Installation of Air source heat pumps and heating systems to 5 new houses in Surrey 

Mechanical Installations

We installed Air source heat pumps to the garden, These were Daikin Altherma air to water units.

Interlink pre insulated pipe has been under the ground rising in to the houses to the cylinder cupboard.

Horizontal hot water storage cylinders were required to maximize the habitable space.

Under floor heating to the ground floor separately controlled per room with radiators to the upper floors.

The system also incorporated Weather compensation to enable the properties to be as energy efficient as possible 

We were the Mechanical and Electrical contractor on this project

Installation of Gas boiler, Heat recovery ventilation system, Domestic hot and cold water services 

Mechanical Installations







This was a Full Design and build project working along side Allen architects and RV Rart builders.

A new gas Boiler has been sized and installed 

The heating system comprised of radiators controlled in multiple zones to ensure the building is as user flexable as possible

Domestic hot water storage has been provided to loft mounted plant space utilizing a horizontal cylinder 

Heat recovery ventilation system has been installed in a building with many level transitions. A mixture of square and pre painted powder coated ductwork was required.

Multiple automatic fire dampers had to be installed to provide fire compartmentation through the transitions.

We were the Mechanical and Electrical contractor on this project.
