Case Study - Preston Council, Harris Museum





13,248 kg

EndoTherm was trialed by Preston City Council at the Harris Museum.

Opened in 1893, the museum and art gallery is a grade I listed building located in Preston City Centre. It also houses the city’s public library.

The museum, which covers 4 floors with large ornate period radiators is heated by 4 x Potterton Avon 2 boilers, each with a max output of 200kW. 32L of EndoTherm was installed in January 2016.

A direct comparison of the usage from AMR (actual meter readings) was taken by the energy management team at Preston Council and compensated with data from Blackpool Airport (baseload 15.5°C).
