Professional Air Source Heat Pump design and installation for homes across Hertfordshire and the South East.
NCS designs each system around the individual property, using detailed heat-loss calculations, emitter assessments and hot-water requirements to create an efficient, dependable low-carbon heating solution.
An Air Source Heat Pump extracts heat energy from the outside air and transfers it into your home's heating and hot-water system.
Unlike a traditional boiler, a heat pump does not need to generate all of its heat by burning fuel. Instead, electricity powers the refrigeration cycle that moves available heat from outside into the property.
Because heat pumps normally operate at lower water temperatures than traditional boilers, good system design is essential.
NCS therefore looks beyond simply choosing an outdoor unit. We assess the property's heat loss, radiators or underfloor heating, hot-water demand, electrical supply and the proposed system operating temperature before preparing the final design.
Air Source Heat Pumps can provide a modern alternative to gas, oil, LPG and direct-electric heating when the system and property are correctly assessed and designed.
Heat pumps transfer available heat rather than relying solely on electrical resistance or combustion to produce it.
A correctly designed air-to-water heat pump can provide both space heating and domestic hot water.
Moving away from traditional fossil-fuel heating can significantly reduce the carbon impact of your home.
A heat pump can form part of a wider home-energy system alongside Solar PV, battery storage and smart tariffs.
There is no sensible one-price-fits-all figure for a properly designed heat pump installation.
The final price depends on the home, the heating demand and how much of the existing heating system needs to be adapted.
NCS therefore starts with an initial property assessment before progressing to a detailed survey, heat-loss calculation and final proposal.
Eligible properties in England and Wales can currently receive £7,500 towards the cost and installation of an air-to-water heat pump through the Boiler Upgrade Scheme.
Until 31 March 2027, qualifying off-gas-grid homes currently heated by oil or LPG may be eligible for £9,000 support.
The scheme is installer-led. As an MCS-certified installer, NCS can guide eligible customers through the relevant application process.
Yes, in many homes it can. Installing a heat pump does not automatically mean that every radiator needs replacing.
Heat pumps generally work most efficiently at lower flow temperatures than conventional boilers. The heat output required from each radiator therefore needs to be checked against the room's calculated heat loss.
Some existing radiators may already be suitably sized. Others may need to be upgraded to a larger or higher-output emitter.
This is why NCS carries out room-by-room heat-loss calculations rather than making assumptions based only on the overall size of the property.
We calculate whether existing emitters can provide the required room output at the proposed flow temperature.
Where necessary, larger or higher-output radiators can be specified to achieve the required performance.
Low-temperature underfloor heating can work particularly well as part of a correctly designed heat pump system.
A successful heat pump installation begins long before the outdoor unit arrives. The design process determines how effectively the complete heating system will perform.
Tell us about the property and your current heating system using our online assessment.
We inspect the building, heating system, hot-water arrangements and suitable equipment locations.
Room-by-room calculations establish the heat requirement of the property and each individual space.
Existing radiators or underfloor heating are checked against the proposed system temperatures.
We specify the heat pump, hot-water storage, emitters, controls and supporting system components.
Where applicable, we assist with the installer-led Boiler Upgrade Scheme process.
Our engineers install, test and commission the complete heating system ready for use.
We explain the controls, system operation and remain available for ongoing support and servicing.
A heat pump should be selected around the calculated requirements of the property rather than simply replacing a boiler on a like-for-like kW basis.
Oversizing or undersizing can affect comfort, efficiency and system operation.
Our design therefore considers the complete heating system, including the desired flow temperature, required emitter outputs, hot-water demand and how the property is actually used.
This approach allows us to recommend a solution based on the home rather than trying to make the home fit a predetermined piece of equipment.
Every property presents different design and installation requirements. Here are a few examples of genuine NCS Air Source Heat Pump projects.
Heat pumps may be a newer heating technology for many homeowners, but successful installation still depends on understanding heating systems, hydraulics, controls, electrical requirements and the building itself.
NCS provides Air Source Heat Pump surveys, design and installation across Hertfordshire and surrounding parts of the South East.
Yes. A correctly sized and designed air-to-water heat pump can provide whole-home space heating. It can also provide domestic hot water when designed with suitable hot-water storage.
Not necessarily. NCS calculates the heat requirement of each room and checks the output of the existing radiator at the proposed heat-pump flow temperature. Some radiators may be suitable while others may need to be increased in size or output.
Yes. Underfloor heating is often particularly well suited to lower-temperature heating systems because of its large heat-emitting surface area. The actual design still needs to be checked against the property's heat loss and floor construction.
NCS carries out room-by-room heat-loss calculations and considers the building fabric, design temperature, emitters, hot-water demand and proposed operating temperatures before selecting the equipment.
Installation costs vary considerably between properties. Heat-pump size, hot-water storage, radiator upgrades, electrical works, pipework alterations and installation complexity all affect the final price. NCS prepares a property-specific proposal following the relevant assessment and survey.
The Boiler Upgrade Scheme provides government support towards eligible low-carbon heating installations in England and Wales. Eligible air-to-water heat pumps currently receive standard support of £7,500, with enhanced support available for certain qualifying off-gas-grid properties.
Potentially, yes. Heat pumps can provide an alternative to oil heating where the property and heating system are suitable. A full survey and heat-loss calculation are required to establish the appropriate design.
Yes, subject to the individual property being suitable. The design needs to consider heat loss, available emitter output, domestic hot-water requirements, outdoor-unit positioning and electrical requirements.
Modern Air Source Heat Pumps are designed to operate at low outdoor temperatures. Correct equipment sizing and system design are particularly important to ensure the required heat output is available during colder weather.
Yes. Heat pumps, Solar PV and home battery storage can form part of a wider low-carbon home-energy system. NCS can assess these technologies individually or as part of a coordinated home-energy project.
Complete our free initial assessment and tell us about your property. We can then help you understand the likely system requirements, available support and next steps.
Boiler Upgrade Scheme eligibility is subject to the applicable scheme rules and individual property circumstances. Standard support for an eligible air-to-water heat pump is currently £7,500. Until 31 March 2027, qualifying off-gas-grid properties heated by oil or LPG may be eligible for £9,000 support. Final installation costs, system performance and potential savings depend on property heat loss, equipment specification, heating-system design, energy tariffs and household usage.
