School gives underfloor heating a good report

Giacomini
Giacomini underfloor heating on two levels of this new school in York simplified the installation programme and is achieving more effective and economical heating than wall-hung heat emitters.

Giacomini has supplied underfloor heating covering 9500 m2 on two levels of the new Manor CE School and Performing Arts Centre in York.

M&E contractor H&C Moore installed the systems, having worked with Giacomini on two previous contracts, both of which had special difficulties to overcome.

The installation required an array of manifolds and pumps to serve each heated area. The zones are controlled by tamper­proof thermostats. There is 31 km of 18 mm PEX pipe.

The ground floor is insulated with 50 mm of 100HDN materials. The first floor includes 25 mm of EPS 100 insulation and a 5 mm sound deadener. The installation was completed with 75 mm of fast-curing Mapie Topcem screed.

Alec Esgate, contracts manager with H&C Moore, says, ‘We believe that the installation of underfloor heating is easier than heat emitters because the bulk of the work is carried out as a first-fix item as floors are laid. Other than piping to manifolds, the installation is not reliant on numerous other trades — nor the site-management headache of getting them all in and out on a tight schedule.’

Operating at lower flow temperatures than wall-hung heat emitters also enables underfloor heating to achieve lower energy consumption.

More refrigerant bans possible, says government

The government could tighten up the rules that restrict the use of global warming refrigerant gases including speeding up phase-out programmes and introducing new bans, according to a spokesman from the Department for Environment, Food and Rural Affairs (DEFRA).

Baxi research suggests schools strongly support heat decarbonisation

A survey conducted by Baxi of 200 state school estates managers, consultant engineers and M&E contractors has found that while enthusiasm for Net Zero and support for low carbon heating systems in schools is thriving, persistent barriers remain.
