A heat pump for high outputs

A heat pump for high outputs

In recent months there has been considerable interest in increasing the use of heat pumps as part of the UK’s decarbonisation strategy.

Much of this interest has been focused on the residential sector but many public and private sector organisations could also benefit from this technology. However, in many cases the outputs available from existing heat pumps were too low to provide a viable cost/benefit ratio.

Now, Hoval has addressed this issue with the launch of the Belaria fit range of air/water heat pumps – for use in standalone configuration, in a cascade of up to 16 units or as part of a hybrid system. They can also be retrofitted to existing heating systems. In all cases, these new units deliver efficient heating, cooling and domestic hot water (DHW) production at the same time.

High efficiency is the key to meeting the demands of systems with high outputs and a high proportion of renewable energies. This is achieved through advanced design, which includes modulating inverter technology that enables continuous adjustment from 40-100% of load, ensuring optimum energy efficiency at all times. Additionally, the hydrophilic coating on evaporator fins maintains consistently high efficiency and shorter defrosting times.
Further efficiencies are achieved through the use of R32 refrigerant, which has a high volumetric refrigerating capacity and is ideally suited to the UK’s temperate climate. The result is high Seasonal Coefficient of Performance/Seasonal Energy Efficiency Ratio (SCOP/SEER) for heating and cooling. Consequently, systems with Belaria fit are considered sustainable and are eligible for subsidies.

Hybrid systems

It is anticipated that the Belaria fit will be particularly attractive for use in hybrid systems, where they can cover the base load of the entire annual demand. The additional heat generator is then only used to meet peak demand at low outdoor temperatures and/or increased DHW demand.

In addition to the clear environmental advantage, hybrid systems offer:

  • Increased efficiency, as the advantages of the energy sources in terms of output and temperature level can be used selectively.
  • Increased working safety due to redundancy of heat generators and reduced dependence on a specific energy source.
  • Lower investment costs for the additional heat generators.
