Moving away from gas, oil or LPG can feel like a big decision. There are more electric heating options available than ever, but what works well in one home may not be right for another.
Before choosing a new heating system, it helps to understand how your home is heated today, how much heat it needs and what changes may be required.
Here are six things worth checking before you make the switch.
1. Start with the heating system you already have
If your home already uses standard radiators or wet underfloor heating, that can make the switch to electric heating more straightforward.
Many people assume going electric means replacing every pipe and radiator in the house. In many cases, a wet central heating replacement such as the tepeo ZEB heat battery boiler can work with existing radiators and heating controls, helping to reduce disruption.
The important thing is whether your existing radiators and pipework are suitable for the heat your home needs. A professional assessment should confirm that, and identify whether any changes are required.
2. Understand how much heat your home actually needs
Two homes that look similar from the outside can have very different heating requirements.
Things like property size, age, insulation, glazing and how exposed the building is all affect how quickly it loses heat.
This matters because the right heating system needs to keep your home comfortable including on colder days.
A well-insulated home will generally need less energy to stay warm, but that does not mean every property needs a major insulation retrofit before switching to electric heating. What matters is understanding your home’s heat demand and choosing a system that is suitable for it.
3. Think about hot water as well as heating
This is especially important if you currently have a combi boiler.
A combi boiler provides both central heating and hot water from a single unit, so changing heating systems may mean reviewing how your hot water will be supplied.
A tepeo ZEB works differently, so homes moving from a combi boiler will usually need to include a hot water solution as part of the overall system.
Depending on the property, that might be a traditional cylinder, a smart cylinder or a compact heat-storage solution.
It is worth understanding this early, because the space available for hot water can influence the overall installation.
4. Check whether your electrical setup is ready
An electric heating system naturally places more demand on your home’s electrical supply than a fossil-fuel boiler.
That does not automatically mean you will need major electrical work, but it does mean the supply and existing setup should be properly assessed.
An installer should look at the electrical capacity of the property alongside other significant loads in the home, such as EV charging, electric hot water or a home battery.
If upgrades are needed, these should be identified before installation so they can be factored into the plan and quote.
5. Look beyond the headline electricity price
One of the biggest differences between electric heating technologies is not simply how much electricity they use, but when they need to use it.
A direct electric boiler draws electricity at the moment when your home needs heat. A heat battery boiler such as the ZEB can charge ahead of time, storing energy as heat and releasing it later.
That means a suitable time-of-use tariff can make a significant difference to running costs, because more charging can take place during lower-cost periods.
So when comparing options, do not just look at the standard electricity unit rate. Think about:
- Off-peak rates
- How many cheaper hours are available
- The peak rate
- Whether the tariff suits the rest of your home
- Whether you have an EV, solar panels or home battery

6. Make sure the system fits your actual property
Finally, there is the practical question: where will everything go?
For a ZEB, that means suitable indoor space for the unit, access for installation and enough room around the system for the necessary connections.
The good news is that there is no outdoor unit, which can make it easier for homes with limited external space.
But every property is different, so suitability is about more than one measurement or feature. The overall picture includes:
- Heat demand
- Wet central heating
- Indoor space
- Hot-water setup
- Electrical capacity
- Electricity tariff

So, is your home ready for electric heating?
The answer is not always obvious from one factor alone.
A home might have older radiators but relatively low heat demand. Another might be very well insulated but have limited indoor space. That is why proper suitability assessment matters.
At tepeo, our Home Check looks at key property and heating information to give you an initial indication of whether a ZEB could work in your home.
Complete the 30-second Home Check
Before switching to electric heating, check:
- Do you have radiators or underfloor heating?
- Do you know your approximate heat demand?
- Have you considered your hot-water setup?
- Is your electrical supply suitable?
- Can you access a time-of-use tariff?
- Is there suitable space for the new system?
