Three Story Extension

Lambert and Macfarlane carried out the refurbishment to the existing Underfloor heating and installed a new 70kw boiler with low loss header for zoned areas on the ground floor of the existing Manor, the new extension comprised of a new LTHW heating system with radiators and underfloor heating, all heat emitters are fed via manifolds and controlled by Heatmiser controls system for local and remote control of the heating and HWS system in the main house and the extension.

‍

The new oil fired boiler serves a vertical low loss header, the circuit will serve the existing heating and hot water circuits to the main house and serve the new heating and hot water circuits to the new extension via the below ground pre insulated heating mains running through the garden and entering the extension via the basement services cupboard.

The existing heating circuits serving the main house have been extended from their previous position within the rear entrance to the new boiler room maintaining the existing pipework line size.

The new boiler serves both the existing heating circuits to the main house and the new space heating and hot water cylinder within the new extension, one pump circuit serving the main house and a second pump circuit serving the extension.

A new 12 manifold positioned in the boiler house cupboard feeds existing Under Floor Heating circuits within the Manor

The second circuit from the low loss header within the boiler room serves the space heating and domestic hot water cylinder within the new extension. Space heating within the extension is a mixture of underfloor heating to the basement and ground floor, and radiators on the first floor and link areas.

New HWS cold-water services fed from main supplies and ran to supply the new bathrooms, WC and kitchen within the extension.

Domestic hot water return systems (DHWS R) installed to maintain adequate pipeline temperatures and limit waste water and storage.

The basement floor level is served by a MVHR (Heat recovery) unit, which supplies and extract air from both the laundry room and toilet.

The first floor en-suite extract is served by dedicated inline extract fan positioned within the roof space.

The new soil vent drainage systems serves the new Titcomb extension for the discharge of foul and waste water, The system is installed to minimising the risk of blockages and provides adequate ventilation to all stacks and branch pipes to ensure effective drainage of liquids and solids in all parts of system.

Soil and waste drainage systems comprise primary stacks with discharge branches.

Secondary ventilation pipes are used for longer runs or where siphoning may occur.

Pipework installation has been installed in such a way as to minimise noise transmission to adjacent spaces. Acoustic separation is provided between pipework and structure.

Access has been provided at all changes of direction and above the connection point to the below ground drainage. Main soil/waste vent pipes rise to roof level and terminate via a vent tile.
