Residential Refurbishment

GDHV has a range of solutions designed to help building professionals update HVAC systems in residential dwellings. We can offer end-to-end heating, cooling, hot water and ventilation solutions, incorporating renewable energy sources where required, in order to deliver better performing spaces.

Specification Support:

We aim to be on hand from initial specification through to product design and installation training. Our aim is to give you peace of mind alongside an effective HVAC solution.

Specification support

Our team of specialists have extensive experience in specifying new HVAC systems to improve a dwellings performance and energy efficiency. Whether you’re looking to refurb an existing solution or retrofit in a new one, speak to us and we can help.

Design support

The GDHV Application Design Team can provide you with an initial design recommendation for applying our solutions to your project. This service includes the sizing of a range of our products, including heat pumps, high heat retention storage heaters and hot water cylinders.


We offer a range of CPDs specific to the design, specification and installation of HVAC solutions and related regulations. These can be booked directly on our CPD page.

Training programs

For those looking to specify, install or just understand our products in greater detail, we offer a range of BPEC and non-BPEC training courses which can be delivered at one of our six training centres or at a site to fit you.


At GDHV we understand that every refurbishment project is different and there is not a one size fits all process. Each specification will be carefully driven by the dwelling type, any local planning requirements and the most cost-effective way to improve the buildings efficiency whilst maximising occupant comfort.
