Elixa Renewables — Low-carbon systems
Low-carbon heating. Designed around your home.
Heat pumps, solar, modern heating systems and intelligent home energy solutions — designed, installed and supported by Elixa Renewables.
Solutions
One home. Every system.
Select a system to look closer — how it works, how efficient it is and what it pairs with. Every figure is refined by a free heat-loss survey before anything is quoted.

Why Elixa
Systems,
not appliances.
A heat pump is only as good as the system around it. Elixa engineers the whole thing — heat source, emitters, controls and the fabric they serve — as one design.
A
System design first
Every proposal starts from the property — heat loss, fabric, flow temperatures — never from a box on a shelf.
B
Correctly sized, every time
Oversized plant short-cycles; undersized plant struggles. We size from the numbers, and we show you the numbers.
C
Low-temperature by design
Emitters chosen so the system runs cool — the quiet discipline behind real heat-pump efficiency.
D
Professional installation
Qualified engineers, tidy first-fix, commissioning that's measured rather than assumed.
E
Support that stays
Monitoring, servicing and a straight answer on the phone — for the life of the system.
Case studies
Built around real homes.
Real projects, written up properly — the brief, the constraints and the decisions. Install photos →
Case study — Cascade heat pumps
Two heat pumps. Three jobs.
A high heat loss property, a full domestic hot water demand and a swimming pool to warm — solved with one intelligently split cascade rather than three separate systems.

Case study — R290 siting
The right spot is everything.
A period cottage, a tight courtyard and an R290 heat pump that has to sit somewhere compliant, quiet and out of the way. Siting designed first, system designed around it.

Technical guide — System volume
Do you actually need a buffer?
Some heat pump systems genuinely need added water volume. Plenty have one fitted that should not. Here is how to tell the difference, and what to ask the installer who is quoting you.

How it works
One line, start to finish.
01
Survey
A proper heat-loss survey of the property — fabric, rooms, existing system.
02
Design
The full system on paper: heat source, emitters, flow temperatures, controls.
03
Installation
Qualified engineers, planned first and second fix, respectful of your home.
04
Commissioning
Measured performance at handover — not assumed. You see it working.
05
Support
Servicing, monitoring and advice for the life of the system.
Grants & funding
Up to
£9,000
Boiler Upgrade Scheme grant towards an air source heat pump when replacing oil or LPG off the gas grid — £7,500 for other eligible homes in England and Wales.
0% VAT
on qualifying energy-saving materials, including heat pumps and solar, until 2027.
We handle it
Elixa checks eligibility and applies for the grant as part of your quote — the price you see is after funding.
No pressure
About the schemes The survey and design come first. Funding is applied to a system that's right, not the other way round.
