OVSOL System This manual provides installation instructions for OVSOL System for solar domestic hot water heating. The OVSOL solar energy system described in this manual, when properly installed and maintained, meets the minimum standards established by the SRCC. This certification does not imply endorsement or warranty of this product by the SRCC.
Tubes are installed as the last step. Oventrop Corporation will not be liable for burns or personal injury due to the touching of a hot condenser. Handle the tubes with care to avoid accidental bending of the heat pipe at the condenser which may cause damage to the heat pipe or the vacuum seal.
There are many ways to design a solar hot water system to achieve the same end result. The two system types that Oventrop uses are external heat exchanger systems (i.e. the Regusol X) and Immersed coil heat exchangers (i.e.
Page 7
Another way to think of solar storage is as the fuel tank of the system. It is used to store energy that can be used over the entire day. In this way the daily load is matched to the daily collector output. Oventrop solar hot water systems are designed to optimize the transfer of energy from the collectors to the solar storage vessel.
Page 8
The design limits for the Regusol-X are based on the pressure drop through the heat exchanger, the pump capacity, and the maximum output of the heat exchanger. The table below lists the maximum number of collectors allowed to be used with each Regusol-X. For Single Speed Pumps Maximum number Maximum number...

Oventrop Solar Systems Sizing Chart The following solar sizing charts shows various combinations of solar collector quantities to Regusol pumping stations an the design solar storage volume. Tank selections are up to the designer for Regusol X systems and larger.
Collector Layout, Orientation, and Siting Place the collector where it will receive the maximum amount of sunlight available in your location. OVSOL collectors may be installed on a roof, against a south facing wall, or on the ground.

A tilt angle of 50° or more is necessary in regions of heavy snowfall and accumulation. Tilt angles of 50° and above will shed snow from OVSOL evacuated tube collectors even after severe storms. It is critical in heavy snow areas that the collectors be sloped to at least a 50° tilt angle. If collectors are installed on a fl at roof in an area which receives heavy snowfalls, the lower end of the units should be at least 18”...

Piping the Solar Tank with Integrated Back-up as a One Tank System Use 3/4” copper pipe for plumbing the tanks. To prevent heat loss through the copper tubing, insulate all tubing with at least 1/2” wall tube insulation. This should include the cold water feed to the solar storage tank up to 6 feet from the tank.
