Celebrating a COOL 24 years in business!



Constant heating and hot water without FIRE!

With rising energy costs it makes sense to install a heating and hot water system which consistently offers low running costs – protecting your business from volatile heating fuel prices.

With over 20 years experience in heat pump technologies, it’s only during the last decade that manufacturers have developed air to water heat pumps which provide a simple yet effective, renewable solution that rivals traditional heating systems.

As an approved installer of Mitsubishi Electric’s Ecodan and Daikin Altherma heat pumps, air cool engineering (NI) Ltd can offer businesses ‘air to water’ systems which deliver superb efficiency, advanced control, complete design flexibility and of course, constant heating and hot water.


  • Deliver renewable energy to meet renewable targets
  • Flexible control and zoning
  • Significantly cut running costs and carbon emissions
  • Offer easy design and installation with minimal maintenance
  • Provide scalable solutions able to work in conjunction with other systems
  • Suitable for new build and refurbishment

Perfect for: hotels; B&Bs; care homes; health centres; surgeries; schools and restaurants.

Enjoy constant heating and hot water!

The Ecodan and Altherma systems are affordable alternatives to existing fossil fuel heating equipment, so if you are building new premises or thinking of replacing an existing boiler, now is an ideal time to consider the heat pump technology.



Air Source Heat pumps are the most efficient way to power wet underfloor heating systems. Unlike a gas or oil fired boiler, which heats water to between 65 and 85°C, heat pumps generate hot water to temperatures between 35°C and 45°C. Our choice of award winning heat pumps can effectively produce and efficiently maintain, optimum hot water temperatures for floor heating.

For over 5 years, air cool engineering (NI) Ltd has integrated the Mitsubishi Electric ECODAN and Daikin Altherma air source heat pumps with the REHAU underfloor heating system. In contrast to conventional radiators, Rehau’s floor heating provides cost-effective comfort levels and ensures a uniform distribution of heat across a large heat emitting area. Our confidence in our heat pumps and Rehau’s underfloor heating system, makes a winning partnership in the heating and hot water market.
