The way we heat and power our homes is changing.

For decades, many homes have relied on gas, oil or LPG for heating, while electricity has been used separately for lighting, appliances and everyday household needs.

An all electric home takes a different approach.

Instead of treating heating and electricity as completely separate systems, technologies such as heat pumps, solar PV and battery storage can be designed to work together.

A heat pump uses electricity to provide heating and hot water.

Solar PV generates electricity at your property.

Battery storage allows some of that electricity to be kept for use later.

Individually, each technology has a role.

When they are considered together, they can create a more joined up home energy system that gives homeowners greater control over how electricity is generated, stored and used.

That does not mean every home needs all three technologies.

It does not mean you have to install everything at once either.

The starting point is understanding your property, how you currently use energy and what you want your home energy system to achieve.

An all electric home is a property designed to use electricity for its main energy needs rather than relying on fossil fuels such as gas or oil for heating.
For many existing homes, one of the biggest changes is replacing the traditional boiler with a heat pump.
The home may then combine several technologies, including:
Air source or ground source heat pumps
Solar PV
Battery storage
Underfloor heating
Smart heating controls
Smart electricity tariffs
Electric vehicle charging where relevant
The exact combination depends on the property and the household.
Some homes may begin with a heat pump.
Others might already have solar panels and later add battery storage.
A homeowner planning a major renovation might decide to consider all of these systems together from the beginning.
There is no single template.
The important part is designing the system around the home rather than simply collecting individual technologies.

Think about the way a traditional home often uses energy.

Gas may provide heating and hot water.

Electricity powers appliances.

Solar panels, if installed, generate electricity independently.

Each system can effectively operate as its own separate part of the home.

An integrated electric home creates more opportunities for those systems to interact.

Solar panels can generate electricity during daylight hours.

That electricity can be used immediately by the home.

If more electricity is generated than the home currently needs, some of the surplus can potentially be stored in a battery.

The battery can then make that electricity available later when the solar panels are producing less.

The heat pump is another electrical demand within that wider system.

This is where planning becomes valuable.

Instead of asking:

Which heat pump should I buy?

Which solar panels should I buy?

Which battery should I buy?

A more useful question can be:

How should my home generate, store and use energy as a complete system?

The heat pump is at the centre of the heating side of an all electric home.

Instead of burning gas, oil or LPG to create heat, a heat pump transfers naturally occurring heat from the surrounding environment into the property.

An air source heat pump collects heat from the outside air.

A ground source heat pump collects heat from the ground.

Electricity powers the process.

Because the heat pump is transferring existing heat rather than producing all of the heat directly from electricity, it can provide several units of useful heat for each unit of electricity consumed.

But the heat pump itself is only part of the heating system.

For it to work effectively, the property needs to be assessed properly.

That includes understanding:

• Heat loss
• Radiator requirements
• Pipework
• Hot water demand
• Heating controls
• Required room temperatures
• Outdoor conditions

This is why Renewable Heat starts with the home before selecting the equipment.

Solar PV panels convert daylight into electricity that your home can use.

One common misconception is that solar panels need strong sunshine to work.

They do not.

Solar PV generates electricity from daylight, which means panels can continue generating on cloudy days, although output naturally changes with conditions, season and available daylight.

That makes solar PV relevant to Scottish homes too.

The electricity generated can be used by appliances and other electrical systems while it is available.

If your home is using electricity at the same time your solar panels are generating it, that can reduce the amount of electricity you need to import from the grid at that moment.

The Energy Saving Trust confirms that solar panels can generate electricity on cloudy days and describes solar as an established option for homes across the UK.

But solar generation and household electricity demand do not always happen at the same time.

That is where battery storage becomes interesting.

Solar panels may produce electricity during the middle of the day when household demand is relatively low.

The home may then need more electricity later in the evening when solar generation has fallen.

Battery storage can help bridge part of that gap.

A home battery can store electricity and make it available later.

That electricity might have come from solar PV.

Depending on the system and electricity tariff, the battery may also be charged from the grid during periods when electricity is cheaper and used when electricity prices are higher.

Energy Saving Trust guidance confirms that battery storage can work both with solar PV and with smart time of use electricity tariffs.

It also specifically identifies running a heat pump as one potential use for stored electricity.

This creates more flexibility.

But it is important to be realistic.

A battery does not make a home completely independent from the electricity grid.

Its usefulness depends on factors including:

• Battery capacity
• Household electricity consumption
• Solar generation
• Heat pump electricity demand
• Electricity tariff
• Time of day
• Season

The correct battery therefore needs to be selected around the household rather than simply choosing the largest capacity available.

This is where the idea of an integrated electric home becomes easier to understand.

Imagine a typical day.

During daylight hours, the solar panels generate electricity.

Some of that electricity is used immediately by the home.

That could include appliances, lighting and whatever portion of heat pump electricity demand happens at the same time.

If the solar panels generate more electricity than the home currently needs, surplus electricity may be available for the battery.

Later in the day, solar generation falls.

The battery may then provide some stored electricity to the property.

When stored electricity is unavailable or insufficient, the home continues to draw electricity from the grid.

The grid remains an important part of the system.

The Energy Saving Trust makes this distinction clear. Solar panels cannot be expected to directly power a heat pump at all times because heating demand is often highest during winter and outside daylight generation periods.

Battery storage can move some electricity from one part of the day to another.

It cannot store summer solar generation for use throughout the winter.

Not all of the time.

This is worth explaining clearly because it is easy for homeowners to misunderstand the relationship between solar panels and a heat pump.

Heat pumps generally require the most energy during colder months.

Solar generation is generally greatest during the brighter months of the year.

There is also the daily timing issue.

A heat pump may need electricity at night or early in the morning when solar panels are not generating.

Solar PV can therefore contribute towards the electricity used by the heat pump, but the home will still rely on the grid at other times.

Battery storage can improve the amount of solar electricity that remains available for use later in the day, but the battery itself has a finite capacity.

The aim should not be to promise that the heat pump will run entirely from solar.

The more useful goal is to understand how much electricity the home is likely to generate, store and consume throughout the year.

Once heating becomes electric, the way you buy electricity becomes more important.

Traditional electricity tariffs may charge the same unit rate throughout most or all of the day.

Smart time of use tariffs can offer different prices at different times.

This can create opportunities for homes with batteries and heat pumps.

For example, a battery may potentially charge when electricity prices are lower and provide some stored electricity when grid prices increase.

The best strategy depends on the household and tariff.

It also changes over time as electricity tariffs and products change.

That is why any financial estimate should be based on realistic household usage rather than assuming a particular tariff will always be available.

The Energy Saving Trust has specifically researched how heat pumps, batteries and electricity tariffs can work together and highlights tariff choice as an important part of the overall energy picture.

Buying three high quality products does not automatically create a well designed home energy system.

The technologies need to be selected around the property.

That starts with understanding energy demand.

How much heating does the home require?

How much hot water does the household use?

How much electricity is currently consumed?

How much roof space is available for solar PV?

When does the household use most of its electricity?

Would battery storage be useful?

Is an electric vehicle likely to be added later?

Are renovations planned?

These questions affect system design.

At Renewable Heat, our Home Assessment looks at the property and current energy use before the system is designed.

Our current approach includes creating a model of the home to help forecast heating and energy demand.

That allows the heat pump, solar PV and battery to be considered as connected parts of the same project rather than separate purchases.

Renewable Heat has more than 20 years of experience designing and installing home heating and energy systems.

Our approach begins with understanding the property.

The aim is to establish:

• How much heat the home requires
• How much energy the household currently uses
• Which existing heating components are suitable
• What needs upgrading
• What solar generation may be possible
• Whether battery storage is appropriate
• How future plans might affect demand

From there, the technologies can be designed around the home.

That might result in a heat pump installation alone.

It could be a heat pump and solar PV.

It might include battery storage too.

Some properties may also benefit from underfloor heating in appropriate areas.

The point is not to install the maximum number of products.

It is to choose the technologies that make sense for the property.

Underfloor heating can work particularly well with heat pumps.

Instead of concentrating heat into individual radiators, underfloor heating distributes warmth across a large floor area.

This can allow comfortable room heating at relatively low water temperatures.

Lower heating water temperatures can provide good operating conditions for a heat pump when the system is correctly designed.

Underfloor heating can be particularly attractive in:

• Newly built homes
• Extensions
• Major renovations
• Open plan living areas

But it is not required for an all electric home.

A properly designed radiator system can also work effectively with a heat pump.

Again, the answer depends on the property.

No.

This is one of the most important points for homeowners.

Creating an all electric home does not have to mean completing one enormous project.

You can take a staged approach.

For example, the first priority might be replacing an ageing fossil fuel heating system.

Solar PV could be added at the same time or later.

Battery storage might make sense once you better understand your new electricity consumption.

Alternatively, you may already have solar PV and be considering a heat pump and battery.

There is no single correct order for every home.

The important thing is having a wider plan so that decisions made today do not unnecessarily restrict your options later.

You do not need to start again.

If your property already has solar PV, that system can be considered as part of the wider home energy plan.

The important questions become:

• How large is the existing solar system?
• How much electricity does it generate?
• How much of that electricity does the home currently use?
• How much is exported?
• Is battery storage already installed?
• How might electricity demand change after installing a heat pump?

Adding a heat pump changes the property’s electricity profile because heating and hot water now create additional electrical demand.

That does not automatically mean the existing solar system is too small.

It simply means the system needs to be understood as part of the overall energy picture.

The same principle applies.

A heat pump can be installed without solar PV or battery storage.

You can then explore additional technologies later.

If you are considering solar PV, the installer can look at available roof space and household electricity consumption.

If battery storage is being considered, the system can be sized around the way electricity is generated and used.

The Energy Saving Trust advises homeowners with heat pumps to consider additional low carbon technologies and provides specific guidance on solar panels and battery storage.

This makes an existing heat pump a natural starting point for a wider home energy conversation.

No.

An all electric home still uses energy.

You will normally continue to use electricity from the grid.

Solar PV can reduce the amount of grid electricity you need to purchase when generation and consumption align.

A battery can allow some electricity to be stored for later.

A heat pump can use electricity efficiently to provide heating.

But none of these technologies makes energy demand disappear.

The goal is better management of household energy rather than pretending the home no longer needs the grid.

This is why we would avoid claims that every all electric home is completely self sufficient.

Real world performance depends on the property, system design, household use, weather and electricity tariff.

Not necessarily.

This is another area where careful wording matters.

Replacing fossil fuel heating with an electric heat pump can reduce direct fossil fuel use within the home.

Solar PV can generate renewable electricity on site.

Battery storage can help the household make greater use of available solar generation or lower price electricity.

But the carbon impact of electricity imported from the grid varies depending on how that electricity is generated.

For that reason, lower carbon home energy system is generally a more accurate description than assuming every all electric home is automatically zero carbon.

The objective is still significant.

It is about moving away from burning fossil fuels in the home and creating a system that can increasingly take advantage of renewable electricity.

Solar panels do not require hot weather.

They require daylight.

The Energy Saving Trust confirms that solar panels continue generating electricity on cloudy days.

Its 2026 analysis of domestic solar installations also shows widespread solar adoption across Scotland, with many Scottish local authorities recording above average numbers of domestic solar installations relative to population.

Heat pumps are also designed to operate in cold conditions when the system is correctly selected and designed.

The challenge is therefore not whether Scotland is sunny or warm enough for these technologies to exist.

The real questions are about the individual property.

Does the roof suit solar PV?

How much heat does the home require?

What outdoor conditions should the heat pump be designed around?

What electricity demand will the household have?

What battery capacity, if any, would be useful?

Those are property specific questions.

Potentially.

As homes become more electrified, transport may become another significant electrical demand.

If you already own an electric vehicle or expect to purchase one, it can be useful to mention this during the home energy design process.

Future EV charging affects electricity consumption.

That can influence decisions about:

• Solar PV size
• Battery capacity
• Electrical supply
• Charging strategy
• Smart tariffs

You do not need to predict every future purchase.

But considering obvious future changes can help avoid designing a system around today’s electricity use alone.

The benefits will differ between households, but a well designed system can potentially provide:

Less reliance on fossil fuel heating

A heat pump can replace gas, oil or LPG as the main heating source where appropriate.

More electricity generated at home

Solar PV can provide electricity during daylight hours.

Greater use of your own solar electricity

Battery storage can retain some surplus generation for later use.

More flexibility around electricity tariffs

Battery storage and smart controls may create opportunities to shift some electricity use to different times.

A more joined up energy system

Heating, generation and storage can be considered together.

A foundation for future changes

Additional electricity demand such as EV charging can be considered as the home evolves.

These benefits depend on the property, household and system design.

They should not be treated as guaranteed financial outcomes.

Independent guidance increasingly considers heat pumps, solar PV, battery storage and smart tariffs together rather than as completely separate technologies.

Energy Saving Trust guidance explains that batteries can store surplus electricity from solar panels and can also work with heat pumps and time of use tariffs.

Its guidance also makes an important practical point.

Solar panels will not always generate electricity at the same time your heat pump needs it.

That is why the grid continues to play an important role.

Battery storage can help shift some electricity within the day, but it cannot move large amounts of summer solar generation into winter.

This is a useful way to think about an integrated home.

The technologies support one another.

They do not remove every limitation of the others.

It can be exciting to start researching heat pumps, solar panels and batteries.

But the best starting point is still the property itself.

Before deciding what to install, ask:

How much heat does the home need?

How much electricity does the household use?

When is that electricity used?

What roof space is available?

What heating system is already in place?

What improvements are planned?

What does the household want to achieve?

The answers determine which technologies make sense.

Renewable Heat’s approach begins with a Home Assessment and looks at heating and energy demand before designing the system.

That might result in an air source heat pump, a ground source heat pump, solar PV, battery storage, underfloor heating, or a combination of these technologies.

The important thing is that the system is designed around your home rather than built from a standard package.

The most interesting part of the all electric home is not any one product.

It is what happens when different technologies are designed to support the same household.

The heat pump deals with heating and hot water.

Solar PV generates electricity.

Battery storage gives you more flexibility over when some of that electricity is used.

Smart controls and tariffs can add another layer of energy management.

And the electricity grid remains available whenever the home needs more energy than it is currently generating or storing.

For some homeowners, all of these technologies will make sense.

For others, only one or two will.

There is no need to install technology simply for the sake of creating an all electric home.

The goal is a comfortable, practical home energy system that suits the property today and can adapt as your needs change.
