OverviewThe WTS-F2 solar collectors are specifically designed for overlay roof installations and flat‑roof mounting. This collector variant is suitable for domestic hot water (DHW) production and as heating support, for both multi‑dwelling and single‑family installations.
Energy performanceWeishaupt collectors capture direct and diffuse solar radiation. For heating support, four collectors with a gross area of 2.51 m² each are sufficient to cover the needs of a 120 m² dwelling. If the solar installation is dedicated solely to DHW production, two collectors are typically sufficient for a three‑person household.
Design and constructionThe Mirotherm multilayer coating maximizes recovery of direct and diffuse solar radiation. The aluminium frame is welded and the solar glazing is bonded to ensure long‑term stability.
Product advantages- Welded aluminium frame and bonded glazing for dimensional stability.
- Long service life: integrated compensators in the hydraulic connections to absorb material expansion.
- Good solar efficiency to help reduce energy consumption.
InstallationThe collectors integrate easily with different roof architectures (pitched overlay roofs and flat roofs). They combine with various heat storages and tanks (e.g. WES 660 or WES 910 multifunction accumulators for heating support; WAS Sol dual‑coil cylinder for DHW production). Various financial incentives may be available for retrofit solar installations.
