What Is Smart Heating?

 

Smart heating describes heating controls that provide greater automation, programming and individual control than a conventional thermostat.

​

A smart heating system may include:

​

• a central smart thermostat;

• programmable heating schedules;

• smart radiator thermostats;

• individual room temperature control;

• smartphone or tablet control;

• heating zones;

• occupancy detection;

• weather-responsive controls;

• energy monitoring; and

• integration with other smart-home equipment.

​

The purpose is not simply to control the heating from your phone.

​

The real benefit is the opportunity to heat the right parts of the home, at the right temperature, at the right time.

​

​

What Is a Smart Thermostat?

 

A smart thermostat controls the heating system in much the same way as a conventional thermostat, but with additional programming, monitoring and remote-control functions.

​

Depending on the system, a homeowner may be able to:

​

• change the temperature remotely;

• set different heating schedules;

• create heating zones;

• monitor heating patterns;

• respond to changes in occupancy;

• control individual radiators; and

• integrate heating with other smart-home systems.

​

Some smart thermostats can also adapt to household routines or respond to external weather conditions.

​

The level of functionality varies considerably between different products.

​

​

Can a Smart Thermostat Save Energy?

 

Potentially, yes.

​

The main opportunity comes from reducing unnecessary heating rather than from the thermostat itself somehow producing heat more efficiently.

​

For example, smart controls may help avoid:

​

• heating an empty house;

• heating unused bedrooms;

• leaving the heating on longer than necessary;

• maintaining unnecessarily high temperatures;

• heating every room to the same temperature; and

• operating the system inefficiently around household routines.

​

The amount saved will depend heavily on how the heating was controlled before the smart system was installed.

​

A home that already has carefully managed heating may see a smaller difference than one operating with basic or poorly configured controls.

​

​

Smart Thermostats

 

There are many types of smart thermostats available for UK homes.

​

Homeowners frequently compare systems associated with brands such as:

​

• Hive;

• Google Nest;

• Tado; and

• Drayton Wiser.

​

Different systems approach heating control in different ways, so the best choice should depend on the existing heating system and what you actually want the controls to achieve.

​

At APN Green Homes, we would not normally recommend choosing a smart heating system purely because one brand is well known. Compatibility, zoning, radiator control and future heating plans are more important.

​

​

Hive Thermostat

 

The Hive thermostat is one of the smart heating systems homeowners commonly research when looking to replace traditional heating controls.

​

The important question is whether the proposed controls are suitable for the existing boiler, heating zones and radiators.

​

For some households, simple central control may be sufficient.

​

Others may benefit from combining the main thermostat with individual smart radiator controls to create greater room-by-room flexibility.

​

​

Hive Radiator Valves

 

A Hive radiator valve or other smart thermostatic radiator valve can potentially allow individual rooms to be controlled separately.

​

This can be useful where different parts of the house are used at different times.

​

For example:

​

• bedrooms may require heating mainly in the morning and evening;

• a home office may need heat during working hours;

• a guest bedroom may rarely require heating;

• living spaces may be used mainly during the evening; and

• bathrooms may require short periods of additional warmth.

​

Room-by-room control can reduce the need to heat every part of the property whenever the central heating operates.

​

​

Google Nest Thermostat

 

The Google Nest thermostat is another system commonly considered by homeowners looking for smart heating control.

​

Smart thermostats of this type can provide more flexible scheduling and remote control than a traditional thermostat.

​

Where a homeowner is considering Nest heating or another similar system, the wider question should be whether central thermostat control alone is sufficient or whether individual room control would provide additional benefit.

​

The most sophisticated controls are not necessarily required in every property.

​

​

Tado Smart Thermostat

 

A Tado smart thermostat is another commonly searched option within the smart heating market.

​

Systems in this category can be particularly attractive where homeowners want greater room-by-room control using smart radiator thermostats as well as a central heating controller.

​

As with any smart heating system, compatibility with the existing boiler, heating layout and future plans should be checked before equipment is purchased.

​

​

Tado Smart Radiator Thermostats

 

A Tado smart radiator thermostat, or similar smart TRV, can allow the temperature and schedule of individual radiators to be controlled.

​

This can create much more detailed heating zones without necessarily replumbing the entire central heating system.

​

Smart radiator controls can be useful in larger homes where different rooms have very different usage patterns.

​

However, the system needs to be configured properly so that radiator controls, boiler demand and the central heating system work together.

​

​

Drayton Wiser

 

Drayton Wiser is another smart heating system homeowners may encounter when comparing controls.

​

As with Hive, Nest, Tado and other alternatives, the important issue is not simply the brand name.

​

Homeowners should consider:

​

• compatibility with the heating system;

• number of heating zones;

• smart radiator controls;

• ease of use;

• app functionality;

• future support;

• installation requirements; and

• whether the controls will remain suitable if the heating system changes later.

​

A Green Home Survey can help put the control system into the context of the wider home energy plan.

​

​

Smart Radiator Thermostats

 

A smart radiator thermostat replaces or works with the control normally provided by a conventional thermostatic radiator valve.

​

It allows the temperature of an individual room to be controlled according to a schedule or smart-home command.

​

This can be particularly useful in properties with:

​

• several bedrooms;

• home offices;

• guest rooms;

• rooms used only occasionally;

• different occupancy patterns; and

• large differences in temperature between parts of the house.

​

The objective is to avoid heating rooms simply because another part of the property needs heat.

​

​

Heating Zones

 

Zoning divides a property into areas that can be heated independently.

​

A simple home may have separate upstairs and downstairs zones.

​

More sophisticated smart heating systems can provide room-by-room control.

​

Possible zones might include:

​

• living areas;

• bedrooms;

• home office;

• kitchen;

• bathrooms;

• extension;

• loft conversion; and

• guest accommodation.

​

The appropriate level of zoning depends on the property and how it is occupied.

​

Too much unnecessary complexity can be just as frustrating as controls that are too basic.

​

​

Programmable Thermostats

 

A programmable thermostat allows temperatures and heating periods to be scheduled in advance.

​

Smart thermostats extend this concept by adding features such as remote access, adaptive programming, zoning or integration with other systems.

​

For some properties, a good programmable thermostat may provide all the control that is required.

​

For others, a more sophisticated smart heating system may justify the additional cost.

​

The important point is to select controls that the household will actually understand and use.

​

​

Smart Heating and Insulation

 

Smart controls can reduce unnecessary heating, but they cannot compensate for a property that loses large amounts of heat through poorly insulated walls, roofs or floors.

​

A draughty house may still require substantial energy regardless of how intelligent the thermostat becomes.

​

This is why APN Green Homes considers heating controls alongside insulation and the building fabric.

​

In some homes, upgrading the controls may provide a useful early improvement.

​

In others, insulation should be the greater priority.

​

​

Smart Heating and Energy Efficient Windows

 

Glazing can also affect how quickly individual rooms lose heat.

​

A room with older glazing or significant draughts may cool much faster than another part of the home.

​

Smart heating controls can help manage different temperature requirements, but they should not disguise underlying problems with the building fabric.

​

Window improvements, insulation and heating controls can often work together to create more consistent internal temperatures.

​

​

Smart Heating and Heat Pumps

 

Smart controls can become particularly important where an air source heat pump is installed.

​

Heat pumps often operate differently from traditional boilers.

​

A conventional boiler may provide relatively high-temperature heat for short periods, while a heat pump can work more efficiently by maintaining lower and more consistent temperatures.

​

Controls designed around repeated short bursts of high-temperature heating may therefore not be ideal for a heat-pump system.

​

Where a future heat pump is being considered, it is sensible to think about whether the proposed smart heating controls will remain suitable.

​

​

Smart Heating and Underfloor Heating

 

Underfloor heating also responds differently from conventional radiators.

​

The floor itself stores heat, which means the system may take longer to warm up and cool down.

​

Smart controls can help manage this response, but programming needs to reflect the characteristics of the system.

​

Trying to operate underfloor heating exactly like a conventional radiator system may result in unnecessary temperature swings or poor comfort.

​

​

Smart Heating and Solar Panels

 

Solar panels primarily affect electricity generation rather than heating control, but the systems can become increasingly connected as homes move towards electric heating.

​

A property with:

​

• solar panels;

• battery storage;

• a heat pump;

• electric hot water; and

• smart heating controls

​

may eventually be able to coordinate when electricity is generated, stored and used for heating.

​

The home energy system therefore becomes much more interconnected than the traditional combination of a gas boiler and simple thermostat.

​

​

Smart Heating and Battery Storage

 

Battery storage can also influence when electricity is most economical to use.

​

Where electric heating or a heat pump is installed, smart controls may work alongside:

​

• solar generation;

• battery charge levels;

• time-of-use tariffs;

• household electricity demand; and

• weather conditions.

​

This creates opportunities to manage both comfort and energy cost.

​

The potential benefits increase as more of the home becomes electrically powered.

​

​

Weather Compensation

 

Weather compensation adjusts heating operation according to the outside temperature.

​

When conditions are mild, the heating system may not need to operate at the same temperature as it would during very cold weather.

​

This can be particularly useful for systems designed to work efficiently at lower temperatures.

​

Weather-responsive control can therefore form part of a more sophisticated heating strategy, particularly with heat pumps.

​

​

Smart Heating Schedules

 

One of the simplest benefits of smart heating is the ability to create more detailed schedules.

​

Instead of operating the whole property according to a basic morning-and-evening programme, different rooms can potentially follow different routines.

​

For example:

​

6:30am: bedrooms and bathroom warm.

​

8:00am: bedrooms reduce while home office warms.

​

5:00pm: living spaces begin heating.

​

10:30pm: living areas reduce and bedrooms maintain comfortable temperatures.

​

The exact programme should reflect the household rather than forcing the household to adapt to the heating system.

​

​

Remote Heating Control

 

Smart heating systems commonly allow homeowners to control the heating remotely.

​

This can be useful if:

​

• you return home earlier than expected;

• you are away for several days;

• holiday plans change;

• a room is being used unexpectedly; or

• you want to check whether the heating has been left on.

​

Remote control is convenient, although it should be viewed as an additional benefit rather than the main reason for installing smart heating.

​

​

Smart Heating for Larger Homes

 

Larger homes can particularly benefit from zoning because it may be unnecessary to heat every room whenever the property is occupied.

​

Guest bedrooms, studies, separate dining rooms and other spaces may be used relatively infrequently.

​

A smart heating system can potentially allow these areas to remain at lower temperatures until required.

​

This can provide much greater control than relying on one thermostat positioned in a hallway.

​

​

Smart Heating for Extensions

 

An extension can create a useful opportunity to review the heating controls for the whole property.

​

The new space may have:

​

• underfloor heating;

• different insulation levels;

• large areas of glazing;

• separate heating demand; or

• a different pattern of use from the original house.

​

Rather than simply connecting the extension to the existing heating controls, it may be worth creating a separate heating zone.

​

This can improve both comfort and control.

​

​

Smart Heating During a Renovation

 

A major refurbishment is one of the best opportunities to consider smarter heating.

​

If radiators, pipework, wiring, heating systems and floors are already being changed, controls can be incorporated into the wider design.

​

The project may allow consideration of:

​

• heating zones;

• smart radiator valves;

• underfloor heating controls;

• heat-pump controls;

• room thermostats;

• hot-water control;

• electrical infrastructure; and

• smart-home integration.

​

Planning these elements together can produce a more coherent system than adding separate smart devices later.

​

​

How Much Does Smart Heating Cost?

 

The cost of smart heating depends on the level of control being introduced.

​

A single smart thermostat can represent a relatively modest upgrade.

​

A whole-house system involving smart radiator thermostats throughout the property can cost considerably more.

​

The total price may depend on:

​

• thermostat system;

• number of radiators;

• number of heating zones;

• installation;

• wiring alterations;

• boiler compatibility;

• underfloor heating;

• smart-home integration; and

• additional control equipment.

​

The cost should be considered against the level of additional control the household will actually use.

​

​

Do Smart Thermostats Need Professional Installation?

 

Some smart heating products are designed for relatively straightforward installation, while others require changes to boiler controls or electrical wiring.

​

Where the equipment interfaces directly with the heating appliance or mains electrical system, professional installation may be appropriate.

​

The installer should also ensure that the system is configured correctly.

​

A sophisticated smart thermostat that has been badly programmed may offer little advantage over a conventional control.

​

​

Is Smart Heating Worth It?

 

Smart heating can be worthwhile where greater control can reduce unnecessary heating or improve comfort.

​

It may be particularly useful for:

​

• larger homes;

• households with changing routines;

• home workers;

• properties with unused rooms;

• multi-zone heating systems;

• extensions;

• homes with underfloor heating; and

• properties moving towards electric heating.

​

For a small home with a simple routine and well-managed existing controls, the potential savings may be more modest.

​

The value therefore lies in matching the controls to the way the property is actually used.

​

​

Smart Heating as Part of a Green Home Plan

 

Smart heating is one component of a wider home energy strategy.

​

Insulation reduces the amount of heat the property needs.

​

Energy efficient windows reduce heat loss and draughts.

​

Smart heating controls determine where and when heat is supplied.

​

A heat pump can provide low-carbon heating.

​

Solar panels can generate electricity.

​

Battery storage can help manage electricity consumption.

​

Smart tariffs can influence when electricity is cheapest to use.

​

Bringing these measures together can make the home considerably more responsive and efficient.

​

​

Independent Smart Heating Advice

 

Heating-control manufacturers naturally focus on the features of their own systems.

​

APN Green Homes takes a whole-home approach.

​

Through a Green Home Survey, we can consider whether improved heating controls should be a priority, whether room-by-room zoning would be worthwhile and how smart heating fits alongside insulation, glazing, heat pumps, solar panels and other planned improvements.

​

For some homes, smart controls may offer an immediate and relatively simple upgrade.

​

For others, changes to the building fabric or heating system may deserve attention first.

​

The aim is to establish what will make the greatest difference to your particular property.

​

​

Start With How You Use Your Home

 

The smartest heating system is not necessarily the one with the most technology.

​

It is the system that provides the right temperature in the right rooms without wasting energy elsewhere.

​

Before selecting smart thermostats or radiator controls, it makes sense to understand how your home is occupied, how efficiently it retains heat and how your heating requirements may change in the future.

​

​
