12 years ago, Colmac Industries shipped their first batch of heat pumps, 4 x HPA4-PBSC, to Admor HVAC in Hawaii. Since then Colmac has shipped over 2300 units around the world. During this time, Colmac Industries grew into the Colmac WaterHeat brand and strove to improve the product by adding the water source line, and improved the reach of the company through the addition of factory representatives all over the world. Colmac WaterHeat would like to take this opportunity to thank everyone who has helped make this possible.
