand must be calculated and checked before purchase.

Are electric combi boilers efficient?

Direct electric resistance heating converts nearly all electricity used at the point of use into heat, but high conversion efficiency is not the same as low running costs. Electricity typically costs more per kWh than mains gas, and heat pumps can deliver more heat per unit of electricity than a direct electric boiler. Compare the available alternatives for your own home rather than relying on a general efficiency percentage.

How much does an electric combi boiler cost to run?

Daxom cannot guarantee a particular household’s electricity consumption or heating bill. Running costs depend on your property’s size, construction and insulation, its heat loss, weather, thermostat settings, heating schedules, household hot-water use, electricity tariff and occupier habits. A suitably designed and controlled heating system can help avoid unnecessary consumption, but it does not eliminate the electricity required to heat the property.

What should you check before buying?

  • Heat-loss calculation: ask a competent installer to establish the property’s heating demand; the boiler must be correctly sized.
  • Electrical capacity: verify the available supply, circuit design, protective devices and any network requirements with a qualified electrician.
  • Hot-water demand: compare expected flow rates against the number of bathrooms and simultaneous use.
  • System compatibility: check radiators or underfloor heating, controls, circulation and manufacturer water-treatment requirements.
  • Installation and servicing: read the product manual and check access, maintenance requirements and warranty conditions.
  • Total costs: compare purchase, installation and likely electricity costs with appropriate alternatives, including heat pumps where practical.

Installation, annual servicing and warranty

Daxom electric combi boilers must be installed and commissioned according to the relevant instructions and regulations. Proper servicing and maintenance remain important. Daxom’s optional five-year extended warranty is subject to eligibility, a satisfactory installation confirmed by Daxom at the first-year service, and continued annual Daxom servicing. The optional extension is available only for qualifying installations in England and Wales. Read the complete Daxom Terms, Returns and Manufacturer Warranty for the precise conditions and statutory-rights information.
