Co Offaly based Grant Engineering has opened its newly expanded facilities in Birr after a capital investment of €14m.
The new facilities include a Research and Development innovation centre, a customer services centre and a dedicated training academy.
The company has also extended its manufacturing facilities and has further invested in robotics and automation.
Grant's expansion comes on the back of increased demand for the company's heating products on a local and international level.
The company today also said it had developed a new hybrid technology called EVOLINK which will be available later this year.
EVOLINK enables the smart integration of heat pumps to a property by combining with existing technology in a home whether oil, gas or biomass.
"The EVOLINK hybrid can play a substantial role in the transition to full decarbonisation of residential heat as will biofuel," commented Grant Engineering's founder Stephen Grant.
Mr Grant said the company has future-proofed its products over the last five years so that they can operate using biofuel, but to aid transition and further reduce emissions we need the support of fuel suppliers and the government.
"Hugely important to the local economy, Grant Engineering is an excellent example of an innovative, regionally-based company with global ambition that has expanded its reach to build a robust business in the face of challenges like Brexit," commented Enterprise Ireland's chief executive Julie Sinnamon.
"This new R&D Innovation and training facility will enable Grant Engineering to continue to grow, and we look forward to continuing our work with the team both here and through our international office network as they progress on this upward trajectory," she added.
