Should I have an air or ground source heat pump?

How they work?

Air source heat pumps work by extracting heat from the outside air, and a ground source heat pump takes heat from the earth.

The heat from either can then be used to heat the home. Via radiators, underfloor heating systems and they can provide hot water.

Should I choose a air or ground source heat pump?

They are a few factors that you will need to consider when choosing between an air source heat pump or a ground source heat pump, the two mainly being budget and outdoor space.

Ground source heat pumps require the ground to be dug, so it is a more timely and expensive option compared to an air source heat pump, however this means that you will not be able to see any equipment on the outside of your property. The benefits of an air source heat pump are that it is quicker and cheaper to install, as they do not require any land to be dug up. Though they will be mounted on the outside of your property, they look a bit like air conditioning units.

What are the benefits of heat pumps?

  • Low running costs
  • Reduces carbon emissions
  • Safer systems
  • Provide cooling
  • Long life span
  • Grants available for installation

Our installers will be able to discuss all of this with you in detail to help find you the right solution. Contact us today:

The Boiler Upgrade Scheme is a new incentive launched by means of the UK Government to motivate the set up of low-carbon heating systems, such as warmth pumps, over fossil gas boilers.

The scheme is presenting capital provides of £6000 to assist limit the value for households of putting in eco-friendly heating systems. This upfront supply can make the choice of selecting renewable electricity or even less expensive than putting in a fossil gasoline boiler!

With this new scheme, the Government is persevering with to supply extra incentives to improve these choice options via drastically decreasing the preliminary value and installation. Making low carbon heating an extra low-priced and attainable choice for house owners or businesses.

The Boiler Upgrade Scheme alongside the low going for walks value and preservation of warmness pumps make them financially attractive as nicely eco-friendly!


The funding on the scheme is designed to assist house owners to find the money for the upfront charges of low-carbon technologies, such as floor supply warmness pumps and biomass boilers.

Ministers have additionally stated that they hope the scheme will assist to develop purchaser self-assurance in the applied sciences available, in order to improve enterprise demand.

The scheme is a necessary side of supporting the authorities meet its internet zero-emissions goal through 2050, and to assist segment out fossil gas heating in properties of the fuel grid, the authorities has said.


Due to climate change, the UK Government is trying to extensively reduce carbon emissions, and changing old, inefficient boilers with modern, A-rated fashions is simply one way they can make a sizeable reduction.

In addition, the effectiveness of current boilers ability they are less expensive to run, considerably supporting to minimize the heating payments of low-income households and these at danger of gas poverty.

However, for many households, the value of obtaining a new boiler can be big and it’s, for this reason, the Government and some of the greatest electricity corporations in the UK grant boiler grants. These allow households to accumulate a backed boiler and, in some cases, a free boiler.

Solar turns this garage into an energy generating hub to provide the whole home with clean, green power

Garage & outbuilding roofs can be an ideal & discreet place for installing solar panels, particularly if you’ve been put off installing them on your house roof for aesthetic reasons.

For this customer in Shrewsbury his slate roofed garage was the perfect spot for installing his new solar array, & is made even more discreet thanks to the use of roof integrated panels.

Our installers carefully removed the slates to install the GSE mounting modules before reinstating & sealing to ensure the roof is watertight.

Ten Jinko 3.2kW panels were installed complete with maximisers, along with a Solis inverter.

On this install our team opted for the award winning GivEnergy battery system with hybrid inverter.  This storage system is able to provide back up power in the event of a black out & charge directly from the solar PV & the grid utilising a flexible energy tariff.  As you’d expect from the latest technology the system has built in WiFi & the customer can monitor through the cloud via the web or an app. 

As you can see, the battery & inverter take up very little space within the garage so you’d hardly know it was there!  This install has turned the customers garage into a discreet, clean energy producing ‘hub’ to power the whole home! 

Seamless, integrated solar PV roof installation & the latest Myenergi technology

We’ve just finished this solar PV installation at this beautiful cottage in Market Drayton.  What makes this install really special is that the panels have been seamlessly integrated into the roofing tiles, sitting flush with rather than on top of the roof as with traditional solar arrays.

To achieve this our team removed the roof tiles to expose the roof battens in the area where the panels were to be installed.  They then fitted the innovative GSE roof mounting system to the batten, with flashing system to ensure the roof is weatherproof, before reinstating the tiles.

GSE Integration is an in-roof mounting system, allowing the building integrated installation of standard solar panels on new builds or roof-renewal properties. The system has the advantage that it fits with most solar PV panels available on the market.

Photovoltaic modules can be installed in all roof types.

The panels themselves are fitted with solaredge optimisers & an inverter to provide superior efficiency, optimise energy output & minimise shading.  This clever design also means each panel can be monitored individually.

To make use of all their clean, green energy the customer also opted for an electric vehicle charger.

We installed the super ingenious & award winning Myenergi Zappi car charger along with their Harvi, an energy harvesting wireless sensor.  This intelligent device allows the Zappi to be installed without the need for a hardwired transformer.  To make this install fully ‘smart’ & to provide the other devices with internet we used the Myenergi hub which works with an app & allows the customer to control their system from anywhere in the world!

Stunning self powered, sustainable new build in Whitchurch

Our team are starting the New Year by adding the final touches to this beautiful new build property in Whitchurch.

The customer contacted us asking for renewable energy options prior to the construction of their build.  We recommended & have now installed an air source heat pump complete with unvented heat pump cylinder & a full underfloor heating system.

To complement the heating system & to make this stunning property a fully self-powered home we installed a solar PV roof integrated system, with inverter & a Tesla Powerwall to enable the client to store the energy from the panels & continuously power their home day & night.  This home will be fully sustainable & capable of fuelling itself with clean energy 24/7 even in the event of a grid outage! 

Our renewable technology & low carbon installation includes:

  • Samsung air to water heating (EHS) air source heat pump installation comprising of 300ltr unvented heat pump cylinder
  • Underfloor heating system zoned accordingly & consisting of staple type on ground floor & spreader plate on first floor complete with all pipework, manifolds, pumps, actuators & Neo smart control stats
  • Roof integrated 6kW solar PV array with 10kW solar Edge inverter to harvest & convert the energy from the sun
  • Tesla Powerwall battery system to enable the customer to store & consume their own clean, green energy
  • Commissioning & handover pack with MCS documentation to support RHI application

We are particularly proud of this project because as well as providing the renewable energy systems we also completed all of the electrical & plumbing first & second fix work at this property.  Our skilled team of plumbers & electricians made an amazing job of the full package which included:

  • Exterior lighting & power to electric gates
  • LED downlights throughout with dimmer switches
  • Kitchen electrical installation with supply to AGA & power to kitchen island including decorative pendant lighting & USB sockets
  • Data cabling & USB sockets throughout
  • Dimmable suspended feature lighting in glazed gable apex above piano
  • CCTV system
  • Honeywell intruder alarm system with pet PIR detectors & panic button
  • All plumbing & heating works to complement heat pump installation including fitting of hot & cold pipework from hot water cylinder to bathrooms, ensuites, kitchen & utility as well installation of all sanitary ware & towel rails.

We think this home looks absolutely stunning & we can’t wait to see it when the ground works are finished.  It’s a real achievement by the whole team who were involved, from planning stages right through to handover. 

Eco friendly heating system & solar technology for home in Whitchurch

The team at Princes LHS have just finished the design & installation of an air source heat pump & solar array at this property in Whitchurch.

The customer got in touch with us for an assessment to see how installing an air source heat pump could benefit them.  They were currently fully reliant on a condensing gas boiler.  Following our technical survey & EPC assessment we calculated that by installing a 16KW Samsung air source heat pump the customer could save in excess of £10,000.00 over a 7 year RHI period! 

We also advised the customer that a hybrid set up would be beneficial, so in this instance the existing relatively new gas boiler was to stay in place & the system will automatically switch over from the heat pump in the event that the temperature drops below 2 degrees celcius.  This meant that the customer did not need to upgrade all of their radiators & kept disruption to a minimum, plus there is always the option to remove the gas boiler in the future & allow the heat pump to provide all of the heating requirements.

Our customer also decided to go ahead with the installation of 5.58KW Solar PV system complete with a fully intergrated Tesla Powerwall home battery to store clean energy for use at any time, & a Myenergi eddi energy management system to divert excess power from the PV to the hot water system.  Excess energy can also be exported back to the grid to save the customer even more on their energy bill!

We’re really happy with how this installation has turned out & more importantly so is our customer who has already started saving on their energy bills & significantly reducing their carbon footprint!

Choosing a Solar Battery for Your Home

Whilst being relatively new technology, solar batteries do have the ability to significantly reduce your reliance on fossil fuels. Savings of up to £300 a year can be achieved on a standard 4 Kw solar system. This will be suitable for a domestic property, whether you live in a bungalow or a larger property.

Why choose solar batteries?

Currently a typical solar PV system will send energy back to the grid at a decreased rate. This increases your reliance on the grid and can reduce your overall energy savings. By deciding to install a battery storage system you increase self-sufficiency up to almost 100% and significantly reduce the running costs of your solar system.

Battery systems can also be easily installed alongside existing solar systems with wall mounted and ground mounted versions available. The digital display available on most models will give you an idea of performance as well.

Types of solar batteries

There are two types of solar battery systems that can be installed currently. These include lithium acid and lithium ion batteries, which both differ in price and performance. Whilst lithium acid models may be typically a third of the cost of a lithium ion battery, a lithium ion battery is a much longer lasting and powerful. For instance, a lithium ion battery can discharge at a rate of 90% while a lithium acid battery can only discharge at roughly 50% of its capacity.

The truth is lithium-ion batteries generally have more energy , last longer and operate at a range of temperatures unlike other rechargeable batteries.Whilst standard batteries for running computers, mobile phones and other consumer electronics, these batteries have the density and longevity to store and dispatch solar electricity for at least 10 years.

The rise of lithium ion

Tesla is using Panasonic’s lithium-ion batteries for its cars and they recently flipped the switched on their giggafactory which is set to double the worlds production of lithium ion batteries. Tesla are well known for setting ambitious and unrealistic timelines for their renewable s projects, and Elon Musk has once again pulled it off by putting the factory live on schedule
