Is a Heat Pump Worth It?

Heat pumps can provide an efficient, lower-carbon way of heating a home, but they are not automatically the right solution for every property.

Whether a heat pump is worth installing depends on much more than the equipment itself.

The insulation of your home, its heat loss, existing heating system, radiator sizes, hot-water demand, available space and the way you use the property can all affect how successfully a heat pump will perform.

That is why it makes sense to look at the whole property before committing thousands of pounds to an installation.

Is Your Home Suitable for a Heat Pump?

A heat pump works differently from a traditional gas or oil boiler.

Rather than producing very hot water for relatively short periods, heat pumps generally operate most efficiently by providing lower-temperature heat over longer periods.

The energy performance of the building therefore matters.

Before installing a heat pump, it is worth considering:

roof and loft insulation
wall insulation
floor insulation
windows and glazing
draughts and uncontrolled air leakage
existing radiators
underfloor heating
heating controls
hot-water requirements
ventilation
available external and internal space
electrical capacity

The better the building retains heat, the less energy the heating system needs to provide.

Do You Need to Insulate Before Installing a Heat Pump?

Not every home needs to be completely renovated before a heat pump can be installed.

However, improving unnecessary heat loss can reduce heating demand and help the system operate more efficiently.

In some properties, relatively simple improvements such as better loft insulation or heating controls may be worthwhile before changing the heating system.

Older properties with solid walls, suspended timber floors, older glazing or poorly insulated extensions may require a more considered approach.

The important point is not to treat the heat pump as an isolated product.

Will Your Existing Radiators Work?

Heat pumps often operate at lower flow temperatures than conventional boilers.

This means some existing radiators may need to be enlarged or replaced to provide sufficient heat.

In other properties, the radiators may already be suitable.

Underfloor heating can also work very effectively with lower-temperature heating systems, although installing it retrospectively may involve considerably more work.

Understanding the heating requirements of the property before accepting an installation proposal can therefore be extremely valuable.

Air-to-Water or Air-to-Air?

There is more than one type of heat pump.

An air-to-water heat pump can provide heating through radiators or underfloor heating and may also provide domestic hot water.

An air-to-air heat pump provides heated air directly into rooms and can often provide cooling during warmer weather as well.

The most appropriate system depends on the property, your existing heating arrangement, available space and what you want the system to achieve.

For some homeowners, the ability to provide both heating and cooling could make air-to-air technology particularly interesting.

What About Running Costs?

There is no single answer to how much a heat pump will cost to run.

Running costs depend on factors including:

the efficiency of the heat pump
the heat loss of the property
insulation levels
electricity tariffs
required indoor temperatures
heating-system design
flow temperatures
how the home is occupied

A well-designed heat-pump system in a suitable property can perform very differently from an incorrectly sized system installed into a home with significant heat loss.

That is why comparing only the installation cost of a heat pump with the price of replacing a boiler does not tell the whole story.

Should You Get Installer Quotes First?

There is nothing wrong with obtaining quotations from heat-pump installers.

But it is worth remembering that an installer is naturally assessing your property from the perspective of the product they sell.

A heat-pump company wants to install a heat pump.

A solar company wants to install solar panels.

An insulation contractor wants to install insulation.

A window company wants to replace windows.

APN Green Homes takes a different approach.

We do not start with the product. We start with your home.

Our aim is to help you understand what improvements make sense, how they interact with one another and what should come first.

A Heat Pump May Only Be Part of the Answer

Depending on the property, your priorities could include:

improving insulation
reducing heat loss
upgrading windows or glazing
improving ventilation
upgrading heating controls
changing or enlarging radiators
installing underfloor heating
adding solar panels
installing battery storage
upgrading the electrical supply
introducing cooling

Some of these improvements may be worth carrying out before the heat pump. Others may be unnecessary.

That is why a whole-home assessment can be valuable before committing to one particular technology.

Grants and Incentives Could Reduce What You Pay

The availability of financial support is another important reason to investigate your options before committing.

Government grants and other incentives may be available towards heat pumps and other energy-saving improvements, depending on the property, technology and eligibility requirements in force at the time.

That financial support can make a significant difference to the overall cost of a project.

However, schemes change, eligibility varies and different technologies may be treated differently.

As part of your Green Home Assessment, APN Green Homes will consider the grants, incentives and financial support currently relevant to the improvements being recommended for your property.

So before accepting an installer quotation, it makes sense to understand:

what funding may be available
whether your proposed system could qualify
whether other improvements may also attract support
what the likely cost could be after available assistance

The value of identifying suitable financial support could itself be considerably greater than the cost of obtaining independent advice.

Find Out Before You Spend

A heat pump could be an excellent investment for your home.

But before spending thousands of pounds, you should ideally know:

Is my home suitable for a heat pump?
Should I improve the insulation first?
Will my radiators need changing?
Would air-to-air or air-to-water be more appropriate?
Should I consider solar panels or battery storage as well?
What grants or incentives could reduce the cost?

Get Independent Whole-Home Advice

APN Green Homes provides independent Green Home Assessments for homeowners considering significant energy improvements.

Your personalised report looks beyond the individual product and considers the performance of the property as a whole, including:

insulation
walls, roofs and floors
windows and glazing
heating and hot water
ventilation
heat pumps
solar panels
battery storage
cooling
grants and incentives
priorities for future improvements

The objective is simple:

To help you understand whether a heat pump is the right investment, what should come first, and what financial assistance may be available before you commit.
