WHAT ARE THE ADVANTAGES OF EVACUATED TUBE SOLAR COLLECTORS VERSUS FLAT PLATE COLLECTORS?
Easier Installation – One person can quickly and easily install an evacuated tube collector panel without a hoist or special tools because the vacuum tubes, manifold, and frame are installed separately. This unique feature results in substantial savings in installation time and expense. This is not possible with most flat plate products because of their one-piece construction. Superior Insulation – As any good thermos bottle proves, there is no better insulator to heat transfer than a vacuum. Evacuated tubes provide excellent resistance to heat losses through conduction and convection, even under extreme environmental cold winter temperatures and wind. Flat plate collectors lose a considerable part of the heat energy collected back to the environment. Easier Servicing – Since the evacuated tubes are installed in the manifold via dry connections, any tube can be replaced without shutting the system down. Flat plate systems must be shut down and drained. Longer Life – High vacuum protect
