Daikin Altherma pumps up the heat at Belmans Court

Residents of the Belmans Court sheltered housing scheme at Dovercourt, Essex, can look forward to cheaper, warmer and greener homes following a switch from electric storage heaters to Daikin Altherma low temperature heat pumps.

In a 10-week installation programme, Colchester-based Daikin installers Blue Flame Services fitted 45 heat pump systems and 150 radiators in the two storey development on Deane’s Close.
Blue Flame project manager James Mealing says the new system is 300% more efficient than the storage heaters, putting residents on their way to a forecast reduction of more than 50% in energy costs.

Built in 1989, Belmans Court consists of 42 flats, a two-bedroom two-storey unit and communal facilities including a lounge, laundry room and guest room.

After 25 years’ service, the storage heaters fitted throughout had become expensive to run – and by modern standards, they were inefficient and outdated. Tenants’ hot water was heated separately, by immersion heaters.

Deciding it was time for a more affordable and environment-friendly heating and hot water solution, Tendring District Council, which operates Belmans Court, teamed up with nationwide heating specialists ICE Energy to secure government funding.

Belmans Court became one of the last projects to receive the Renewable Heat Premium Payment (RHPP), which was superseded by the Renewable Heat Incentive (RHI) scheme in April 2014.
James says Daikin Altherma low temperature split systems were specified for performance, reliability and ease of installation.

Two 16kW units serve the communal areas and a 6kW system operates in the two-storey unit.  Each of the flats has a 4kW unit. All the systems are highly efficient, with the 4kW units having a Coefficient of Performance of 5.04 (tested in accordance to EN14511 at  ambient air 7oC, water temperature 35oC). 

The Belmans Court systems are configured to provide  a  water temperature of 48oC to the radiators, providing a good balance between comfort and economy.

The installation required careful planning to meet a tight overall deadline and to minimise inconvenience to the tenants.

Before work started on the project, representatives from Blue Flame, Tendring, ICE and Daikin UK met with residents to discuss the project and explain the new heating system.
