What Size Electric Central Heating Boiler Do I Need?
In the world of Electric Central Heating - there can be quite a myriad of confusing languages and guides that will only create confusion for the average user asking "What Size Electric Central Heating Boiler Do I Need?" We are on hand to aim to assist and clarify this in as easy and understandable terms as possible.
Sizing Calculations
The size of the electric central heating boiler you need depends on several factors, including the size of your property, the level of insulation, the number of occupants, and your hot water requirements. Here are some general guidelines to help you determine the size of the boiler you need:
- For Central Heating Setup: The average Central Heating system is fairly easy to calculate, the industry-standard estimation is to simply look at the number of radiators required, and multiply that number by 1.5 to give you the total KiloWatts necessary to power these radiators. Unusually long, old, or bespoke radiators may require a slight tuning, it's also a good idea to consider the insulation levels of your household as the above estimation may not be quite right given old-fashioned/bespoke radiator sizings in a poorly insulated property.
- For Under Floor Heating Setup: We can offer handy guides for Under Floor systems - check out this guide here which already discusses and explains the various calculations required to pinpoint your kW demand on an Underfloor system.
Suitable Styles
Once you have a rough idea of the KiloWatts necessary for usage across your heating system - it's best to then consider whether you're aiming to cater for your household hot water within the same unit or if you have a set-up where in which hot water can be created separately. The main issue people seem to face in their understanding is in that Central Heating, Underfloor Heating, and Hot Water for shower/drinking purposes all require a different temperature, and therefore circuit of water, to operate at.
Case 1) "I'd like one unit (boiler) to do my hot water as well as my central heating"
If this is the case, then the style of unit you would require is called a "combi-boiler". These are designed to, through gas or electric power, power both your washing/drinking waters and your central heating systems. We think Heatable summarise these styles of units very neatly in this article - Pictured below which is oriented towards Gas Powered Combi-Boilers
For those more Environmentally Conscious of you - we have a wonderful website section called "help me choose my" which should easily take you through the process of selecting an Electric Combi Boiler in a way that offers you a host of brand options suitable for your needs.
Case 2) "I'm happy to have separate systems/multiple units if necessary"
In this case here, we could largely recommend choosing a "Flow Boiler" as a means of Heating your home. One advantage of a system like this would be that the Flow Boiler can easily be adapted to use Central or Underfloor systems - and offer a neater and more compact solution for your Central Heating requirements. A Flow Boiler is a type of electric boiler that heats water as it flows through the unit. Unlike traditional electric boilers that store hot water in a tank, flow boilers heat water on demand, which can be more energy-efficient and cost-effective. Flow Boilers are also relatively compact and can be installed in smaller properties where space is limited. They are often used in combination with underfloor heating systems, as they can heat the water to a lower temperature, making them more efficient than traditional boilers. Our wonderful "help me choose my" section on the site also caters to this style of demand - allowing the user to in a few quick questions reach a host of suitable options for their needs.

Conclusion
In Conclusion - we hope to make the complicated world of Central and Household heating as simple, understandable, and easy as possible for the average person or specifier - Please note it's always best to consult a heating engineer to determine the size of the boiler you need. They can take into account your property's specific requirements and recommend a boiler that's the right size for your needs. In relation to Gas we would always recommend choosing a Please give us a call on 01934 253600 to receive further information, we are on hand to help from consideration to installation!
