A ‘Cosy’ Home Upgrade in Grantham

Our customer, Johnathan Bowman-Perks MBE, a renowned global leadership coach, podcaster, and motivational speaker, has now gone “completely renewable” after installing the new Octopus Cosy at his home in Grantham. As an Octopus Trusted Partner and a Cosy accredited installer, Egensys is one of a select few companies currently accredited to install this innovative new heat pump for Johnathan.

the objectives

In this home upgrade, Johnathan aimed to enhance his home’s energy efficiency and reduce his reliance on fossil fuels. The goal was to take out his old gas boiler and incorporate a renewable heating system that supports his environmentally conscious lifestyle. He already had an existing sustainable set-up with solar panels, battery storage and electric vehicles, but wanted to make the most of ongoing government grants by making the transition to a fully renewable ecosystem. By integrating an air source heat pump, Johnathan can:

Take advantage of his self-generated and stored electricity to heat his home and hot water
Eliminate his reliance on traditional gas heating
Lower his energy bills through efficient, eco-friendly technology
Achieve a sustainable and self-sufficient home environment

what we delivered

Egensys supplied and installed this innovative energy solution:

octopus energy cosy 12kW air source heat pump

hot water cylinder

full project coordination

how we delivered

We first began with a comprehensive assessment of Johnathan’s property to determine the most effective heat pump system for his needs.

Johnathan wanted to ensure his household could operate mostly on renewable energy, especially given the rising costs of gas. Because of this, we recommended The Cosy to him. With the Cosy, he can take advantage of Octopus smart energy tariffs and get access to the most efficient and cost-effective heating. This pump is one of the very few on the market that interacts directly with the energy supplier to work at peak efficiency all the time. Since he already uses Octopus Energy as his energy supplier, it’s even easier for Johnathan to manage and optimise his energy use, making the most of the renewable energy generated and stored.

“I already use Octopus as my energy supplier, and I like the values that they have. I trusted their innovation in this system, as well as Egensys’ advice for my home and decided to install a Cosy”

the results

reduced reliance on gas
better use of self-generated electricity
a more joined-up renewable set-up
lower upfront cost through grant support

What to expect from a

Solar PV & Battery Quote

Egensys are often able to provide a basic quote remotely, using information you provide us alongside our design software that takes advantage of satellite imagery. However, we feel that the best option is for us to undertake a free, no obligation, site survey. Our project manager will contact you to arrange a convenient time slot of around 45 minutes.

In a typical survey, the engineer will firstly need access to your electricity meter, consumer unit (fuseboard), loft and potentially any other void spaces within the building. They will discuss the location of the equipment and agree potential cable routes.

Once locations and routes have been assessed, it will be your opportunity to discuss system size and specifications, based on our building survey we will be able to provide feedback on compatibility and suitability. It would be beneficial for this discussion if you were to have a recent electricity bill available, which details expected annual consumption in kWh (units), also please let us know if you plan to add high usage items in the future like, hot tubs, electric cars and heat pumps/air conditioning.

Our engineer will return to the office to build a detailed site specific quote with potentially several system options of different sizes and manufacturers, providing you with a choice to meet your preference and budget. We do not try to secure a sale while on site.

The quote will be emailed over to you and will include, calculations detailing generation, expected savings, payback periods and finance options, if required. We will contact you over telephone or email to confirm you have received the quote and that you are happy with the information provided. Feel free to get in touch as much as you need to ask us any questions or provide alternative options.

Once we have confirmed the quote has been received, we will not contact you again unless you get in touch with us. There will be no hard sales and no constant chasing for a decision. We do hope you choose us! but understand that you may need time to think about it or consider alternatives, it’s a large commitment and should not be taken lightly or be pushed into.

What to expect from a

air source heat pump Quote

If you have full building plans detailing  insulation levels Egensys are often able to provide an initial quote remotely using our design software. However, if pans are not available and to be thorough we feel that the best option is for us to undertake a free, no obligation, site survey. Our project manager will contact you to arrange a convenient time slot of around 60 minutes.

In a typical survey, the engineer will firstly need access to your existing boiler and cylinder locations, electricity meter, consumer unit (fuseboard), external areas, loft and potentially any other void spaces within the building. They will discuss the location of the equipment and agree potential cable and pipe routes.

If building plans are not available beforehand we will need to do a room by room heat loss survey, this involves taking measurements of room dimensions, window sizes, and radiator sizing. Access to every room will be required for this process, the results of which enable us to accurately predict the heat loss of the building, size the system correctly and calculate if the existing heating system (radiators, UFH, pipework) needs any alterations. At this stage, please let us know if you plan and changes to the building, extensions, new windows, extra insulation etc.

Once locations and routes have been assessed and a heat loss survey completed, the engineer will be able to give an indication of equipment options and it will be your opportunity to discuss system size and specifications and how it will operate. Our engineer will then return to the office to complete the heat loss calculation, build a detailed site specific quote with potentially several system options from different manufacturers, providing you with a choice to meet your preference and budget. We do not try to secure a sale while on site.

The quote will be emailed over to you and will include, calculations detailing energy consumption, expected savings, and separate prices for any suggested system upgrades, such as replacement radiators. We will contact you over telephone or email to confirm you have received the quote and that you are happy with the information provided. Feel free to get in touch as much as you need to ask us any questions or provide alternative options.

Once we have confirmed the quote has been received, we will not contact you again unless you get in touch with us. There will be no hard sales and no constant chasing for a decision. We do hope you choose us! but understand that you may need time to think about it or consider alternatives, it’s a large commitment and should not be taken lightly or be pushed into.
