An advanced communal ambient loop solution using in-apartment heat pumps to provide building services to residential apartments.
Get in touch
This innovative system has been designed in conjunction with leading industry developers, recognising the need for a new, highly efficient communal solution for residential apartments.
The Zeroth Energy Systems takes a compact, in-apartment water source heat pump, ambient loop solution and central plant to offer heating, hot water, and comfort cooling to apartment developments as a commercially and advantageous solution.
Suitable for offsite prefabrication, including utility pods
Flexible choice of plant technology, apartment controls and hydronic emitters
Up to a 50% reduction in plant room footprint
Reduces overheating in communal areas and peak heat losses by up to 90%
Cost effective comfort cooling through a two-pipe system
System efficiency of greater than 300% when modelled with an air source heat pump in SAP 2012
The advantages of heat pumps are available across multiple applications but are best placed in well-insulated buildings where the heat pump effects on furthering the building efficiency can be realised. Apartments can benefit from a system where all the heating, cooling and hot water supply is provided by an in-apartment heat pump.
A heat pump may also be integrated with a specific function, such as mechanical ventilation with heat recovery, to maximise the energy cycle. The system can work together with another energy source, such a traditional combustion boiler but also integrate with a fully renewable source like solar PV system. In addition to the primary function of a heat pump to deliver HVAC services, the excess energy generated can be discharged into thermal storage systems, or buffer tanks, to provide a more efficient on-demand service for heating and cooling without the need to short cycle the system when the demand is low. This creates a more efficient and sustainable communal ambient network.
The Zeroth unit is a water source heat pump which connects to an ambient water loop designed at 25oC. This loop is kept within operating temperatures by a central plant.
