Do You Own a Solar Thermal System?

Solar Thermal Systems supplement your home’s domestic hot water and heating systems. Fluid is pumped through large collector panels on the roof where the fluid is heated. The heat is then transferred and stored in the hot water tank. These systems were popular in the 1980's, but many systems are nearing the end of their design life span. As a result, these systems often require extensive maintenance and costly repairs. Many solar companies don’t know how to properly maintain, drain, and detach these systems without damaging your home’s domestic hot water and/or boiler systems. The ‘roof plumbing circuit’ holds high temperature, high pressure, and potentially toxic fluid that takes experienced technicians with specialized equipment to safely drain. That’s where Vanguard Solar comes in.

Solar Thermal Hot Air Systems

Solar Thermal Hot Air is a simple type of heating system that connects to your home’s HVAC system to supply additional heat whenever the sun is shining. This heating system only requires a blower, saving you energy during the day. A lot of these systems were built in the 80’s and early 90’s and are becoming aged and need to be serviced to ensure that they are functioning properly. Few new systems are installed due to Solar Electric Systems being more cost effective and easier to service and maintain. These systems have no energy storage; they only work when the sun is shining AND you need space heating.
