All boiler systems have some type of cross connection control device to separate the boiler water system from your drinking water.  These devices need to be tested every year.  However, your boiler system also requires maintenance every year.  Calgary Radiant heat offers both of these services at one low rate.  We are certified to supply your boiler maintenance and test your cross connection device.
