Improve your homes energy efficiency!

We can help to reduce your energy bills and benefit form government incentive schemes with a retrofit renewable energy system.

Are you considering replacing your current boiler?

Could you replace your boiler with a heat pump?

Heat Pumps are a fantastic heating solution for people looking to provide hot water throughout their property in a more efficient, environmentally friendly manner.

Using heat pumps as a heating solution is ideal for a range of properties; from flats and small houses, to large detached houses and commercial properties and provide a low cost heating system which is supported by the Renewable Heat Incentive.

We install a range of different heat pumps, but the two most popular options are Ground Source and Air Source.


What does your boiler do exactly?

Boilers work by burning a mixture of gases to heat up your water and radiators, providing heat throughout a property. While this might be convenient, it’s not exactly environmentally friendly, or particularly good when it comes to heating bills either.

If only there was a way of generating your own heat energy instead of relying on fossil fuels…


Can a heat pump replace your boiler?

A heat pump has all the capabilities to provide hot water to heat your entire property, so it is definitely an option to replace your boiler with.

Chancellor Philip Hammond said he wants to stop the installation of gas boilers for water and central heating in new homes from 2025 to reduce greenhouse gases and carbon emissions, so a heat pump is the logical replacement.


How many kilowatt am I currently using per year?

Check your gas bill and it will give you an annual projection of the number of kilowatts you are consuming. As a guide, a standard heat pump generates 7.5 kilowatt of heat – it can do this at an average outside temperature of -3% (more if its hotter, less if its colder).


What’s my first step?

First we recommend getting in touch to let us know you’re interested in learning more about heat pumps and we can go from there.

Following a discussion over the phone or by email the next step is normally to arrange a site visit and consultation. One of the TGG renewable surveyors will arrange an informal site visit to gain an understanding of project.

Following the site survey our renewable energy design gurus will whip up a quotation storm and produce project estimates to meet your requirements. These will normally be emailed over in the first instance where you can review and digest. We are then on hand to answer any questions and of course re-visit the site to run through the project as and when required.


Why choose The Greener Group?

The Greener Group team has a wealth of experience in renewable energy project delivery. We like to start the conversation by gaining an understanding of what your goals for the potential. During initial discussions with the team we will give our view on the technologies you are interested in and answer any initial questions. We always try to give an honest and objective view and call on 9 years of renewable energy experience to guide you.


Before You Start

Work out the heat loss – depends on the age of the build, the older the property and the building regs at the time of the build.

  • How efficient is your insulation?
  • How much heat am I losing?
  • How much heat does the building require?

How To Work Out The Efficiency Of Your Heating System For Your Home

Heart loss value of the materials used to build the property – for example bricks have a heat loss efficiency of 2.8 watts per meter kelvin. Do the same for windows, ceilings, roof and floors.

An average 1970’s 100m2 house with a heat loss of 75 watts per meter squared you would need a 7.5 kilowatt heat pump.


Retrofit Renewable Energy For Homeowners

Starting a new project for your home can be an exciting prospect. However we understand the thought of the journey from start to finish can be a bit daunting and it can be somewhat a leap into the unknown to begin with. That’s why choosing the right project partner early in the process can help take the stress out of it and make it an enjoyable journey.


Project Delivery

On acceptance of the quotation a schedule of works will be discussed and agreed. We will raise a deposit invoice and agree the contract. From there one of the experienced installation team will be assigned the project and a final technical survey arranged if required.

Following technical survey a start date will be agreed and products ordered from suppliers. The installation will be carried out and commissioned.


Handover and Training

Once the installation team have commissioned the system the project lead will provide on site training and a walk through of the system. A handover pack will be produced and delivered to include all warranty information, user manuals and points of contact.
