Electric Boilers

Electric heating - economical, 100% efficient and safe. All energy input is converted to heat, without any lost in waste gases.

Why Choose an Electric Boiler?

Electric boilers are an excellent alternative to a gas or oil boiler to run traditional radiator-based central heating or 'wet' underfloor systems. 

How do electric boilers work? 

Electric boillers are very simple and work in the same way as a kettle, heating water that passes over an element. They can come in a variety of different types and there are options that are identical in shape and size to a gas or oil boiler. With few moving parts they are exceptionally quiet and low-maintenance. 

Are electric boilers difficult to install? 

Because electric boilers heat the water directly without any flammable fuel, they don't produce any exhaust gases and therefore no flue is needed. This means they can be positioned almost anywhere so installation is very straightforward. The lack of any flames and potentially dangerous also means there are fewer building regulations to comply with which can save time as well as space. 

Will they work with existing radiators or underfloor systems?

With the majority of heating systems, all the existing pipework and hardware can be kept, all the way down to the controllers - though you may wish to upgrade to a new 'smart' controller - so it's often a case of taking your old boiler out and simply fitting a new one in its place.

Some homes may require a separate water heater installed. This can be in place of an existing immersion heater, but if there isn't already a cylinder in use, our advisers can find the best place to install one with minimal impact. For completely new systems, we can advise on both radiator-basedunderfloor or a combination of both to ensure you get the very best from your electric boiler. 

What are the benefits? 

Flow Boilers

Flow boilers, such as the EHC Fusion Comet boiler, provide an electric central heating option for your home. Electric flow boilers are allocated to the Super heat tariff and benefit from 18 hours of low rate unit cost and 6 hours of normal rate unit cost. Using your central heating programmer, it is advisable to set your heating times for the low rate times to help keep your heating bill to a minimum. It is then up to you as the customer to set the temperature on the central heating thermostat, as well as adjusting the temperature of each individual radiator by using the radiator TRV’s (thermostatic radiator valve).

Flow boilers can heat the property’s domestic hot water so long as you have an indirect hot water cylinder connected to the flow boiler. On this system, the flow boiler can circulate hot water through the hot water cylinder’s primary coil which in turn heats the water in the cylinder up to the desired temperature.

Combination Boilers

Combination water heaters, such as the Heatstor cylinder, provide your home with heating and hot water from the same vessel of water. The water is automatically heated for 18 hours every day on a low rate within the Superheat tariff. For the remaining 6 hours of the day on the normal rate, the heating elements are switched off automatically.

To make sure that you have sufficient hot water in the cylinder while the normal rate hours are in operation, it is advisable to run your central heating for at least 1 hour before the meter turns the cylinder off. This can be set up on the central heating programmer that was installed with your boiler. It is then the responsibility of the customer to set the temperature on the central heating thermostat, as well as amending the temperature of each individual radiator by amending the settings on the radiator TRV’s (thermostatic radiator valve).
