Hoval adds security and efficiency to National Gallery’s heating system

Two Hoval UltraGas condensing boilers have been installed at the National Gallery to support critical environmental control and improve energy efficiency. Nigel Back of hurleypalmerflatt explains, ‘The base heat loads are met by a CHP unit, but the existing back-up boilers were oversized for meeting additional heat loads, resulting in inefficiencies. We therefore designed a system that would be more efficient and responsive, while also providing the resilience required to maintain the critical internal environment.’

The new system was installed by Capri Mechanical and uses the two UltraGas boilers as lead boilers, supplementing the CHP plant at times of peak demand. These boilers have a pre-mix burner with up to 12:1 turndown.

Three dual-fuel SR -Plus boilers have been installed to ensure that heating can be maintained to protect exhibits if the gas supply is interrupted.

In parallel, the heating system has been reconfigured, replacing the existing single-circuit system with a primary circuit and several secondary circuits to provide better control.
