Supporting clients to meet new challenges

Our public and private sector clients face new demands in terms of decarbonisation alongside the need for robust, cost-effective heating and hot water systems.  We help them achieve these multiple goals through the design and delivery of efficient systems that can both incorporate renewable elements or move completely into heat pump solutions.  Utilising our patented technologies, these system offer significant benefits.

Major benefits for customers:

Accurate flow control in both cold and hot water systems

Improves user experience, whilst reducing water and energy use

Cuts carbon emissions

Reduces capex and opex costs for building owners

Eneraqua supports clients to replace end of life gas, oil or electric heating systems. The Company is technologically-agnostic, offering the full range of communal/district heating solutions utilising high-efficiency gas, ASHPs, GSHPs or hybrid systems.

The focus on Net Zero among clients means that the Directors believe that ASHP and GSHP systems will be a substantial source of growth for Eneraqua in the future.

Clients are advised on the best solution based on their budget, any available incentives and the building layout with the typical options as follows.

GSHPs are the highest carbon saving option that the Company offers to clients. GSHPs utilise the natural geothermal gradient to heat a water and glycerol solution as it is pumped through a closed-loop down to a depth of over 150 metres. The solution is then pumped back through individual heat pumps in homes to provide heat and hot water to the property. The drawing above shows the type of shared-loop systems that the Group designs and delivers for apartment blocks.  An individual ground source heat pump is installed in each flat and this utilises heat from a shared loop in the block.  

ASHPs extract heat from the outside air into a liquid refrigerant at a low temperature. The unit utilises a compressor to increase the heat from this air and the heated liquid is then used for space heating and hot water.  

The installation cost will be lower than a GSHP system but it may not be possible to install with apartment blocks due to external space constraints.  have a lower installation cost and do not require as much space as a GSHP network. However, they are more expensive to operate than GSHPs and space constraints can limit applications for a block of flats.  In addition operating costs can be higher than GSHP systems.  

Gas-fired systems can be combined with commercial ASHPs to create hybrid communal or district heating solutions. These have lower carbon emissions than pure gas systems but otherwise operate in the same manner.  They can offer a good option where space or budget constraints preclude a pure GSHP solution.

Modern high-efficiency gas-fired communal/district heating systems can offer substantial energy bill and carbon emission savings compared to legacy gas systems. Gas-fired systems have lower installation costs than heat pumps but do not offer the same level of carbon savings.

Given the long-term nature of these systems, many clients are now looking at low-carbon solutions in order to respond to the 2030 Net Zero agenda
