Boilers & Hot Water Systems
High Mark Mechanical specializes in Installation, Service, Repair, and design of all radiant heat systems and equipment. Boiler replacement, gas conversions, leak repair, control work, piping leaks, and annual safety checks are what we do.
Radiant or Hydronic Heating is defined as utilizing hot water to heat the space in your house. This means that water is circulated through pipes from a heat source like a boiler or water heater to either free standing radiators, baseboard radiators or under-floor pipes. The water is used to transfer heat from the heater to the rest of the house as opposed to warming air directly. This type of system is very quiet, very efficient, doesn’t move dust around and has a very long life span. It is space saving and suitable for retrofit of older buildings due to the smaller in-wall, in-floor space needed for pipes (instead of ductwork).
